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, during the takeoff roll, the airplane encountered a wind gust and veered left off the runway centerline. He added that the airplane became airborne but that he did not have "enough time" to avoid a parked helicopter. Subsequently, the left wing impacted the helicopter. He then reduced the engine power, and the airplane landed without further incident. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system about 5 nautical miles from the accident site reported that, about the time of the accident, the wind was from 230° at 12 knots, gusting to 17 knots. The pilot was departing on runway 22.
