What happened
During the takeoff roll, the aircraft experienced a gradual reduction in power from the right-side engine. This loss of thrust occurred immediately after the pilot moved the landing gear selector to the retract position. At the moment the power loss was occurring, the airspeed was measured between 86 mph and 120 mph, placing it between Vmc and Vy.
As the pilot decreased power on the left engine to manage the situation, the aircraft began rolling toward the inactive right engine. This maneuver led to the outboard section of the right wing striking the ground before reaching a nearby taxiway. The incident resulted in zero fatalities and zero injuries.
Post-accident inspection of the wreckage showed that the propeller on the right engine had been moved to the feather position, while the left engine had been completely separated from the airframe during the event.
Findings
The investigation determined that the primary factor was a loss of power in the right engine for reasons that remain unidentified. The secondary contributing factor was the pilot's inability to maintain directional control of the aircraft following the engine failure.
