## Narrative

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

(.4)THE SUBARU LEGACY POWERED CESSNA 150 EXPERIENCED A PARTIAL LOSS OF ENGINE POWER ABOUT 30 MINUTES AFTER TAKEOFF. SOON THEREAFTER, THE ENGINE LOST ALL POWER, AND THE PILOT EXECUTED A FORCED LANDING IN A NEARBY FIELD.  ALTHOUGH THE TOUCHDOWN WAS SUCCESSFUL, THE NOSE GEAR DUG INTO THE SOFT TERRAIN AS THE PILOT APPLIED BRAKES TO STOP SHORT OF AN UPCOMING DITCH.  AFTER THE NOSE GEAR DUG INTO THE TERRAIN, THE AIRCRAFT FLIPPED OVER ONTO ITS BACK.  A TEARDOWN OF THE ENGINE REVEALED THAT THE HEAD HAD FRACTURED OFF ONE OF THE EXHAUST VALVES IN THE FORWARD LEFT CYLINDER, RESULTING IN THE DESTRUCTION OF THE PISTON.                                                             (-23)AIRCRAFT EXPERIENCE A TOTAL LOSS OF POWER DUE TO A MECHANICAL MALFUNCTION OF THE ENGINE.  MR. HOFFMANN SELECTED A FIELD AND PERFORMED EN EMERGENCY LANDING.  AFTER LANDING, THE NOSE WHEEL SANK INTO WET SOIL, AND THE AIRPLANE OVERTURNED.  THERE WERE NO INJURIES.
