NTSB narrative

In order to check the aircraft performance, the pilot decided not to fly the airplane until after conducting a 'highspeed taxi test.' During the test, the speed reached 40 knots and the pilot pulled the power to idle and applied the brakes. The brakes failed with 1,600 feet (the final 700 feet downgrade) of runway remaining and the airplane rolled beyond the departure end of the runway. Examination of the brake system by a mechanic, who had not performed previous work on the airplane, revealed the brake discs were worn beyond approved limits, and areas of the brake pads were worn down to the rivet heads. The wheel bearing grease was hard and all the bearings were dry and pitted. The right side brake cylinder was pitted and leaking. Dirt filled the brake master cylinders. The last annual inspection was completed on 6/10/96, and the airplane was returned to service by a mechanic with a FAA Inspection Authorization.

Probable cause

Inadequate maintenance by maintenance personnel resulting in inoperative brake system during an aborted takeoff. A factor was the downhill runway condition.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
