Iliamna, AK, US

On June 25, 2003, a DE Havilland DHC-2 (registration N930TG) was involved in an aviation accident near Iliamna, AK. Investigators recorded the probable cause as: The pilot's incorrect selection of the fuel selector valve position during takeoff which resulted in fuel starvation. A factor associated with the accident was inadequate transition training provided to the pilot by the company/operator management. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A solo commercial pilot inadvertently selected the fuel valve to off during takeoff from a remote lake in a DHC-2 floatplane, causing engine power loss and a forced landing on a gravel road.

Accident Overview

The pilot, who held a commercial certificate, was operating a float-equipped airplane on a solo flight from a remote lake. The pilot reported that this was his first assignment to fly the accident aircraft. During departure, the airplane climbed to approximately 30 feet above the water when the engine lost all power. The airplane subsequently descended and struck a gravel-covered road located at the departure end of the lake. The fuselage sustained substantial damage.

Fuel Valve Differences

The pilot stated that the accident airplane's main fuel valve was different from that of any other DHC-2 he had previously flown. Prior to takeoff, he placed the fuel valve in the "up" position, believing he had selected the center fuel tank.

Postaccident Findings

A postaccident inspection revealed that when the pilot placed the fuel valve in the "up" position, he inadvertently selected the "off" position. The pilot added that the operator did not inform him of the differences associated with the accident airplane's fuel valve.
