Narrative:
Departed cold springs airport on runway 17 -- made left turn to heading 010 degrees, climbed to 11000 ft. TCASII gave us a warning -- also shortly thereafter, a RA to 'climb' along with associated red and green lights on ivsi. We complied with RA and climbed to 11800 ft to avoid conflict. We never saw aircraft and notified controller of near miss. He confirmed that there was a twin engine aircraft at 10500 ft. TCASII showed aircraft approximately 500 ft below us and climbing through our altitude of 11000 ft. Without TCASII issuing the RA, we could have hit that aircraft.

Title: ALTDEV ALT EXCURSION OCCURS AFTER PLT RESPONSE TO TCASII RA ON CLBING XING TFC.
Narrative: DEPARTED COLD SPRINGS ARPT ON RWY 17 -- MADE L TURN TO HDG 010 DEGS, CLBED TO 11000 FT. TCASII GAVE US A WARNING -- ALSO SHORTLY THEREAFTER, A RA TO 'CLB' ALONG WITH ASSOCIATED RED AND GREEN LIGHTS ON IVSI. WE COMPLIED WITH RA AND CLBED TO 11800 FT TO AVOID CONFLICT. WE NEVER SAW ACFT AND NOTIFIED CTLR OF NEAR MISS. HE CONFIRMED THAT THERE WAS A TWIN ENG ACFT AT 10500 FT. TCASII SHOWED ACFT APPROX 500 FT BELOW US AND CLBING THROUGH OUR ALT OF 11000 FT. WITHOUT TCASII ISSUING THE RA, WE COULD HAVE HIT THAT ACFT.
