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.

ACCORDING TO WITNESSES, THE ACFT CROSSED A HIGHWAY AFTER TAKING OFF, ENTERED A LEFT TURN, DESCENDED & PULLED BACK UP, THEN WENT OUT OF CONTROL & CRASHED. ONE WITNESS INDICATED THAT THE ACFT ENTERED A SPIN PRIOR TO CRASHING. AN EXAM OF THE WRECKAGE SHOWED EVIDENCE THAT THE RIGHT ENG WAS PROVIDING POWER. THE LEFT PROP WAS FOUND IN A FEATHERED POSITION, BUT THE COCKPIT CONTROLS WERE NOT POSITIONED TO FEATHER THE LEFT PROP. AN EXAM OF THE LEFT ENG REVEALED THAT THE #5 CONNECTING ROD HAD FAILED FROM FATIGUE. THE FATIGUE HAD ORIGINATED IN AN AREA WHERE THE ROD HAD BEEN BENT. THERE WAS EVIDENCE OF PREVIOUS COLUMN BENDING OF THE ROD (POSSIBLY FROM A HYDROSTATIC LOCK). THE LEFT PRIMER WAS FOUND BROKEN.
