## Narrative

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

ENGINE LOST POWER SHORTLY AFTER TAKEOFF AND AIRCRAFT MADE EMERGENCY LANDING ABOUT 3 MILES NORTH OF THE SPEARFISH, SD AIRPORT ON 4-4-13.  PILOT AND PASSENGER RECEIVED MINOR INJUIRES AND AIRCRAFT RECEIVED SUBSTANTIAL DAMAGE.  INSPECTOR DWA WENT TO THE SCENE ON 4-4 AND INSPECTORS DWA AND JBH INSPECTED THE AIRCRAFT ON 4-5 AFTER IT HAD BEEN MOVED TO A HANGAR IN SPEARFISH, SD.

ON THE LANDING ROLL, THE AIRCRAFT FLIPPED ONTO ITS BACK AND THE OCCUPANTS WERE ABLE TO EXIT THE AIRCRAFT AND WALK TO A FARMHOUSE BEFORE AN EMPLOYEE AT THE SPEARFISH AIRPORT ARRIVED AND TOOK THE PILOT TO THE HOSPITAL WITH HEAD CUTS AND A SHOULDER INJURY.

THE AIRCRAFT HAD A LOT OF DIRT AND OIL IN THE COWL, POSSIBLY BECAUSE OF OIL LEAKING WHEN THE ENGINE WAS UPSIDE DOWN AND THE AIRCRAFT SKIDDED SOME DISTANCE BEFORE COMING TO A STOP.  THE INSPECTORS NOTICED THAT THE COIL WIRE FROM THE COIL BLOCK WAS OFF, BUT COULDN'T DETERMINE IF IT WAS FROM THE ACCIDENT OR OCCURRED BEFORE.

THE PRIVATE PILOT AND HIS PASSENGER, A COMMERCIAL PILOT AND FLIGHT INSTRUCTOR STATED THE THE ENGINE JUST QUIT AND SWITCHING TO AUX COIL, AUX FUEL PUMP, AND ADJUSTING MIXTURE HAD NO AFFECT ON THE ENGINE AND IT WINDMILLED TO A STOP.
