HPT FAILURE ON A HIGH POWER RUN

AlekSmart

Yikes !! :eek:

I hope the ground-crew were wearing their hi-viz gear ......:)

However it`s interesting to note that the engine shrouds performed their task and prevented the errant HPT blades from exploring further into the atmosphere ?

This is how the industry learns....expensive lesson yes,but one which will yield results !

Looks to me that part of the disk escaped and is buried in the outboard side of engine #2.

What's the lesson to be learned?

Nice spot. I believe it was number 4 that failed and the part of disk is embedded in number 3 engine.

This is old news! The incident in question occured on June 2nd 2006 in LAX.

What your looking at is a Boeing 767 equipped with GE CF6-80A Engines. The number 1 engine HPT stage 1 let go. The picture of the embedded rotor is on the number 2 engine. It let go and cut right thru the underbelly fairings on it travels before embedding in the engine!

Stay well clear of all 4 ingins on a 767 ?

these were always my favourite (3.23 for the exciting bit)

blade off tests, remember the whole of rolls royce used to hold its breath for those - felt like it anyway

only ever got up there doing probe icing tests, never for any of the biggies
