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.

PRIOR TO THE ACCIDENT FLIGHT, THE NON-CERTIFICATED STUDENT PILOT FUELED THE AIRPLANE FROM A 5-GALLON CONTAINER WITH AUTOMOTIVE FUEL. HE THEN INVITED A CERTIFICATED PILOT TO ACCOMPANY HIM ON A LOCAL AREA FLIGHT. WITNESSES OBSERVED THE AIRPLANE DEPART AND APPEARED TO CLIMB SLOWLY AT A SLOW AIRSPEED. DURING A LEFT TURN AFTER DEPARTURE, OTHER WITNESS HEARD THE ENGINE RUNNING ROUGH, SPUTTERING, AND THEN QUIT RUNNING. THE AIRPLANE THEN BANKED TO THE RIGHT AND DESCENDED IN A NEAR VERTICAL ATTITUDE, STRIKING A CEDAR TREE AND MOBILE HOME. THE AIRPLANE WAS CONSUMED BY A POST CRASH FIRE. EXAMINATION OF THE LEFT FUEL TANK THAT WAS NOT DAMAGED BY FIRE, REVEALED THE PRESENCE OF OVER A QUART OF WATER. THE INTERIOR FILLER NECK AND FUEL CAP HAD EVIDENCE OF RUST.
NTSB Probable Cause
A FAILURE OF THE STUDENT PILOT TO CONDUCT AN ADEQUATE PRE-FLIGHT INSPECTION TO REMOVE CONTAMINATED FUEL; A FAILURE TO MAINTAIN ADEQUATE AIRSPEED TO PREVENT AN INADVERTENT STALL. CONTRIBUTING TO THE ACCIDENT WAS AN INADEQUATE ANNUAL INSPECTION OF THE FUEL SYSTEM TO DETECT A LEAKING FUEL CAP, AND INADEQUATE SUPERVISION OF THE FLIGHT BY THE PILOT-INCOMMAND.
