Narrative:

I called agc tower 10 mi east inbound landing. Was given: straight in runway 28, report 4 mi. Reported 4 mi out passing OM. At approximately 2 mi from airport an small aircraft B turned onto final in front of me (approximately 500 ft in front of me). Tower controller immediately called small aircraft B and issued a left turn for runway 31 which he complied with and I took no evasive action. I had heard the tower talking to the small aircraft B prior to this but paid no attention. Also I had heard the tower calling an aircraft using a call sign sometimes small aircraft C, sometimes small aircraft a, XXXX. He may have been trying to contact me but only 1 of 3 characters in the call sign were correct, and type of aircraft was 50/50. So I didn't ask if he wanted me. After landing on runway 28, tower called me using the incorrect call sign mentioned above with instruction to 'continue to next intersection, turn left, contact ground control.'
