Narrative:

Cleared fll 8 departure thndr transition, departure on runway 9L, both captain and first officer had radios (VOR) set to fll VOR outbound course 335 degrees. Improperly intercepted fll 335 degree radial rather than SID clearance dolphin 335 degrees. Mia departure gave us a turn back to 270 degrees to intercept. No excuses. Only comment was captain and first officer had been on 5 consecutive all night 10 hour duty days. Fatigue a definite factor. Supplemental information from acn 401500: I left the vors tuned to fll instead of dhp for our departure. I noted rapid interception of the 335 degree radial which seemed strange to me. Mia departure queried us about the turn and directed us to resume a 270 degree heading until intercepting the dhp 335 degree radial. I estimate that we turned northwest about 8-10 mi early -- no I turned early.

IMPROPERLY INTERCEPTED FLL 335 DEG RADIAL RATHER THAN SID CLRNC DOLPHIN 335 DEGS. MIA DEP GAVE US A TURN BACK TO 270 DEGS TO INTERCEPT. NO EXCUSES. ONLY COMMENT WAS CAPT AND FO HAD BEEN ON 5 CONSECUTIVE ALL NIGHT 10 HR DUTY DAYS. FATIGUE A DEFINITE FACTOR. SUPPLEMENTAL INFO FROM ACN 401500: I LEFT THE VORS TUNED TO FLL INSTEAD OF DHP FOR OUR DEP. I NOTED RAPID INTERCEPTION OF THE 335 DEG RADIAL WHICH SEEMED STRANGE TO ME. MIA DEP QUERIED US ABOUT THE TURN AND DIRECTED US TO RESUME A 270 DEG HDG UNTIL INTERCEPTING THE DHP 335 DEG RADIAL. I ESTIMATE THAT WE TURNED NW ABOUT 8-10 MI EARLY -- NO I TURNED EARLY.
