The NTSB's narrative final · quoted from the NTSB record
The airplane was in cruise flight at 7,000 feet mean sea level, when the engine began to run rough and the oil pressure decreased. The pilot was unable to fly the airplane to the nearest airport and performed a forced landing to a field. During the landing, the airplane struck a ditch and came to rest upright, which resulted in substantial damage to the empennage. An annual inspection was completed on the airplane about 5 months, or 25 flight hours, prior to the accident; however, the pilot had recently changed the engine oil himself. Initial examination of the engine revealed that the oil drain tube remained attached to the oil quick-release drain plug, and oil was leaking down the side of the oil drain tube likely as a result of the quick-release oil drain plug not being properly secured. A subsequent teardown examination of the engine revealed that the No. 5 connecting rod failed due to lack of lubrication.

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 ERA10LA487.
