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.

ANC21LA101

The pilot reported that before landing on an unimproved airstrip, he tried to identify the wind direction using a ribbon located at the high point along the airstrip that was above the treetops. He also over flew the airstrip both ways at about 1,500 ft to verify what the ribbon was showing. During the landing, the airplane was not aligned with the airstrip, and the left main landing gear touched down first, which imposed a significate side load to the left main landing gear assembly. After the landing, the pilot noticed that he had landed with a quartering tailwind. The airplane sustained substantial damage to the fuselage and right-wing rear spar. The pilot reported no preimpact mechanical failures or malfunctions with the airplane that would have precluded normal operation.
