Narrative:
A Dornier 328 prototype was conducting a test flight to prove compliance with JAR 25.177.
The aircraft was flown at FL150 with a 25 degree flap setting, landing gear down and at a speed of 1.13 times the stall speed. At the end of this manoeuvre, the aircraft reached a 20 degree yaw angle. The pilot then experienced a partial buffet on the tail and the Dornier then rolled steep nose down. The pilot instructed the co-pilot in German to reduce the engine power. This was not understood by the U.S. test pilot. Shortly afterwards all six blades of the left engine separated instantaneously when the aircraft passed an inverted position.
The fuselage was severely damaged by subsequent propeller strike. The aircraft landed safely.
