Narrative:

We were executing a drake 6 departure out of phx and had just been issued a clearance to FL240. At the time we were established on the pxr 336 degrees right. We had just been issued a clearance present position, direct hector and were executing a climbing left turn. Passing through 12400 ft we received a TA at our 10 O'clock position. We immediately received a RA to stop climb, followed by 'descend, descend.' my response time was less than 3 seconds. Our ascent topped out at 12900 ft and the TCASII display indicated that the target aircraft was 400 ft above us. During this time we were IMC, and our rate of climb was at least 2000 FPM. We were equipped with B-1 engines, and we had been on an 'expedite through...' clearance on using B-2's and light we may well have not stopped our climb by 12900 ft.' I asked the first officer to request ATC to follow the flight progress of the target aircraft. Following our arrival in burbank, the first officer contacted ZAB by phone. Please be advised that I do not hold ATC responsible for the 'event.' they were very helpful and professional. This was one of those 'catch-22' sits that could have ended tragically.

Title: FLC OF MLG STOPPED ASSIGN SID CLB IN RESPONSE TO TCASII RA. NMAC.

Narrative: WE WERE EXECUTING A DRAKE 6 DEP OUT OF PHX AND HAD JUST BEEN ISSUED A CLRNC TO FL240. AT THE TIME WE WERE ESTABLISHED ON THE PXR 336 DEGS R. WE HAD JUST BEEN ISSUED A CLRNC PRESENT POS, DIRECT HECTOR AND WERE EXECUTING A CLBING L TURN. PASSING THROUGH 12400 FT WE RECEIVED A TA AT OUR 10 O'CLOCK POS. WE IMMEDIATELY RECEIVED A RA TO STOP CLB, FOLLOWED BY 'DSND, DSND.' MY RESPONSE TIME WAS LESS THAN 3 SECONDS. OUR ASCENT TOPPED OUT AT 12900 FT AND THE TCASII DISPLAY INDICATED THAT THE TARGET ACFT WAS 400 FT ABOVE US. DURING THIS TIME WE WERE IMC, AND OUR RATE OF CLB WAS AT LEAST 2000 FPM. WE WERE EQUIPPED WITH B-1 ENGS, AND WE HAD BEEN ON AN 'EXPEDITE THROUGH...' CLRNC ON USING B-2'S AND LIGHT WE MAY WELL HAVE NOT STOPPED OUR CLB BY 12900 FT.' I ASKED THE FO TO REQUEST ATC TO FOLLOW THE FLT PROGRESS OF THE TARGET ACFT. FOLLOWING OUR ARR IN BURBANK, THE FO CONTACTED ZAB BY PHONE. PLEASE BE ADVISED THAT I DO NOT HOLD ATC RESPONSIBLE FOR THE 'EVENT.' THEY WERE VERY HELPFUL AND PROFESSIONAL. THIS WAS ONE OF THOSE 'CATCH-22' SITS THAT COULD HAVE ENDED TRAGICALLY.
