NTSB narrative

THE PLT SAID HE MADE A NORMAL LDG. DURING LDG ROLL THE LEFT BRAKE WOULD NOT RESPOND TO PEDAL APPLICATION. THE PLT ERRORED BY INCORRECTLY FEATHERING BOTH PROPS. THE A/C WENT OFF THE ENG OF R/W AND STRUCK A FENCE. EXAMINATION OF THE BRAKE SYSTEM REVEALED A BRAKE PUCK WAS MISSING. A MISSING PUCK WOULD CAUSE POOR BRAKING ACTION.

  • 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.
