## Analysis

AT 1323 ADT, THE PLT RPRTD NEAR HINCHINBROOK ISLAND & REQUESTED CLEARANCE FOR AN NDB-A APCH TO THE CORDOVA MILE 13 ARPT. ABOUT 3 MIN LATER, CORDOVA FSS PROVIDED CLEARANCE FOR THE APCH 'FROM OVER HINCHINBROOK.'  RADAR DATA SHOWED THAT THE ACFT FLEW TO THE JOHNSTONE POINT (JOH) VOR, THEN BEGAN TRACKING ON A SSE HEADING TOWARD THE SUBSEQUENT ACCIDENT SITE. THE ACFT IMPACTED NEAR THE TOP OF A MTN AT AN ELEV OF ABOUT 2000 FT, APRX 10 MI SSE OF THE JOH VOR. FOR THE JOH TRANSITION (TO THE NDB-A APCH), THE PLT SHOULD HAVE TRACKED OUTBOUND FROM THE VOR FOR 15.5 MI ON A HEADING OF 083 DEG, WITH A MIN ALT OF 4000 FT, TO THE HINCHINBROOK INITIAL APCH FIX (IAP).
