On June 15, 1993, at 1330 Alaska daylight time, a wheel equipped Piper PA 18 150 airplane, N2571H, owned and operated by Wolf Trail Lodge, Inc., crashed during the landing rollout on a remote sod surfaced landing strip situated near a moose hunting camp. The commercial certificated pilot in command, the sole occupant, was not injured and the airplane sustained substantial damage. The business flight was being conducted under 14 CFR Part 91 at the time of the mishap for the purpose of making improvements to the camp. Visual meteorological conditions prevailed and a VFR flight plan had not been filed. The pilot in command reported to the NTSB investigator in charge by telephone on June 18, 1993, that this was his first seasonal landing at the strip, which he estimated to be approximately 750 feet in length. He elected to land on the first portion of the strip and reported that it was, "too rough". During the rollout, the plane traversed a soft area of humus and nosed over onto its back.
