NTSB narrative

THE ACFT DRAGGED THE RIGHT WING TIP TANK AND RUPTURED IT AFTER THE PASSENGER DOOR OPENED DURING TAKEOFF. DURING THE ABORTED TAKEOFF THE ACFT OSCILLATED RIGHT, LEFT AND RIGHT BEFORE MAKING GROUND CONTACT ON THE RIGHT WING. THE HIGHEST ALT ATTAINED WAS ABOUT 100 FT AGL. BEFORE TAKEOFF A PUROLATOR CARGO HANDLER INTERRUPTED THE CAPTAIN CLOSING THE DOOR TO GIVE HIM A PACKAGE. THE CAPT WENT TO SECURE THIS PACKAGE AND THE CARGO HANDLER CLOSED THE DOOR. AFTER THE CAPT WAS IN HIS SEAT HE AND THE CO-PILOT FAILED TO NOTE THE RED DOOR WARNING LIGHT MENTALLY REGARDING IT AS A MALFUNCTIONING FUEL WARNING EVEN THOUGH THESE LIGHTS ARE SEPARATED BY 3 OTHER LIGHTS. DURING THE TAKEOFF AT ABOUT 110 KTS THE DOOR OPENED AND THE ABORT COMMENCED. THE CARGO HANDLER WAS INTERVIEWED AND ADMITTED CLOSING THE DOOR BUT SAID HE NEVER LATCHED THE DOOR SINCE IT REQUIRES A KEY TO ACTIVATE IT. THIS WAS ALWAYS DONE BY THE CREW.

  • 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: fdf50a63b388be01abb5baa079790812e4bc2647ec51a5b91a0e2da4d851896f; retrieved 2026-09-18T20:58:03.871Z.
