A pilot landing on a remote gravel strip for fishing applied brakes and initiated a turn at taxi speed; the left main wheel contacted soft sand, causing the airplane to nose over. Subsequent inspection revealed brake cylinder contamination.

Incident Overview

A pilot was landing on a remote area intended for fishing. The landing area, approximately 1,000 feet long, was covered with gravel and oriented on a 090/270 degree heading. The pilot landed to the west. As the airplane neared the end of the landing area, the pilot applied the brakes and began a turn at taxi speed. During the turn, the left main wheel appeared to hit a soft portion of sand, and the airplane nosed over.

Mechanical Examination

On August 28, 1995, an airplane mechanic reported that the left wheel brake cylinder contained contamination. This contamination prevented the brake from releasing once pressure was applied. After being cleaned, the brake cylinder functioned properly.
