NTSB Narrative Summary Released at Completion of Accident

During the takeoff climb, when the airplane reached an altitude of 35 feet, it encountered a downdraft caused by trees on the west side of the runway. The airplane seemed to "sag," was unable to continue its climb, and impacted the tree line. The pilot reported no mechanical deficiencies with the airplane. Witnesses also reported that the takeoff and initial climb appeared normal; however, at about 30 feet the airplane did not continue to accelerate or climb prior to impacting the trees.

NTSB Probable Cause Narrative

The pilots inadvertent encounter with a downdraft, which resulted in the airplane impacting trees.
