The NTSB's narrative for the Great Lakes 2T-1A-2 final · quoted from the NTSB record

The commercial pilot of the tailwheel-equipped biplane was in the runup pad adjacent to the taxiway, had just completed his pre takeoff checks, and was attempted to taxi into position to hold for takeoff. The private pilot of a low-wing airplane was already stopped at the hold short line of the departure runway. As the biplane pilot taxied out of the runup pad he performed several s-turn maneuvers and looked out the side of the cockpit to increase his limited forward visibility, but did not see the low-wing airplane. The biplane impacted the low-wing airplane, striking the right wing and aileron with the operating propeller, which resulted in substantial damage to the low-wing airplane.

The complete narrative as the NTSB published it. The NTSB's docket holds the report as a PDF and any photographs, statements and other documents from the investigation.

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 ERA22LA119.
