Narrative:The pilot and two passengers landed on a short grass airstrip that the pilot had never landed on before. He boarded a third passenger, and performed a mental calculation for takeoff performance. He decided to takeoff uphill and into the wind. The airstrip was surrounded by tall trees, and the density altitude was about 6,000 feet. The airplane was at or near its maximum gross takeoff weight. The pilot selected 20 degrees of flaps for the takeoff, and an additional 20 degrees during climbout, despite information to the contrary on the use of flaps published in the airplane's pilot operating handbook (POH). The airplane impacted trees at the end of the runway after the pilot's attempt to abort the takeoff just prior to impact. According to the performance charts found in the POH, the airplane would have been unable to clear the trees under the given conditions. The pilot stated that the engine was unable to produce full power at takeoff. Subsequent testing of the engine did not reveal any preimpact mechanical malfunctions.
Probable Cause: The pilot's failure to perform proper preflight planning for the flight, and his failure to obtain/maintain clearance from trees during takeoff. Factors contributing to the accident include the pilot's delayed remedial action, his improper use of flaps, and high density altitude.
