The NTSB's narrative final · quoted from the NTSB record
THE COMMERCIAL PILOT ATTEMPTED TO TAKEOFF FROM A ROUGH AND SOFT OFF-AIRPORT SITE IN RURAL ALASKA. DURING THE TAKEOFF ROLL, THE AIRPLANE'S MAIN LANDING GEAR ENCOUNTERED AN EXCEPTIONALLY SOFT SPOT, CAUSING THE AIRPLANE TO NOSE OVER. THE PILOT STATED THAT THE ACCIDENT COULD HAVE BEEN AVOIDED IF HE HAD SELECTED HIS LANDING SITE MORE CAREFULLY, AND HAD STAYED AWAY FROM SUCH SOFT TERRAIN.

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 ANC88LA131.
