Narrative:
de Havilland Canada DHC-1 Chipmunk T.10 WB729, Aberdeen UAS, RAF: delivered 12/10/1950. Written off (destroyed) 10/5/52 when crashed at Home Farm, Haddow, 2 miles North-West of Tarves, Aberdeenshire. Both crew killed

The aircraft failed to recover from a spin, and was destroyed on impact with the ground. Examination of the wreckage revealed that the wheel brakes had been applied after takeoff, and that this prevented the pilot from using the full rudder movement during spin recovery.

Crew of Chipmunk WB729:
Squadron Leader Ian Lewis McGregor Hallam (pilot) RAF : Commanding Officer of Aberdeen University Air Squadron at the time
Cadet Pilot John Lawrie (Pupil pilot under instruction)

The reported crash location is two miles north west of Tarves, Aberdeenshire, a small village, situated in the Formartine area of North East Scotland and lies between Oldmeldrum and Methlick.
