Britten Norman Islander BN-2A-27, VP-MNI
After a normal landing the right brake failed. The pilot used the left brake to steer the aircraft into the grass to the left side of the runway to avoid the steep drop at its end. After departing the side of the runway the aircraft hit a raised embankment. The loss of right braking was attributed to trapped air in the hydraulic lines which was probably introduced during a right brake O-ring seal replacement prior to the accident flight. Following this repair work the right brakes had not been bled in accordance with the aircraft maintenance manual (AMM). The investigation also revealed that the aircraft manufacturer and some engineering organisations used a different brake bleeding procedure to that published in the AMM. One Safety Recommendation has been made.
