Narrative:
BEFORE THE ACCIDENT, WITNESSES OBSERVED THE AIRCRAFT CIRCLING IN A VALLEY BENEATH A LOW CLOUD LAYER & BELOW THE SURROUNDING HILLTOPS. THEY ESTIMATED THE CEILING WAS 400 FEET OBSCURED. TWO WITNESSES SAID THE AIRCRAFT ENTERED CLOUDS BEFORE IT CRASHED. A 3RD WITNESS, WHO WAS A PILOT, SAID THE AIRCRAFT WAS AT A VERY LOW ALTITUDE WHEN IT APPROACHED RISING/MOUNTAINOUS TERRAIN; HE SAID THE AIRCRAFT THEN ENTERED A STEEP CLIMBING TURN & STALLED AFTER MAKING 2 COMPLETE TURNS.

IMPACT OCCURRED IN A NOSE LOW, LEFT WING DOWN ATTITUDE. NO PREIMPACT MECHANICAL PROBLEM WAS FOUND. THE FAA HAD ISSUED THE PILOT A SPECIAL 3RD CLASS MEDICAL CERTIFICATE AFTER HE HAD QUINTUPLE HEART BYPASS SURGERY. HE WAS REPORTED TO HAVE GOTTEN "QUITE ANGRY' BEFORE THE FLIGHT", WHEN 2 PASSENGERS WERE LATE.

A PATHOLOGIST BELIEVED THE PILOT'S DEATH MAY HAVE BEEN DUE TO ARTERIOSCLEROTIC HEART DISEASE; HOWEVER, THIS WAS NOT VERIFIED. THE PILOT DID NOT HAVE AN INSTRUMENT RATING & NO RECORD OF A PRE-FLIGHT WEATHER BRIEFING WAS FOUND.

ALL FIVE PERSONS ON BOARD [PILOT AND FOUR PASSENGERS] WERE KILLED. THE REGISTRATION N6ET WAS CANCELLED BY THE FAA ON AUGUST 16 1990
