ANCHORAGE, AK, USA
N2389M
Piper PA-12
The pilot was on final approach to an off-airport landing area with a light, right 30 degree crosswind. The pilot said the airplane was configured with full flaps, and the indicated airspeed was between 30 and 35 miles per hour. A stand of trees was directly upwind, and next to, the runway threshold. On short final to land, the airplane settled, the wheels struck the river bank short of the runway, and the airplane nosed over.
On September 12, 1997, at 1545 Alaska daylight time, a Piper PA-12 airplane, N2389M, sustained substantial damage when it nosed over during landing at a gravel bar on the Theodore River, about 25 miles west of Anchorage, Alaska. The private certificated pilot and one passenger sustained minor injuries. The flight was conducted under 14 CFR Part 91, as a personal flight from Merrill Field in Anchorage, to the Theodore River, and returning. The flight departed Merrill Field at 1335. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed. The pilot reported he was landing to the west with an approximate 30 degree right crosswind of four knots. The airplane was just above touchdown, at an indicated airspeed of 30 to 35 miles per hour, with full flaps extended, when the airplane settled. He stated the airplane landed hard, the tail came up, and the prop struck the ground. The airplane nosed over onto its back. Photographs of the landing site reveal a stand of trees just to the right of the approach end of the landing area. The airplane was configured with 8.50 x 6 inch tires. Photographs of the gravel bar reveal two 6 inch wide gouges in the sand beginning below the lip of the river bank, and continuing onto the landing area. Between these gouges are four slash marks oriented approximately 45 degrees to the gouges, spaced about equally in the line of airplane travel.
The pilot's misjudgment of the touchdown point, which led to undershoot and the airplane nosing over.
