NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot reported that prior to takeoff he 'inadvertently' set the flaps to 20 degrees. He reported flying in ground effect for about 600 feet prior to climbing to an altitude of about 30 feet above the ground. The airplane then stalled, impacted the terrain, and a post impact fire ensued. Inspection of the airplane revealed the flap actuator was extended 4.8 inches which correlates to 29 degrees of flaps being extended. The pilot reported he was used to flying a Piper Cherokee and 'incorrectly thought that just like a Cherokee a 20 degree wing flap [setting] would shorten [the] ground roll.'

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the pilot inadvertently stalled the airplane during the initial takeoff climb. Factors associated with the accident were the pilot's inattentiveness at lowering excessive flaps for takeoff.
