What happened
The pilot reported encountering freezing rain during flight operations. Despite the application of carburetor heat, the engine ceased operating. The pilot initiated a forced landing to address the mechanical failure.
During the landing sequence, the right main gear collapsed. This structural failure resulted in damage to the right outboard wing panel.
The investigation
The pilot provided details regarding the cause of the engine failure. He reported that freezing rain had entered the carburetor air scoop. Ice formed on the air cleaner filter element, which restricted airflow to the carburetor.
Findings
The primary factor in this incident was the restriction of airflow due to ice accumulation. The carburetor icing prevented the engine from functioning correctly despite heat application.
