Category: Accident

A 7-minute takeoff event resulted in a significant engine oil temperature increase, followed by an engine shutdown and relit, and ultimately a fire in the 3rd engine. A stall maneuver triggered further temperature rise, culminating in a fire in the 4th engine, leading to a belly landing. The incident was initiated by a propeller reduction gear failure.A 7-minute takeoff event resulted in a significant engine oil temperature increase, followed by an engine shutdown and relit, and ultimately a fire in the 3rd engine.

Description
Some 7 minutes after takeoff the no. 3 engine oil temperature rose. The engine was shut down and relit when oil temperature had fallen. Following demonstration of a stall manoeuvre, the temperature again rose followed by a fire in the no. 3 engine nacelle. The fire could not be contained, so the no. 4 engine was stopped as a precautionary measure. On approach to Filton the no. 1 and 2 engines both quit. The were quickly restarted, but an emergency belly landing was made on the mud flats of the Severn Estuary. PROBABLE CAUSE: “Mechanical failure of the propeller reduction gear.”
