Written of (destroyed) 15/1/1975 when crashed at Beech Farm, near Barnby Moor, Nottinghamshire. Whilst engaged on a gas pipe line survey in the East Midlands area, the aircraft was seen to go out of control and crash. On impact the aircraft broke up and both occupants were killed; there was no fire.
The accident resulted from the failure of the tail rotor spar and the consequent detachment of one of the rotor blades . The failure was due to fatigue, originating from severe corrosion pitting of the tail rotor blade steel spar at the aerofoil root. Corrosion pitting was found to have affected 18 per cent of the section thickness adjacent to the crack
All British operators of the Hughes 269 models were alerted five days after the accident and required to X-ray their tail rotors. Visual examinations for corrosion resulted in rejection of 14 from the sample of 30 spars inspected. The US Federal Aviation Administration issued an airworthiness directive calling for the same check to all US-registered Hughes 269 helicopters.
Registration G-BABN cancelled by the CAA as "destroyed" 24/2/1975
