Stig Education (Bird strikes)

[@Pupda]

Speaking of paperwork - from the cockpit we have four notifications that we have to make: 1) ATC -- for (hopefully) obvious reasons; I had a bird strike just a week ago, and we would want to let the aircraft that were following us into the field to know. The tower keeps track as well, because they also have to file reports. 2) Company operations - they need to know as well - among other issues the airplane will be grounded for some time for the inspections Stig mentioned. 3) Company maintenance - to perform those inspections Stig was talking about and to eventually return the aircraft to service. My last bird strike occurred at night at an outstation where we don't have our own maintenance staff, so in that case we call our Maintenance Operations Center down in Texas and they in turn call a local maintenance company to come out and perform these inspections. By the way those local maintenance companies are under contract to us (we're not doing this "on the fly") and have been trained in our procedures but mostly on our paperwork (they already know how to fix planes). 4) Fill out the appropriate FAA forms for having had a bird strike - the government keeps a database of all bird and wildlife strikes. This is by far the most annoying step, as you can imagine; there's never anything simple about government paperwork... Bird strikes aren't fun, especially for the bird... True story - Stig mentioned that maintenance has to find the remains of the bird, when possible; the airport operations people have the same mandate. When I was a young first officer we had a bird strike in LaGuardia during takeoff - the bird basically hit the captain's windshield dead center and bounced off intact. We aborted the takeoff and returned to the gate for the maintenance inspections. While we were at the gate the Port Authority drove up in a pickup truck; one of the guys hopped out and pulled the carcass of a female seagull out of a bag and held it up by the neck for us to see. Also, for the passengers to see...that didn't really go over so well. (As Stig mentioned, we have to try and account for all of the bird if we can - that determines where and what maintenance has to inspet, so the Port Authority guys were doing the right thing to bring the carcass over, but they were supposed to show it to the maintenance team, not us.)

[@GhostSniper67]

Thank you Captain for the information. Nothing government related is easy. If you get one thing wrong you usually have to do it over.

[@vv-cv6ud]

Great information thanks

[@StigAviation]

As always you never disappoint with the knowledge. Thank you Captain. Pinning this one. Incredible story as well

[@YojimboZantetsuken]

Far too true, had to do this myself a couple times in my tenure with a regional carrier. We'd bag up what we found, fill out some wildlife department paperwork, and then pass it on to airport operations.

[@MyTopTalent]

@@YojimboZantetsuken lucky you that the government didn’t ask you to mail the carcass to it’s office 🤪

[@TimAyro]

Pilot here. If a bird goes through the engine, even if your engine doesn't fail, you will smell it. That's another way we'll know.

[@hayleyxyz]

Bleed air right?

[@jakint0sh]

​@@hayleyxyz Yeah, the air that the packs use is taken from the engine bleed, so if there's a bunch of liquified bird all over the fan blades I'd imagine you'd wind up smelling it in the cabin (not a pilot, just a nerd).

[@BPantherPink]

​@@hayleyxyz BLOOD air 😊

[@waymanprice478]

good one. 👍🏻

[@InvisibleSquids]

Mmmm, love me the smell of fresh air kill

[@wizardmix]

I've encountered a few birdstrikes out on the ramp included a severe one that went into the intake and took #1 on an E175 out of commission. I'll never forget the sound it made coming back in. I'm always out on the lookout for birdstrikes on all my walk arounds and searches, especially on the STARs, it's something critical to the morning.

[@StigAviation]

The smell is what always gets me. Especially if the engine ingested it

[@rubbler3]

Stig, these shorter types of videos are awesome. You could build a nice catalog of scenarios over time utilizing this presentation. Keep up the good work.

[@StigAviation]

I’ll definitely organize it better in the future videos. I’m glad you enjoyed the shorter segment

[@Guy_Interesting1996]

​@@StigAviation We were waiting for this type of information! Am glad you saw the demand and provided for it.

[@walla1je]

This was a fantastic video. Never would have thought that they would send the remains to The Smithsonian. That blew my mind a little. Been an av geek my whole life, but, ironically, I was afraid of flying. Videos like this helped me get over that fear and now I fly every chance I get.

