This happened to me on a jump load in FL in the 90s. I was last out of a Queen Air, in a 2 way, after a 5-6 way before us. One minute I was in the doorway, the next I did a face plant on the floor and couldn't get out of the damn a/c. I recognized the stall/spin as it was happening but just couldn't get out of the door (above me then below me than above me...) . Thankfully the pilot recovered and we went back up to altitude. I asked later "WTF?" and he said "traffic". Checked that one off my bucket list. Only 8 lives to go.

[@tufiremn]

I know this is an old video, but I just saw it and it brought back memories of being in a C90 that stalled on approach at 2500’ AGL in IMC. We were a medivac coming back to our home field after a transport. ATC had kept us high due to being between two larger airports, and the PIC was angry with ATC because of this. He had the gear down, full flaps, and throttles at idle to slow down and attempt to lose altitude in order intercept the localizer. Problem is that when he did pickup the localizer he pulled back, lifting the nose and the IAS dropped to 70kt. Things got quiet, stall horn was screaming and the wings buffeted. Now we had issues with this pilot in the past, so luckily on this flight there was an observer pilot in the right seat who took the controls, nosed over hard, and firewalled the throttles. The recovery was quick, and we went missed, but landed safely on the next approach. The worst part is the PIC would not admit that he stalled the AC. He was terminated on the spot.

[@omniryx1]

When I was working toward my ATP, I flew King Airs and Caravans for a skydiving school/club. Jumpers perpetually complained to the boss because we would not pull the left engine on the King Air to idle for exactly the reasons Juan discusses here. Lots of pilots love the KA but even it's most ardent admirers do NOT want to get it into a spin. Fortunately, the old man backed us up. After my time, he dumped the King Airs in favor of Caravans and a Kodiak. Not as fast but a whole lot more forgiving. They also give you a great way to get the floaters to stop hanging on the rail. It is usual to put your foot on the left wheel brake. This lets the forward jumper put their foot on it for stability. Those folks start dawdling around out there? Just release the brake. Bye bye.

I saw a jumper have that falling off the wheel experience from a C-180, but unintentionally due to a failed brake. I reached out to give it an extra spin, the pilot stomped the toe brake to no avail. I told him "Have fun landing this!" and went out the door.

The last jumper out was Jana Neimoller. She said she was was initially thrown around the aircraft with nothing to hold on to, and ended up flat on the floor near the door. Then was thrown out involuntarily.

[@andrewrivera4029]

Yea once the group spread out a little there were more than 6 bodies in the air not including the camera man.

[@thomasaltruda]

Flying jumpers in a Twin Otter, yes, we would reduce power on the left engine to reduce prop blast, and use rudder to compensate. I wouldn’t go to idle, just reduce it some.. you don’t want the left prop be be a disk, you still want some air flowing through to help the jumpers “fly” their exit. Pretty normal. The jumpers also need to be aware about causing an AFT CG that could cause controllability problems. The Otter happens to be a more forgiving plane than the Kingair though. There was a similar incident in the PNW where one half of the Horizontal Stab came off in recovery. That plane got fixed, and eventually went to to get destroyed in the Hawaii accident.

With 20+ years in the sport I've always had the highest respect for our pilots. They operate under difficult and demanding conditions. Serving drop zones the world over every weekend without incident. It's a bit of a shame that the only time they hit the headlines it's usually negative press. More power to them I say, and blue skies! We are all learning every day :-) Thanks Juan, as always, brilliant content!

[@zak2u2]

With nearly 50 years as a professional pilot and being USAF trained, I along with many other pilots think the reputation of jump operations and their pilots is sketchy at best. I'm sure you think your pilots are great. Passengers usually do. This pilot in his deposition demonstrated a severe lack of knowledge of aerodynamics. In the pilot world, jump pilots are thought of as hot dogs. Quite often they are relatively low time pilots working cheaply to build twin turbine time. And of course you only read about the negative incidents. But there shouldn't be so many. This is why Juan said that the NTSB and FAA have been paying close attention to jump operations.

