Reports now indicate that the front part of the engine landed at the gas station, and that the rear part of the engine landed a few blocks away (this is the third small debris area on land). This separation of engine parts appears to be consistent with the on-ground incident referred to in the NTSB report, where the disintegration of a disk in the high pressure section of the engine separated the front and rear sections. Note also that in the Philadelphia incident the uncontained failure of the engine also damaged the front wing spar. This is because the high pressure section of the turbine is at the rear, under the leading edge of the wing.

Stop it right now. You pre-empting a good 10,000 posts worth of conspiracy nonsense.

The only prob.... is that it was an Airbus that crahsed, not a Boeing 767.

F.O.D. kills (foreign object damage)

A simple monkey wrench left inside an engine air inlet cowling could have done this. F.A.A. will propose monkey wrenches are dangerous weapons and confiscate all monkey wrenches from A&P (airframe and powerplant) mechanics.

Adequacy of HPT Stage 1 Disk Design and Continuing Airworthiness Program

As previously discussed, it is possible that the cracks in each of the three HPT stage 1 disks discussed in this letter were the result of surface damage. However, the Safety Board recognizes that there is no clear evidence of surface damage on the area of the US Airways disk from which the crack originated and, therefore, it is also possible that the crack in that disk initiated from an undamaged blade slot bottom. Further, metallurgical examination revealed that in the area immediately adjacent to the fracture origination point, the radius between the slot bottom and the forward and aft faces of the disk conformed to the engineering drawing requirements for that radius, suggesting that the area from which the crack initiated also conformed. This possibility raises concerns that the design of the slot bottom of the GE CF6- 80C2 HPT stage 1 disk may not provide an adequate margin of safety even when the disk is manufactured to specifications. Further, during the Safety Board’s examination of the separated disk from the US Airways airplane, it was found that many of the radii between the slot bottoms and the forward and aft faces of the disk either exceeded or were less than the engineering drawing requirements for this radius.

Appearently, the problem is still under investigation!

Hmmm. After seeing the wreckage and reports on TV, my dear old Dad (pilot with thousands of hours flight time) said that he thought it was an engine failure with the fan (front part) separating from the rear.

Just like American 191 Chicago 1979

How to explain that rather than, or in addition to, the wing being found in the bay, it was the vertical stabilizer. (Mayor reported a part of wing, but it could have been the Vert. Stab). Can't envision how the engine coming unglued would rip that off.

"(this is the third small debris area on land)."

I heard some reporterette asking some high Mucky-Muck about the "third debris field". She seemed so proud to be able to use the new BUZZ TERM in her job. Betcha she asks for a raise!

I think we should follow the current Republican line and demand we taxpayers bailout GE immediately ...After all we don't want their crummy engines ruinning our economy by scaring people away from flying on near bankrupt airlines.....