[@StigAviation]

I am glad to hear it helped you get over your fear, thank you so much for watching and learning.

[@SimonBillingham-zq4oy]

I have changed several JT9D fan blades after ingestion of birds, seagulls and Galahs (Australian native parrot), the intake always smelt terrible. On 747’s in general if engineering found a bird strike the flight crew knew nothing about it and if they reported birds we found nothing. Keep in mind most bird strikes take place on approach and takeoff where the 747 has a high angle of attack therefore the crews horizontal position is near the top of the fin so observed birds are passing near the upper half of the fin. Also found marks and bits of birds in various locations, in the leading edge of a foreflap , landing gear, fuselage, inlet cowls etc, you will know all the locations. Well explained in the video.

[@StigAviation]

Once you smell it you never forget it. It’s quite horrible 😅.

[@Brotatochip702]

We had a bird strike almost break right through the raydome on the nose like 2 months back. Started to delam and crack on the inside. Of course the exterior was dented and bloodied. Then a couple weeks ago had ingestion on our #1. When we were borescoping, there was feathers and blood and what not on some of the variable guide vanes… no damage. Luckily. QC deemed it good. Just needed an engine wash. Most of the birds did go through the bypass like you mentioned. It was my first time going through the whole ingestion inspection process. Very time consuming, fun and very educational.

[@StigAviation]

How about that smell 😅

[@haowenyang2007]

YES!!!! STIG!!!! WHAT A START TO A WEEKEND!🎉🎉🎉🎉🎉

Hi Stig, I aspire to be a aircraft maintenance engineer when Im older. Even though I'm only doing a Certificate 2 in aircraft maintenance at this current moment. Your informative videos help me grasp what my future will hopefully be like (even if its directed to a apprentice level) Many thanks Stig and keep up the good work.

[@StigAviation]

Thank you, and good luck on your journey. The world needs more good mechanics like you.

[@shyammohabir8283]

Valuable knowledge for pilots - as a young pilot many years ago . I was thinking out aloud why not put a mesh in front of the engine blades - but didn't realize it will adversely impact engine performance and if it the mesh gets ingested by the engine .. Thanks for sharing..

[@StigAviation]

Glad you enjoyed it and thank you for watching

[@andyny29]

FYI- At 2:07 the Peregrine Falcon can fly at up to an estimated 200mph in a dive while chasing prey. The Pigeon at 1:00 is probably the Falcon’s favorite target.

[@StigAviation]

Falcon is such a beautiful bird.

I do have a tool video but I’ll do another one in the future. I wish you all the best in school and for now you don’t have to worry about tools as much. Just focus on the studies.

[@gunarzoretic]

@ Thank you sir!

[@GlutenEruption]

Me and my PPL instructor went through a flock on landing one time - it seriously looked like something out of a horror movie. The windscreen and engine cowling was just COVERED. Thankfully we were already practically in the flare and regardless it didn't cause any damage (low speed was a help but the prop was umm... extremely effective at making sure there were no major pieces left to damage anything... 🤢) but that was a heart stopping moment seeing them flying into view and watching in slow motion knowing they were going to hit and there was nothing we could do. Not one I'll ever forget.

[@StigAviation]

I can imagine the adrenaline that’s going through you when you see something like that coming at you. But I’m glad you guys made it safely

[@puerco911]

Wow incredibly informative, didn't have a clue so much goes on after a strike! Kudos for calling out for kids being around!

[@kdawg_gde]

Very good video. I forgot that bird strikes were a thing and that it can be a range of severity. I always assumed bird strike meant “engine failure”, but I was wrong and that’s ok, still learning 😎. Stig never disappoints with his uploads

[@StigAviation]

Glad you enjoyed it and learned something new 🤙

[@Gar-sq9pg]

I agree about the fence and the challenges with that. But the F/A-18’s have a fence in the intakes and I have seen bird strikes hitting them too. They’re quite durable as well as with the rest of the airframe and they’re guide vanes so it still directs airflow.

