Narrative:

During nanci arrival into lga, aircraft was vectored 090 degree heading to intercept 045 degrees into lga for expressway visual, cleared to 6000 ft. At approximately 6800 ft, descending to 6000 ft, received TCASII 'traffic, traffic.' traffic visually acquired behind moving left to right level 6000 ft. Crew queried controller who stated that he meant to clear us to 7000 ft MSL, but traffic was behind and not a problem and to continue with expressway visual. Flight progressed uneventfully.

Title: APCH CTLR CLRED FLC TO 6000 FT AND AT 6800 FT FLC OBSERVED CONFLICTING TFC AT 6000 FT. WHEN FLC QUESTIONED CTLR, HE SAID HE MEANT TO CLR THEM TO 7000 FT.

Narrative: DURING NANCI ARR INTO LGA, ACFT WAS VECTORED 090 DEG HDG TO INTERCEPT 045 DEGS INTO LGA FOR EXPRESSWAY VISUAL, CLRED TO 6000 FT. AT APPROX 6800 FT, DSNDING TO 6000 FT, RECEIVED TCASII 'TFC, TFC.' TFC VISUALLY ACQUIRED BEHIND MOVING L TO R LEVEL 6000 FT. CREW QUERIED CTLR WHO STATED THAT HE MEANT TO CLR US TO 7000 FT MSL, BUT TFC WAS BEHIND AND NOT A PROB AND TO CONTINUE WITH EXPRESSWAY VISUAL. FLT PROGRESSED UNEVENTFULLY.
