Narrative:

The first officer was flying the last leg of a 3 day trip from lga to dfw. He was new on the aircraft. He had done a few things that I considered nonstandard per procedures and I had mentioned them to him. As he started his final approach at dfw, the controller said 'follow the traffic 3 1/2 mi ahead of you and maintain 180 KTS until the marker.' a short time later, he (first officer) said to me, 'I am going to slow, I think I am catching the guy ahead.' he proceeded to slow to a speed of 130 KTS, 3 mi outside the OM. About this time, we called tower and they asked us our speed. I told them 130 KTS, and they then gave us a clearance of 'turn left heading 030 degrees, maintain 3000 ft and call approach.' they had pulled us right out of the pattern for runway 17C. Upon contact with approach, he told us he pulled us out because we did not maintain our speed. Safety was not compromised, but we did err in not complying with a clearance. When we got on the ground I had a discussion with the first officer and explained that this was the problem that I had experienced with him during the trip. In several instances he just seemed to believe that he had a better way of doing things and I explained that we had to do them both the airline way and the ATC way. Supplemental information from acn 422230: I did not hear the speed assignment, but the captain told me later he did. We were a little close to our interval in front and I intentionally slowed early, having missed regional's speed assignment to us.

Title: MD80 CREW INSTRUCTED BY TRACON TO GAR AFTER FAILING TO COMPLY WITH SPD RESTR IN DFW AIRSPACE.

Narrative: THE FO WAS FLYING THE LAST LEG OF A 3 DAY TRIP FROM LGA TO DFW. HE WAS NEW ON THE ACFT. HE HAD DONE A FEW THINGS THAT I CONSIDERED NONSTANDARD PER PROCS AND I HAD MENTIONED THEM TO HIM. AS HE STARTED HIS FINAL APCH AT DFW, THE CTLR SAID 'FOLLOW THE TFC 3 1/2 MI AHEAD OF YOU AND MAINTAIN 180 KTS UNTIL THE MARKER.' A SHORT TIME LATER, HE (FO) SAID TO ME, 'I AM GOING TO SLOW, I THINK I AM CATCHING THE GUY AHEAD.' HE PROCEEDED TO SLOW TO A SPD OF 130 KTS, 3 MI OUTSIDE THE OM. ABOUT THIS TIME, WE CALLED TWR AND THEY ASKED US OUR SPD. I TOLD THEM 130 KTS, AND THEY THEN GAVE US A CLRNC OF 'TURN L HDG 030 DEGS, MAINTAIN 3000 FT AND CALL APCH.' THEY HAD PULLED US RIGHT OUT OF THE PATTERN FOR RWY 17C. UPON CONTACT WITH APCH, HE TOLD US HE PULLED US OUT BECAUSE WE DID NOT MAINTAIN OUR SPD. SAFETY WAS NOT COMPROMISED, BUT WE DID ERR IN NOT COMPLYING WITH A CLRNC. WHEN WE GOT ON THE GND I HAD A DISCUSSION WITH THE FO AND EXPLAINED THAT THIS WAS THE PROB THAT I HAD EXPERIENCED WITH HIM DURING THE TRIP. IN SEVERAL INSTANCES HE JUST SEEMED TO BELIEVE THAT HE HAD A BETTER WAY OF DOING THINGS AND I EXPLAINED THAT WE HAD TO DO THEM BOTH THE AIRLINE WAY AND THE ATC WAY. SUPPLEMENTAL INFO FROM ACN 422230: I DID NOT HEAR THE SPD ASSIGNMENT, BUT THE CAPT TOLD ME LATER HE DID. WE WERE A LITTLE CLOSE TO OUR INTERVAL IN FRONT AND I INTENTIONALLY SLOWED EARLY, HAVING MISSED REGIONAL'S SPD ASSIGNMENT TO US.