[@rotten007pig]

[@andysgoodtime630]

Hey Juan, king air 200 and 90 guy here. I’m kinda blown away by the way they have this procedure written. I think what I have to say about this incident is that people are reading “course pitch” what you should read is FEATHER. The reason it took one engine to “spool up” is cause the left engine with prop feathered needs more time for the prop to come OUT OF FEATHER and go into positive pitch. It takes time. Anybody that knows the king air or indeed the pt6 will tell you that it takes time to bring that prop from feather to full fine and ready to pull. And that would be reflected in the differential thrust described in the written article. BE90 speeds that are relevant VF 174 VFE130 VMC93 Something like that The 200 is better in every way. And the 300 is probably better than that and so on. Coming from a northern gravel king air guy.

[@DARANGULAFILM]

In one of Juan's frame grabs early in the recovery attempt, you can see that the port propellor pitch is finer than the right. Having a twin engine food processor sharing the same airspace with my unprotected carcass would scare the hell out of me.

[@blancolirio]

Thanks Andy!

[@SciFly7]

Oh yes I was making the same point before I saw your reply about the "feather" condition of the left engine. I think some multi engine and constant speed prop operations recurrent training might be due here.

[@stay_at_home_astronaut]

These kind of dumb4ss3d procedures get passed down from one low-time pilot to another and are even requested by the jumpers.

[@andysgoodtime630]

@@DARANGULAFILM I can possibly explain that. When you have a propeller feathered and ask it to go to full fine while adding full power the propeller has a tendency to overspeed. King air 90 props are meant to be governed between I think 2200 and 1900 rpm. So when you shove it from feather… around 400 rpm to fine… around 2200 rpm. The thing has a bit of momentum, if you will towards the high pitch. The prop will momentarily over speed before the governors catch up. Mechanical connections and mechanical logic. It all takes time. That’s why we have governors. 3 actually and if you’re suggesting that the right hand prop was in a “finer or more high pitch state” I don’t what to tell you. Something is wrong. Because to perform this manoeuvre without one engine ready to go I.e. high rpm(fine pitch), seems silly to me. I understand you have thousands of feet to recover but I was always tought to operate these airplanes and any airplane in an envelope that they can work. This seems to be pushing that envelope to the max and in this case beyond. What if those divers inside had whacked their had and gotten hurt and the other obvious what if’s that arise.

[@gregorylewis8471]

I imagine the five (then four) skydivers left inside the aircraft during the spin(s) would've been flopping around the cabin. Lucky that at some point they didn't all crash into the cockpit! Great report Juan! Loved the the T stuffer at the end!

[@hud86]

Former jump pilot with A90 and BE-99 experience: too many people got aft on this one, pilot would have had to fly so fast to keep that many people on the tail they would have blown off. Poor recovery after spin entry, but I blame the jumpers for loading up the tail too much. Not a lot of elevator authority at slow speeds and a narrow CG range in the Beech's, gotta fly 100-120kts to have big ways hangin on the tail with less flap

[@skydive1424]

You’re absolutely spot on! As a skydiver and former pilot, I’ve seen many times that jumpers pile up in the door and on the outside grips. Even with signs in the cabin “no more than x jumpers behind this line”. These guys are hyper focused on a well timed exit and ignore everything else.There is normally heavy buffeting due to the disturbed airflow over the tail with jumpers hanging outside which can mask a pre stall buffet. Due to substantial drag increase, its almost impossible to do this without a rate of descend or adding substantial amount of power. Doing a final jumprun this close to stall speed and below vmca is begging for it! I can not imagine that this has not happened a good number of times already, only this time is was caught on social media. In the skydiving centres in parts of the world I’ve been, the pilot lives in a bubble and formation jumpers do a exit dry run on a mock up with zero consideration for airplane controllability (“that’s the pilots job”). Briefing folks!!

[@xflyingtiger]

Having flown the King Air and the De Havilland Twin Otter I can attest to the fact that the King Air is not really a good jump plane (for the reasons demonstrated in this video). The Otter is a great airplane for this activity because of its high wing and very low stall speed. The engine and prop configurations on both aircraft are the same, PT-6 Pratt and Whitney. When the power is reduced to idle, on either aircraft, it is like putting on the brakes. The deceleration is very pronounced. The way this guy was flying the aircraft he was just asking for a stall/spin.

