Both engines lost power immediately following power increase during a stall recovery. The F-27 was engaged in a series of stall tests.

Probable Cause:

PROBABLE CAUSE: "Overtemperature of both engines, resulting in their simultaneous failure. This was caused by malfunction of the contact switches of No.1 engine propeller automatic flight safety pitch lock withdrawal system and the pilot's failure to withdraw the locks manually by placing the HP fuel cock levers in the 'lockout' position."
