Aircraft Accident/Incident Report

Watkins, Colorado 80137
Wednesday, April 11, 2007 14:30 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot had been practicing touch-and-go landings. On his final landing, the airplane swerved to the right and the right wing struck the ground, bending the spar. The airplane then departed the runway. According to the FAA airworthiness inspector who examined the airplane, the right brake caliper assembly showed "severely worn shoes with uneven wear." The inspector surmised that when the pilot applied the brakes, the uneven brake shoe wear "caused the caliper pins to engage misaligned, contacting the rotor, locking and shearing the caliper assembly."

NTSB Probable Cause Narrative

A total failure during landing roll of the right brake caused by severely worn shoes, causing the caliper pins to engaged misaligned. A contributing factor was the pilot's inability to maintain directional control.
