Examination found the carburetor heat control inoperative; icing probability curves indicated moderate icing at cruise power.
Accident Overview
While conducting aerial fish spotting operations near Santa Cruz Island, California, the aircraft encountered a reduction in engine power while circling the area. As the aircraft approached the island, the engine experienced a complete loss of power, leading to a forced landing. During the landing, the aircraft nosed over.
Engine Examination
A post-accident examination of the engine revealed that the carburetor heat control was not functioning. The carburetor heat control is a critical component for preventing carburetor ice formation.
Carburetor Icing Conditions
According to carburetor icing probability curves, conditions at the time of the accident were conducive to moderate carburetor icing at cruise power settings and serious icing at glide power settings.
