The Propeller Fell off My Airplane

Last summer I fulfilled my dream of buying this homebuilt airplane and flying it halfway across the country. Unfortunately on my first major flight away from home I experienced an in flight crankshaft failure resulting in the propeller completely departing the plane in flight. I'm heartbroken to say this will be the end of my journey with this little plane. Above all I'm grateful that the situation resulted in a safe outcome.
The cause of the crankshaft failure is currently unknown. Since there were no injuries or property damage, the NTSB chose not to investigate. Some theories include improper assembly of the crank hub, fatigue cracks, or a blockage of oil to the front bearing.
Thank you all for the support and kind words on my previous video, it means more than you know.

Thank you all for your kind words, wisdom, and support. It has truly meant a lot to read through your experiences and feedback. I'm sad to say due to the reasons listed in the video along with starting a career and moving to a new state, it makes the most sense for me to part ways with this plane :( This certainly won't be the end of the flying adventures and I look forward to sharing more videos with you soon!

Hi Ethan, in France, a while ago, two guys made a small aircraft from scratch powered by a… turbo diesel car engine (the one from the Opel/Vauxhal (GM) Corsa, 1300 cm³ IIRC) which works very well - this was a _very_ interesting reading (although entirely in French) as the diesel engine add security (no magneto + higher altitude possible because of the turbo). One inconvenient is you hardly found gas-oil in each airport, two advantages are gas-oil is cheap and this kind of engine have a very low consumption. I don't remember if they tried it with A1, but it might be possible if it has the same octane grading or if it can be corrected with an additive. If you know somebody _very fluent_ in French or better, a French, who can translate it for you, he must look for : "brest avion moteur diesel opel corsa" and/or "Gaz'aile" (name of the plane, they know have the Gaz'aile II that is using another turbo diesel engine a bit bigger with more power). Their plans were agreed by the DGAC (Direction Générale de l'Aviation Civile, d° FAA but for France), which is a very good thing as only very serious state of the art constructions can get this agreement (one of the guy was engineer for the aviation, that helps ;-)

[@adamr9215]

There is nothing wrong with that plane, just something wrong with the engine/prop. If this made you afraid of the plane, then maybe flying is not for you.

[@hankhulator5007]

@@adamr9215 Wild guess, the engine model cannot be changed and from the video it is its shaft that broke, so I can understand he do not want to repeat this adventure. I don't fear many things (except the sky falling on my head as a Gaulois ;-p), but I wouldn't take the chances either, imagine the same over a large forest or with an endless ground full of big rocks. This is common sens, nothing else.

[@walter7671]

There are and were airplanes with a car engine, but a car engine is not ideal for an airplane. First of all, the weight of the engine must be taken into account, given that the plane has a calculated center of gravity, if the engine is more heavy the "natural" center of gravity of the plane is shifted. On the other hand, airplane engines do not have the same ignition system, they use magnets and these are autonomous, they do not need an alternator or battery. The magneto is as if it were a dynamo attached to a high-tension coil, but also since they use a redundant system they have 2 magnets, and 2 spark plugs in each cylinder. Obviously, in automobile and airplane engines, there are changes related to technology, I compare the basic carburetor engines and their aeronautical counterparts. Aircraft engines are usually engines with opposed cylinders and double carburetors, with a system to heat the carburetor air and mixture control, the latter also affecting the cooling of the engine while on the ground. Aircraft engines are usually cooled by air, a rich mixture helps by not raising the temperature of the cylinders as much when the plane is on the ground, and therefore the cooling is insufficient. Tons of differences and flight conditions make it convenient to have an engine specifically for aviation and also certified@@hankhulator5007

[@walter7671]

That's right, you can be more cautious and have a better plane, but "certified" planes also crash. As happened with Sam from Rebuild Rescue, although the plane had 2 engines, one failed and the plane fell, two engines do not help much either (although the Cougar has 2 engines, but they are not very powerful) Being prudent is good, but to save and have something very safe, you can do like John Travolta, buy an old Boeing 737 NG, they are very safe. Although he handled this emergency very well, a good pilot is not only someone who knows how to fly. He is someone with light mechanical skills, who does not take off without even checking that the fuel does not have water. It is also someone who practices with an instructor in certain situations that could happen. For example, when losing spatial orientation due to fog or something and falling into a corkscrew, many panic and kill themselves. Having an engine designed to be used in general aviation? That is being cautious, I hope he is not afraid of flying, that is the main thing after being cautious@@adamr9215

