DURING AN IFR ARRIVAL, THE AIRCRAFT WAS VECTORED FOR AN NDB RUNWAY 23 APPROACH TO THE WESTMORELAND COUNTY AIRPORT. AT THE NDB FINAL APPROACH FIX (8.1 MILES FROM THE RUNWAY), THE CREW TURNED INBOUND & CONTINUED TO THE AIRPORT. THEY CONTACTED THE TOWER & REPORTED OVER THE ILS OUTER MARKER (AN INTERMEDIATE POINT ON THE NDB FINAL APPROACH, 3.9 MILES FROM THE RUNWAY). THE TOWER ISSUED THE LOCAL LANDING ADVISORIES & CLEARED THE AIRCRAFT TO LAND.
MOMENTS AFTER THE CO-PILOT ADVISED THE CAPTAIN THAT THEY WERE 15 SECONDS FROM THE MISSED APPROACH POINT, THE AIRCRAFT COLLIDED WITH TREES. IMPACT OCCURRED 3.8 MILES SE OF THE AIRPORT AT THE MINIMUM DESCENT ALTITUDE (MDA) OF 1900 FEET AMSL.
AN EXAMINATION OF THE AIRCRAFT RECORDS INDICATED A RECURRING & CURRENT SQUAWK CONCERNING THE HSI SLAVING SYSTEM. JUST BEFORE BEGINNING THE APPROACH, THE LATROBE WIND HAD CHANGED FROM 230 DEGREES AT 4 KNOTS (A HEADWIND) TO A STRONG QUARTERING TAIL WIND.
DURING ARRIVAL THE CREW WERE ADVISED THE WIND WAS FROM 340 DEGREES AT 18 KNOTS. THEY HAD FIGURED THEIR TIMING TO THE MISSED APPROACH POINT BY USING A GROUND SPEED OF 120 KNOTS. EARLIER THAT DAY, THE SAME CREW & AIRCRAFT HAD TERMINATED THE SAME NDB APPROACH, 1 MILE EAST OF THE AIRPORT.
