Narrative:

After departure from teb on the teb 5 departure, we were handed over to ny TRACON. Controller issued a turn to 80 degrees. I acknowledged the turn and turned left to 80 degrees. Approximately 1 min later controller issued an immediate right turn to 310 degrees. We then received a yellow traffic alert. Followed by a red 'resolution' advisory indicating a descent. We descended to 1000 ft MSL. We were then given an immediate climb to 5000 ft and then another climb to 6000 ft. The controller then proceeded to question our first turn to 80 degrees. We advised him that we acknowledged his instructions and followed them. He then stated he did not give that instruction, he would never turn us away from our next fix. Both pilots in our aircraft confirmed his first instruction and turned accordingly. His miscommunication with us caused confusion and TCAS warnings and resolutions. Callback conversation with reporter revealed the following information: the non flying first officer said he was sure the traffic initiating the TCAS was a VFR small aircraft in the teb class D who was either landing or departing teb. The reporter said the 80 degree heading was clearly enunciated by the N90 controller, read back to the controller, and acknowledged by the controller. The WX was reported as no ceiling and more than 10 miles visibility. The first officer was unsure of the exact type of TCAS in his aircraft, but said it was fully functional and one of the latest models. The reporter indicated no follow up action was initiated by the flight crew and no subsequent contact made by ATC.

APPROX 1 MIN LATER CTLR ISSUED AN IMMEDIATE R TURN TO 310 DEGS. WE THEN RECEIVED A YELLOW TFC ALERT. FOLLOWED BY A RED 'RESOLUTION' ADVISORY INDICATING A DESCENT. WE DESCENDED TO 1000 FT MSL.

WE ADVISED HIM THAT WE ACKNOWLEDGED HIS INSTRUCTIONS AND FOLLOWED THEM. HE THEN STATED HE DID NOT GIVE THAT INSTRUCTION, HE WOULD NEVER TURN US AWAY FROM OUR NEXT FIX. BOTH PLTS IN OUR ACFT CONFIRMED HIS FIRST INSTRUCTION AND TURNED ACCORDINGLY. HIS MISCOMMUNICATION WITH US CAUSED CONFUSION AND TCAS WARNINGS AND RESOLUTIONS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE NON FLYING FO SAID HE WAS SURE THE TFC INITIATING THE TCAS WAS A VFR SMALL ACFT IN THE TEB CLASS D WHO WAS EITHER LNDG OR DEPARTING TEB. THE RPTR SAID THE 80 DEG HEADING WAS CLEARLY ENUNCIATED BY THE N90 CTLR, READ BACK TO THE CTLR, AND ACKNOWLEDGED BY THE CTLR. THE WX WAS RPTED AS NO CEILING AND MORE THAN 10 MILES VIS.
