What happened
Shortly after takeoff, the pilot was managing the cabin environment controls while executing a turn. During this phase of flight, the cockpit door unexpectedly opened. Rather than addressing the immediate issue by turning off the fresh air blower, the pilot inadvertently activated the fuel boost pump.
This action caused the engine to flood, resulting in a complete loss of power. The pilot attempted to return to the airport but was unable to reach the runway threshold. The aircraft landed short of the runway, coming to rest on the ground adjacent to the airfield.
The investigation
The investigation focused on the sequence of events leading to the loss of power and the subsequent landing outcome. Examination of the flight dynamics confirmed that the engine failure was consistent with fuel flooding rather than mechanical malfunction or fuel exhaustion. The physical evidence supported the narrative that the pilot's reaction to the open cockpit door led to the incorrect control input.
Findings
The primary contributing factor was the pilot's misidentification of the controls during a high-workload moment. The unexpected opening of the cockpit door diverted attention from standard engine management procedures, leading to the activation of the fuel boost pump when it should have been off. This error directly caused the engine to flood and lose power.
Safety message
This incident highlights the importance of maintaining strict adherence to standard operating procedures during abnormal situations. Pilots must be trained to prioritize critical flight controls and avoid unnecessary changes to engine management systems unless specifically required by the emergency checklist.
