A UAL 777 suffered an uncontained engine failure soon after takeoff, raining parts down on a Denver suburb.
But the engine itself seemed to keep turning and burning.
No word if the pilots had to be seen by medical professionals to extract some of the seat cushioning from their butts.

COMMENT MODERATION IS IN EFFECT UFN. This means that if you are an insulting dick, nobody will ever see it.
That 777 was one of the first ten built and used in the test fleet. Of course, it may not have the original engines and, in any case, would have been through maintenance any number of times.
ReplyDeleteI think the age of the aircraft is moot, as far as it being an engine flame-out, though the parts raining down out of the sky part is bothersome. Fortunate it wasn't over Boston (or Quincy), NY or LA.
ReplyDeleteMost probably were. Initial look it spit a compressor blade (#11) and chipped #10.
ReplyDeletePilots were pros, so medical intervention to remove upholstery probably not necessary. More likely some mechanics were sent in to rock them, breaking the suction on the seats.
ReplyDelete...and a 747 did the same thing on the same day, in the Netherlands. One person hurt on the ground.
ReplyDeleteI don't see what the problem is. They have TWO of those things.

ReplyDeleteFrnk, the 747 incident.
ReplyDeleteTo All The B777 is catching flak. The engines are B & W. If the news reporting is correct United is the only carrier opting to use the B&W engines. Any research into the reliability of these engines may produce a clue as to the cause of the failure. P&W is publicly keeping quiet.

CM, I like the phrasing on the 747 report. Saying that the plane "Began to distribute engine parts" sounds like Santa Claus bringing turbine blades to all the good boys and girls.
ReplyDeletePardon my ignorance here, but I have questions. Is there no fire suppression in the engine or did it get maybe get torn off from the Kaboom?
ReplyDeleteAlso, is there no brake mechanism for the engine? It would seem to continue to be a hazard as long as it continues to rotate.
I can only imagine the uniform change needed for the cabin crew after such an adventure.
Also, do car insurance policies cover airplane fallout damage, or is it up to the owners to sue the airline for damages? That one guy's pickup sure took a beating, yet it didn't touch his trailer.

If any cars were damaged, I’m sure Farmer’s Insurance will be using the incident !
ReplyDeleteLOL ~ Most "insurance" only cover vehicles in operation.
ReplyDeleteHurricanes, Tornados, Volcanoes, stuff falling out of the sky is extra.
I can only imagine what kind of noise it was making!
ReplyDeleteWell, if Farmers covered the guy whose convertible was filled with cement, they ought to cover this.
ReplyDeleteW3ski,
ReplyDeleteTypically, an engine fire switch shuts off fuel and hydraulic feeds to the engine....basically the idea is to starve the engine of anything that can burn. The failure may have stopped that function from working completely, or the flames that you are seeing are only the bearings in the engine grinding themselves to pieces and generating flames that way. I am frankly not sure.
And the engine itself is just “windmilling”. There is no power going to it, but the airflow from the motion of the airplane keeps the turbine assembly spinning. I suspect that a braking mechanism like that would be extremely counterproductive, as it would be a massive source of aerodynamic drag. I don’t concretely know the numbers involved, but I wouldn’t be surprised if stopping turbine rotation entirely might also make the aircraft go out of control, as the control surfaces of the airplane would not be able to generate enough force to counteract the drag generated.
MarkS, I disagree. I've talked to dozens of pilots declaring an emergency, and that pilot was rattled, not calm.
