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 ENG CONTINUED TO RUN ROUGH AND LOSE PWR AND THE PLT RETURNED TO THE ARPT. THE ACFT WAS AT ABOUT 200 FT UPON ARRIVAL AT THE ARPT AND THE PLT ATTEMPTED TO ALIGN WITH RWY 16, WHICH WAS THE DOWNWIND RWY. UPON APPROACHING RWY 16 THE PLT NOTED ANOTHER ACFT LANDING IN THE OPPOSITE DIRECTION AND TURNED TO PARALLEL THE RWY. THE ACFT CONTINUED TO DESCEND DUE TO LOW PWR AND STALLED AND CRASHED FROM ABOUT 20 FT AGL NEAR MIDFIELD. EXAMINATION OF THE WRECKAGE REVEALED THAT THE MIXTURE CONTROL WAS NOT IN THE FULL IN POSITION. FURTHER EXAMINATION OF THE WRECKAGE AND A TEST RUN OF THE ENG DID NOT REVEAL EVIDENCE OF A PRE-ACCIDENT MECHANICAL FAILURE OR DEFICIENCY.