[@conorlauren]

[@RobertoRMOLA]

Recipe for a disaster (or such): - Put 16 people on board a King Air B-90 (the maximum certified number of pax for this model is 13, including pilot and co-pilot); - Slow down to 90 - 95 KIAS at high altitude (the "normal" Vref speed for a B-90 is ~100 KIAS on a stable straight flight approach); - Fly with no oxygen on a depressurized aircraft above 13,000 ft and "feel the joy"; - Totally neglect stall speed vs altitude range (the stall speed for landing configuration is 76 KIAS, but at ~5,000 feet and MLW, not at 16,000 AGL and who knows how heavy it was) - Fly with a crowd of "hi-drag" people holding onto a handrail OUTSIDE the aircraft, on the same side as the critical engine (left). - Do not read and throw all aircraft manuals out thru the window at the first opportunity you have, including that yellow "Beechcraft Safety Information" booklet which says a King Air should never be flown in a full stall condition as this is the ONLY guaranteed condition to avoid a spin on this aircraft type. The result, as far as I am concerned, was a real miracle, with its pilot trying to get out of a stall + spin pulling yoke back and sideways completely and oscillating wildly several times.🤦‍♂️ I honestly don't believe this aircraft is "undamaged", based on what we could see clearly: I've seen other King Air 90s in milder situations that suffered several bendings and warpings on wing and nacelles that could not be repaired (for unsuspecting future buyers: this is the 1968 Beechcraft B90 King Air S/N LJ-431 with registration number ZS-OHB which will probably be selling pretty cheap...). Considering the type of flight (skydiving) I can't say I'm "surprised" with such events... it seems that adrenalin is always required (and enjoyed) here.

I think "disking" of the prop means fully "fine" as a windmilling fine prop will act like a disk generating maximum drag which would exasperate the asymmetric configuration.

Windmilling is when the aircraft's momentum is used/wasted turning the prop, even minimal engine output means no windmilling.

[@montrellwalker1304]

Juan as a skydiver and a single engine prop pilot I can't thank you enough for the analysis. I'd imagine all the drag on the port side engine, while decreasing thrust on that engine would be a set up for disaster. While the pilot may have wanted to avoid the prop wash on the skydivers sitting outside the airframe, increasing the chances of a premature deployment and getting wrapped in the empennage (which would take everyone down) and I don't fly twins. Feels like a recipe for disaster if not performed correctly, the pitch up was an issue given asymmetric trust, I'm not an expert at Twins in any way and never trained in them. Your analysis is pretty spot on, I've been enjoying your channel for a while and appreciate this breakdown. I learn so much on your channel, I hope you keep it up and also break down these situations as well. Much appreciation for you.

@@Riverplacedad1 completely understand, however I have doubts that a group of skydivers would jump out in a random spot out of a perfectly flying airplane.

I am still studying hard and have zero hours of stick time so my opinions are not very valid, however I don't ever plan on getting in an airplane without ever planning out a route the night before carefully using the VFR maps, especially in unfamiliar route on a cross country trip. Modern planes have very good moving maps that should be current, but some good old fashioned studying and putting pencil to paper will always be a good fallback.

[@LiberTY7416]

In all the operations I have flown in, we always reduced the power to minimize propwash and sacrificed altitude if we couldn't maintain enough stall margin. At least in the singles I fly (Pilatus PC-6, Cessna 182) the decent rate is not that excessive that the skydivers will notice the altitude loss from start of drop to finish. I usually just request the next 500ft higher flight level and drift down during the drop.

T-2 for the Navy. We would do a coupled vertical entry to get an inverted flat spin. It would uncage your eyeballs but was a great confidence builder in spin recovery .

