The taxiway for the particular strip is a continuation of the gravel centre section of the strip. The taxiway then makes a right angled turn. After a normal landing the pilot proceeded straight ahead, along the taxiway but failed to negotiate the turn. The aircraft entered a ditch and the left wing struck the ground. No fault was found with the aircraft's brake or steering systems that could have contributed to the accident. Insufficient attention was paid to the operation of the aircraft and the turn was attempted at too high a speed.
