ACR X NON ADHERENCE TO ATC CLRNC.

Narrative

ACR X DEPARTING ST THOMAS; VI. LNDG SAN JUAN PUERTO RICO. WE WERE ISSUED AND RECEIVED AN IFR CLRNC WHICH INCLUDED THE 'BACARDI 1' DEP FROM RWY 28 AT ST THOMAS TO JOIN THE PALCO 5 DEP. THE BACARDI ONE DEP DEPICTS A 250 DEG HDG TO INTERCEPT THE SAN JUAN 113 DEG RADIAL INBOUND TO SAN JUAN. UPON CONTACTING ST THOMAS TWR FOR TKOF CLRNC; WE REQUESTED TO MAINTAIN THE RWY HDG OF 280 DEGS TO INTERCEPT THE SAN JUAN 113 DEG RADIAL; WHICH WAS GRANTED SHORTLY THEREAFTER BY THE TWR CTLR WHILE WE HELD SHORT OF THE RWY. SHORTLY AFTER TKOF WE WERE INSTRUCTED TO CONTACT SAN JUAN APCH ON 128.65. UPON CONTACTING SAN JUAN APCH WE RECEIVED A STERN ORDER TO EXECUTE AN IMMEDIATE L TURN TO HDG OF 250 DEGS 'NOW;' IN ADDITION TO BEING ISSUED A TFC SAFETY ALERT DUE TO NEARBY INBOUND TFC. WE WERE THEN INSTRUCTED BY THE SAME CTLR TO CONTACT THEM BY TELEPHONE UPON ARRIVING AT SAN JUAN. WE LATER CONTACTED APCH CTL VIA TELEPHONE AND WERE TOLD THAT ST THOMAS TWR NEVER AUTHORIZED US TO MAINTAIN RWY HDG 280 DEGS AFTER TKOF AND THAT WE SIMPLY IGNORED THE PREVIOUSLY ISSUED 'BACARDI ONE DEP' CLRNC; DESPITE THE FACT THAT BOTH THE CAPT AND I CLRLY HEARD AND UNDERSTOOD THE RWY HDG INSTRUCTION ISSUED BY ST THOMAS TWR PRIOR TO TKOF. I STRONGLY FEEL THAT ST THOMAS TWR FAILED TO PROPERLY COORD AND RELAY OUR RWY HDG REQUEST TO SAN JUAN APCH; THUS CREATING THE TFC CONFLICT BTWN OUR DEPARTING FLT AND THE INBOUND TFC FLOW. FINALLY; I ALSO FEEL THAT THE ST THOMAS TWR CTLR INTENTIONALLY 'MISLED' APCH CTL DURING THE POST INCIDENT FOLLOW-UP WHICH GAVE APCH CTL THE IMPRESSION THAT WE WERE NOT GIVEN AUTHORIZATION TO MAINTAIN RWY HDG AFTER DEP.
