Narrative:
On climb out out of msy while deviating around thunderstorms, we were initially cleared to FL230. The clearance was changed to FL180, then FL190. The controller asked us to fly a 050 degrees for takeoff and WX which we did for a short time. Because of WX on that heading, we needed and asked for a 030 degree heading established on that heading, we heard another flight on the frequency. The controller called that traffic out to us at 10-11 O'clock position at FL190. We repeated we were level at FL190. The controller came back with immediate instructions to fly heading 070 degrees and descend to FL180. We complied with those instructions. We never saw the traffic, either visually or on TCASII. We did not take evasive action only followed the controller's instructions.
Original NASA ASRS Text
Title: A DC9-50 FLC WAS GIVEN AN IMMEDIATE DSCNT AND HEADING TO AVOID CONFLICTING TFC NEAR MSY. SEPARATION WAS NEVER LOST.
Narrative: ON CLBOUT OUT OF MSY WHILE DEVIATING AROUND TSTMS, WE WERE INITIALLY CLRED TO FL230. THE CLRNC WAS CHANGED TO FL180, THEN FL190. THE CTLR ASKED US TO FLY A 050 DEGS FOR TKOF AND WX WHICH WE DID FOR A SHORT TIME. BECAUSE OF WX ON THAT HEADING, WE NEEDED AND ASKED FOR A 030 DEG HDG ESTABLISHED ON THAT HEADING, WE HEARD ANOTHER FLT ON THE FREQ. THE CTLR CALLED THAT TFC OUT TO US AT 10-11 O'CLOCK POS AT FL190. WE REPEATED WE WERE LEVEL AT FL190. THE CTLR CAME BACK WITH IMMEDIATE INSTRUCTIONS TO FLY HDG 070 DEGS AND DSND TO FL180. WE COMPLIED WITH THOSE INSTRUCTIONS. WE NEVER SAW THE TFC, EITHER VISUALLY OR ON TCASII. WE DID NOT TAKE EVASIVE ACTION ONLY FOLLOWED THE CTLR'S INSTRUCTIONS.
