Narrative:

I was cleared to take off runway 35; with ATIS information; for a 4-HAND turnout to the sse. As I taxied into position; I heard the ardmore tower clear another aircraft to land; but do not recall at this time if a runway was associated with that overheard clearance. Still while aligning my aircraft with runway 35 centerline; I scanned departure end and out to the horizon for a previous aircraft taking off ahead of me. (He was a pilot and aircraft known by me; and was already well clear of my departure path; to the east.) at this time; I noticed a second aircraft; wbound; close in to the departure end of runway 35 (e.g.; on base leg for runway 17). I commenced my takeoff roll and became airborne quickly; still watching traffic on base to runway 17. When that aircraft turned towards the runway (eg; turned final runway 17); I was at about 1/2 way down runway 35. At about 200 ft AGL; as soon as I ascertained that aircraft was landing opposite me; I simultaneously took extreme evasive action by banking severely to the right; and descending slightly. Also; I asked the tower if he knew he had traffic very short final on runway 17. Tower responded with something like 'aircraft on final to runway 17; turn immediate left.' I then responded to tower with 'turn him right; turn him right.' the aircraft continued to turn left. We did not hit -- barely! My opinion on this incident: 3 things happened that should not have -- 1) the pilot was telling the tower incorrect information on the aircraft's location; meaning the pilot was very confused as to: a) what direction he was flying; B) what runway he was cleared for; and 3) maybe; where he was; airport-wise. 2) the tower didn't know where the aircraft was; yet cleared him to land; while I was just taking the active. 3)after the threat was being addressed; while I initiated r-hand avoidance maneuvers; the tower instructed the aircraft to turn left; which he did dutifully -- right into my immediate flight path! Had I not aggressively maneuvered and descended; I most likely would not be writing this.

Title: TWO SMALL AIRCRAFT HAD A NMAC AS ONE AIRCRAFT DEPARTED ADM WHILE ANOTHER WAS ON FINAL IN OPPOSITE DIRECTION.

Narrative: I WAS CLRED TO TAKE OFF RWY 35; WITH ATIS INFO; FOR A 4-HAND TURNOUT TO THE SSE. AS I TAXIED INTO POSITION; I HEARD THE ARDMORE TWR CLR ANOTHER ACFT TO LAND; BUT DO NOT RECALL AT THIS TIME IF A RWY WAS ASSOCIATED WITH THAT OVERHEARD CLRNC. STILL WHILE ALIGNING MY ACFT WITH RWY 35 CTRLINE; I SCANNED DEP END AND OUT TO THE HORIZON FOR A PREVIOUS ACFT TAKING OFF AHEAD OF ME. (HE WAS A PLT AND ACFT KNOWN BY ME; AND WAS ALREADY WELL CLEAR OF MY DEP PATH; TO THE E.) AT THIS TIME; I NOTICED A SECOND ACFT; WBOUND; CLOSE IN TO THE DEP END OF RWY 35 (E.G.; ON BASE LEG FOR RWY 17). I COMMENCED MY TKOF ROLL AND BECAME AIRBORNE QUICKLY; STILL WATCHING TFC ON BASE TO RWY 17. WHEN THAT ACFT TURNED TOWARDS THE RWY (EG; TURNED FINAL RWY 17); I WAS AT ABOUT 1/2 WAY DOWN RWY 35. AT ABOUT 200 FT AGL; AS SOON AS I ASCERTAINED THAT ACFT WAS LNDG OPPOSITE ME; I SIMULTANEOUSLY TOOK EXTREME EVASIVE ACTION BY BANKING SEVERELY TO THE R; AND DSNDING SLIGHTLY. ALSO; I ASKED THE TWR IF HE KNEW HE HAD TFC VERY SHORT FINAL ON RWY 17. TWR RESPONDED WITH SOMETHING LIKE 'ACFT ON FINAL TO RWY 17; TURN IMMEDIATE L.' I THEN RESPONDED TO TWR WITH 'TURN HIM R; TURN HIM R.' THE ACFT CONTINUED TO TURN L. WE DID NOT HIT -- BARELY! MY OPINION ON THIS INCIDENT: 3 THINGS HAPPENED THAT SHOULD NOT HAVE -- 1) THE PLT WAS TELLING THE TWR INCORRECT INFO ON THE ACFT'S LOCATION; MEANING THE PLT WAS VERY CONFUSED AS TO: A) WHAT DIRECTION HE WAS FLYING; B) WHAT RWY HE WAS CLRED FOR; AND 3) MAYBE; WHERE HE WAS; ARPT-WISE. 2) THE TWR DIDN'T KNOW WHERE THE ACFT WAS; YET CLRED HIM TO LAND; WHILE I WAS JUST TAKING THE ACTIVE. 3)AFTER THE THREAT WAS BEING ADDRESSED; WHILE I INITIATED R-HAND AVOIDANCE MANEUVERS; THE TWR INSTRUCTED THE ACFT TO TURN L; WHICH HE DID DUTIFULLY -- RIGHT INTO MY IMMEDIATE FLT PATH! HAD I NOT AGGRESSIVELY MANEUVERED AND DSNDED; I MOST LIKELY WOULD NOT BE WRITING THIS.
