The NTSB's narrative final · quoted from the NTSB record

The pilot stated that he was taxiing to the ramp, when the airplane's nose gear struck a storm drain, causing it to collapse and substantially damaging the wheel well. A postaccident examination of the airplane by the FAA revealed that the nose gear bolt, spacer and nut were missing. No other anomalies were noted. According to the pilot, the bolt had been replaced on September 1, 2004. In an FAA interview with the mechanic, it was discovered that the Beech maintenance procedures had not been followed while servicing the nose gear.

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 DEN04LA140.
