Narrative:

I was flying direct to gle using my garmin 430. I was monitoring the radio but not using it for position reporting. I flew into gle; left downwind for runway 35 at a 45 degree angle; southwest. I heard the king air state that he was on final before I was on downwind. Prior to me turning base for runway 35; the king air stated again; that he was on final. The king air did not fly a pattern approach to land and must have flown a 'direct to final' (long final). I waited for the king air to pass my left wing before turning to left base for runway 35. Before my wheels touched down; the king air had cleared the active runway. Once on the ground; the pilot of the king air stated that we almost had a midair collision. He had TCAS on board and evidently it gave a warning light. He also stated that he called back to center for position of my aircraft. The king air pilot stated that we had only 100 ft of separation. I first spotted the king air while I was on left downwind for runway 35. We must have came close to colliding much further south of the airport; if in fact we did. I will use my radio; always; from this point forward even though it may not be a requirement at gle (uncontrolled airspace and no tower). I do believe that the king air; since he had visual contact and TCAS on board; should not have allowed us to get as close as 100 ft of separation.

Title: C-205 IS INVOLVED IN NMAC WHILE LNDG AT UNCONTROLLED ARPT.

Narrative: I WAS FLYING DIRECT TO GLE USING MY GARMIN 430. I WAS MONITORING THE RADIO BUT NOT USING IT FOR POS REPORTING. I FLEW INTO GLE; L DOWNWIND FOR RWY 35 AT A 45 DEG ANGLE; SW. I HEARD THE KING AIR STATE THAT HE WAS ON FINAL BEFORE I WAS ON DOWNWIND. PRIOR TO ME TURNING BASE FOR RWY 35; THE KING AIR STATED AGAIN; THAT HE WAS ON FINAL. THE KING AIR DID NOT FLY A PATTERN APCH TO LAND AND MUST HAVE FLOWN A 'DIRECT TO FINAL' (LONG FINAL). I WAITED FOR THE KING AIR TO PASS MY L WING BEFORE TURNING TO L BASE FOR RWY 35. BEFORE MY WHEELS TOUCHED DOWN; THE KING AIR HAD CLRED THE ACTIVE RWY. ONCE ON THE GND; THE PLT OF THE KING AIR STATED THAT WE ALMOST HAD A MIDAIR COLLISION. HE HAD TCAS ON BOARD AND EVIDENTLY IT GAVE A WARNING LIGHT. HE ALSO STATED THAT HE CALLED BACK TO CTR FOR POS OF MY ACFT. THE KING AIR PLT STATED THAT WE HAD ONLY 100 FT OF SEPARATION. I FIRST SPOTTED THE KING AIR WHILE I WAS ON L DOWNWIND FOR RWY 35. WE MUST HAVE CAME CLOSE TO COLLIDING MUCH FURTHER S OF THE ARPT; IF IN FACT WE DID. I WILL USE MY RADIO; ALWAYS; FROM THIS POINT FORWARD EVEN THOUGH IT MAY NOT BE A REQUIREMENT AT GLE (UNCTLED AIRSPACE AND NO TWR). I DO BELIEVE THAT THE KING AIR; SINCE HE HAD VISUAL CONTACT AND TCAS ON BOARD; SHOULD NOT HAVE ALLOWED US TO GET AS CLOSE AS 100 FT OF SEPARATION.
