Company Policy; Human Factors; Procedure
A 300 hour maintenance inspection was completed on Company aircraft. During the preflight; a cotter pin was discovered to be missing from the right side pitch control linkage. I flew the aircraft during the time between the inspection and discovery and could possibly have flown it with the cotter pin missing.
Helicopter pilot reported cotter pin was found missing during pre-flight after 300 hour maintenance inspection was completed.
