Narrative:

Generator needed to be reset. While resetting altitude hold/capture unlocked. Were cleared to 11000 ft at 250 KIAS. Captain was anticipating capture and looking for called traffic. I (sic) was changing and resetting radio frequencys from ncs- 31. Both captain and I looked inside to verify altitude capture associated with altitude select chime. Flew through about 300- 400 ft, leveled and nosed over. Had inbound traffic at 12000 ft to about 5 mi. No real excitement with opposing traffic. Had to push aircraft over firmly. Correction area: have departure straight out versus under arrival corridor at near altitudes.

Title: CAPT OF AN ATX LTT JET OVERSHOT CLB ALT BECAUSE THE AUTOPLT CAPTURE WAS NOT ON.

Narrative: GENERATOR NEEDED TO BE RESET. WHILE RESETTING ALT HOLD/CAPTURE UNLOCKED. WERE CLRED TO 11000 FT AT 250 KIAS. CAPT WAS ANTICIPATING CAPTURE AND LOOKING FOR CALLED TFC. I (SIC) WAS CHANGING AND RESETTING RADIO FREQS FROM NCS- 31. BOTH CAPT AND I LOOKED INSIDE TO VERIFY ALT CAPTURE ASSOCIATED WITH ALT SELECT CHIME. FLEW THROUGH ABOUT 300- 400 FT, LEVELED AND NOSED OVER. HAD INBOUND TFC AT 12000 FT TO ABOUT 5 MI. NO REAL EXCITEMENT WITH OPPOSING TFC. HAD TO PUSH ACFT OVER FIRMLY. CORRECTION AREA: HAVE DEP STRAIGHT OUT VERSUS UNDER ARR CORRIDOR AT NEAR ALTS.
