Incident Sequence
Shortly after takeoff from Nogales Airport, while climbing, the pilot reported an engine failure to ground control. Controllers cleared the flight for an emergency return and landing. During the return, the airplane's speed decreased to an insufficient level, leading to an aerodynamic stall. The stalled aircraft then crashed in flames into an open field.
Damage and Fatalities
The crash and ensuing fire completely destroyed the aircraft. All twelve individuals on board sustained fatal injuries, resulting in the deaths of all occupants.
Probable Cause
The official probable cause of the accident was an engine failure for an undetermined reason. The investigation also indicated that the aircraft may have been overweight at the time of the accident, a factor that could have contributed to the engine failure.
