## Narrative

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

(-23) THE PILOT EXPERIENCED A ROUGH RUNNING ENGINE AND ELECTED TO MAKE AN EMERGENCY LANDING. HE LANDED DOWNWIND ON A ROAD SITUATED IN A PASTURE.  HE LOST CONTROL DURING BRAKING AND RAN OFF THE ROAD.  THE NOSE GEAR COLLAPSED AND THE AIRCRAFT FLIPPED OVER.  NO ONE WAS INJURED.  THE AIRCRAFT WAS SUBSTANTIALLY DAMAGED.  THE FIREWALL AND ENGINE MOUNT WAS BENT, R/H WING SPAR BENT, NOSE GEAR COLLAPSED AND THE FUSELAGE AND VERTICAL/HORIZONTAL STABLIZERS WERE TWISTED AND BENT.  THE PILOT WAS NOT CERTIFICATED NOR WAS THE AIRCRAFT REGISTERED. (.4) THE 900-HOUR PILOT LOST CONTROL OF THE AIRPLANE WHILE LANDING DOWNWIND ON A DIRT ROAD WITH A 15 KNOT TAILWIND.  THE PILOT REPORTED THAT THE ENGINE DEVELOPED A VIBRATION ACCOMPANIED BY A RISE IN CYLINDER HEAD TEMPERATURE.  THE PILOT ELECTED TO PERFORM A PRECAUTIONARY LANDING ON A WESTERLY HEADING ON A NEARBY DIRT ROAD TO INVESTIGATE THE SOURCE OF THE ENGINE PROBLEM.  THE PILOT WAS EXPECTING A CROSSWIND LANDING; HOWEVER, THE WIND SPEED AND DIRECTION WERE DIFFERENT THAN ANTICIPATED AND HE ENDED UP LANDING THE AIRPLANE WITH A TAILWIND. THE PILOT APPLIED THE BRAKES IMMEDIATELY AFTER TOUCHDOWN TO AVOID COLLIDING WITH A STEEL GATE.  SUBSEQUENTLY, THE AIRP LANE DRIFTED TO THE LEFT AND EXITED THE ROADWAY. THE NOSE LANDING GEAR ASSEMBLY COLLAPSED, AND THE AIRPLANE NOSED OVER AND CAME TO REST IN THE INVERTED POSITION.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
