Narrative:
On climb out from lga, destination mia, approaching 13000 ft in climb to 15000 ft, controller queried if we were leveling at 12000 ft. We reported that we were cleared to 15000 ft. Controller advised us that we were only cleared to 12000 ft, to descend to that altitude and to turn towards the west. We immediately complied. We had 15000 ft set in the altitude select window. When we checked in on this controller's frequency we reported that we were in the climb to 15000 ft. The error occurred on the previous controller's frequency, the first controller after departure from lga, however the subsequent controller did not catch the error when we checked in and reported climbing to 15000 ft. Neither my copilot (who was working the radios) nor myself (captain and PF) are certain whose error caused the altitude deviation. The departure phase is particularly busy, and this incident reinforces the critical need for all parties to hear and xchk altitude clrncs and readbacks.
Original NASA ASRS Text
Title: AN ACR LGT OVERSHOT ITS ALT IN CLB. RPTR CITES HEARBACK PROB WITH N90 CTLR.
Narrative: ON CLBOUT FROM LGA, DEST MIA, APCHING 13000 FT IN CLB TO 15000 FT, CTLR QUERIED IF WE WERE LEVELING AT 12000 FT. WE RPTED THAT WE WERE CLRED TO 15000 FT. CTLR ADVISED US THAT WE WERE ONLY CLRED TO 12000 FT, TO DSND TO THAT ALT AND TO TURN TOWARDS THE W. WE IMMEDIATELY COMPLIED. WE HAD 15000 FT SET IN THE ALT SELECT WINDOW. WHEN WE CHKED IN ON THIS CTLR'S FREQ WE RPTED THAT WE WERE IN THE CLB TO 15000 FT. THE ERROR OCCURRED ON THE PREVIOUS CTLR'S FREQ, THE FIRST CTLR AFTER DEP FROM LGA, HOWEVER THE SUBSEQUENT CTLR DID NOT CATCH THE ERROR WHEN WE CHKED IN AND RPTED CLBING TO 15000 FT. NEITHER MY COPLT (WHO WAS WORKING THE RADIOS) NOR MYSELF (CAPT AND PF) ARE CERTAIN WHOSE ERROR CAUSED THE ALTDEV. THE DEP PHASE IS PARTICULARLY BUSY, AND THIS INCIDENT REINFORCES THE CRITICAL NEED FOR ALL PARTIES TO HEAR AND XCHK ALT CLRNCS AND READBACKS.