[@jesse-raybear-baldwin]

The only aircraft I intentionally spun was a Piper Tomahawk with my instructor. Neither of us knew at that time that the Traumahawk had that nasty habit of unrecoverable attitudes. We had a blast and survived - I learned how to recover from a spin and more importantly, how to avoid getting into one in the first place. I still think spin training in the right aircraft should be part of the curriculum for the private ticket. Medically grounded now so it really doesn't matter what I think ;-) Love the channel Juan!

[@Variety_Pack]

I've gone spinning in a Cessna 152, best times of my life. Better than sex, especially because you can tell your parents about it as often as you want. The 152 enters and recovers exactly when you want, like it's on rails. I've only got 20 hrs in (need a better job), but I think I've spent at least 2 of them just whirling around. My instructor thinks it's a blast, too, so we do it on nearly every flight even if its just practicing touch and goes (obviously far away and above 3k ft). Sorry you've gotten grounded, man. That's a huge bummer.

[@jahbern]

What would be the right aircraft to learn spin recovery in? My daughter just finished her private pilot and she only ever flew a Skyhawk. She has also flown a Piper Cherokee (a friend's plane). Her school didn't offer a ton of aircraft types anyway, but even so none of the others were available to the private pilot students.

I was fascinated by how the rudder became your pitch control during "that" moment in the maneuver. If I ever finish my flight training and acquire a single-engine land certificate, and type out in an appropriate aircraft, I'll have to try that, lol.

This popped up on my stalkbook feed a few days ago, great camera work from the jumper with the camera. As you said, pulling the left engine along with the additional drag on the left side from the jumpers and then the aft CofG change was just a recipe for disaster..luckily they were able to walk away from it.

[@SmittySmithsonite]

Been watching that video the past day over and over! That's about the best footage of a stall / spin and recovery I've ever seen! Crisp and clear, and the camera was on the aircraft the entire time, even climbing out from it! Must've been one hell of a ride for the skydivers!! Great info as always, Juan. I knew aft CG played into this, but I didn't even think of the guy's bodies all blocking the effectiveness of the elevator. Interesting! I also never knew they put one engine to idle. Even with my limited and fairly newfound aircraft knowledge, that sounds sketchy to me, too. The guys should be ready and expect prop blast when that door opens on a twin!

I dropped meatballs for a bit building time in a C90 with the Blackhawk PT6’s. I was never taught or asked to reduce power on the left engine. We would approach the DZ around 100kts, if I recall correctly, power back near idle, turn the green light on and pitch for 90kts. Flying that slow with asymmetric thrust with a shifting cg is a bad idea. It’s not a matter of if you will enter a spin, but when you will enter a spin.

Good analysis Juan. That Pilot was outside the limits and nearly cleaned up skydiver and himself. The Cessna 310s and 402Bs in a flat spin are a death trap for the exact reason you specified. The mains tip tanks become sustaining spin weights.

[@skippynj1979]

I flew King Air's in sky dive ops before I went to the Airlines. It was the most dangerous job I ever had!.... sketchy ops, mx.. minimal training, beat up planes with questionable histories... I flew 90 kts on jump run.. always kept symmetrical thrust... I can't remember power setting.. I'm pretty sure I never put flaps in but it's a little grey to me these days. ... We allowed 4 on the tail.. and that scared the hell out of me. Once had 5 or 6 on the tail and I could feel the buffet and had zero elevator authority. I went bizerk on the ground and parked the aircraft that day... IMO the king air makes the worst skydive aircraft I flew. I flew them all I think... it gets up and down quick... but that rear exit and aft cg and horizontal stab combo... ughhh I don't even want to think about it.. Never happened to me but had heard stories of high angle of attack with the jumpers on the tail entering the stall and the jumpers striking the horizontal stab. The specific STC for the king air I flew did not require a chute but other aircraft I flew did. There would be no way to get out in the king air anyway. It was crazy dangerous flying but man I could spot land that aircraft in a dime... plus energy management and flight idle from T.O.D 14k to touchdown was a fun skill that you naturally developed over time.. I would bet some of the senior sky diver instructers I could touch down before them... it was fun. But after almost a decade of airline flying... I would never do that stuff again..

