The NTSB's narrative final · quoted from the NTSB record
The pilot was performing a touch-and-go landing. He extended the gear and checked gear down during approach, which he reported was normal. The pilot stated main gear touchdown was normal, but he had no memory of nose gear touchdown. He stated that 'the nose dropped below normal for landing roll-out' and he attempted to take off, but was too slow and the aircraft skidded to a stop in a nose-down position on the runway centerline. He stated, 'The landing gear appeared to be in a semi-retracted or collapsed position.' FAA inspectors noted abrasion damage to the main landing gear doors in a post-accident inspection, as well as nose gear overstress damage consistent with its being forcibly pushed back up into the nose wheel well. In a post-accident test, the main landing gear extended manually but the nose landing gear would not extend. The pilot reported he had not logged any pilot time in the 90 days before the accident.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number SEA99LA053.