@ethanmcintosh1777 Former VW mechanic here. I worked on air-cooled VW engines for many years in the 70s and 80s. The crankshaft failure you experienced is a known issue (or at least, was known to those of us that worked on a lot of VW engines back in the day.). I have seen crankshafts develop a hairline crack that quickly develops into a full-on separation. It's been too long so I don't remember where the cracks would commonly occur, but I believe it was in between the lands for rods 3 and 4. I didn't see a huge number of these -- maybe 3 or 4 over the years -- but my memory is that these were all in non-VW (non-OEM) replacement cranks that, in those days, were made in Brazil or Mexico. From my distant memory on this, the concerns had to do with problems with the casting of the crank itself (before each rod bearing was machined during manufacture.) The better German cranks were supposedly x-rayed during final inspection. I don't know if similar procedures were in place for the Brazilian or Mexican cranks. I suspect that these days there are not very many manufacturers still even making crankshafts for these old engines, and it would not surprise me if the quality control procedures that existed back in the day aren't in place. I know for sure, when I have worked on the occasional VW engine for a friend over the past 20 years, that parts are harder to find, with far fewer selection, and some of highly dubious quality. I could imagine that the stress placed on the crank of having a large propeller subject to lateral forces of wind could easily, if there is any kind of hairline fracture or imperfection in the metal casting of the body of the crankshaft, cause the kind of failure you are describing. Back in the day, there were machine shops that specialized in VW performance parts that custom machined VW racing crankshafts from a solid block of steel. These were exquisitely balanced and worked extremely well in VW racing engines. If I were going to work with a VW engine in this application, I would probably seek out a machinist who could make the crank and cam, and find (if they still exist) racing lifters, valves, valve stems, and other key parts. Glad you are OK, and honestly, glad you are turning the page on this phase of your aviation career.

[@ctpctp]

Wouldn't a forged crank, usually made from 4140, be better than one fully cut from a billet?

[@calchip]

@@ctpctpI can pretty much guarantee that you have greater knowledge of this subject than I do. :D I honestly don't remember exactly how the custom shops that made the racing cranks made them, so they may well have been forged. I do remember that they were incredibly solid and could handle extremely high torque, unlike even the best German cranks of the day.

After noticing the similarities between a Lycoming and my Porsche 911 3.0, I thought why don't they use Porsche power plants in aviation? Turns out they did! Briefly. Too big for a Sonex obviously.

Congratulations on the safe landing. I heard you declare an emergency on 121.5 that day but didn't hear the outcome as we were on our way to the west coast and were out of range by the time you landed.

[@BadBobV65]

Former A&P here. This is the first video of yours that I've seen. There's just a couple of points that I want to make. First is you've handled your situation VERY well. Your purchase, your modifications (as far as I can tell) even your in-flight emergency was handled very well. I've seen many pilots (even some professional ones) that handled in-flight emergencies of lesser magnitude poorly, but there you are, in a high stress situation, acing it like just another test at school. Well done! Toward the end, you mention getting out of the Sonex for the reliability of something certificated... I'll tell you a little secret. Just because it's certificated don't mean it's safer. It just means that it has a government seal of approval on it, which means it has been tested and is presumably safer. I'm not sure exactly why your crankshaft suffered a catastrophic failure (perhaps it WAS because of the CF prop.. I don't have knowledge of this) and I don't know what mods were made on yours to make it an aero conversion but I would suggest trying to find the answer to that question before tossing the baby out with the wash water. Several automotive engines have been very successfully used in the aviation world following a good aero conversion. A lot of G/A guys get their nose bent out of shape because someone else is out there flying and didn't have to spend as much as they did (like it's some kind of country club that only rich elites can attend) that don't make those G/A engines safer... I've seen more carnage inside of G/A engines than I care to see, and these days, the costs of those repairs cost more than a good 2 bedroom house used to just a few short years ago. There are only a couple of automotive engines I would consider hanging in front of that firewall. My #2 choice is VW. My #1 choice is Corvair. Having said that, they can both be bad if the wrong practices/parts/conversions are used. How then can one be safe? Always do your research on practices and parts and ALWAYS be careful who you take advice from lots of well meaning people will give advice from where THEY are without knowing all the facts about where YOU are and in spite of their best intentions give advice that's bad for YOU. I wish you well and happy flying.

