Overview
Witnesses at the airport reported that the wind conditions were from the west at approximately 20 knots, with peak gusts reaching about 37 knots. They stated that the wind sock indicated a direct crosswind relative to Runway 3/21. The pilot initiated the takeoff on Runway 21.
Takeoff Sequence
According to witness accounts, during the takeoff roll, the aircraft settled back onto the runway several times before becoming airborne. It reportedly did not achieve a positive rate of climb. One witness observed the left wing drop, after which the aircraft began to spin towards the ground.
Aircraft Weight and Density Altitude
The pilot estimated that the aircraft was approximately 51 pounds over its approved gross weight. The density altitude was calculated to be about 5,700 feet. No preimpact mechanical failure or malfunction of the aircraft was reported.
Investigation Findings
The investigation did not specify any mechanical issues. The combination of overweight condition, high density altitude, and gusty crosswind conditions were noted in the witness reports and pilot estimation.
