Narrative:
Medium large transport was #1, cleared to land runway 34. MTR was #2 with medium large transport in sight. MTR was approaching high and behind medium large transport for an overhead break for runway 34. Medium large transport received a TCASII advisory 'limit vertical speed' and reduced rate of descent. Medium large transport then elected to go around because they were too high to land. After medium large transport initiated go around and advised tower, the tower controller instructed medium large transport 'do not climb.' this instruction was necessary due to the MTR's elevation and high rate of closure (approximately 1/4 mi behind and 200 ft above medium large transport). MTR was then instructed to turn right to the downwind, thus avoiding any conflict with the medium large transport. The medium large transport then resumed a normal go around, circled back to the airport VFR and landed. The pilot of the medium large transport reported that clutter on the TCASII screen prevented him from seeing the altitude on the MTR.

Title: MLG TCASII RA EXECUTED GAR ON FINAL APCH HAD CONFLICT WITH MTR ENTERING TFC PATTERN. SEE AND AVOID CONCEPT.
Narrative: MLG WAS #1, CLRED TO LAND RWY 34. MTR WAS #2 WITH MLG IN SIGHT. MTR WAS APCHING HIGH AND BEHIND MLG FOR AN OVERHEAD BREAK FOR RWY 34. MLG RECEIVED A TCASII ADVISORY 'LIMIT VERT SPD' AND REDUCED RATE OF DSCNT. MLG THEN ELECTED TO GAR BECAUSE THEY WERE TOO HIGH TO LAND. AFTER MLG INITIATED GAR AND ADVISED TWR, THE TWR CTLR INSTRUCTED MLG 'DO NOT CLB.' THIS INSTRUCTION WAS NECESSARY DUE TO THE MTR'S ELEVATION AND HIGH RATE OF CLOSURE (APPROX 1/4 MI BEHIND AND 200 FT ABOVE MLG). MTR WAS THEN INSTRUCTED TO TURN R TO THE DOWNWIND, THUS AVOIDING ANY CONFLICT WITH THE MLG. THE MLG THEN RESUMED A NORMAL GAR, CIRCLED BACK TO THE ARPT VFR AND LANDED. THE PLT OF THE MLG RPTED THAT CLUTTER ON THE TCASII SCREEN PREVENTED HIM FROM SEEING THE ALT ON THE MTR.
