engine separation

[cforst513]

you guys remember that 747 that lost an engine in Lake Michigan? well, as we all know, the engines for a 747 are mounted on the wings. has there ever been a recorded engine separation for a fuselage-mounted engine (like on an MD-80)? would flight ever be possible with just the one engine attached or does it really just depend on the situation/amount of damage?

In 1985, an AAL B727 physically lost #3 because a big blue ice ball smashed into it. Happened between Las Cruces and Demming IIRC. The way I heard it, the crew didn't know the engine had actually departed the airframe until after landing...

There was a Hawker that had an engine shot off the pylon by a heat seeking missle over Africa a bunch of years ago... They landed fine... Hawker was even using the picture in their adds for a while...

did the hawker have 3 engines? what if this was to happen to a jet like a Citation (spare the jokes, please) with only 2 engines? could they continue the flight? is it just like an engine-out emergency?

also, how could the 727 pilots NOT know that they were missing an engine? wouldn't they figure it out in lost airspeed/low fuel flow/low oil pressure/etc/etc/etc?!

I belive all hawkers are 2 engine airplanes.

As far as not knowing if it fell off, there aren't any indications if the engine is there just a buch that will tell you it isn't running properly (or at all) and on planes like that you can't see the engines from up front. So you will know the engine failed but not that it's gone. Jet engines don't generally create much drag like a failed prop engine. ever notice the big difference in rudder when you feather a prop? doesn't happen in a jet

Hawker is only 2 engines, like a Citation... Falcon's (50, 900 and 7X) are the only 3 engined Corporate jets...

As far as the 727 not knowing it fell off... They surely knew they "lost" the engine (as in it was inoperative) however they appearantly didn't know they "lost" the engine (as it physically departed the airframe)...

Yes, they of course knew they had suffered a serious engine failure. It was just a surprise to everyone that it had actually departed the airframe.

haha, yeah, i guess i should have figured that.

They can fly on one engine with relatively no problem.
