The NTSB's narrative final · quoted from the NTSB record

THE PILOT OF THE PIPER PA28-236 WAS CLEARED FOR AN NDB APPROACH AND RADAR SERVICE WAS TERMINATED. THE AIRCRAFT WAS SEEN BY SEVERAL WITNESSES FLYING VERY LOW, ABOUT 1 MILE WEST OF THE INBOUND PUBLISHED APPROACH COURSE ACCORDING TO WITNESSES THE WEATHER CONDITIONS AT THE TIME OF THE ACCIDENT WERE POOR WITH LOW VISIBILITY, DUE TO FOG AND DRIZZLE. THE AIRPORT IS EQUIPPED WITH RUNWAY STROBE LIGHTS, BUT THERE WERE NO WITNESSES THAT COULD REMEMBER IF THEY WERE ON OR OFF AT THE TIME OF THE ACCIDENT. WHEN LAST SEEN THE AIRCRAFT WAS FLYING LOW PERPENDICULAR (EAST) TO THE INBOUND COURSE, IT THEN TURNED LEFT, FLYING AWAY FROM THE AIRPORT.
