Narrative:

We were deviating for thunderstorms on departure. We were asked to climb as rapidly as possible through 13000 ft with a clearance to 17000 ft. Going through 13300 ft, the controller told us to descend immediately to 13000 ft. At the same time we had a traffic call on the TCASII. It appeared that the traffic passed about 3 mi off our left, at which time we had descended to 13000 ft, the traffic being at 14000 ft. I think the conflict arose because we were unable to correct right to return to the airway as quickly as we first thought. Due to frequency congestion (the primary contributing factor) we were unable to convey this to the controller. A contributing factor may have been that the departure controller was handling us above the normal 12000 ft ceiling for departure.

Original NASA ASRS Text

Title: ACR FLC ON 'EXPEDITE' CLRNC RECEIVED TCASII TA WHILE DEVIATING FOR WX.

Narrative: WE WERE DEVIATING FOR TSTMS ON DEP. WE WERE ASKED TO CLB AS RAPIDLY AS POSSIBLE THROUGH 13000 FT WITH A CLRNC TO 17000 FT. GOING THROUGH 13300 FT, THE CTLR TOLD US TO DSND IMMEDIATELY TO 13000 FT. AT THE SAME TIME WE HAD A TFC CALL ON THE TCASII. IT APPEARED THAT THE TFC PASSED ABOUT 3 MI OFF OUR L, AT WHICH TIME WE HAD DSNDED TO 13000 FT, THE TFC BEING AT 14000 FT. I THINK THE CONFLICT AROSE BECAUSE WE WERE UNABLE TO CORRECT R TO RETURN TO THE AIRWAY AS QUICKLY AS WE FIRST THOUGHT. DUE TO FREQ CONGESTION (THE PRIMARY CONTRIBUTING FACTOR) WE WERE UNABLE TO CONVEY THIS TO THE CTLR. A CONTRIBUTING FACTOR MAY HAVE BEEN THAT THE DEP CTLR WAS HANDLING US ABOVE THE NORMAL 12000 FT CEILING FOR DEP.
