Narrative:
The HS-748 failed to become airborne and crashed into the sea 50m offshore. The takeoff runway (09-27) had a length of 3555 feet.

PROBABLE CAUSE: "It was concluded that the accident was caused by the locked condition of the elevators which prevented the rotation of the aircraft into a flying attitude. It is likely that the elevator gust-lock became re-engaged during the pilot's pre-take-off check, and that this condition was not apparent to either pilot until the take-off was so far advanced that a successful abandonment within the overrun area could not be reasonably have been made. The re-engagement of the gust-lock was made possible by the condition of the gust-lock lever gate plate and gate-stop strip."

Classification:
Locked rudders/ailerons/gustlock
Runway excursion
