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.

NTSB Number
WPR13CA235
The pilot reported that following an uneventful flight, he noted that the wind favored landing to the west, into the sun. During final approach to the runway, the pilot's view of the runway was obscured by the sun glare, however, he "thought I would get through the blind spot" and elected not to abort the landing. Subsequently, the right wing of the airplane struck a tree and the airplane impacted the ground, which resulted in structural damage to both the upper and lower left and right wings, and forward portion of the fuselage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. Official sunset was about 17 minutes after the time of the accident.
NTSB Probable Cause
The pilot's failure to maintain clearance from trees during final approach and his obscured vision due to the sun glare.