[@StigAviation]

I didn’t know about that feature on the F18. Thank you for teaching me something new

[@philjones3550]

Excellent as usual.

[@StigAviation]

Thank you! Cheers!

[@thisisus.504]

Wow wow wow. Who knew the background work to a bird strike!! Amazing.

[@StigAviation]

It’s a lot of work, so when it does happen that’s why aircraft can take a delay. We are trying to make sure it’s safe to fly again.

[@FU2Max]

Hello Stig. I just love your channel, and I look forward to your videos. I have a question. Do aircraft ever get cleaned? - all that grease on the leading edge etc. Thanks Stig o/

Hi Stig. Loved the different content though I think I will skip lunch now 🥴Could you perhaps do a piece on how you sign in and out tools when working on engines following the news of the A380 flying for a month with a tool left in it and found by the great teams at LAX 😉. Thank you as always for the great content you make.

[@StigAviation]

Thank you so much, I appreciate that

[@747rotate]

Hello again Stig! Another stellar video! Got a little question for you. I know of a first officer that's only been working 4 months at United and the other day they promoted him to Captain with no prior experience at any other airline. How is that even possible because as you know it usually takes several years and boo-coo flight time hours to make Captain. Just blows my mind. Have you ever heard of such a thing?

[@StigAviation]

I honestly don’t know how that FO got promoted so fast. They must be in dire need of pilots if that’s the case. Also I’m not well versed in how pilots move up in rank. This question is best answered by another pilot probably.

[@747rotate]

@StigAviation thanks so much Stig. Yeah with my father and I experience in aviation (65 years total) we've never heard of such a thing. Personally I think that's pushing the envelope a bit. I did find this gentleman's channel by accident who's a FO with American that explains about pilots salaries amongst other things and is very good at it. I asked him the same question but haven't heard back yet. Here's the link if you're interested. youtube.com/@flywithgarrett?si=Y9t6d78JicJaNL-u

[@bobszoldra3515]

I had to clean my fair share of bird remains out of landing lights and landing gear. In the winter we always used to have a few snowy owls that used to love to perch on top of the tails of our L1011s when they were parked out in the hold areas.

[@StigAviation]

Worst ones is when aircraft hit the ground critters or animals running around the runways. Makes a big mess as well.

[@bobszoldra3515]

We had a deer run out on the runway. Pretty messy. The falconer used to trap a lot of small animals. Best thing I ever saw was a B727 that brought a tree with it. Some in the wheel well and the rest in the flaps. Almost touched down a mile or so short of the runway.

[@tomt8692]

I used to be be RFFS at BFS. Part of our duty was bird scaring duties. Lapwings were our biggest incidents. Really stupid bird lol. Saw a few videos of ground handlers going through engines. Nasty

[@StigAviation]

The smell is even worse 😅

[@MarioBradshaw-cy9kq]

Like your work wish i had that job

[@StigAviation]

Thanks for watching. It’s a pretty cool job for sure.

[@tronjet66]

Very interesting, I didn't know it was the Smithsonian that did the ID

[@StigAviation]

What I found out about that when dealing with my first bird strike, I was just as surprised.

[@jneill]

Love the pigeon opening strong by just sauntering around like pigeons do :). I know of one airport that purchased this rather elaborate sound gun technology that went off at intermittent intervals to get rid of corvids. Corvids are famously intelligent. Took them less than a day to determine that it wasn't actually harming them and started using the canons as perches. Sound went off and they move off a little bit before settling back in less than 5 mins later. More and more airports has enlisted the help by biologists and ecologists and even local birding groups. One airport was having issues with snowy owls (they think the open grounds surrounding an airport is tundra). A local ornithology guy sat around the airport for a week until he'd caught the last of 4 snowy owls and had them released elsewhere away from any airport grounds.

[@StigAviation]

It’s a difficult task to get birds away from the airport, but nature will always find a way. After all, they were here first

A WestJet flight leaving Toronto recently had a birdstrike on the Pilot window which shattered it to opaque. They had to come back for a landing and got towed in due to no visibility for taxiing. This strike hit right at the top of the window such that it broke the seal and affected pressurization.

