Narrative:
A de Havilland Canada DHC-6 Twin Otter, N930MA, was damaged in a takeoff accident at San Juan, Puerto Rico.
The pilot stated that on takeoff roll as the nose wheel was lifted at approx 60 knots, the aircraft veered sharply to the left, ran off the runway and collided with the glide slope building. No evidence was found during the examination of the aircraft structure, flight control systems or right powerplant to suggest a failure or malfunction prior to impact with the glide slope building.
Probable cause:
aircraft handling..poor..pilot in command
rotation..premature..pilot in command
directional control..not maintained..pilot in command
