NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

THE PILOT WAS CLEARED FOR AN INSTRUMENT LANDING SYSTEM APPROACH BY THE CONTROL TOWER. THE REPORTED WEATHER CONDITIONS INCLUDED A INDEFINITE CEILING OF 100 FEET AND ONE HALF MILE VISIBILITY WITH FOG. DURING THE APPROACH, THE AIRSPEED, GLIDEPATH, RATE OF DESCENT, AND POSITION RELATIVE TO THE GLIDESLOPE AND LOCALIZER WERE NOT STABILIZED. THE AIRPLANE IMPACTED TERRAIN ABOUT ONE HALF MILE FROM THE END OF THE RUNWAY. THE PUBLISHED DECISION HEIGHT FOR THE APPROACH IS 200 FEET ABOVE THE GROUND. ACCORDING TO AN INSPECTOR WITH THE MASSACHUSETTS AERONAUTICS COMMISSION, THE PRIVATE PILOT WAS PAID TWO HUNDRED DOLLARS TO FLY THE TWO PASSENGERS, AND HE HAD BEEN PAID TO FLY THE SAME ROUTE AT LEAST TEN TIMES BEFORE THE ACCIDENT FLIGHT.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE PILOTS'S LACK OF REGARD FOR THE PUBLISHED DECISION HEIGHT OF THE APPROACH AND HIS DECISION NOT TO EXECUTE A MISSED APPROACH. FACTORS CONTRIBUTING TO THE ACCIDENT INCLUDE THE PILOT'S FAILURE TO ATTAIN THE PROPER GLIDEPATH AND DESCENT RATE DURING THE APPROACH, THE PILOT'S POOR IN FLIGHT DECISION TO CONTINUE THE APPROACH, WEATHER CONDITIONS WHICH WERE BELOW APPROACH MINIMUMS, DARK NIGHT LIGHTING CONDITIONS, AND SELF INDUCED PRESSURE BY THE PILOT TO COMPLETE THE FLIGHT.
