Narrative:
Slingsby T.67 G-BJCY left Redhill Airfield, for a local flight, early in the evening of 12 June 1987. The pilot and one passenger were on board. Twelve minutes later it was seen at about 500 - 600 feet above ground level, just south of Effingham and Great Bookham, pulling up into a loop. At the top of the loop the Slingsby's engine cut. It continued through the loop before diving, almost vertically, and disappearing, behind trees and bushes, before striking the ground at a steep angle, nose down and banked to starboard. Both of those on board were killed on impact.

The Slingsby was destroyed in the crash and its registration was cancelled as such by the CAA on 11 April 1988. The AAIB failed to find evidence that the pilot had been trained to perform aerobatics. The cause of the crash was attributed to too lean a fuel/air mix and keeping the engine running when pulling negative gravity whilst inverted, something which it was not designed to do.
