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 PLT HAD RECENTLY PURCHASED THE ACFT. WHILE ON A X-COUNTRY TRIP, HE LANDED AT AN ARPT WITH AN ELEVATION OF 4363 FT & REFUELED. WHEN HE WAS TAKING OFF, THE DENSITY ALT WAS APRX 7089 FT & THE ACFT WAS NEAR ITS MAX GROSS WT LIMIT. SHORTLY AFTER LIFT-OFF, THE PLT RADIOED THAT HE 'WAS HAVING A LITTLE TROUBLE GAINING ALT.' HE THEN STATED THAT THE ACFT HAD PROBLEMS & HE DIDN'T KNOW WHAT THEY WERE. A STALL WARNING HORN WAS OPERATING AS HE WAS TRANSMITTING. THE ACFT SUBSEQUENTLY CRASHED IN A NOSE DOWN, LEFT WING LOW ATTITUDE WHILE AT A RELATIVELY LOW AIRSPEED. AN EXAM OF THE ENG, ACFT SYSTEMS & FLT CONTROLS REVEALED NO EVIDENCE OF A FAILURE OR MALFUNCTION. ACCORDING TO A LYCOMING REP, THE ENG WOULD HAVE BEEN PRODUCING A MIXIMUM OF 79% OF ITS RATED POWER AT A DENSITY ALT OF 7089 FT.
