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.

ON THE FIRST FLIGHT OF AN EXPERIMENTAL HOMEBUILT AIRCRAFT, THE PILOT TOOK OFF WITH WHAT NUMEROUS WITNESSES DESCRIBED AS A ROUGH RUNNING ENGINE. THE FLIGHT PATH AFTER TAKEOFF WAS A PATTERN FOR A RETURN TO LANDING FLOWN AT LESS THAN NORMAL PATTERN ALTITUDE. DURING THE TURN TO FINAL, THE AIRCRAFT WAS OBSERVED TO STALL AND ROLL AT APPROXIMATELY 100 FEET ABOVE GROUND LEVEL FOLLOWED BY A STEEP IMPACT. THE AIRCRAFT WAS EXTENSIVELY DAMAGED BY IMPACT AND GROUND FIRE. NO REASON WAS FOUND FOR THE APPARENT LOST OF POWER.
NTSB Probable Cause
PARTIAL LOSS OF ENGINE POWER FOR AN UNDETERMINED REASON, IMPROPER PLANNING/DECISION BY THE PILOT, AND THE PILOT'S FAILURE TO MAINTAIN ADEQUATE AIRSPEED, WHICH RESULTED IN AN INADVERTENT STALL.
