Narrative:
We were given clearance to fly 040 degree heading after hanki. I turned to 040 degree heading at intersection just prior to hanki. Problem occurred because of focusing on wrong DME for intersection. ATC queried us about our navigation track. We returned to correct course uneventfully. We should have discussed the turn location and briefed our intentions.

Title: HEADING TRACK POS DEV WHEN PIC TURNS TOO SOON DURING AMENDED CLRNC HEADING RTE CHANGE.
Narrative: WE WERE GIVEN CLRNC TO FLY 040 DEG HDG AFTER HANKI. I TURNED TO 040 DEG HDG AT INTXN JUST PRIOR TO HANKI. PROB OCCURRED BECAUSE OF FOCUSING ON WRONG DME FOR INTXN. ATC QUERIED US ABOUT OUR NAV TRACK. WE RETURNED TO CORRECT COURSE UNEVENTFULLY. WE SHOULD HAVE DISCUSSED THE TURN LOCATION AND BRIEFED OUR INTENTIONS.
