## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) AT AN ALTITUDE BETWEEN 200 AND 400 FEET AGL FOLLOWING A TOUCH AND GO LANDING, THE PILOT EXPERIENCED A ROUGH RUNNING ENGINE. FOLLOWING A THROTTLE ADJUSTMENT, THE ENGINE CONTINUED TO FALTER, PROMPTING THE PILOT TO MAKE THE DECISION TO EXECUTE AN EMERGENCY LANDING. THE EMERGENCY LANDING WAS MADE USING A SMALL RIGHT HAND TURN FROM RUNWAY HEADING (200 DEGREES) AND INTO A HAY FIELD. THE SELECTED HAY FIELD OFFERED INSUFFICIENT LANDING ROOM WITH THE AIRCRAFT COMING TO A REST IN SMALL PINE TREES AT THE FAR END OF THE FIELD. THE AIRCRAFT SUFFERED SUBSTANTIAL DAMAGE WITH NO INJURIES TO THE PILOT AND SOLE OCCUPANT OF THE AIRCRAFT. ALL 3 ROCKER SHAFT BOSSES IN CYLINDER #3 FAILED CAUSING A DEAD CYLINDER.
