Narrative:
Given descent to cross hli at 10000 ft. We were on a heading at the time, told to turn right 20 degrees for our descent. I turned right 20 degrees while going through FL210. I believe right 20 degrees was read back. At 19700 ft, we were told to turn immediately to left 180 degrees and level at FL190. We also had a TCASII TA. I manually turned the aircraft and leveled off at FL190. Controller said he had given us a left 20 degrees, not right. We had the other traffic on TCASII at a distance of 5 mi and 1000 ft below us. Talking in the cockpit we both thought our turn was to the right. I am not sure what can be done any differently. I guess just listen better and read back a heading, not just right 20 degrees.

Title: AN ACR FLC FLYING F100 NEAR HLI FAILED TO FOLLOW ATC INSTRUCTIONS FOR A HDG CHANGE RESULTING IN A TRACK DEV.
Narrative: GIVEN DSCNT TO CROSS HLI AT 10000 FT. WE WERE ON A HDG AT THE TIME, TOLD TO TURN R 20 DEGS FOR OUR DSCNT. I TURNED R 20 DEGS WHILE GOING THROUGH FL210. I BELIEVE R 20 DEGS WAS READ BACK. AT 19700 FT, WE WERE TOLD TO TURN IMMEDIATELY TO L 180 DEGS AND LEVEL AT FL190. WE ALSO HAD A TCASII TA. I MANUALLY TURNED THE ACFT AND LEVELED OFF AT FL190. CTLR SAID HE HAD GIVEN US A L 20 DEGS, NOT R. WE HAD THE OTHER TFC ON TCASII AT A DISTANCE OF 5 MI AND 1000 FT BELOW US. TALKING IN THE COCKPIT WE BOTH THOUGHT OUR TURN WAS TO THE R. I AM NOT SURE WHAT CAN BE DONE ANY DIFFERENTLY. I GUESS JUST LISTEN BETTER AND READ BACK A HDG, NOT JUST R 20 DEGS.
