Confidence Rating: Accident investigation report completed and information captured
According to the pilot the aircraft had experienced intermittent stiffness in the left wheel during taxi maneuvers. On the day of the accident the aircraft was maneuvered by hand out of the hangar, with the left wheel moving freely. It was necessary to apply very positive brake pressure to hold the aircraft stationary during the pre take-off power check. On the take-off roll intermittent resistance was experienced, however, the aircraft accelerated normally and take-off was continued. On touchdown, runway 05 at Pilansberg airport, the left wheel locked, the aircraft veered sharply to the left, ground looped and came to rest on it's nose on the side of the runway. The last Mandatory Periodic Inspection (MPI) prior to the accident was certified on 25 May 2002 at 10 908.38 airframe hours. Since the MPI was certified a further 31.23 hours were flown. According to the pilot a total of 66 landings were conducted during the period 18 December 2002 until the day of the accident. PROBABLE CAUSE: During the investigation it was noted that the brake master cylinder was malfunctioning by not releasing the applied brake pressure back into the system and thereby allowing the brake shoes (drum brake system) to remain in the activated position.
