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.

ABOUT 45 SECONDS AFTER TAKEOFF, THE AIRPLANE'S ENGINE LOST TOTAL POWER. THE PILOT MADE A FORCED LANDING, AND DURING THE APPROACH, THE AIRPLANE IMPACTED A TREE. POST ACCIDENT EXAMINATION OF THE AIRPLANE REVEALED THAT A PLASTIC FUEL LINE HAD BEEN SAFETY WIRED AND THE WIRE WAS OVER TORQUED, CAUSING THE FUEL LINE TO SPLIT. THERE WAS EVIDENCE THAT DURING INITIAL CLIMB FROM TAKE OFF, AIR ENTERED THE FUEL LINE, STARVING THE ENGINE OF FUEL. THE PILOT WAS OPERATING THE AIRPLANE UNDER 14 CFR PART 103 AS AN ULTRALIGHT AND DID NOT HOLD ANY FAA CERTIFICATES. THE POST ACCIDENT INVESTIGATION REVEALED THE AIRCRAFT WEIGHED OVER THE WEIGHT LIMITATION OF 254 POUNDS AS IMPOSED BY 14 CFR PART 103; THEREFORE, IT WAS DESIGNATED AN AIRPLANE.
