Narrative:

Air carrier X was sebound on col 350 degree radial. Air carrier Y was wbound direct to rbv VOR. I informed air carrier X and air carrier Y of each other. Both aircraft had the other in sight. I advised air carrier X that air carrier Y would pass behind him. Air carrier Y appeared to adjust his heading for rbv. Both aircraft had TCASII. As air carrier Y got closer to air carrier X, air carrier X stated to have an RA to descent. Air carrier Y stated he had the same signal. Both were climbing out of 13000 ft for 17000 ft. Later, air carrier X stated he had an RA to descend, followed by an RA to climb. Air carrier Y stated he had an RA to climb followed by an RA to descend. Neither aircraft appeared to follow their RA's. I could have saved myself a lot of trouble by telling air carrier Y to maintain visual with air carrier X, but I believe that TCASII contributed to the operational error. TCASII stage ii is causing a lot of problems in the new york area. I can't wait to see tcasiii, that should be fun!

Original NASA ASRS Text

Title: CTLR HAD LTSS WITH 2 ACR'S IN CLB. BLAMES TCASII.

Narrative: ACR X WAS SEBOUND ON COL 350 DEG RADIAL. ACR Y WAS WBOUND DIRECT TO RBV VOR. I INFORMED ACR X AND ACR Y OF EACH OTHER. BOTH ACFT HAD THE OTHER IN SIGHT. I ADVISED ACR X THAT ACR Y WOULD PASS BEHIND HIM. ACR Y APPEARED TO ADJUST HIS HDG FOR RBV. BOTH ACFT HAD TCASII. AS ACR Y GOT CLOSER TO ACR X, ACR X STATED TO HAVE AN RA TO DSCNT. ACR Y STATED HE HAD THE SAME SIGNAL. BOTH WERE CLBING OUT OF 13000 FT FOR 17000 FT. LATER, ACR X STATED HE HAD AN RA TO DSND, FOLLOWED BY AN RA TO CLB. ACR Y STATED HE HAD AN RA TO CLB FOLLOWED BY AN RA TO DSND. NEITHER ACFT APPEARED TO FOLLOW THEIR RA'S. I COULD HAVE SAVED MYSELF A LOT OF TROUBLE BY TELLING ACR Y TO MAINTAIN VISUAL WITH ACR X, BUT I BELIEVE THAT TCASII CONTRIBUTED TO THE OPERROR. TCASII STAGE II IS CAUSING A LOT OF PROBS IN THE NEW YORK AREA. I CAN'T WAIT TO SEE TCASIII, THAT SHOULD BE FUN!
