Aircraft Accident/Incident Report

Davenport, Iowa 52804
Saturday, September 1, 2012 13:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The accident airplane was one of three airplanes in an airshow performance. After overflying the spectators and while flying away from the flight line, the airplanes executed a “crossover break” maneuver, at the beginning of which the accident airplane was in the left wing position. As planned, the lead airplane would climb while the left wing position airplane would enter a right turn and the right wing position airplane would enter a left turn with adequate longitudinal spacing. During the maneuver, the accident airplane entered the right turn as planned, but then descended and impacted the terrain. A postimpact fire ensued. No evidence of an in-flight collision with either of the other airplanes was observed. Witnesses reported that they did not observe any movement of the airplane's flight control surfaces before the airplane impacted terrain, which would be inconsistent with the pilot attempting to recover from the descent. The postaccident examination did not reveal any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause Narrative

The loss of airplane control for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded operation.
