Narrative:

At cruise 11000 ft approximately 3 NM southwest of orw VOR, ZBW reported traffic, a BE1900D, 12 O'clock, 7 mi, swbound. TCASII gave TA. Traffic acquired visually. TCASII then went to RA mode. Traffic level at 10500 ft. No evasive action taken. Center then advised of a second target 5 mi in trail of the BE1900. At 10000 ft second TCASII TA, TCASII went to RA mode with climb command. TCASII showed second target climbing through 10500 ft. PF did not respond to initial climb command with second climb command. I disengaged the autoplt and initiated a climb. The PF then resumed control of the aircraft. When the TCASII initiated the RA ZBW gave us a frequency change to pvd approach. We advised ZBW we were responding to an RA and switched to pvd approach. We checked in with pvd descending to our assigned altitude of 11000 ft (out of 11500 ft) after responding to an RA. Remainder of flight without incident. I feel the main factors were the 2 targets in close proximity to one another. The frequency change and the failure of the PF to initially respond to the TCASII RA. After we had returned to our assigned altitude the PF stated that I had now caused him to have to fill out paperwork about the response to the RA. I feel his delay was an effort to visually acquire the target to avoid the evasive maneuver, and in the end avoid the paperwork. I feel to correct the problem all pilots must respond to a TCASII RA as with any other problem/emergency and not consider the possible paperwork that may be required.

Title: AN ACR FLC RECEIVE 2 DIFFERENT TCASII RA'S IN RAPID SUCCESSION. THE FIRST THEY ACQUIRE VISUALLY AND THE SECOND THEY CLB TO EVADE.

Narrative: AT CRUISE 11000 FT APPROX 3 NM SW OF ORW VOR, ZBW RPTED TFC, A BE1900D, 12 O'CLOCK, 7 MI, SWBOUND. TCASII GAVE TA. TFC ACQUIRED VISUALLY. TCASII THEN WENT TO RA MODE. TFC LEVEL AT 10500 FT. NO EVASIVE ACTION TAKEN. CTR THEN ADVISED OF A SECOND TARGET 5 MI IN TRAIL OF THE BE1900. AT 10000 FT SECOND TCASII TA, TCASII WENT TO RA MODE WITH CLB COMMAND. TCASII SHOWED SECOND TARGET CLBING THROUGH 10500 FT. PF DID NOT RESPOND TO INITIAL CLB COMMAND WITH SECOND CLB COMMAND. I DISENGAGED THE AUTOPLT AND INITIATED A CLB. THE PF THEN RESUMED CTL OF THE ACFT. WHEN THE TCASII INITIATED THE RA ZBW GAVE US A FREQ CHANGE TO PVD APCH. WE ADVISED ZBW WE WERE RESPONDING TO AN RA AND SWITCHED TO PVD APCH. WE CHKED IN WITH PVD DSNDING TO OUR ASSIGNED ALT OF 11000 FT (OUT OF 11500 FT) AFTER RESPONDING TO AN RA. REMAINDER OF FLT WITHOUT INCIDENT. I FEEL THE MAIN FACTORS WERE THE 2 TARGETS IN CLOSE PROX TO ONE ANOTHER. THE FREQ CHANGE AND THE FAILURE OF THE PF TO INITIALLY RESPOND TO THE TCASII RA. AFTER WE HAD RETURNED TO OUR ASSIGNED ALT THE PF STATED THAT I HAD NOW CAUSED HIM TO HAVE TO FILL OUT PAPERWORK ABOUT THE RESPONSE TO THE RA. I FEEL HIS DELAY WAS AN EFFORT TO VISUALLY ACQUIRE THE TARGET TO AVOID THE EVASIVE MANEUVER, AND IN THE END AVOID THE PAPERWORK. I FEEL TO CORRECT THE PROB ALL PLTS MUST RESPOND TO A TCASII RA AS WITH ANY OTHER PROB/EMER AND NOT CONSIDER THE POSSIBLE PAPERWORK THAT MAY BE REQUIRED.
