Probable cause
The pilot's failure to maintain airspeed after takeoff while using improper obstacle takeoff procedures. Factors include excessive flap extension.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The private pilot initiated a takeoff from a sod runway at 4860 feet above sea level with the mixture control in the rich position and the flaps extended twenty degrees. Trees are located at the departure end of the runway, but they can be avoided by a slight right turn after takeoff, which allows flying over a river. The aircraft owner's manual states that normal and obstacle clearance takeoffs are performed with wing flaps up, but does provide for use of ten degrees of flaps for takeoffs with no obstacles ahead. A witness observed the aircraft lifting off in a stall configuration, climbing no higher than the trees before the left wing dropped and it crashed in a field adjacent to the departure end of the runway.
