Read the full NTSB narrative

During cruise flight, the engine suddenly started to run rough and backfire periodically. The pilot attempted to troubleshoot the rough-running engine without success and decided to initiate a precautionary landing to a nearby road. During the landing roll, the airplane struck two road signs and a barbwire fence, substantially damaging the left and right wings. Examination of the engine revealed that the number three cylinder exhaust rocker arm was disconnected from the cylinder due to the rocker arm hold down nut backing off.
