Aircraft involved

Probable cause & findings

AN INADVERTENT STALL DURING INITIAL CLIMB. THE HIGH DENSITY ALTITUDE AND A PREMATURE LIFTOFF BY THE PILOT WERE FACTORS.

Factual narrative

THE PILOT ATTEMPTED TO TAKEOFF FROM THE AIRPORT WITH A DENSITY ALTITUDE OF 7500-8000 FEET UNDER NO WIND CONDITIONS. THE AIRCRAFT WAS FULLY FUELED AND NEAR ITS MAXIMUM GROSS TAKEOFF WEIGHT AND THE PILOT DID NOT ADJUST THE FUEL/PASSENGER LOAD TO COMPENSATE. DURING THE TAKEOFF THE AIRSPEED DECAYED BELOW STALL SPEED AND THE AIRCRAFT STALLED AND DESCENDED BACK TO THE RUNWAY. INSUFFICIENT ALTITUDE WAS AVAILABLE DURING THE STALL TO ENABLE THE PILOT TO EXECUTE A SUCCESSFUL RECOVERY. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
