An aircraft experienced engine failure at approximately 1,400 feet MSL during initial climb, resulting in a forced landing in a cornfield. Investigation revealed a broken carburetor heat linkage.

What happened

During the initial takeoff climb phase, the engine ceased operation while the aircraft was at an altitude of approximately 1,400 feet mean sea level (MSL). The pilot attempted to regain power but was unsuccessful. Consequently, the aircraft nosed over during a forced landing in a cornfield.

The investigation

A post-accident examination of the engine revealed that the carburetor heat linkage on the control rod was broken. Following this discovery, the engine was started and operated without interruption, indicating that the mechanical failure was isolated to the linkage component rather than internal engine damage.

Probable cause

The pilot's inability to maintain power during takeoff due to a broken carburetor heat linkage on the control rod.
