Narrative:

Approach control: 'maintain 3500' until 3 mi final. Cleared for visibility runway 1L. If you stay inside 3 mi, you can turn in now. Cleared for visibility runway 1L.' medium large transport: 'roger, we'll stay inside 3 mi. Cleared for visibility runway 1L.' approach control: 'contact tower 118.2.' medium large transport: '118.2, roger.' ict tower: 'medium large transport, are you on frequency?' medium large transport: 'roger, medium large transport on 118.2.' ict tower: 'medium large transport cleared to land. Approach control had you restr to 3500'.' at this point a normal landing was made. When we did see conflicting aircraft, the approximately sep was 300' vertical and 1/4-1/2 mi horizontal. The PF increased bank and lowered nose in response. Pilot called approach control via phone to discuss situation with controller. It was the controller's opinion that it was miscom on both parts and that they had no intentions of initiating enforcement actions.

Title: ACFT CLEARED FOR A VISUAL APCH DESCENDED BELOW AN ALT RESTRICTION AND CAME CLOSE TO ANOTHER ACFT.

Narrative: APCH CTL: 'MAINTAIN 3500' UNTIL 3 MI FINAL. CLRED FOR VIS RWY 1L. IF YOU STAY INSIDE 3 MI, YOU CAN TURN IN NOW. CLRED FOR VIS RWY 1L.' MLG: 'ROGER, WE'LL STAY INSIDE 3 MI. CLRED FOR VIS RWY 1L.' APCH CTL: 'CONTACT TWR 118.2.' MLG: '118.2, ROGER.' ICT TWR: 'MLG, ARE YOU ON FREQ?' MLG: 'ROGER, MLG ON 118.2.' ICT TWR: 'MLG CLRED TO LAND. APCH CTL HAD YOU RESTR TO 3500'.' AT THIS POINT A NORMAL LNDG WAS MADE. WHEN WE DID SEE CONFLICTING ACFT, THE APPROX SEP WAS 300' VERT AND 1/4-1/2 MI HORIZ. THE PF INCREASED BANK AND LOWERED NOSE IN RESPONSE. PLT CALLED APCH CTL VIA PHONE TO DISCUSS SITUATION WITH CTLR. IT WAS THE CTLR'S OPINION THAT IT WAS MISCOM ON BOTH PARTS AND THAT THEY HAD NO INTENTIONS OF INITIATING ENFORCEMENT ACTIONS.
