Aviation Accident Summary ANC96LA136

SKWENTNA, AK, USA

Aircraft #1

N4726T

Maule M-4

Analysis

The pilot reported he was landing his airplane at a remote gravel bar. He said he touched down further down the gravel bar then he intended, and then realized there was a depression just ahead. He attempted to take off, but his hand was knocked off the throttle by the rough terrain. The airplane entered the depression, the main landing gear dug in, and the airplane nosed over.

Factual Information

On September 2, 1996, about 1700 Alaska daylight time, a wheel equipped Maule M-4 airplane, N4726T, sustained substantial damage when it nosed over while landing on a gravel bar located approximately 50 miles west of Skwentna, Alaska. The private pilot and sole passenger aboard were not injured. The 14 CFR Part 91 flight operated in visual meteorological conditions. The flight last departed Palmer, Alaska, about 1520, and the destination was the gravel bar. During a telephone conversation with the NTSB investigator-in-charge on September 5, the pilot reported that after touchdown on the gravel bar, he realized that he had touched down farther down the gravel bar than he wanted to. He said he tried to abort the landing, but as he reached for the throttle to increase engine power, the airplane struck something on the gravel bar. The pilot said his hand was knocked away from the throttle by the impact. The pilot was unable to maintain directional control, and the airplane entered a depression in the gravel bar. The left main landing gear wheel subsequently dug into the ground, and the airplane nosed over.

Probable Cause and Findings

The pilot's selection of an unsuitable landing site. A factor associated with the accident was the rough and uneven terrain.
