On 8 March the Air Accidents Investigation Branch published its report on the wheels-up landing of Naval Aviation Ltd’s de Havilland Sea Vixen FAW2, XP924/G-CVIX, on 27 May 2017, upon returning to its base at Yeovilton following a display at Duxford. The report summary reads, “The pilot had slowed the aircraft and was configuring it for landing, but despite several attempts, using the normal (green) and stand-by (red) hydraulic systems, the landing gear failed to unlock and lower. After consultation between the pilot, air traffic control and the operator’s chief engineer, the decision was taken to do a wheels-up landing. This was carried out; the pilot landed the aircraft and came to a stop on the runway without further incident. The pilot made the aircraft safe and vacated the cockpit unaided.
“The landing gear failed to lower because of a mechanical break-up within both the normal and stand-by hydraulic systems pumps. The break-up was caused by seizure of the pistons within the hydraulic pumps, probably due to the presence of a contaminant. Forensic work is continuing to identify the contaminant and its source.”
The pilot, Cdr Simon Hargreaves OBE, was awarded a ‘green endorsement’ commendation, his airmanship minimising damage to the aircraft. Rear Admiral Keith Blount, the Assistant Chief of the Naval Staff, cited Hargreaves for exceptional skill in the incident.
