Default Aircraft Engine Failure over Denver.

Some amazing pictures coming out of A Boeing 777 engine cowl on someone’s front lawn after a United Airlines Boeing 777 suffered engine failure on a flight to Honolulu.

Also some pics of the plane in flight with a clearly badly damaged engine.

Thankfully looks like no injuries.

Just caught it on a TV news channel. Not sure why the engine was still there as they are designed to shear and clearly that jet would have been better off without it after such a failure. Sadly, some crews on a flight deck don,t cope too well with an engine down or out and the recent loss of a 737 in Indonesia looks likely to be a case in point. But well done to the crew in this case of a 777 for getting it safely down.

Yes, thankfully no one’s hurt. Would that have been a Rolls Royce or GE unit?

Boeing, boing, boing! The more I read about their manufacturing methods the more I worry! It seems that when they were doing the "pickle fork" inspections the investigating technicians have found a number of bits of "manufacturing debris" in the voids! Anything rolling around next to wiring or hydraulic systems is a worry!

It had the Pratt & Whitney engine option. Not a good day for P & W as a 747 using its engines also suffered an engine failure on the same day. Click

Yeah, but RR had that issue with a gas pipe/duct thinning excessively to the really, really hot temps. Quantas had the first failure (if I remember they shut the engine down just in time) but was evident in the rest of the fleet's engines and was responsible for grounding of fleet's until the component had been changed.

The GE engine might be just a one off!

Well, what is the alternative if a wrecked engine destroys a wing or an aircraft? The choice as in many cases must be of damage limitation ... I would guess.

If the shear pins are for location only then surely by definition they serve no other purpose ... assuming that you are correct.

It might be if it were relevant to this thread. But, is it?

The shear pins are for location only and appear to take the thrust load. There are many more bolts holding the whole engine assembly to the wing. The shear pins protect the bolts from being under shear stress.
