What happened
The pilot was performing a normal short field landing using full flaps on a 2,200-foot runway. Following touchdown, the pilot retracted the flaps and attempted to apply the brakes. During this process, the left brake locked up while the right brake failed, resulting in a loss of directional control. The FAA reported that the aircraft touched down halfway down the runway, leaving 535 feet of skid marks before the aircraft exited the paved surface. During the excursion, the right main gear sheared off.
The investigation
The investigation noted that a mechanic had recently completed 16 hours of work on the aircraft, which included replacing both brake cylinders and bleeding the brake system. The pilot suggested that the accident might have been avoided if the brakes and related components had been inspected for leaking fixtures capable of allowing air to enter the system.
