Descripción:
A high-stop (cruise pitch) hang-up of both propellers at low airspeed (while the aircraft was entering a stall maneuvered) caused excessive temperatures in the turbine sections of both engines. When the training crew tried to recover from the simulated landing stall, the engines didn't respond. The aircraft crash-landed in the desert. Excessive wear of the propeller hub contact switches was due to maintenance instruction deficiencies. Contributing was the crew non-adherence to prescribed procedures.