[@seagullsbtn]

Only time it's happened to me was in a Cessna 310, when a bird got chopped by the prop on #1 engine while crossing the English Channel.

[@StigAviation]

I thought it was Flair Airlines. yes I did read about that one.

[@StigAviation]

Glad you made it down safely.

[@LtKernelPanic]

There was a bird strike in Toronto that actually penetrated the captain's windscreen causing minor injuries due to flying glass last week. The bird in question was a Canada Goose. There's a picture on The Aviation Herald that's not for the squeamish.

[@StigAviation]

I saw it. And that’s a huge bird. The aircraft handled it pretty well.

[@Glegh]

Ooo new series? Also, what do you think about that Flair (?) Captain who was injured by window shards after a bird strike a few days ago?

[@StigAviation]

I’m reading about it as I type, looks like they hit a Flock of geese. Those are big and heavy birds. So the damage is understandable. My thoughts on this is that the aircraft kept flying and the other pilot took over. Glad they made it back safely. Goes to show how strong aircraft are and why you always need two pilots on board.

[@oliver_klozoff]

Cool to see your process. Bird strikes also can take down semi trucks believe it or not. Had a smaller one crash through the grating in front of the truck and knock a hole in the intercooler that put me into limp mode. Not as drastic as an aircraft, but i did take a turkey to the windshield that shattered it once. Ngl i about needed a change of underwear from that one.

[@StigAviation]

Well the good news is that the semi can park on the side of the road, for the airplane, clouds are not the option to park on 😅

[@zacheryziegert7960]

Love the video Stig. What’s the frequency of bird strike at LAX? It feels like we are having planes come in with bird strikes 2 or 3 times a week where I work. Become very used to opening up AMM 05-51-18 😂. Thankfully no damage yet🤞

[@StigAviation]

To be honest with you, it’s a bit unpredictable with the bird. Best I can say is migration season seems to be most time we have them so frequently. From the last month I think we had like 3 of them so far. But like you said, luckily no damage occurred.

[@TheSoggynacho]

Interesting video sir, I wouldn't want to have to pull out what remains of a bird though. Can you keep one of the blades from an engine if you have to replace it for any reason? Be a cool thing to have.

[@StigAviation]

Unfortunately I can’t keep a damaged blade. Those get sent back to the vendor to analyze for repair or recycling. Although you can buy blades online from decommissioned engines.

[@GiorgiBranquinho]

Hello Stig, how are you? I really enjoyed the video! I wish you success! I have a question: why are most of the electrical wires in aircraft white or purple? Do you find it challenging to work alternately with Airbus and Boeing? Do the technical aspects of these manufacturers differ a lot? Thank you!👍✈️

[@StigAviation]

Electrical wires, the standard ones are usually all white, anything that’s purple is usually fiber optics, anything that’s yellow is usually ethernet.

[@GiorgiBranquinho]

@StigAviation Thank you, Stig, for your response. I’ve always wondered about this, because when I watch your videos, I see all the electrical bays with white and sometimes purple wires, and I always asked myself if it was a standard.

I remember my bird stike in a 55c. It sounded like a bomb going off in the nose. When we got home, we discovered that the bird slid back along the nose and was sliced open by the AOA vane, and the rest of it was stuck to the paint. Fortunately, the engines are mounted up high on the empennage, and the bird parts passed under the right enigine.

[@StigAviation]

That unmistakable THUD when it hits. I’m glad you made it down safely

[@flashygator]

Great video as always. Question about the bad idea of putting fencing in front of the engine intake. Is it true that putting a fence or some type of guard to prevent bird ingestion can increase the chances of a compressor stall due to how it affects the air flow?

[@jakint0sh]

Well I guess that would be possible, but the main point is that all sorts of preventative devices have been considered over the years, but not put into use because of various concerns. You'd think that we would have had this figured out a while ago, but I guess it's not such an easy problem to solve.

