Accident Details
Approximately two minutes after departure from Albuquerque Airport, while climbing, the right engine failed after the hydraulic pump became inoperative. The pilot shut down the right engine and feathered its propeller before initiating a turn back to the airport. The aircraft then nosed down and crashed in flames. The pilot and a passenger were killed; four other occupants were injured.
Probable Cause
The official investigation determined that the probable cause of the nose-down and subsequent crash was inadequate maintenance and inspection.
Contributing Factors
Several contributing factors were reported: failure of the hydraulic pump due to improper installation; engine structure issues involving pistons and piston rings; lack of lubrication of a specific part; overheating; the pilot's failure to follow approved procedures; high outside air temperature; high density altitude of 7,750 feet; rough terrain; and landing gear extended during a go-around from a gear-up approach.
