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 pilot reported that he overflew a remote airstrip, which was bounded by a lake on the approach end. He added that he circled back to land and that, during final approach, he encountered "glassy water and bright sun." Subsequently, the airplane landed short of the runway in the lake, sunk in more than 500 ft of water, and was not recovered. The Federal Aviation Administration aviation safety inspector who interviewed the pilot reported that he stated that the sun and the reflection off the lake gave him the impression that the airplane was higher than it was. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain an appropriate glidepath during the approach to the runway over glassy water and in glaring sun conditions.