[@StigAviation]

It definitely could restrict airflow and can cause that compressor stall as well. Especially on these high bypass turbo fan engines. It could work on smaller engines. I just learned that the F18 has such fences

[@thereissomecoolstuff]

Stig just flew Seattle to Boston on Alaska. No internet. They warn you by text. Can you explain how that system works and how you trouble shoot it. Have a great week.

[@StigAviation]

It happens time to time where the WiFi antenna or the IFE (in flight entertainment) is malfunctioning. It’s a deferrable item. Sometimes it does glitch and a simple reset (turn off and on) does the trick. Other times it requires a computer box change and in worst case scenario to replace the WiFi antenna itself (the big dome shaped thing on top of the aircraft).

[@thereissomecoolstuff]

@ Thanks Stig. It was a 5 hr flight and I didn’t bring a book. Man you get spoiled nowadays. That antenna swap has to be a monster job.

[@josetellez1803]

@ it wasn’t. Just a shallow dent. Within limitations so it flew. Coming in next week for the repair. On a Honda jet so it’ll be interesting to see how much work it’ll take

[@ChrisCokeRobinson]

Sometimes these ingested birds can be so small that there's barely any visual evidence, but there's a mild distinct smell around the intake that sets off alarm bells and makes one think "there might've been a bird ingestion. let me investigate more thoroughly". Sometimes there's nothing, maybe confused it with the smell of squashed bugs or burning oil fumes.. But many times one ends up finding small traces of blood and one or two feathers, maybe on the IGVs or the first set of rotors of LP compressor. Sometimes along with a trained eye, you need a trained nose as well... and then a borescope inspection..lol

[@StigAviation]

@@ChrisCokeRobinson you’re absolutely right on that. The smell is very distinct.

[@YojimboZantetsuken]

In my experience at smaller airports, they use a mix of horns/fireworks/shotgun blanks to scare off birds from a roving airport ops truck. At least once per day, if not several. You never know when it happens, so myself and others always end up ducking sometimes when we hear the blasts nearby. 😂😅

Hey man! What happened to the "How Much Does It Cost?" segments? 😊

[@StigAviation]

Some people got upset at those so I had to stop doing them.

[@collectorguy3919]

Bird, bug, or bat? Aircraft must encounter bats, but they're quite small. So far, no aircraft has ever encountered Batman.

[@StigAviation]

Never seen a bat, but I’m sure it happens at certain locations where airplanes fly into. My guess would be probably in South America

[@robertkalinic335]

Soviet fighters had the retractable protection for takeoff and landing against debree, seeing the consequences for airliner and considering the harsh conditions of wartime airfields and improvised strips it made sense.

[@StigAviation]

That’s very interesting. I’ll have to read up on that

[@JimmyfromtheNorth01]

I just cleaned a bird up 2 weeks ago. Bounced off the #2 and hit the inboard k-flap.

[@StigAviation]

Any significant damage?

[@JimmyfromtheNorth01]

No they were tiny no damage noted.

[@kevinjones2772]

OnI of my friends who has had their license for years has had multiple bird strikes in his light aircraft. Each time he has one he paint it on his plane similar to how the us air force paints kills onto their plane

4:23 hydraulic line 2nd from the right on the gear was leaking from the coupling.

[@StigAviation]

There was no leak my friend. That was just water from the condensation of the strut.

[@vhwft]

@ shit must have been real humid to have that much condensation. They were steady drops.

[@gmotors5917]

Can you please how an aircraft is sealed to maintain pressure?

[@StigAviation]

I have talked about pressurization on aircraft in older videos. But to simply put most doors are plug style and aircraft uses the air conditioning system to pressurize the vessel and the outflow valve to regulate the pressure.

[@MarioBradshaw-cy9kq]

I see a380 in your video all the time but not closeup they either flying away can you get close to them at all i want to see how big they really are

[@StigAviation]

@@MarioBradshaw-cy9kq I don’t work on them. That’s why I don’t have any close ups.

