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 certified flight instructor (CFI) stated that the purpose of the flight was to practice glassy water landings in the float-equipped airplane. They overflew the practice area to check the condition of the river and the CFI stated that there were no obstacles or debris visible. Shortly after touchdown, both pilots reported hearing a loud bang and the airplane immediately nosed over. Both pilots exited the submerged airplane and sustained minor injuries. According to a Federal Aviation Administration inspector, the wreckage showed damage consistent with striking a submerged object. The airplane incurred substantial damage to its canopy, hull, and tail.

The certified flight instructor (CFI) stated that the purpose of the flight was to practice glassy water landings. After taking off from Spitfire Aerodrome, 7N7, they flew to the Philadelphia Seaplane Base practice area and overflew the area to check the condition of the river. The CFI stated that there were “no obstacles or debris visible.” Shortly after touchdown, both pilots reported hearing a loud bang, and the airplane immediately nosed over. Both pilots exited the submerged airplane and sustained minor injuries. According to the Federal Aviation Administration inspector-in-charge, the wreckage showed damage consistent with striking a submerged object and the landing was performed in the correct configuration. The airplane incurred substantial damage to its canopy, hull, and tail.
