2018-09-20 Igiugig, Alaska, United States Minor 1 aircraft Status: Completed

Aircraft involved

Probable cause & findings

The pilot’s selection of an empty fuel tank for takeoff, which resulted in fuel starvation and the subsequent total loss of engine power.

Factual narrative

The pilot of the float-equipped airplane reported that, during the initial climb after a water takeoff, about 200 ft, he turned right, and the engine lost power. He immediately switched fuel tanks and attempted to restart the engine to no avail. The airplane descended and struck trees, the right wing impacted terrain. The airplane sustained substantial damage to the right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported to the Federal Aviation Administration inspector that, during the initial climb, after the engine lost power, he noticed that the center tank, which was selected for takeoff, was empty. He added that passengers stated that the engine did regain power after switching tanks, but the airplane had already struck trees. The pilot reported as a recommendation to more closely follow checklists.