Center of Gravity and airflow disruption has always been a factor in flying jumpers. Some jump pilots and some jumpers understand these effects and do a good job of compensating. Other pilots and jumpers are less knowledgeable and less safe. A particularly difficult jump plane that I jumped a few times back in my mis-spent youth was the Lockheed Loadstar. The exit door was quite far back. Too many jumpers near the door on exit could stall the aircraft...there were fatalities.

[@dennisparks3692]

was that back in the 80's ?

[@fast_richard]

@@dennisparks3692 Mid 70s at "the Gulch". I don't think they ever had an actual crash there, but I had friends who bounced off the tail in a stall event. The fatal Lodestar crash or crashes were elsewhere. The Lodestar stall tendency was well known and jumpers were briefed on how to exit without having too many people behind a specific line, well forward of the door.

I don't have a lot of experience flying jumpers and what I do have is in a single engine, but the notion of putting the left prop to full flat pitch is insane. Glad to see I wasn't the only one to notice the two secondary accelerated stalls in the recovery. After posting a comment on another video I heard from someone who knows the pilot claiming he's very careful. After listening to your break down I'll stick with my original thoughts. I'd also say he was lucky he didn't try to cobb the power on the recovery. No two PT-6's spool at the same rate!

[@kurtdobson]

I had a chance to fly as a passenger in a Cheyenne II from Burbank to SLC. I knew both the pilots who had not flown together before. On final in SLC, there was a significant cross wind and the pilot said 'let me show you a trick' to the second pilot; instead of using rudder, he simply backed off the thrust from one engine and was very proud of how nice a normal attitude on final was compared to lots of rudder and slip. But on short final, the tower called for a 'go around', and without hesitation the pilot went full throttle on both engines. Problem was that one engine spooled up quicker than the other and the airplane really went sideways (thought we were gonna die). Not sure how he saved it but it took all the rudder there was along with a few prayers. Both pilots were sweating bullets when we finally got on the ground.

I've only jumped out of aircraft in the US Army. C-130, C-141 and a CH-47. Of course since those aircraft are considered overpowered for airborne jumps, I never felt like the pilots were on the verge of loosing control.

Not a king air guy here, but rather a spin demo pilot at Randolph in the mid late 90s. Had the pleasure to see some inverted spins at Edwards in a previous gig in an A37. We were chasing them from a T38. Seemed to me it took quite a bit of effort to even get into the inverted spin, and the likelihood that would happen in a tweet seems low to me, yet possible if deliberate enough. Idle-neutral-aft. Pretty much kills the inverted spin right there. Your left in a dive, easy to recover. The tweet would recover stick only or rudder only. 2 of the 6 demos in the spin demo ride. Just wasn’t as efficient as the regular boldface method. (The test guys were getting into an inverted spin by rolling upside down, then doing an inverted stall with feeding rudder as they approached the stall. The result was kind of a cartwheel looking thing into an eventual inverted spin, usually, and they had to hold the stick forward to keep it from recovering. With the airflow issues at altitude and that high pressure ratio engine, they often lost one or two engines as a result, to be restarted after the recovery. The reason I state this is that I have heard tales of IPs and students saying they were in an inverted spin in a tweet, and that is highly unlikely as the setup is pretty lengthy and deliberate. The ones that usually claim it say that they held the stick forward too long in the normal spin recovery and overshot the recovery cone to the negative, or inverted, side. While it may have looked a lot like an inverted spin, I would classify this as more of an inverted snap roll, although technically still aggravated by a large difference in lift between wings, at this point your total speed would have been pretty high and once you pull back a little on the stick the rolling would stop. So to say you were in an inverted spin in that case would be like saying that an upright snap roll was also a spin... Similar, but not my idea of a traditional "spin". I'm sure folks will say I'm wrong, which ain't uncommon... In all cases, regardless of how you got there, once you are inverted and getting tossed around in a negative environment, it ain't a fun ride). I rambled too long there... Looks to me like the king air here kept aggregating his recovery. Probably more freaked out at the dive than anything. And I’d bet he still had asymmetric thrust at that point, so a deep secondary stall was resulting in more of a snap roll than an actual secondary “spin”. Still basically the same thing. Idle…Break the stall, kill the rotation, you’ll come out. Take your time in the dive recovery. Glad they didn’t hit any jumpers during this little snafu. Makes for good stories. Danger Builds Character!

