NTSB narrative

THE AIRPLANE RAN OFF THE END OF THE RUNWAY AND DOWN AN EMBANKMENT AFTER THE LEFT BRAKE FAILED DURING LANDING. THE PILOT SAID HE HAD BRAKES ON THE RIGHT, BUT NOT THE LEFT. THE FAA EXAMINED THE AIRCRAFT AND FOUND THE LEFT BRAKE WORN TO THE POINT THAT THE PISTON EXTENDED BEYOND ITS NORMAL RANGE AND ALLOWED THE SEAL TO LEAK AND THE BRAKE TO FAIL. THEY ALSO SAID THE RIGHT BRAKE HAD FAILED IN A SIMILAR MANNER 4 HOURS PRIOR AND THE OWNER HAD INSTRUCTED THE REPAIR FACILITY TO ONLY REPLACE THE LININGS ON THE RIGHT SIDE.

Probable cause

A WORN OUT BRAKE ON THE LEFT MAIN GEAR. FACTORS RELATED TO THE ACCIDENT WERE: THE OWNER'S DECISION NOT TO REPAIR THE LEFT BRAKE AFTER THE RIGHT BRAKE HAD A SIMILAR FAILURE 4 HOURS EARLIER.

  • 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.
  • API snapshot SHA-256: 1f7eee1c0a344fe867dd1e73c57f98b963eaa5bf8af10c280ac2d4cd4afb5573; retrieved 2026-09-23T06:10:00.017Z.
