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
WPR11CA259
The pilot reported that during his descent to land, he observed the windsock and made a mental note to maintain aileron correction for the crosswind. As the airplane reached about 35-40 feet above the runway, the pilot reduced power to idle and at an altitude of 2 feet he initiated the landing flare. The stall warning horn sounded and the nose of the airplane started to veer to the left. After the airplane touched down, the pilot applied right rudder and the airplane started to veer off to the right. The airplane exited the right side of the runway and struck a pipe that was protruding from the ground, substantially damaging the nose gear and firewall. The pilot reported no mechanical failures or malfunctions with the airframe or engine that would have precluded normal flight.
