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.

EN ROUTE TO HIS DESTINATION, DURING LEVEL FLIGHT AT 9,000 FT, THE PILOT ADVISED ATC THAT HIS GYRO WAS INOPERATIVE. WHEN ASKED IF HE WOULD NEED ANY SPECIAL ASSISTANCE AT HIS DESTINATION, HE DECLINED. DURING THE ILS APPROACH HE WAS ISSUED A NEW VISIBILITY OF 1/4 MILE. HE SUBSEQUENTLY EXECUTED A MISSED APPROACH, AND WAS INSTRUCTED TO CLIMB AND MAINTAIN 2,500 FT FOR NO-GYRO VECTORS. THE AIRPLANE IMPACTED RISING TERRAIN 1/4 MILE FROM THE DEPARTURE END OF THE ILS RUNWAY. EXAM OF THE VACUUM PUMP REVEALED THAT THE ROTOR WAS BROKEN; ONE VANE WAS BROKEN, AND TWO PIECES WERE WEDGED IN ONE VANE SLOT. THE ROTOR ASSEMBLY WOULD NOT ROTATE. THE PILOT'S TOXICOLOGICAL RESULTS SHOWED 33.500 UG/ML OF ACETAMINOPHEN IN THE URINE, ALONG WITH DIPHENHYDRAMINE. THIS COMBINATION IS FOUND IN COMMON NON-PRESCRIPTION DRUGS SUCH AS 'BUFFRIN AF NITE TIME' AND 'EXCEDRIN P.M.'

NTSB Probable Cause

THE PILOT-IN-COMMAND'S FAILURE TO MAINTAIN A POSITIVE RATE OF CLIMB DURING A MISSED APPROACH. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: INOPERATIVE GYRO INSTRUMENTS DUE TO A BROKEN VACUUM PUMP, THE DARK NIGHT, ADVERSE WEATHER CONDITIONS, AND RISING TERRAIN.