[@mikerubenhold1066]

Sorry you had this experience. Im surprised nobody mentioned the REAL issue. The reason that engine failed is because the front crank bearing of the VW engine IS NOT MEANT to support the weight of a prop on it. Looks like you were running a direct drive setup. The prop even when balanced sticks out pretty far from the nose of the engine block, further side loading that little bearing up front. VW engines can be built to be extremely reliable in cars AND aircraft. If you look at the nose of the crank bearing of a Lycoming or any other "certified" engine that runs a prop with direct prop drive, you will see how long and beefed up it is. VW engines nose crank bearing is very small and is made to support the cooling fan pulley only. Ive seen many setups that run the prop on the rear of the engine so that the flywheel faces forward. This bearing would do a much better job of supporting a prop. Also, you could run a reduction box that runs the prop on a stronger, upper shaft, made to support the weight, with the engine driving only a pullley on the front of the crank. Dont sell the whole plane just because of this failure. Especially after all the upgrades you have made. I understand that you might feel spooked, but at least you already know what you have serviced or changed. Buy another plane, and you are buying a whole new set of potential problems. And yes, glad you are ok. Mike

Looking at the video at 0:49, at the very least the crankshaft ended up failing. There have been crankshaft failures on Aerovee engines in the past that were initiated by the loosening of the propeller hub bolt that goes into the end of the crank, but I belive this was on an older style of crankshaft with a tapered snout. In any case, the hub loosening or failing could have put enough vibration and fatigue into the first main journal of the frank that it ended up driving the failure to that location.

[@ethanmcintosh1777]

Unfortunately the cause of failure is still unknown :( The most likely theories according to the Sonex forums are improper assembly of the crank hub, fatigue cracks, or a blockage of oil to the front bearing. This plane also had an older model crankshaft which has sense been redesigned.

[@colibri492]

After 57 years and 22,000 hours of flying military, commercial and private, my instinct in daytime VMC rightly or wrongly, is immediately to reduce power at the first hint of trouble and start looking for somewhere to make an emergency landing. I never assume that I'll be able to reach an airport and during the descent I try to analyse the problem. Vibration such as you've described can only originate in the engine, so getting down safely would be my highest priority. Nevertheless you did extremely well the way you handled things, not least because you were deliberately following a road.

[@Flash-FX]

Almost had a "propeller separation" back in the 90's. Long story, but basically bought a Great Planes 2180VW motor built for me & a buddy that went in on a experimental aircraft project. Since the propeller pitch is something that needs to be specific for the application, we decided to go with a 3 blade ground adjustable carbon prop. After a few hundred hours, while pushing it back into the hangar, the prop had a little "wiggle" to it. At first I thought that the motor mounts were softened up because of the heat of the summer day, but no...closer inspection revealed a fractured crankshaft. When I took it apart there was only about a 1/4" square left that was holding it together. The nose of the crank came off in my hand when I pried out the keyway. The "experts" told me it broke because the carbon propeller assembly had too much rotational (disk) stress and I should have been using a wood prop (lighter and able to adsorb some vibrations). I bought a new (replacement) forged Skat crankshaft, had it magnafluxed, then rebuilt the motor. It ran fine with the new wood prop but looking back, (at the time) probably should have spent the extra $$ and bought the BRAND NEW Rotax 912, that just came out. Glad that you were able to land safely!! And without any other issues... (power lines,cars,trees...ect). Be safe!!

[@dc6233]

Wow, glad you had the foresight to look ionto it instead of "it'll be fine". What's the deal with props on these? I'm aware that cranks are hard as a rock, are they too hard?, too many bolts?, are there dowel pins that align it? and just let the bolts hold it in place? Crazy to hear of one broken crank, leat alone 2, that means it's common...

[@Flash-FX]

On a VW motor (like in a beetle) the flanged end, (with dowel pins & bolts) is where the flywheel and starter ring gear go.That's the back of the motor in a aircraft conversion (firewall side). The front (where the prop goes) is the tapered end of the crankshaft with a big threaded hole inside. This taper is where a aftermarket flange is mounted to accept the propeller. There is a key that helps index the hub to the crankshaft, but the taper fit actually keeps the hub from spinning on the crankshaft end. The big bolt holds the hub on tight. In my case the fracture started (stress riser) from a corner point where the key way was machined. The crankshafts for this conversion are forged and very strong, designed for a performance automotive racing application (without any warranties). You would think that operating at much lower RPM's vs in a racing environment, this kinda thing would last forever. But not with the added propeller loading. @@dc6233

So the front fell off. This isn’t very typical, I’d like to make that point.

