What happened
During a series of training maneuvers intended to restore flight currency, a Grumman G-21 was involved in a fatal accident. The pilot, who had not operated this specific aircraft type for two years, had planned a sequence of three takeoffs and landings to regain proficiency. Following the first two successful full-stop landings, the aircraft was engaged in its third takeoff attempt.
Shortly after departing the runway, the aircraft reached a nose-high attitude while remaining below 100 feet of altitude. The plane then experienced a left roll and descended steeply into the ground, resulting in a post-impact fire. There were zero survivors reported in the crash.
Findings
Investigation of the wreckage revealed that the flap actuators were positioned at a 30-degree extension, representing a half-flap configuration. Interviews with experienced pilots of the G-21 indicated that such flap settings are not standard for takeoff procedures in this model. It was noted that the aircraft's turboprop engines provided significant power relative to the light weight of the plane, which could cause the aircraft to become airborne prematurely when flaps are extended.
Witnesses observed that the engines remained functional and were producing power until the moment of impact, as evidenced by rotational damage to the propellers. No mechanical failures were identified in the period leading up to the accident, suggesting that the premature liftoff due to flap configuration was a critical factor in the loss of control.
