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

The pilot reported that, shortly after takeoff, about 500 ft above the ground, both engines lost power. A forced landing was subsequently initiated to an open area. During the landing, the left wing collided with a wooden post and was substantially damaged. The pilot reported that there were no preacccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The airplane was fueled before the flight. The fueler reported that he incorrectly fueled the airplane with Jet A fuel instead of Avgas. He added that he did not notice the “Avgas only” label adjacent to the fuel port, and that he did not follow the company’s fueling checklist while fueling the accident airplane.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 WPR21LA342.
