Probable cause

Failure of the pilot to maintain proper runway alignment during an aborted landing. Related factors were: a false airspeed indication, the pilot's lack of familiarity with the aircraft, his improper use of carburetor heat, his diverted attention, and the fence.

Analysis

The plt flew from sacramento to Rio Linda, lincoln, marysville, then back to Rio Linda. As he was depg marysville, he noticed an improper indcn of the airspeed indicator (which was reading too low). He assumed a bug had blocked the pitot opening & continued to Rio Linda. On arrival, the acft bounced drg an attempted 'wheel landing.' The plt believed the airspeed may have been too high (or too low), causing the acft to bounce. He continued the landing, but the acft bouncedagain, so he initiated a go-around. Drg the go-around, he became distracted by his inability to locate & turn off the carburetor heat. As he was looking for the carburetor heat control, the acft angled off the rwy to the right & headed toward the wind tee & a fence which paralleled the rwy. The plt avoided the wind tee, but the acft's right wing & tailwheel struck the fence.