[@mikehanks1399]

I think I have a fix for ingesting birds into the engine. Put those clam shell type thrust reverser doors onto the front of the engine for use during takeoff. They would be mounted just like the ones on the back of the engine, only they would be facing backwards, forming a wedge shape.There would be enough of a gap for the engine to get air but the any bird hitting the intake area would be directed over or under the engine. The knife edge shape of the flap would be aerodynamic, especially during the relative slow speeds right after takeoff. The flaps could be retracted after initial climb out.

[@collectorguy3919]

Anything that restricts airflow or creates risk of debris being ingested would be a no go. Aircraft performance is crucial for safety, so airflow matters. A goose or other heavy bird could break pieces off anything meant to protect the engine. Metal is more damaging than flesh.

[@mikehanks1399]

A goose or heave bird being ingested into the engine can, and has, brought an airliner (and other planes) down. Perhaps my goofy idea would be difficult to implement and would carry some risks. But I think a device like that could be engineered to work safely. Perhaps the entire intake could be made to pivot several degrees so a bird could not be sucked directly into the engine. Time for some out of the box thinking.

[@StigAviation]

That’s very interesting, it’s a clever idea but it would take a lot of engineering to make that. Also you’re now adding more moving parts and extra systems and more weight to the aircraft. You have to take those things into consideration. But still a very interesting concept you presented. 👍

[@collectorguy3919]

@@mikehanks1399 By all means, keep thinking differently. Creativity and persistence are valuable. Testing your ideas is really important too, because it's also possible to create unexpected new problems. Problems are solvable, and sometimes you make progress by creating better problems. Maybe a hard blast of compressed air, triggered by an electronic eye, could deflect a bird away from the engine and the rest of the aircraft too. (The food industry uses puffs of air to reject burnt potato chips or cereal pieces that are overdone.)

We made the Saturn 5 and the space shuttle.

[@njjeff201]

Stig, was that a Ladybug bird? Very rare!

[@StigAviation]

Yup. Cute little thing

[@hiteshkadu6751]

hey stig, what if the bird strike occured on flaps when they were fully deployed, and after landing they get retracted. So how would you or anyone else get to know about that?

[@StigAviation]

You’d still see the blood and feathers. Or some significant damage to the flap if the bird was a large one.

[@Mike-b3v]

Sadly. My buddy was in his 183 yesterday and I go to pick him up. He lands. As he’s pulling into hanger I see a bird beak stuck into edge of wing. There’s a very big dead bird somewhere right now. I’m not a bird guy but that beak was big.

[@StigAviation]

Important part that he landed safely. Hopefully it’s not too much damage

[@njjeff201]

Just saw on the news that a plane was shot coming into Haiti. They said it had 4 trips without being discovered. All flights now cancelled. Think it was American’s unit.

[@StigAviation]

Ya saw that too. Crazy right

[@renefuller9241]

Question: how do you determine if there is any structural damage to the skin the bird bounced off of?

[@StigAviation]

A few ways of doing that. One is the basic visual inspection. If there’s a dent or cracking is evidence of damage. A tap test on the impacted area to determine if there is delaminated surface. There’s other NDT (non destructive testing) procedures to use if we find damage.

[@renefuller9241]

@@StigAviation Tap test... I didn't think of that! Good to find delamination and such.

During aircraft certification they fire 3 pound birds at 150 knots to demonstrate viability. Every class I’ve been to mentions this, then some class clown invariably says they also fire 150 pound birds at 3 knots😂

[@StigAviation]

150 pound bird would completely destroy anything on an airplane 🤣

[@MyTopTalent]

Stig, why isn’t there an anti-bird horn on the plane’s nose pilots will use as a last-minute resort to deter birds / flocks heading for the plane? With a few sound options e.g. gunshots, enemy birds etc. Could Sully have used it in the few seconds he had pre-collision?

[@StigAviation]

That is an interesting idea for aircraft systems to prevent bird strikes. But I don’t know how well it would work when a jet if flying that fast.

[@MyTopTalent]

@@StigAviation not an engineer, I’d expect sound from the plane forward would travel at 1 Mach, faster than the 0.85 Mach cruising speed
