This was an AA 767 undergoing a highspeed test run when the high pressure turbine decided it's be happier free from the confines of the engine shroud. A bit was found half a mile from the site. The boom was impressive according to reports.






The 767 was undergoing a high-power run when the #1 engine had a HPT failure. The HPT let go and ended up puncturing the left wing, #1 engine, and peppered the fuselage. The L/H wing punctures went through to the fuel cells and caused an aircraft fire to erupt. One section of the turbine disk exited the engine and sliced through the air conditioning bay, lodging itself in the outboard side of the #2 engine. Two days later, another 18 inch piece of the turbine was found about half a mile from the site of the explosion.








The three mechanics performing the run escaped serious injury.

The NTSB is investigating the incident.
