Incident Overview
A private pilot experienced an engine failure during initial climb following an annual inspection that included replacement of three cylinders. The aircraft had reached approximately 400 feet above ground level when the engine began to make unusual noises and subsequently stopped producing power.
Forced Landing
The pilot attempted to land on a road. However, the airplane landed short in a rough field. It slid for about 550 feet, crossed a ditch and an arroyo, then continued across the road before striking a dirt bank. The impact resulted in damage to the left wing spar, fuselage, engine mount, and firewall.
Postaccident Examination
A teardown of the engine revealed that the number two connecting rod had failed, causing the engine stoppage. The rod exhibited signs of under lubrication and overheating. The investigation found no evidence that the rod had been removed or disturbed during the maintenance performed prior to the flight.
