Manassas, VA, USA
N4300E
AERONCA 7AC
According to the pilot, while approaching the destination airport, he entered the traffic pattern by crossing the runway about 850 feet above ground level (agl). He performed a "wing over," then turned back over the runway and began a turn to the left downwind leg of the traffic pattern. During the turn, the rudder "stuck," and the airplane entered a left spiraling descent. The pilot added full power, pushed the control stick forward, and attempted to apply right rudder. He attempted to dislodge the rudder by reaching for the passenger rudder pedal underneath and behind his seat but was unsuccessful. About 100 feet agl, the airplane exited from the spiral and continued to descend into the ground, where it came to rest inverted, sustaining substantial damage to the wings and fuselage. According to a witness, the airplane was about 400 feet agl when it entered a hard left turn and then a spin. After 1.5 revolutions, the airplane exited the spin and began to pull out of the resulting dive before it impacted the ground. Examination of the wreckage verified full freedom of movement of the rudder and rudder pedals. There was no evidence of any preimpact mechanical anomalies with the airplane.

He attempted to dislodge the rudder by reaching for the passenger rudder pedal underneath and behind his seat, but was unsuccessful. Around 100 feet about ground level, the airplane exited from the spiral, continued to descend into the ground, then came to rest inverted, resulting in substantial damage to the wings and fuselage. According to a witness, the airplane was about 400 feet above ground level when it entered a steep left turn, and then entered a left hand spin. After one and one half revolutions the pilot recovered from the spin into a dive. The pilot was unable to recover from the dive before ground impact. A subsequent examination of the wreckage performed by a Federal Aviation Administration inspector verified full freedom of movement of the rudder and rudder pedals. There was no evidence of any pre-impact mechanical anomalies with the airplane.
The pilot did not maintain adequate airspeed while turning to the downwind leg, which resulted in an aerodynamic stall and spin.
