Confidence Rating: Accident investigation report completed and information captured
The pilot made a full power check of the engine and adjusted the mixture prior to takeoff. Not wanting to overheat the cylinders during climbout, he enriched the mixture 'a little.' The pilot said after lifting off, 'it became apparent at around 250 feet that the power was deteriorating and I leaned the mixture a little and made a shallow rudder turn to the right, hoping to pick up speed and get a gradual climb, when the engine quit and the plane mushed to the ground, stalled, and crashed.' Engine examination disclosed no evidence of preimpact failure or malfunction. When questioned by an FAA inspector at the hospital, the pilot said there was 'nothing wrong with the engine,' and that all engine instruments appeared to be normal during the takeoff and climb. He admitted he had not performed weight and balance calculations, nor had he consulted the Cessna 150 PILOT'S OPERATING HANDBOOK for high altitude performance data. It was computed the airplane was 32.8 pounds over maximum gross weight (1,600 pounds), and the density altitude was 7,844 feet msl. The pilot also admitted that 'a sleepless night clouded [his] judgment.'

Probable Cause: An inadvertent stall/mush. Factors were high density altitude, weight and balance exceeded, and pilot fatigue.
