Narrative:

During initial climb to cruise altitude (FL200), I failed to level off at the assigned altitude. Passing through FL203, I recognized the deviation and began the immediate descent back to the assigned altitude of FL200. Shortly after I noticed the deviation and began correction action, the controller (ZJX) questioned our altitude. The PNF responded that we had been off altitude and were correcting. The second transmission from ZJX informed us that there was another aircraft at FL210 and we would need to be leveled off in the next 30 seconds to avoid a conflict. By the time this transmission ended, we were already level at FL200. The obvious cause of this deviation was inattn on the part of me. The breakdown was corrected initially by the altitude alerter that initially alerted us of the problem and then by the ZJX controller who not only alerted us of the deviation, but informed us of another aircraft that would become a conflict situation.

Original NASA ASRS Text

Title: B190 FLC OVERSHOT LEVELING AT CRUISE ALT.

Narrative: DURING INITIAL CLB TO CRUISE ALT (FL200), I FAILED TO LEVEL OFF AT THE ASSIGNED ALT. PASSING THROUGH FL203, I RECOGNIZED THE DEV AND BEGAN THE IMMEDIATE DSCNT BACK TO THE ASSIGNED ALT OF FL200. SHORTLY AFTER I NOTICED THE DEV AND BEGAN CORRECTION ACTION, THE CTLR (ZJX) QUESTIONED OUR ALT. THE PNF RESPONDED THAT WE HAD BEEN OFF ALT AND WERE CORRECTING. THE SECOND XMISSION FROM ZJX INFORMED US THAT THERE WAS ANOTHER ACFT AT FL210 AND WE WOULD NEED TO BE LEVELED OFF IN THE NEXT 30 SECONDS TO AVOID A CONFLICT. BY THE TIME THIS XMISSION ENDED, WE WERE ALREADY LEVEL AT FL200. THE OBVIOUS CAUSE OF THIS DEV WAS INATTN ON THE PART OF ME. THE BREAKDOWN WAS CORRECTED INITIALLY BY THE ALT ALERTER THAT INITIALLY ALERTED US OF THE PROB AND THEN BY THE ZJX CTLR WHO NOT ONLY ALERTED US OF THE DEV, BUT INFORMED US OF ANOTHER ACFT THAT WOULD BECOME A CONFLICT SIT.
