The NTSB's narrative final · quoted from the NTSB record
The pilot, an employee of the National Park Service, related he was returning to his position as a Park Ranger/Pilot after a three month furlough from the park service. The purpose of the accident flight was to regain proficiency in the Piper PA-18 airplane. The pilot said that during the landing roll on the fourth landing, he lost directional control of the airplane, and it ground looped to the left, which resulted in substantial damage to the airframe. Also, the pilot said he did not fly during his furlough, and that his total flight experience in the PA-18 airplane was approximately five hours.

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 ANC97TA045.
