Probable cause

The pilot's inadequate compensation for wind conditions. Factors in the accident were the presence of a tailwind, the pilot's inadvertent touchdown, and a short landing area bordered by high vegetation.

Analysis

The private certificated pilot was landing at his private airstrip, next to his cabin. The dirt airstrip, oriented southeast/northwest, is about 600 feet long, and 60 feet wide. The pilot said he overflew the strip several times. He selected full flaps, and began a landing approach toward the northwest. During the approach, a wind shift, producing a tailwind, carried the airplane past the pilot's intended landing spot, and the airplane inadvertently touched down. The pilot added full power to abort the landing. The airplane collided with brush at the end of the airstrip, and the airplane nosed over. The airplane received damage to the wings, fuselage, and tail.

Factual narrative

On June 24, 2000, about 1030 Alaska daylight time, a tundra tire equipped Piper PA-18 airplane, N78NR, sustained substantial damage during landing at a private airstrip, about 16 miles west of Skwentna, Alaska, at latitude 62 degrees, 05.69 minutes north, and longitude 151 degrees, 42.20 minutes west. The airplane was being operated as a visual flight rules (VFR) cross-country personal flight, when the accident occurred. The airplane was operated by the pilot. The private certificated pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The flight originated at the Birchwood airport, Chugiak, Alaska, about 0930.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on June 24, the pilot reported he was landing at his private airstrip, next to his cabin. The dirt airstrip, oriented southeast/northwest, is about 600 feet long, and 60 feet wide. The pilot said he overflew the strip several times. He selected full flaps, and began a landing approach toward the northwest. During the approach, a wind shift, producing a tailwind, carried the airplane past the pilot's intended landing spot, and the airplane inadvertently touched down. The pilot added full power to abort the landing. The airplane collided with brush at the end of the airstrip, and the airplane nosed over. The airplane received damage to the wings, fuselage, and tail.
