AIR TAXI SMT CLBS ABOVE ASSIGNED ALT.

Narrative

ON A FEDERAL PRISON CHARTER FROM ANB TO SGF. DEPARTED ANB WITH 1 PRISONER AND 3 STAFF. CLBED OUT AND HANDED OFF TO ZTL ON 134.95. WAS GIVEN 10000 FT AS MY ALT. AT 9000 FT A STAFF MEMBER ASKED ME IF HE COULD GET UP TO ATTEND TO PRISONER. I SAID IT WAS OK. IT WAS SMOOTH AND CLR. RESUMED FLYING AT 11800 FT REALIZED 10000 FT WAS CLB LIMIT (FINAL ALT WAS TO BE 16000 FT). STOPPED CLB. INITIATED CALL TO CTR. THEY CALLED FIRST AND ASKED ASSIGNED ALT. I SAID IT WAS 10000 FT; SORRY. I WAS TOLD TO MAINTAIN PRESENT ALT AND WAS HANDED OFF TO NEXT CTLR ON 134.05. I WAS THEN GIVEN CLB TO 16000 FT. SHOULD NOT HAVE SPOKEN TO PAX UNTIL LEVEL OFF; ALTHOUGH I STILL SHOULD HAVE CAUGHT THIS. SOME MEDICAL PROBS WITH SOME FAMILY MEMBERS ON MY MIND. COMBINATION OF THESE CONTRIBUTED TO ME MISSING CLB LIMIT ALONG WITH 16000 FT AS FINAL IN MY MIND. WHEN I DON'T HAVE TO USE ADF; I DIAL IN ASSIGNED ALTS AS A REMINDER. NEED TO GET SEPARATE ALT ALERTER OR WRITE DOWN ALTS IN DIFFERENT PLACE. ALL IN ALL; I SCREWED UP. THERE WAS NO CONFLICT TO MY KNOWLEDGE AND I WAS NOT INFORMED OF ANY. BEFORE I MAILED THIS; CALLED ATL QUALITY ASSURANCE. EVIDENTLY; THERE WAS A CONFLICT BUT HE COULDN'T TELL ME HOW CLOSE OR WHO OR WHAT IT WAS.
