Narrative:

I (F0) was flying radar vectors on departure from lga. During initial climb, ny departure (120.4) cleared us 'direct white intersection, climb and maintain 15000 ft.' captain read back clearance to 15000 ft, set it in the dfgc and pointed. I verbally acknowledged '15000 ft, set and armed.' controller handed us off to ny departure control on 124.75. The captain checked in with the altitude we were passing -- approximately 7500 ft for 15000 ft. The controller acknowledged our check-in. As we climbed past 12600 ft, in the vicinity of the colts neck VOR, the controller asked us to verify leveling at 12000 ft. The captain replied that we were climbing to 15000 ft as cleared. The controller immediately told us to stop climb and descend to 12000 ft. As we leveled off, the controller apologized and said he had missed the altitude on our initial check-in. As we left his frequency, the controller again apologized and said the previous controller should not have cleared us above 12000 ft. He also stated that it was not a problem, since we were able to return to 12000 ft and no conflict had occurred.

Title: MD80 CREW OFF LGA WERE GIVEN AN INCORRECT CLB CLRNC TO 15000 FT, BUT AFTER HDOF TO SECOND CTLR, THE ALT WAS AMENDED TO 12000 FT.

Narrative: I (F0) WAS FLYING RADAR VECTORS ON DEP FROM LGA. DURING INITIAL CLB, NY DEP (120.4) CLRED US 'DIRECT WHITE INTXN, CLB AND MAINTAIN 15000 FT.' CAPT READ BACK CLRNC TO 15000 FT, SET IT IN THE DFGC AND POINTED. I VERBALLY ACKNOWLEDGED '15000 FT, SET AND ARMED.' CTLR HANDED US OFF TO NY DEP CTL ON 124.75. THE CAPT CHKED IN WITH THE ALT WE WERE PASSING -- APPROX 7500 FT FOR 15000 FT. THE CTLR ACKNOWLEDGED OUR CHK-IN. AS WE CLBED PAST 12600 FT, IN THE VICINITY OF THE COLTS NECK VOR, THE CTLR ASKED US TO VERIFY LEVELING AT 12000 FT. THE CAPT REPLIED THAT WE WERE CLBING TO 15000 FT AS CLRED. THE CTLR IMMEDIATELY TOLD US TO STOP CLB AND DSND TO 12000 FT. AS WE LEVELED OFF, THE CTLR APOLOGIZED AND SAID HE HAD MISSED THE ALT ON OUR INITIAL CHK-IN. AS WE LEFT HIS FREQ, THE CTLR AGAIN APOLOGIZED AND SAID THE PREVIOUS CTLR SHOULD NOT HAVE CLRED US ABOVE 12000 FT. HE ALSO STATED THAT IT WAS NOT A PROB, SINCE WE WERE ABLE TO RETURN TO 12000 FT AND NO CONFLICT HAD OCCURRED.
