On August 1, 1995, about 1600 Alaska daylight time, a wheel equipped Piper PA-22-150, N7597D, crashed during takeoff from a remote area at the mouth of the Kustatan River, about 18 miles west of Nikiski, Alaska. The airplane was being operated as a visual flight rules (VFR) cross-country personal flight to Anchorage, Alaska, when the accident occurred. The airplane, operated by the pilot, received substantial damage. The certificated private pilot and 3 passengers were not injured. Visual meteorological conditions prevailed. The pilot reported that he landed earlier in the day in soft, muddy terrain to fish in the nearby Kustatan River. He had landed in the area on previous occasions. The pilot indicated that during the takeoff run, the airplane accelerated to 60 MPH but the liftoff was impeded by high grass. The pilot aborted the takeoff and the airplane traveled beyond the intended takeoff area. The nose gear then failed and the airplane nosed over. The airplane received damage to the nose gear and empennage. The pilot reported that light rain was falling in the area of the accident.
