Narrative:

Pre departure clearance to 5000 ft. In the climb I called out '4000 ft for 5000 ft,' reduced the power, and was climbing out at about 800 FPM. I got engrossed in the trim of the aircraft. My scan was not on the altitude. Supplemental information from acn 341687: our flight departed ord for mci and while being radar vectored on the initial climb, we discussed the virga and potential need to deviate around a cell. Approaching 5000 ft, I observed the pitch attitude decreasing and apparent leveloff. I reached down to adjust the radar set. A few moments later I noticed the altimeter indicating 5200 ft and the aircraft climbing. I reacted by pushing the yoke and stating, 'watch your altitude.' at approximately the same time, the altitude alert sounded and the first officer simultaneously pushed the yoke forward and closed the throttles. Climb was arrested. Controller did not say anything about the altitude deviation leading us to believe he was unaware of it.

Title: AN ACR MLG FLC OVERSHOT THEIR ASSIGNED ALT DURING THE DEP CLB. THE ERROR WAS DETECTED BY THE PNF AND THE ALT ALERTER. THE PF WAS DISTR TASK TRIM.

Narrative: PDC TO 5000 FT. IN THE CLB I CALLED OUT '4000 FT FOR 5000 FT,' REDUCED THE PWR, AND WAS CLBING OUT AT ABOUT 800 FPM. I GOT ENGROSSED IN THE TRIM OF THE ACFT. MY SCAN WAS NOT ON THE ALT. SUPPLEMENTAL INFO FROM ACN 341687: OUR FLT DEPARTED ORD FOR MCI AND WHILE BEING RADAR VECTORED ON THE INITIAL CLB, WE DISCUSSED THE VIRGA AND POTENTIAL NEED TO DEVIATE AROUND A CELL. APCHING 5000 FT, I OBSERVED THE PITCH ATTITUDE DECREASING AND APPARENT LEVELOFF. I REACHED DOWN TO ADJUST THE RADAR SET. A FEW MOMENTS LATER I NOTICED THE ALTIMETER INDICATING 5200 FT AND THE ACFT CLBING. I REACTED BY PUSHING THE YOKE AND STATING, 'WATCH YOUR ALT.' AT APPROX THE SAME TIME, THE ALT ALERT SOUNDED AND THE FO SIMULTANEOUSLY PUSHED THE YOKE FORWARD AND CLOSED THE THROTTLES. CLB WAS ARRESTED. CTLR DID NOT SAY ANYTHING ABOUT THE ALTDEV LEADING US TO BELIEVE HE WAS UNAWARE OF IT.
