Narrative:

While flying the bowie 5 arrival into dfw, a chain of errors developed. We were cleared direct to bambe intersection and given a descent. I reset the GPS (which was being used for primary navigation) then reset the #1 VOR/HSI. I asked my co-captain to tune his VOR/HSI to the STAR. I then noticed that the altitude preselect had not been reset to our new assigned altitude. I mentioned the error to my co-captain, then reset the altitude preselect. At the same time, regional approach gave us 3 new items. A descent, a heading change to be executed at siler intersection, and a frequency change. I began the descent and turned to reintercept the STAR (as assigned), noticed that the altitude preselect had not been changed (for the second time). I asked the co-captain to reset the altitude preselect, then mentioned that he had not changed frequencys. I then asked him to verify the assigned heading after siler (I heard 180 degrees, while 170 degrees is published). His reply 'split the difference. Fly 175 degrees.' while trying to resolve this confusion, I flew past siler and did not make the heading change or reduce speed as published. ATC asked our speed, our reply 240 KTS. ATC then said '210 degrees is published and you missed your turn, turn right to 210 degrees, descend and maintain 3000 ft.' I immediately complied and reduced speed. The rest of the flight was uneventful. Contributing factors: flight deck workload in the approach control area. Poor CRM. Series of 3 commands at once from ATC. I was so busy monitoring the co-captain's actions and inactions (trying to preclude an altitude bust), that I did not do my job, ie, fly the STAR.

Title: CRM BREAKS DOWN FOR CREW ON APCH TO DFW, TX, RESULTING IN ERRORS IN BOTH ALT AND HDG ON THE ARR.

Narrative: WHILE FLYING THE BOWIE 5 ARR INTO DFW, A CHAIN OF ERRORS DEVELOPED. WE WERE CLRED DIRECT TO BAMBE INTXN AND GIVEN A DSCNT. I RESET THE GPS (WHICH WAS BEING USED FOR PRIMARY NAV) THEN RESET THE #1 VOR/HSI. I ASKED MY CO-CAPT TO TUNE HIS VOR/HSI TO THE STAR. I THEN NOTICED THAT THE ALT PRESELECT HAD NOT BEEN RESET TO OUR NEW ASSIGNED ALT. I MENTIONED THE ERROR TO MY CO-CAPT, THEN RESET THE ALT PRESELECT. AT THE SAME TIME, REGIONAL APCH GAVE US 3 NEW ITEMS. A DSCNT, A HDG CHANGE TO BE EXECUTED AT SILER INTXN, AND A FREQ CHANGE. I BEGAN THE DSCNT AND TURNED TO REINTERCEPT THE STAR (AS ASSIGNED), NOTICED THAT THE ALT PRESELECT HAD NOT BEEN CHANGED (FOR THE SECOND TIME). I ASKED THE CO-CAPT TO RESET THE ALT PRESELECT, THEN MENTIONED THAT HE HAD NOT CHANGED FREQS. I THEN ASKED HIM TO VERIFY THE ASSIGNED HDG AFTER SILER (I HEARD 180 DEGS, WHILE 170 DEGS IS PUBLISHED). HIS REPLY 'SPLIT THE DIFFERENCE. FLY 175 DEGS.' WHILE TRYING TO RESOLVE THIS CONFUSION, I FLEW PAST SILER AND DID NOT MAKE THE HDG CHANGE OR REDUCE SPD AS PUBLISHED. ATC ASKED OUR SPD, OUR REPLY 240 KTS. ATC THEN SAID '210 DEGS IS PUBLISHED AND YOU MISSED YOUR TURN, TURN R TO 210 DEGS, DSND AND MAINTAIN 3000 FT.' I IMMEDIATELY COMPLIED AND REDUCED SPD. THE REST OF THE FLT WAS UNEVENTFUL. CONTRIBUTING FACTORS: FLT DECK WORKLOAD IN THE APCH CTL AREA. POOR CRM. SERIES OF 3 COMMANDS AT ONCE FROM ATC. I WAS SO BUSY MONITORING THE CO-CAPT'S ACTIONS AND INACTIONS (TRYING TO PRECLUDE AN ALT BUST), THAT I DID NOT DO MY JOB, IE, FLY THE STAR.
