Probable cause

The pilot's failure to maintain a sufficient airspeed margin while on final approach, and, after encountering a down draft, his failure to correct the resulting descent rate and maintain a glide path which would maintain obstacle clearance.

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.

In flight collision with objectApproach - vfr pattern - final approach
Object - tree(s)
Weather condition - downdraft
Airspeed(vref) - not maintainedPilot in commandCause
Descent - not correctedPilot in commandCause

Analysis

The pilot said he was on approach to his private airstrip and he let the aircraft get low and slow. The aircraft encountered a downdraft which the pilot was unable to correct and the airplane collided with trees at the approach end of the runway.
