What happened
During the takeoff phase, the pilot experienced a loss of engine power from the right engine. According to the pilot, the reduction in power was not an abrupt event but rather a slow and continuous decline. This loss of power occurred after the landing gear selector had been moved to the retract position.
At the time the power loss occurred, the aircraft's airspeed was measured between Vmc (86 mph) and Vy (120 mph). As the pilot reduced power on the left engine, the airplane began to roll toward the right side, where the engine had lost power. This maneuver resulted in the outboard portion of the right wing impacting the ground short of a taxiway.
The investigation
An examination of the wreckage was conducted to determine the sequence of events and mechanical condition. Investigators found that the propeller on the right engine was in the feather position. Additionally, the left engine was found to have been torn from the airframe during the event.
