Narrative:

TCASII alert went off in cockpit and we climbed to miss traffic at about 9000 ft. After traffic was sighted, we continued to 9000 ft. Phase of flight was approach to tpa international airport. Conflicting traffic sighted our airplane and made a call to tpa approach about us. He was in an small transport. He was at his assigned altitude and we were at ours.
