Narrative:

First officer flying, heading 160 maintain 2000 ft till established cleared for ILS 19. steady on 160 degrees descending to 2000 ft, then 1900 ft. I called altitude, I saw a pitch (up) change, then I turned my attention to helping first officer reset his flight director. Next I knew we were at 1600 ft (not yet on localizer). I took aircraft back to 2000 ft and intercepted GS or localizer then gave first officer the aircraft, he completed approach and landing. Lesson learned, donT allow yourself to get complacent, or distracted. The non-flying pilot is the monitor and when something (altitude) goes wrong, call it then continue to monitor it until itsouth fixed. DonT allow yourself to be distracted.
