What happened
During an air show, a twin engine airplane was performing a series of fly-by maneuvers. After successfully completing two circuits, the aircraft was on its third downwind leg at an altitude between 600 and 800 feet AGL when the right engine lost power. At the time of the incident, the main landing gear had already been deployed, as the pilot intended to land on the runway.
In response to the engine failure, the pilot attempted to restart the right engine by advancing the throttles. However, the engine failed to relight. The aircraft subsequently struck the ground short of the runway. The flight involved five occupants, all of whom sustained injuries, with four serious injuries reported.
Findings
Post-accident investigations focused on the condition of the right engine and the aircraft's configuration. While the right engine's propeller was found in an unfeathered, fine pitch position, the pilot did not report feathering the engine following the failure. An inspection of the right engine showed no signs of an anomaly prior to the impact. Due to damage sustained during the crash, the magnetos and carburetor of the right engine could not be functionally tested.
