Narrative:

Flight air carrier X was 15 mi north of seymour johnson AFB at 6000 ft on a 265 degree heading direct sdz. Kc-10 (Y) departs seymour- johnson and cleared to 5000 ft on a northerly heading. Air carrier X calls traffic in sight. No 'maintain visual separation' given by seymour johnson. Kc-10 responds searching for traffic. Seymour johnson gives kc-10 climb clearance to 10000 ft. Kc-10 begins climb through air carrier X's altitude on a converging course. Captain (PNF) requests right turn from seymour johnson and tells first officer (PF) to turn right (north). TCASII RA commands 'descend' and first officer (PF) descends. Visually this action appeared correct. Seymour johnson then advises kc-10 to maintain 5000 ft. Kc-10 was already well above 5000 ft. At this point both aircraft are descending on a converging course. Kc-10 is approaching from left side and captain has visual and takes aircraft and begins maximum rate climb. TCASII reverses to 'climb, crossing, climb.' closest point of approach appeared to be 1/2 mi or less.

Title: LTT HAS CONFLICT WITH KC-10 ON ITS CLBOUT.

Narrative: FLT ACR X WAS 15 MI N OF SEYMOUR JOHNSON AFB AT 6000 FT ON A 265 DEG HDG DIRECT SDZ. KC-10 (Y) DEPARTS SEYMOUR- JOHNSON AND CLRED TO 5000 FT ON A NORTHERLY HDG. ACR X CALLS TFC IN SIGHT. NO 'MAINTAIN VISUAL SEPARATION' GIVEN BY SEYMOUR JOHNSON. KC-10 RESPONDS SEARCHING FOR TFC. SEYMOUR JOHNSON GIVES KC-10 CLB CLRNC TO 10000 FT. KC-10 BEGINS CLB THROUGH ACR X'S ALT ON A CONVERGING COURSE. CAPT (PNF) REQUESTS R TURN FROM SEYMOUR JOHNSON AND TELLS FO (PF) TO TURN R (N). TCASII RA COMMANDS 'DSND' AND FO (PF) DSNDS. VISUALLY THIS ACTION APPEARED CORRECT. SEYMOUR JOHNSON THEN ADVISES KC-10 TO MAINTAIN 5000 FT. KC-10 WAS ALREADY WELL ABOVE 5000 FT. AT THIS POINT BOTH ACFT ARE DSNDING ON A CONVERGING COURSE. KC-10 IS APCHING FROM L SIDE AND CAPT HAS VISUAL AND TAKES ACFT AND BEGINS MAX RATE CLB. TCASII REVERSES TO 'CLB, XING, CLB.' CLOSEST POINT OF APCH APPEARED TO BE 1/2 MI OR LESS.
