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.

THE ENG FAILED AT 5,500 FT MSL. DURING AN EMERGENCY LANDING AT A 5,000 FT DIRT STRIP (UNDER CONSTRUCTION FOR PAVING), GEAR EXTENSION WAS DELAYED TO INCREASE GLIDE. THE RIGHT GEAR DID NOT HAVE TIME TO LOCK DOWN & RETRACTED DURING LANDING. INITIAL EXAM OF THE ENG REVEALED THAT THERE WAS NO VALVE ACTION IN THE CYLINDERS WHEN THE ENG WAS ROTATED ALTHOUGH BOTH MAGNETOS OPERATED NORMALLY. DISASSEMBLY CONFIRMED THAT THE GEAR SHAFT, P/N 620078, WHICH OPERATES THE TWO ENG CAMSHAFTS HAD SHEARED.
