Burley, ID, USA

Aircraft #1

N566JH

Coltrin RV-6

Analysis

The pilot said he had entered downwind for landing and had pulled the throttle back to idle prior to turning base. While on base, he pushed the throttle forward to clear the engine; the engine did not respond. The pilot changed fuel tanks, checked boost pump, and manipulated the throttle with no engine response. He performed a forced landing to a potato field and the aircraft flipped inverted immediately after touchdown. The left horizontal stabilizer and the vertical stabilizer were bent and wrinkled. The pilot said that the engine's carburetor had been worked on within the year and he believes the power loss was due to the malfunctioning of the carburetor.
