Aviation safety reports, made easier to study

NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.

The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.

The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

AFTER TAKING OFF FROM A BEACH WITH A HEAVY LOAD OF CLAMS, THE PILOT RADIOED THAT THE AIRPLANE'S CARGO DOOR HAD COME AJAR AND THE FLAPS WERE STUCK AT THE 10 DEGREE POSITION. HE CONTINUED THE FLIGHT TO THE HOME STRIP. AFTER A GO-AROUND AT THE 1900 FT HOME BASE STRIP, THE AIRPLANE WAS SEEN TO MAKE A STEEP LEFT, THEN A RIGHT TURN. THE AIRPLANE THEN DESCENDED FROM WITNESSES VIEW AND CRASHED INTO A WOODED AREA. THE LOWER LOCKING ROD OF THE AFT CARGO DOOR WAS FOUND TO BE BENT. TESTS SHOWED THE PILOT'S BLOOD HAD AN ALCOHOL LEVEL OF 342 MG/DL (0.342%) AND HIS URINE HAD AN ALCOHOL LEVEL OF 246 MG/DL (0.246%). ALSO, A METABOLITE OF NICOTINE AND DOXYLAMINE (AN OVER-THE-COUNTER ANTIHISTAMINE SLEEP-AID) WERE DETECTED IN THE PILOT'S BLOOD. A 5000 FT RUNWAY WAS LOCATED LESS THAN A MILE FROM THE HOME BASE STRIP.

NTSB Probable Cause

POOR JUDGEMENT OF THE PILOT, DUE TO IMPAIRMENT FROM CONSUMPTION OF ALCOHOL, AND HIS FAILURE TO MAINTAIN ADEQUATE AIRSPEED, WHILE MANEUVERING DURING AN ABORTED LANDING (GO-AROUND). FACTORS RELATED TO THE ACCIDENT WERE: THE OPEN CARGO DOOR, DISABLED FLAPS, AND THE PILOT'S DISTRACTION (DIVERTED ATTENTION).
