Written off (damaged beyond repair) 06-07-2010 in a landing accident at Cambridge Airport, Teversham, Cambridgeshire: On the third of three planned landings the nose landing gear collapsed and the aircraft slid to a halt on its nose. The investigation revealed that a lack of lubrication on the link plate attachments that secure the down lock actuator to the down lock link is likely to have caused a restriction and prevented the complete engagement of the down lock. The pilot was unaware that the down lock had not engaged completely. No injuries sustained to the pilot (the sole person on board). According to the following extract from the official AAIB report into the accident:
"The purpose of the flight was for the pilot to perform three landings to maintain currency to fly with passengers. The first two landings were performed successfully and the pilot confirmed that, on each occasion, all gears were down and locked with three green indicator lights showing.
The third circuit was flown as a practice low‑level bad weather circuit with the pilot confirming that the gear was down and locked at approximately 200 feet on final approach. The pilot considered the approach and touchdown to be normal but as the nose was lowered, it continued beyond the normal landing pitch attitude and made contact with the runway.
The propellers also contacted the runway, the engines stopped and the aircraft slid to a halt. The pilot, who was wearing a lap and diagonal harness, escaped uninjured. The Airport Fire Service attended the scene, reported a small fuel leak from the left wing and laid down foam as a precaution."
Nature of Damage sustained to airframe: Per the AAIB report "Propellers bent, nose cone and nose landing gear doors
abraded". The damage sustained was presumably enough to render the airframe as "beyond economic repair", as the registration G-BATN was cancelled by the CAA on 16-02-2012 (some 18 months later) as "Permanently withdrawn from use"
