Aviation Accident Summary ANC94LA111

DEADHORSE, AK, USA

Aircraft #1

N4341Z

PIPER PA-18-150

Analysis

THE PILOT WAS CONDUCTING THE FLIGHT FOR THE PURPOSE OF GAME SPOTTING. THE PILOT LANDED THE AIRPLANE ABOUT 3/4THS DOWN A 800 FOOT LONG UNIMPROVED STRIP AND ELECTED TO GO-AROUND. DURING THE GO-AROUND, THE PLANE'S ENGINE EXPERIENCED A PARTIAL LOSS OF POWER, AND THE PILOT WAS FORCED TO LAND THE AIRPLANE ON A ROCK STREWN SURFACE. A SUBSEQUENT EXAMINATION OF THE PLANE'S ENGINE BY THE PILOT/OPERATOR DID NOT REVEAL THE CAUSE OF THE PARTIAL LOSS OF POWER.

Factual Information

On July 26, 1994, at 1300 Alaska daylight time, a tundra tire equipped Piper PA18-150 airplane, N4341Z, owned and operated by the pilot-in-command, collided with terrain near the Hula Hula River, approximately 120 miles east of Deadhorse, Alaska. The commercial certificated pilot, the sole occupant, was not injured and the airplane sustained substantial damage. The pleasure flight, conducted under 14 CFR Part 91, departed Deadhorse at approximately 0900 for the purpose of game spotting in the vicinity of the accident site. The pilot reported that calm winds and visual meteorological conditions prevailed at the time of the accident and that no flight plan was in effect. During a telephone conversation on the afternoon of July 27, 1994, the pilot told the NTSB investigator-in-charge that he landed the airplane about 3/4ths of the way down a 800ft. X 60ft. unimproved landing strip and he elected to go around. Just after lift off, the engine began missing and he was forced to land the plane on a rocky surface about 900 feet beyond the landing strip. A subsequent inspection of the airplane by the pilot/operator did not reveal the cause of the partial loss of power.

Probable Cause and Findings

THE PARTIAL LOSS OF ENGINE POWER FOR UNDETERMINED REASONS AND THE LACK OF SUITABLE TERRAIN FOR A FORCED LANDING.
