Accident Details
On 21 April 2001 at 0950 UTC, a Gulfstream AA-5B, registration G-BGPH, was involved in an accident at Biggin Hill Airport, Kent. The aircraft was manufactured in 1979 and powered by one Lycoming O-360-A4K piston engine. The flight was private, with the pilot and three passengers on board.
Sequence of Events
The pilot, aged 47 with a Private Pilot's Licence and 136 total flying hours (46 on type), was preparing for an introductory flight for an adult and two children. He was demonstrating the use of the checklist routine while the parking brake was selected ON. The engine was primed five times and the throttle opened. The engine started immediately, and the aircraft moved forward. The pilot confirmed that the brakes were ON and applied both toe brakes, but the aircraft turned to the left and struck a container, resulting in damage to the right wing and the outboard section of the left wing.
Aftermath
There were no injuries to the occupants, and they vacated the aircraft through the normal exits. The pilot did not inform Air Traffic Control at the time of the accident; however, it was brought to their attention by a local flying organization. A functional check of the brakes by the maintenance organization following the accident showed them to be working normally.
Probable Cause
No probable cause was stated in the source.
