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.

DURING CRUISE FLT, THE PLT REPORTED THAT THE RT ENG COWLING PARTIALLY SEPARATED & THE LT FWD CYLINDER OF THAT ENG SEPARATED, FOLLOWED BY AN ENG COMPARTMENT FIRE. HE ATTEMPTED TO FEATHER THE PROPELLER BUT WAS UNABLE. HE INITIATED A DESCENT TO EXTINGUISH THE FIRE & WAS SUCCESSFUL BUT AFTER LEVELING OFF, WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL. HE DITCHED THE AIRPLANE & BOTH HE & THE PAX EXITED THE ACFT. THE PLT DRAGGED THE SERIOUSLY INJURED PAX WITH HIM TO A NEARBY ISLAND WHERE THEY WERE RESCUED THE FOLLOWING DAY. THE ACFT WAS NOT RECOVERED; THEREFORE, NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE SEPARATION OF THE CYLINDER. REVIEW OF THE ACFT LOGBOOK INDICATES THAT ON 8/27/91, THE NO.5 CYLINDER OF THE RT ENG WAS REMOVED & REPLACED. ALSO, THE NO. 1 CYLINDER WAS REMOVED & REINSTALLED FOLLOWING REPAIR. THERE WERE NO FURTHER ENTRIES IN THE ACFT LOGBOOK REGARDING CYLINDER REMOVAL OR REPLACEMENT TO THE RT ENG.