[@danceswithclouds]

I wondered how such a young man handled an engine failure and highway landing so calmly, then I heard you are a flight instructor. Good for you. But I chuckled when your plan is to move to a certified engine to avoid problems. My first in flight engine failure was with a Lycoming 0-320 with only 320 hrs smoh. Tappets were polished and reused during overhaul, a practice thats no longer permitted. With no warning the cam lobes went and I could not maintain altitude over a lake. Barely made it to a tiny airport. Second failure was due to horrible A&P who plumbed a drain port from the ED pump to a pressure port on the fuel servo. Engine suddenly quit and I was on glide on my very first flight in that airplane. Barely made an airport. Thats two failures with certified engines. I'm sure your experience has taught you something very valuable- that you remain cool under pressure! Excellent.

[@galehess6676]

I haven't landed any dead planes but see this common thread in failed engines: A rebuild. Similarly to Tesla autos commonly having replacement motors/batteries being sold just prior to the end of warranty, planes tend to crash just after a rebuild. Avoid Teslas, and have someone else put on at least 50 hours post rebuild, 300 is better from what I've gathered.

[@cjsaunders06]

Man this was absolutely incredible. The landing, the time and labor you spent making an experimental craft IFR capable. It is truly impressive. I love it. This is the first video of yours that I have seen, and I am already sad honestly that you are moving on from it. It has so much potential to be something REALLY cool. Best of luck on your future adventures!

🤣🤣🤣 excellent

[@JohnConnorTM]

DON'T GIVE UP! fix the engine, take it apart and put it back together again, you'll find the parts that need replacing, then take the whole plane apart, do a major inspection. After that, it will be safe flying it again. This is the lesson to learn, those who succeed, didn't succeed the first time the tried.

id just get a modern rotax engine for it. it seems the rotax 912 is super common and standard now

He concluded the video by said that flying at night/ifr with an uncertified engine would impose a risk most pilots deem too high, and that finding that out was eye opening. That was the lesson.

Bro, you are cranking out some awesome videos. Stay safe and have fun!

[@wesleybremer1275]

"you cant park there" lol

[@wzpu3283]

I will bet that bro's major in college is not Mechanical Engineering or similar, because if it was, I would not expect him to say that the crankshaft failure was "unrelated" to the vapor lock issue, due to the fact that the crankshaft (very likely) failed due to fatigue, which the lean combustion mixtures caused by intermittent vapor lock in the fuel lines would have significantly contributed to, by causing abnormal combustion such as preignition and knock that likely applied counter-acting forces to it, especially since he indicated that the issue occurred for a significant amount of time before it was mitigated. Anyway, I'm very glad he's OK and I have much respect for him and his efforts, ambition, and wherewithal.

[@strangersound]

I'm no expert, but I think your probably on the right track. The pictures definitely looked like a fatigue failure and lean combustion can wreak havoc on an engine. I found an FAA pdf from 2019 on the dangers of pre-ignition and detonation and the extreme stresses it can put on an engine. "Both pre-ignition and detonation put tremendous mechanical stress on the engine," source: faasafety.gov/files/notices/2019/Jul/Preignition.pdf

[@rokoala2636]

I agree, the engine was assumed reliable after it was run in a way that basically beat the crap out of it. It will be interesting to see what the report says.

[@ieuanhunt552]

I'm no engineer but it stands to reason that a misfiring engine could impart some forces into the crankshaft that it was not rated for.

[@TurdFurgeson275]

You're a badass for handling that landing like that. Glad you're okay. It's incredible you didn't hurt anything/anyone at all. Really skillful.

[@donpugh8099]

I went to school to become an Aviation Mechanic did three years learned to fly first then hands on Maintenance but I never finished that was 30 years ago everyone said no don't do it it's not worth it flying is dangerous and I listened and threw it all away. I wished I would've completed it. That's a nice plane and things happen.You accomplished alot .SUCCESSFULLY and on your own. Don't give up on your dream Buddy no matter what others say .Get a parachute for it..They aren't real expensive. Finish it. VW beetle engines are used all the time but you can go different routes...Proud of you my friend

[@linuxguy1199]

Can we get an engine failure analysis? Crankshafts don't just break and from the look of the failure it looks like a fatigue failure, something that again should never happen to a crankshaft since they are typically made from a hardened steel that due to the thickness and hardening has an infinite fatigue life, especially in an airplane where the forces are all in tension, essentially trying to pull the crankshaft out of the engine, again hardened steel is extraordinarily strong in tension and should've easily handled any load applied. The crankshaft had to have been damaged at some point, potentially something smacking the propeller causing a slight bend in the shaft which led to a fatigue crack that expanded over time, causing the vibrations and eventual failure. Another person (@calchip) here mentioned the potential of a casting failure specifically in VM cranks in that engine and that could certainly cause it.

