Narrative:
Avro Anson Mk.1 NK622, RAF Biggin Hill Station Flight: Written off (damaged beyond repair) 9 June 1946 in a landing accident at RAF Biggin Hill, Biggin Hill, Bromley, Kent.

The aircraft was engaged on an air experience flight from RAF Biggin Hill, with five persons on board: pilot plus four ATC (Air Training Corps) Cadets. During the final approach to Biggin Hill at the end of the sortie, the port undercarriage would not lower. The reason for this was that the drive chain, which moves the undercarriage leg, had come of its sprocket.

As a result, the pilot landed Anson NK622 on the starboard undercarriage leg only, but the Anson was damaged when the port wing contacted the ground, as the aircraft slowed during the landing run. The Anson then ground looped off the runway and was severely damaged

Although Anson NK622 was written off as FACE (Flying Accident Cat. E) and therefore "damaged beyond economic repair", the five persons on board were uninjured.
