Narrative:

I (captain) copied clearance on through flight: 'cleared to sav raleigh 4 departure as filed, maintain X, squawk Y.' I read back the clearance. On climb out controller issued: 'maintain X heading, resume (unclear) 4 departure.' I assumed that I heard raleigh 4 departure with abc transition and turned to abc VOR. The controller issued me the turn back to my original heading and gave me vectors to def VOR. I then realized he gave a different SID, the tarr heel 4, not raleigh 4 departure. I am not aware of any conflict.

Original NASA ASRS Text

Title: BIZJET SMT ON DEP MADE WRONG CLRNC INTERP AND BEGAN TO FLY DIFFERENT SID FROM THAT ASSIGNED UNTIL CORRECTED BY DEP CTLR.

Narrative: I (CAPT) COPIED CLRNC ON THROUGH FLT: 'CLRED TO SAV RALEIGH 4 DEP AS FILED, MAINTAIN X, SQUAWK Y.' I READ BACK THE CLRNC. ON CLBOUT CTLR ISSUED: 'MAINTAIN X HDG, RESUME (UNCLEAR) 4 DEP.' I ASSUMED THAT I HEARD RALEIGH 4 DEP WITH ABC TRANSITION AND TURNED TO ABC VOR. THE CTLR ISSUED ME THE TURN BACK TO MY ORIGINAL HDG AND GAVE ME VECTORS TO DEF VOR. I THEN REALIZED HE GAVE A DIFFERENT SID, THE TARR HEEL 4, NOT RALEIGH 4 DEP. I AM NOT AWARE OF ANY CONFLICT.
