The NTSB's narrative final · quoted from the NTSB record
The 15,563 hour commercial pilot successfully landed the single-engine helicopter on the offshore platform. Approximately 5 minutes after landing, the company dispatcher located on 43AA went outside and noticed the helicopter was still running, with the pilot leaning over the flight controls. A few minutes after landing, ground personnel at the platform found the pilot, sole occupant of the helicopter, incapacitated. The pilot was transported to a local hospital; however, resuscitation attempts were unsuccessful. The autopsy determined cause of death to be atherosclerotic cardiovascular disease with coronary insufficiency, and manner of death was considered to be natural.

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 DFW06IA145.
