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

The pilot entered the traffic pattern for a visual approach to the runway. He reported that the final approach descent was faster than he anticipated due to the high humidity and high density altitude. He added more engine power to arrest the descent rate, but the airplane landed short of the runway in a wet, grass field and came to rest upright. A postaccident examination of the airplane revealed that the main landing gear separated and the aft carry-through wing spar was bent. The pilot reported there were no mechanical anomalies with the airplane that would have precluded normal operation.

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 CEN11CA411.
