Aviation Accident Summary ERA10CA467

Churchville, MD, USA

Aircraft #1

N2156K

LUSCOMBE 8A

Analysis

The pilot stated that the takeoff was normal until the airplane was about 50 feet above the ground, at which time he closed the carburetor heat and the engine lost power. The airplane’s landing gear then contacted top of a security fence beyond the end of the runway and the airplane bounced into a plowed field in a nose-down attitude. The pilot further stated that before he exited the airplane, he checked the fuel valve and found that it was not locked in the full forward position; rather, it was midway between the "ON" and "OFF" positions. The pilot said that in retrospect, he was not positive that he had placed the fuel valve in the "ON" position during his preflight inspection, and that this was the reason for the engine losing power on takeoff.
