Narrative:
de Havilland Canada DHC-1 Chipmunk T.10 WB737, 11 RFS (Reserve Flying School): Written off (destroyed) 27/3/1951. The aircraft was seen to enter a spin from what seemed to be an adequate altitude, with enough height to initiate a safe spin recovery. However, no recovery was made from the spin, and the aircraft struck the waters of the River Tay, near Kingoodie, Angus.

Why the pilot did not recover from the spin was never established by the RAF Board of Inquiry: it is possible that the pilot may have allowed the spin to continue for too long before starting recovery action, and the flatter spin characteristics on this occasion may have led him to take the incorrect and inappropriate recovery action. Of the two person on board, the pilot was killed, and the occupant of the rear seat survived with injuries

Crew of Chipmunk WB737:
Sergeant William MacKay RAF (pilot) - killed on active service 27/3/1951
Sergeant R L Robinson RAF (rear seat passenger) - survived with injuries

Wreckage recovered by (and to) 63 MU RAF Edzell, where scrapped after completion of accident investigation procedures. The crash location was into the River Tay near Kingoodie, a hamlet about 4 miles (6.4 km) south west of Dundee, but in the region of Perth and Kinross, Scotland at approximate co ordinates 56.451840°N 3.074401°W
