## Narrative

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

THE FLIGHT DEPARTED, ABOUT 1515 EDT, FROM DILLANT-HOPKINS AIRPORT KEENE, NH (EEN), VFR AND WAS ON FLIGHT FOLLOWING, TO LONG ISLAND MACARTHUR AIRPORT NY, (ISP), AS PER PRELIMINARY ATC INFORMATION AND RADAR DATA, AND THE ONBOARD GARMIN HAND HELD GPS 396.  THE INFORMATION PROVIDED BY THE MASS STATE POLICE REPRESENTATIVE (MSPR) STATED THE PILOT INFORMED THEM THAT THE AIRPLANE HAD ENGINE PROBLEMS AT ABOUT 3,000 FEET. THE MORE EXPERIENCED PILOT SEATED IN THE RIGHT CENTER ROW SEAT(#4) SWAPPED POSITION WITH THE PASSENGER SEATED IN THE RIGHT FRONT SEAT(#2), TO ASSIST THE PILOT WITH THE IMMEDIATE PROBLEM. ABOUT TWO MINUTES FROM THE INITIAL ENGINE PROBLEM THE ENGINE LOST TOTAL POWER. AN OPENED FIELD WAS LOCATED AND THEY ELECTED TO LAND AT THAT FIELD. THEY OBSERVED THE TREES AND THE POWER LINES AT THE BEGINNING OF THE OPEN FIELD. THEY WERE ABLE TO CLEAR THE TREES BUT DID NOT HAVE ENOUGH ALTITUDE TO CLEAR THE TOP WIRE RUNNING BETWEEN TWO TOWERS IN FRONT OF THE TREES ALONG THEIR FLIGHT PATH. THE AIRPLANE CAUGHT ON THE TOP WIRE WHICH MADE THE AIRPLANE IMPACT THE GROUND. THE MSPR STATED THAT THERE WERE WITNESSES THAT OBSERVED THE AIRPLANE FLYING LOW, ONE HEARD THE ACCIDENT AIRPLANE'S ENGINE SPUTTERING, AND ANOTHER HEARD THE CRASH FROM THE NEARBY ROAD.
