CATASTROPHIC ENGINE FAILURE in the middle of nowhere - The Story 

Trent Palmer I am a aircraft maintenance engineer from Holland. The failure could have something to do with beaching. A little crack not smaller than a hear getting bigger over time. Check with your N.D.T. specialist if this could have bin the case. Have fun flying!!!!

Trent Palmer music? Artist? Song names?

Come look at D-Motor while you are in Oshkosh this year.

At least you didn't have to replace fuel injectors on a ww2 B17 flying fortress and At least you can load your plane on a trailer just the wings barely fit on a semi truck trailer

Can your install forged connecting rods in near future? Maybe have heads rebuilt also. Get all the internal seals and metal parts upgraded to higher quality metals

i just made that comment.. then i read the comments and see you did it 7 months ago -_-

Also the pilots posterior tends to grab the seat cushion with great force

Unoriginal

It also keeps the rain off the windshield.

An oldie but a goodie.

LOL

Bears aren’t that tough. I usually go poop in my pants immediately, like a survival instinct. The bears usually smell it and run away from me. Its saved me a few times. (jk)

Or go with friend you can outrun!

@@boatrvme8478 yepper, the wife loves to go on hikes.

Kurt Buck wouldn't that be something? Hahahaha

So much freedom in America

@@carsandstuff365 most countries require a fishing license, and of all the things that you can have licensed, licensing for wildlife conservation seems pretty important to me.

D W paying money to a corporation for the privilege makes it important does it ? How does that change anything. Literally paying money to someone and they say ok you can do that now lol .. brain washed much

Nelson Ashbrook lol: cried most when the bill arrived!!

That made me chuckle

LOLLLL

Cool 😎

Thanks man!! 🙏🏻 and welcome to the channel!

The good ol' classic

🤓 I cant help it, I come from the short form video world where anything beyond 3-5minutes is too long... haha

long videos the new wave

Apologize if it's 3-5 minutes lol

Too long? Never! It's great to hang out with you. Longer video just gives more time for coffee.

well, structurally this is effectively a compilation of a number of short videos, a. Engine failure - reaction analysis (how I got down) b. getting myself, the plane, out of wherever i was *(recovery operation) c. repair/test flying the new setup d. incident analysis (what went wrong) ...all very beautifully compiled into one video....

@kryptoday well, not many. The last of the surviving pilots from the Doolittle raid just died at over 100. If they weren't bold there's no such thing 😀.

Brian D Yeah, those engineers built it the way they did for a reason. Smart move.

Yes exactly. Performance and reliability are two opposite sides of the spectrum ...

I start everyday with an "awe F**k"

@@ninejets 😂

ninejets 😐

@@ninejets haha lol

Now most important of all - - Did Trent catch a FISH?

no didn't have a fishing license.

The Fumbler no lol it was a snapped piece

Nvm ur right lol

Underrated comment

thats the "High Performance Mode" option

Especially the CEO of Kitfox Aircraft!!! That's called CUSTOMER SERVICE. Can't wait to order mine.

It’s because it’s Idaho. We do that around here

niceguy217 well said. I agree on all points.

An Inreach satellite communicator can provide two-way text communication over the satellite telephone network and the cost of the unit and subscription plans are a fraction of what a satellite phone would cost. I believe that Spot offers a two-way text option on some of the new models as well. I don't know if these are an option in Australia however.

Bass Player really hit the nail on the head here. Great comment.

THINK: What is the max pressure when the fuel ignites and compare that to 12 psi vacuum. Vacuum is not what breaks the rod.

Apples to oranges. Completely different function. 25 inches of mercury will probably crush a full size car to the size of a mini-cooper...

