Probable cause

Climb not possible because of a downdraft which exceeded the performance capabilities of the airplane. Factors related to the accident were: inadequate location of the wind sock, the adverse wind conditions, and the trees.

Analysis

The 2970' rwy (elevation 820') was mostly surrounded by trees. With a temp of about 81 deg, the estimated density alt was 2700'. As the plt & psgr were taxiing to rwy 2 to take off, the wind sock, which was located below the tree tops, was noted to be limp. The plt rprtd that during takeoff, lift-off was at 65 mph after an aprx 600' roll & a climb was estabd at 75 to 80 mph. However, as the acft climbed abv the trees, a left drift was enctrd & the acft stopped climbing,although there was no apparent eng problem. By this time, there was insufficient rwy remaining to abort & the acft was apchg trees near the end of the rwy. The plt traded airspeed for alt to clear the trees & then the acft began to mush. Subsequently, it settled into smaller trees & came to rest with substantial dmg. The plt believed the acft enctrd a quartering tailwind & a downdraft as it was climbing abv the trees during takeoff & subsequently got behind the power curve.
