Narrative:

While departing mdw, we were level at 4000 ft and cleared to 6000 ft. I called for climb power and climbed to 6000 ft. Climbing through 5000 ft, I was momentarily distraction. When I looked back at my altimeter and vertical speed we were climbing rapidly to 6000 ft. I pulled the power off and nosed over and had ended up at 6200 ft and quickly descended back down to 6000 ft. I was partly distraction by the ADI in this particular aircraft. This is the only aircraft in the fleet with a large ADI, most of our B727 have a very small ADI. I felt like we had a higher pitch than normal because of the more detailed pitch increments. Also, I should not have called for climb power with the aircraft being so light. This combination led to this and I should not have allowed it to happen.

Original NASA ASRS Text

Title: B727 CREW HAD ALT OVERSHOOT IN C90 CLASS B AIRSPACE.

Narrative: WHILE DEPARTING MDW, WE WERE LEVEL AT 4000 FT AND CLRED TO 6000 FT. I CALLED FOR CLB PWR AND CLBED TO 6000 FT. CLBING THROUGH 5000 FT, I WAS MOMENTARILY DISTR. WHEN I LOOKED BACK AT MY ALTIMETER AND VERT SPD WE WERE CLBING RAPIDLY TO 6000 FT. I PULLED THE PWR OFF AND NOSED OVER AND HAD ENDED UP AT 6200 FT AND QUICKLY DSNDED BACK DOWN TO 6000 FT. I WAS PARTLY DISTR BY THE ADI IN THIS PARTICULAR ACFT. THIS IS THE ONLY ACFT IN THE FLEET WITH A LARGE ADI, MOST OF OUR B727 HAVE A VERY SMALL ADI. I FELT LIKE WE HAD A HIGHER PITCH THAN NORMAL BECAUSE OF THE MORE DETAILED PITCH INCREMENTS. ALSO, I SHOULD NOT HAVE CALLED FOR CLB PWR WITH THE ACFT BEING SO LIGHT. THIS COMBINATION LED TO THIS AND I SHOULD NOT HAVE ALLOWED IT TO HAPPEN.
