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.

GAA18CA390

The pilot reported that, during short final, while approaching the runway threshold, he reduced the engine power to maintain glideslope, added full flaps, and applied a little left rudder to maintain the runway heading. Subsequently, the airplane sank and landed hard, and the nose landing gear collapsed. The airplane sustained substantial damage to both engine mounts, the right wing, tail, and rudder. The pilot also reported that, before the approach, an air traffic controller advised him that the wind at the destination airport was from 190° at 14 knots, gusting to 18 knots. The airport’s automated weather observation station reported that, about 10 minutes after the accident, the wind was from 200° at 14 knots. The airplane landed on runway 14. The Airport Facility Directory advised, "Steep drop off north of runway 14." The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
