## Narrative

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

AIRCRAFT WAS ON 20 MINUTE LOCAL SIGHTSEEING FLIGHT.  AFTER TAKE-OFF, PROCEEDED TO TWO LOVERS POINT, HELD FOR OTHER TRAFFIC OVER TUMON BAY FOR @ 5 MINUTES, THEN PROCEEDED TO CHAMORRO VILLAGE ON THE WAY TO CAMEL ROCK.  THE PILOT NOTICED SPARKS COMING FROM THE LEFT SIDE  AND SMOKE WAS FILLING UP THE CABIN.  THE PILOT OPENED THE LEFT WINDOW TO LET THE SMOKE OUT, THERE WAS NO FIRE BUT THE FUMES CONTINUED TO FILL THE CABIN.  SHORTLY AFTER THAT, THE ENGINE LOST POWER AND THE AIRPLANE STARTED TO SHAKE VIOLENTLY.  ALTITUDE WAS @1,000 FT ASL.  PILOT MADE A MAY-DAY CALL AND HEADED DIRECT TO GUAM AIRPORT.  PILOT FOLLOWED EMERGENCY ENGINE OUT PROCEDURES TO NO AVAIL.  PILOT REALIZED HE WAS TOO LOW TO MAKE THE RUNWAYS AT GUAM AIRPORT SO LANDED IN THE GRASS AREA SHORT OF RUNWAY 6L AND 6R.  JUST PRIOR TO TOUCHDOWN, THE PILOT SAW AN AIRPORT PERMETER FENCE IN THE ROLL OUT ZONE AND SO TURNED TO THE LEFT TO AVOID THE FENCE.

IN REVIEWING PHOTOS, THE LEFT MAIN LANDING GEAR HAS DAMAGE (BENT FROM NORMAL POSITION), THE NOSE LANDING WAS SHEARED OFF AND THERE IS SUBSTANTIAL DAMAGE TO THE FIREWALL.

THE LANDING AREA IS A IN A SHALLOW GULLY, WITH THE REMAINS OF CONCRETE FOUNDATIONS SURROUNDED BY A SECURITY FENCE CONSISTING OF CONCRETE VERTICAL POSTS, STEEL CABLES AND CHAIN-LINK FENCE.

PILOT STATED HE CHECKED OIL PRIOR TO THIS FLIGHT AND HAD 4 QUARTS.  THE AIRCRAFT OWNER STATED HE CHECK THE OIL AT THE ACCIDENT SITE AND IT WAS AT ZERO (0).  THE OWNER FURTHER STATED THAT IT APPEARED THERE WAS AN OIL LEAK AT #4 CYLINDER.

THE CAUSE OF  SPARKS, SMOKE AND ENGINE LOSS OF POWER IS UNDETERMINED.