[@gordonelwell7084]

Tweet IP here . . . inverted spin twice (both unintentional, since it was a prohibited maneuver). First was with a "spin pilot" while at PIT. I screwed up one of the stick only recovery attempts and left it full fwd too long while still in a normal spin. Slipped right into a full neg g inverted stall (and still spinning) ended up in inverted spin. In step 3, I went stick full fwd to decelerate the spin, then snapped it full aft. Nose came around and was in a straight stall. Just pushed the stick fwd and flew it out. The second time was with a student, and like in the first he held the stick full fwd too long and right into the inverted spin. I took the controls and just like the first time, step 3 popped us right out.

[@markg7963]

@@gordonelwell7084 the old negative spiral, I believe. Not the most comfortable ride😀. But technically you can’t get into a negative spin from an upright spin in the course of any of the recoveries demonstrated in a spin ride or by a student. In a stabilized upright spin the jet just doesn’t have enough inertia in the pitch axis to traverse to a negative stall as it transits the spin recovery cone. Negative, yes, spiral, kind of, inverted stall, no, thus not a negative (inverted) spin. As your pitch transits the spin recovery cone you almost instantly recover from the stall, and in that attitude you pick up a lot of speed through the transit of the cone. I suppose if you aggravated the forward pitch long enough eventually you could get there, it that would be several thousand feet and like an additional 30 or 45 seconds. In a student environment (not a test environment) this would be ridiculous to sit through, and nothing to gain by this experience. And flirting with an ejection altitude. Where I will agree with you is that the ensuing ride is a shitty feeling. And it’s very abrupt. It’s basically oranges and apples to discuss what it was anyway, as obviously it’s mis applied recovery by the pilot. Easy to do, not fun to ride through. And makes for great stories from back when we were still cool.

[@gordonelwell7084]

@@markg7963 I guess we will have to agree to disagree. Step 5 says "stick abruptly full forward one turn after applying rudder", then step 6 is "controls neutral after spinning stops and recover from dive". I just know that on both of my episodes, it was step 5 applied for an extended period that left us in the spin. I distinctly recall starting the boldface over after being in the inverted event, but in step 3, I intentionally put the stick full forward first (which decelerated the spinning) and only then executing the rest of step 3 (stick abruptly full aft and hold). I believe that if I had not decelerated the spinning by going full forward first, then the abruptly full aft would not have had enough authority to stop the spinning inertia and the ejection could easily been the next step. You are correct that both events really chewed up lots of altitude. I still think of myself as cool, but not in the same way . . . I'm cool today because I managed three great kids, and watch two great grandkids arrive on the scene. On a side note, my son is a US Navy test pilot instructor and he matter-of-factly told be one afternoon on how he had to take the controls of an F-18F from a test pilot student to get them out of an inverted flat spin.

[@danielstarnes7354]

Hi all, This pilot made a mistake and owned it in his lengthy and detailed explanation. More words equal more fuel for criticism. I've jumped out of many KA's, but have never seen 6 on the step. Did the pilot know so many were to exit at once? If not, he is ill equipped to give the thumbs-down during their climb-out; too late. At most DZs I've jumped at, it would fall on jumpers to inform pilot or S&TA before takeoff, or fall on management to limit group size for exits. Max 4-5 jumpers for CG reasons seems like a reasonable way to prevent this from happening again. While this was a close call, and unacceptable, it does not seem to come from a place of negligence on the part of the pilot, and he does not deserve all the blame. Good jump pilots of twins always try to minimize prop blast. Try flying jumpers, and try out 100+ knot prop blast while standing on the step. Pilots in the States wear a parachute because FAA regs say all passengers including pilot must wear a parachute when the door is open during flight. Thanks Juan for your thoughts and excellent content, I love your channel.
