NTSB Narrative Summary Released at Completion of Accident

THE AIRCRAFT COLLIDED WITH MOUNTAINOUS TERRAIN WHILE EXECUTING AN INSTRUMENT MISSED APPROACH. THE RECORDED RADAR DATA SHOWED THAT THE ACFT WAS ABOUT 4 MILES PAST THE MISSED APPROACH POINT WHEN THE TURN WAS INITIATED. THE VOR RWY 6 APPROACH HAS A 620 FT MDA AND THE MISSED APPROACH POINT IS DEFINED AS 3.8 DME ON THE SCAGGS ISLAND VOR 050 RADIAL. THE RADAR DATA SHOWED THE ACFT CROSSED OVER THE AIRPORT DESCENDING THROUGH 1,800 FT MSL. THE LOWEST ALT ACHIEVED BY THE ACFT WAS 900 FT MSL, WHICH OCCURRED JUST BEFORE THE ACFT INITIATED THE MISSED APPROACH TURN.
