AAIB Report: Hawker Sea Fury T MK.20, forced landing following engine failure, near Button End, Cambridgeshire
皇冠体育app engine oil temperature rose and the oil pressure started to fluctuate. 皇冠体育app engine then seized, forcing the pilot to make a landing in a field near Button End, Cambridgeshire, 4 August 2020
During the second flight of Hawker Sea Fury T MK.20 (G-INVN) following maintenance, the engine oil temperature rose and the oil pressure started to fluctuate. 皇冠体育app engine then seized, forcing the pilot to make a landing in a field. 皇冠体育app aircraft was extensively damaged and both occupants suffered serious injuries.
Examination of the engine revealed extensive internal damage which resulted from the failure of a main engine bearing. 皇冠体育app cause of the bearing failure could not be identified but the investigation determined that contamination of the oil system was the most likely cause. 皇冠体育app investigation has not identified the need for new safety recommendations, but three areas for additional consideration by operators of similar aircraft are highlighted:
鈥� An engine oil chip detector may provide sufficient early warning of engine damage to indicate the need for remedial maintenance before further flight.
鈥� Forced landing or abandonment involves significant risk of injury in high performance aircraft. Operators and pilots can promote safe outcomes by providing clear safety briefings and ensuring all occupants wear effective head protection, as in this case.
鈥� Training in a relevant simulator can help familiarise pilots with prioritising the tasks necessary to conduct a safe forced landing, including the importance of maintaining sufficient airspeed, field selection, and the passenger and other emergency procedures that must be completed. 皇冠体育app AAIB recognises that there are few such simulators for high performance piston driven aircraft, and alternative means of achieving the same training aims may also be beneficial.
