SALINAS, CA, USA
N186SE
North American F-86
During an air show, the pilot made several uneventful flybys, then landed near the beginning of the runway. During rollout, the pilot noted a hydraulic brake system failure. Unable to stop with only unboosted brakes, the airplane overran the departure end of the 5,005 foot runway and collided with a fence and rough terrain. Investigation revealed the engine driven #3 system auxiliary hydraulic boost pump had failed internally. Metal particles were found in its screen.
On October 6, 1996, at 1145 hours Pacific daylight time, a North American F-86, N186SE, landed in the touchdown zone on runway 26 during an air show at the Salinas Municipal Airport, Salinas, California. The pilot reported that during rollout he experienced hydraulic brake system failure. The airplane overran the departure end of the 5,005-foot-long runway and collided with a fence and rough terrain which resulted in substantial airframe damage. The airline transport pilot was not injured. Visual meteorological conditions prevailed. The flight originated from Salinas at 1135. According to the pilot, during the flight he had performed several flybys without incident. On final approach the airplane lost all utility hydraulic pressure. During rollout he shut down, but was unable to stop with the unboosted brakes. The FAA coordinator reported its investigation revealed that the engine driven No. 3 system auxiliary hydraulic boost pump internally failed. Metal particles were found in its screen.
an internal failure of a hydraulic pump, which resulted in contamination in the hydraulic system and subsequent loss of the braking system. Factors related to the accident included the proximity of a fence and rough/uneven terrain adjacent to the runway.
