AIRCRAFT 1 PRELIMINARY REPORT


On January 26, 2000, at 1515 Alaska standard time, a Piper PA-32-301 airplane, N8004N, sustained substantial damage when it contacted a snow berm during landing on runway 01 at the Ekuk Airport, Ekuk, Alaska. The solo commercial pilot was not injured. The flight was operated by Peninsula Airways, Inc., of Anchorage, Alaska, under 14 CFR Part 135 as a cargo flight. The flight originated at 1505 from Clarks Point, Alaska. Visual meteorological conditions prevailed at the time of the accident, and a company VFR flight plan was in effect. During a telephone interview with the NTSB investigator-in-charge (IIC) on January 27, the pilot stated that the company flight scheduler told him the runway had been plowed, graded, and was open. The pilot related that the runway information was received from the village agent in Ekuk. The pilot said he made a low pass to inspect the runway, and it appeared open. He indicated the 1,200 feet long runway was plowed about 1,000 feet long, and about 40 feet wide, with the width varying. The pilot said that outside of the plowed area, there were six feet high snow berms. The airplane's wingtips were four feet high. The pilot stated the berms were "high enough for a Cessna 207, not quite high enough for Cherokee wings, and not visible from the air." The pilot told the IIC that during the landing roll, the left wing contacted a snow berm. No record was found of the pilot receiving a weather brief from the FAA Flight Service Station, or from commercial DUATS vendors. No Notices to Airmen (NOTAMS) were issued for runway conditions at Ekuk. Ekuk is a privately maintained runway, and is not supported by the State of Alaska. The Alaska Supplement contains a statement for the Ekuk Airport that "runways are not maintained during winter months." Inspection of the airplane by an FAA airworthiness inspector on February 2, revealed substantial damage to the left wing leading edge, and several leading edge ribs.

AIRCRAFT 1 FINAL REPORT


The commercial pilot was landing on a privately maintained, 1,200 feet long, snow-covered runway. The pilot told the NTSB investigator-in-charge that his flight scheduler told him the village agent had said the runway was plowed, graded, and open. He indicated that he made a low pass to inspect the runway, and it appeared open. During the landing roll, the left wing struck a snow berm and sustained substantial damage. The runway had been plowed about 1,000 feet long, and about 40 feet wide. The pilot indicated the berms on the side of the runway were about 6 feet high, and not visible from the air. The tips of the airplane's wings were about 4 feet high. The Alaska Supplement contains the statement for the airport that the 'runways are not maintained during winter months.'

AIRCRAFT 1 CAUSE REPORT


The pilot's selection of an unsuitable runway for landing. Factors associated with the accident were the inadequate runway maintenance by the runway maintenance personnel, snow berms, and insufficient runway condition information disseminated by the company dispatcher.