@Paul Ohlstein: During combustion cycle, the pressure inside cylinder is greater than in crank case, so the piston is pushed towards the crankshaft. The connecting rod is under compression at this point (getting pushed together). For most materials, the limit of compressive strength is buckling (like a connecting rod getting bent out of shape due to too much torque load). During intake cycle, the piston is drawing air into the cylinder, so the connecting rod is under tension (getting stretched apart). Compressive strength and tensile strength are different types of strength, and a part or material that can tolerate tremendous compression may be much less durable under tension - and vice versa. Damage or manufacturing defects can also affect a part's strength differently for different types of stress. If you think about something like a connecting rod, if it has a manufacturing defect or a hairline crack, it's going to be significantly less durable under tension or shear stress, but might perform just fine under compression. How much tension is generated depends on the pressure differential between the cylinder and the crankshaft (which is typically under ambient pressure), and the surface area of the piston. So if the manifold vacuum gauge is showing 25 inHg vacuum (pressure differential) at sea level and the bore diameter is 79.5 mm, then the force on the piston (and tension on the conrod) would be about 535 Newtons. This is like a hanging weight of about 54.6 kg, or 120 lbs. Normally, not a problem for a connective rod by any means, but if the bore diameter is increased while the manifold vacuum remains the same, then the force on the connecting rod increases as well. I don't know what the big bore kit's diameter is on this engine, but if the bore is increased to 84 mm, then with the same vacuum (25 inHg), the force already increases to 597 Newtons, equivalent to 61 kg or 134 lb weight. The key thing is that this is a cyclic stress, not a constant load, which is what causes metal to fatigue. In fact, on the picture at 19:20 timestamp, you can see that some parts of the broken conrod's cross-section are smooth, almost shiny, while one small area is jagged and cracked. The smooth area is a fatigue crack that developed during a long time, forming an almost flat "cut" across the part. The jagged area is where the final failure happened, when the metal that was still holding the part together was deformed and broken. There could have been a defect in the part, but more likely it had just developed the fatigue crack starting from a minor "notch" on its surface and it grew from there.

I'm done here, I feel I need a tetanus shot...

Foardhook What's wrong with haggling? I don't completely bend someone over, but negotiating is not mean or inconsiderate.

Pilot Nikolas as a former member of law enforcement/from/emergency management, you know the ones who get called to find you, an excellent suggestion. Just a note stuck on the joystick/yoke or someplace identifying yourself, clothing description, what you saw that makes you think it could help you, and direction you are going to be walking. I would suggest a carryon bag with either a high fluorescent green or orange vest you can put on. Also a small first aid kit, definitely something in it to stop heavy bleeding like an Israel kit, also other bandages and splint material, even some type of food like granola bars or something with high calorie type to keep sugar levels up, and maybe even some type of water purifying straw or equipment. All that stuff doesn’t take up much space or weight, and could be a lifesaver. Just happened upon this video but love experimental aircraft, so I will be subscribing. Hopefully no future mishaps. Great job on landing. May not have been textbook or pretty, but you know he saying. Any landing you can walk from is a good one!

Yeah, on the flight home I had a camera mounted in the cockpit that was within reach, so if I had any issues it was just one click of the record button away.

You could look into getting an automotive dash cam and mount it in your cockpit. Most are just powered off a USB port / 5V and automatically start recording on power up. They just record cyclically to a card and you can pull off footage as you need. There are even ones that record both forward and reverse at the same time.

While I'm not flying yet, I've recently done a lot of cycling. Weird stuff only happens to me when I don't have a camera running. So, now I mount the GoPro almost every time, just as a safety measure. Maybe Murphy doesn't like to be filmed... ;-)

It seems like most of my incidents happened right after I turned off my GoPro.

yes, but, now trent, you know that there is only reaction, there isn't time for - I want to start recording this for ... I agree with SenoreQueso, a automotive dash cam would be a good option, something happens, and when it's over you hit the button.... and to you others, bringing up gopro's, yes, that is why, more and more motorcycle riders are wearing them on their helmets, because things happen, or they are accused of things happening, and it can help them with the aftermath, and, yes, sometimes it can be used for other things too...

Rory On Air stop being a beg

The second engine on a General Aviation aircraft carries you to the scene of the crash landing. A twin engine cessna has 12 cylinders that can fail, and a Cherokee Warrior only has four. Twin is three times as likely to experience a cylinder failure!

Yeah, but the cylinders on the good engine can fly you AWAY from the scene of a crash, under some circumstances. And here's a thought-if you had to play Russian Roulette with a .357 magnum revolver, would you rather have 12 cylinders on your revolver, or 4?

LOL, I guess that's why so many small corporate a/c are twins! You need to go on the road with this routine.

I could never top Trent :)...but you're right...there's no substitute for that 2nd fan ...I know the 777-300 ER is tried and true, but...I still feel safer in the 747-400 during Trans-Pacific flights...4 is even better than 2 out there...

Vector Inglês ICAO. That other fan just gets you to scene of accident faster