[@angelapolinar5343]

Yes, however you have to notice that this is not an engine built for aircraft but rather a general purpose engine that works in an aircraft, for a while. But has the crankshaft is not actually built to support a prop, much less one that will be freespinning and pulling a large weight forward. Most likely tension went over yield strength and developed a hairline crack. Then all you needed was a long flight to exacerbate that crack.

[@EvanTuer]

Crankshafts do just break though. I've had two engines fail in this way - in cars! Losing the crankshaft pulley with the end of the crank, you can drive on for a minute or two but without charging or more importantly cooling. Sump oil also pours out of the hole. The failure mode is fatigue or fretting around the front bearing. Those were high mileage situations but I would consider it foolish to add the vibration and gyroscopic effects to a shaft and bearing arrangement that can fail with just a small pulley and V-belt on it. It's just not designed for a prop. Glad Ethan got away with it!

[@linuxguy1199]

@@EvanTuer I've personally never seen it but I can understand it happening with a v-belt instead, with a v-belt or pulley the crankshaft is always being cycled from being in tension to being in compression, which is a lot of fatigue load. For a propeller the crankshaft should always be in tension, and steel is strongest in tension. I can understand the bearing or seal failing due to too much tension but that's about it. I don't see a reason that the engine couldn't be able to handle a propeller, unless either the propeller was extremely out of balance or the crankshaft had some sort of damage.

Honestly I learned so much from this and it is so awesome to see how much fun you had and see your still here with us even despite the engine failure. I wonder if the engine ran too lean and fail subsequently. With car engines I know from experience too lean is way worse than too rich and you can cause engine failure.

[@whoever6458]

First of all, I'm glad you're okay! Great landing! It's too bad about feeling like you should fly a different plane. Money has been the main barrier to my entrance into the world of becoming a pilot. I've been flying simulators since the late 80s and taught myself how to fly by trial and error from a program I discovered on the computer my dad brought home because of his job (dad was a computer guy for a military contractor working closely with the Air Force). I only ever got to fly a real plane once because a friend of mine took me and some other friends flying one day. It was a blast! I'm always one of these people whose head is practically glued to the window in commercial flights because I love seeing things from a higher vantage point like that. Never could afford even basic ground training though and I was too cowardly to join the military and see if they would train me to fly. Now it will probably never happen so I'm glad you got to experience it and I wish that more of us could because it's outstanding to fly a plane! Seems like mostly what you need is a new prop, perhaps a new engine, and perhaps some more redundancies built into your plane. You're alive to have learned from this and so you might as well put that insight into practice if you can. I can see why you might feel some kind of way after having a mishap in that plane and I can totally understand that. I crashed a motorcycle and, before I knew if it was totaled for sure, I will honestly say that I kind of feared that they'd repair it and give it back to me because I felt afraid to ride it again. I don't know if I would be afraid to ride any motorcycle because I haven't tried. I damn near lost my life in that accident and I did lose all the ligaments in one arm, but only because I was lucky enough to be able to scramble to the side a little bit from the trajectory of my motorcycle. It ended up between the wheel wells of a truck and I scrambled my way far enough not to hit the truck at all. I'm just not sure I would have been able to get back on that specific motorcycle but I feel like it might have been different on a different one. If I had had the money, I might have gotten another one but another thing I realized that is completely separate from the accident is that it's a pain in the ass to get stuff home from the store on a motorcycle and it was very dangerous to ride in the summer because it gets so hot here. In fact, I might have saved myself some road rash if I had worn my jacket that day but I considered the risk of heat stroke to be more immediately dangerous and I will honestly say that that decision was correct but I just happened to get unlucky on that particular day when I would have rendered my mind less effective on thousands of other similar days had I worn my jacket in the heat.

[@outcry27]

Speaking as a CFI, I'm absolutely in awe of the ADM and professional attitude you display in this breakdown. I can only imagine how disappointed and frustrated this outcome must have left you, but i hope you take some well-earned pride in how you've handled all of this.

[@dustcommander100]

So glad you were able and skilled enough to land safely! When I saw the crankshaft extension behind the prop, I had a red flag pop up. Although not an expert, I would suggest that the period of rough running make have stressed the crankshaft and started the process of failure. Neither here, nor there, but just my opinion. I used to hear about Subaru engines being used on homebuilt aircraft, but seldom hear of that anymore. What I do hear is that modern Subaru cars seem to have a lot of problems with head gasket failure. Of course, one might consider this a sign that only older engines (both VW and Subaru) are to be considered for aircraft use. I think you really cut to the truth regarding safety and legality. Not obvious until pointed out by a perceptive and wise individual. You will go far, young man!

[@xetothex]
