Narrative:

Cpr X, C650, on 050 degree heading for hpn told to go RNAV direct brezy intersection then on course. Cpr Y, AC69, 5 NM intrail to cpr X on 050 degree heading also. (Brezy was about a 060 degree heading from cpr X position.) I looked away. When I looked back the 2 aircraft had just passed. I asked the cpr X his heading. It was 170 degrees (wrong direction for brezy). I turned him left and descended cpr Y to 2000 ft. I called traffic for the cpr Y, then cleared him for approach to teb. The 2 aircraft passed each other again (separated this time). Supplemental information from acn 266805: while being vectored after departure, ATC cleared us direct brezy. Utilizing the FMS, went toward the indicated point. ATC then questioned our heading and adjusted (160 degrees) it to send us toward brezy. During this time, we had multiple TCASII alerts, copilot was doing checklists and obtaining ATIS during this short flight (30 NM). Better positional awareness on my part could have prevented this, as could a quick xchk by PNF. FMS was subsequently found to be totally 'out to lunch' and written up by air crew for maintenance action.

Original NASA ASRS Text

Title: CPR X NON ADHERENCE TO ATC CLRNC HAD LTSS FROM CPR Y.

Narrative: CPR X, C650, ON 050 DEG HDG FOR HPN TOLD TO GO RNAV DIRECT BREZY INTXN THEN ON COURSE. CPR Y, AC69, 5 NM INTRAIL TO CPR X ON 050 DEG HDG ALSO. (BREZY WAS ABOUT A 060 DEG HDG FROM CPR X POS.) I LOOKED AWAY. WHEN I LOOKED BACK THE 2 ACFT HAD JUST PASSED. I ASKED THE CPR X HIS HDG. IT WAS 170 DEGS (WRONG DIRECTION FOR BREZY). I TURNED HIM L AND DSNDED CPR Y TO 2000 FT. I CALLED TFC FOR THE CPR Y, THEN CLRED HIM FOR APCH TO TEB. THE 2 ACFT PASSED EACH OTHER AGAIN (SEPARATED THIS TIME). SUPPLEMENTAL INFO FROM ACN 266805: WHILE BEING VECTORED AFTER DEP, ATC CLRED US DIRECT BREZY. UTILIZING THE FMS, WENT TOWARD THE INDICATED POINT. ATC THEN QUESTIONED OUR HDG AND ADJUSTED (160 DEGS) IT TO SEND US TOWARD BREZY. DURING THIS TIME, WE HAD MULTIPLE TCASII ALERTS, COPLT WAS DOING CHKLISTS AND OBTAINING ATIS DURING THIS SHORT FLT (30 NM). BETTER POSITIONAL AWARENESS ON MY PART COULD HAVE PREVENTED THIS, AS COULD A QUICK XCHK BY PNF. FMS WAS SUBSEQUENTLY FOUND TO BE TOTALLY 'OUT TO LUNCH' AND WRITTEN UP BY AIR CREW FOR MAINT ACTION.
