Narrative:
Aircraft departed fok and was cleared to climb and maintain 8000 ft. Going through 7000 ft crew heard a new clearance to FL280 and read back 'cleared to climb to FL280.' departure control never came back to correct the wrong readback. Upon going through 9500 ft departure control advised us to maintain 2000 ft. We descended back to 8000 ft. (Actually they had given us a 280 degree heading.) no conflict with any other aircraft. Suggestion: controllers should listen to what flcs read back so when a wrong readback is done, it can be corrected before a conflict arises. Flcs should question it when a controller gives a new clearance and does not acknowledge your 'readback.'
Original NASA ASRS Text
Title: FLC OF A GULFSTREAM 1159 OVERSHOT CLB ALT DUE TO A MISUNDERSTANDING OF AN AIRSPD LIMITATION FOR A NEW ALT ASSIGNMENT.
Narrative: ACFT DEPARTED FOK AND WAS CLRED TO CLB AND MAINTAIN 8000 FT. GOING THROUGH 7000 FT CREW HEARD A NEW CLRNC TO FL280 AND READ BACK 'CLRED TO CLB TO FL280.' DEP CTL NEVER CAME BACK TO CORRECT THE WRONG READBACK. UPON GOING THROUGH 9500 FT DEP CTL ADVISED US TO MAINTAIN 2000 FT. WE DSNDED BACK TO 8000 FT. (ACTUALLY THEY HAD GIVEN US A 280 DEG HDG.) NO CONFLICT WITH ANY OTHER ACFT. SUGGESTION: CTLRS SHOULD LISTEN TO WHAT FLCS READ BACK SO WHEN A WRONG READBACK IS DONE, IT CAN BE CORRECTED BEFORE A CONFLICT ARISES. FLCS SHOULD QUESTION IT WHEN A CTLR GIVES A NEW CLRNC AND DOES NOT ACKNOWLEDGE YOUR 'READBACK.'
