What happened
During the initial climb phase following departure from Salvador Airport, the aircraft experienced a mechanical failure in its right engine. In response to the loss of power, the pilot-in-command initiated an emergency return to the airfield.
As the aircraft was performing its final turn to align with the runway, it lost sufficient airspeed and entered a stall. The aircraft subsequently crashed a few hundred yards from the runway threshold. The impact resulted in the total destruction of the aircraft type and caused injuries to all six occupants on board.
Findings
Investigations into the incident focused on the management of the engine failure. While the specific reason for the right engine's malfunction remained unconfirmed, a critical error was identified in the crew's response. The pilot failed to feather the propeller on the malfunctioning engine, which significantly increased aerodynamic drag and directly contributed to the loss of lift and the subsequent stall.
