Location: Aurora, Colorado Accident Number: CEN22LA308 Date & Time: July 3, 2022, 07:35 Local Registration: N184CB Aircraft: Vans RV6 Aircraft Damage: Substantial Defining Event: Loss of engine power (total) Injuries: 1 Minor, 1 None Flight Conducted Under: Part 91: General aviation - Personal
The pilot of the experimental airplane reported that the engine lost total power shortly after takeoff. The pilot decided to perform a forced landing straight ahead to a flat cornfield which resulted in substantial damage to the engine mount and lower fuselage.
Post accident examination of the airplane revealed a piece of black plastic material lodged in the carburetor throttle body. The foreign object debris (FOD) was similar to the material used with common trash bags. The pilot reported that he did not know where the FOD may have originated.
It is likely that the FOD blocked the engine’s air intake, which resulted in a total loss of engine power. The airplane’s carburetor heat valve provided heated air forward of the air filter; thus, the carburetor heat air flow did not bypass the air filter. While is it possible that the FOD may have been left in the carburetor heat system during previous maintenance work about 60 flight hours before the accident, the source of the FOD and when it was introduced could not be determined based on the available evidence. It is likely that the FOD, which was lodged in the carburetor throttle body, blocked air intake for the engine, which resulted in a total loss of engine power.
