Accident Overview
An aircraft crashed into the water of Sleetmute Slough following a series of low passes over boats. According to witness accounts, the pilot executed three passes at an estimated altitude of 5 to 10 feet above the water. After each pass, the aircraft would pull up in a steep climb, execute a 180-degree turn, and make another pass. Following the third pass, the aircraft pulled up, yawed to the left, and then crashed into the water in a nose-low, wings-level attitude.
Witness Accounts
Witnesses observed the pilot making repeated low passes over boats in the slough. The passes were estimated to be at 5 to 10 feet above the water surface.
