Narrative:

First leg sequence hand flying -- avoiding thunderstorms -- rapid descent to 3000 ft in rain nearing localizer caught descent at 3000 ft at 2000 FPM. Arrested descent rate at 2700 ft, smoothly returned to 3000 ft. No conflict (TCASII or otherwise). Many things going on, setting up approach, altitude change, new captain, and nearing localizer. Just lost track of altitude for a moment. Solution -- fly aircraft first -- dispatchers second -- even third.

Title: ACR MLG DSNDING TO 3000 FT 10 MI W OF RQR, HAND FLYING, OVERSHOT ALT 300 FT ACCOUNT HIGH DSCNT RATE. REGAINED ALT WITHOUT ANY COMMENT FROM CTLR.

Narrative: FIRST LEG SEQUENCE HAND FLYING -- AVOIDING TSTMS -- RAPID DSCNT TO 3000 FT IN RAIN NEARING LOC CAUGHT DSCNT AT 3000 FT AT 2000 FPM. ARRESTED DSCNT RATE AT 2700 FT, SMOOTHLY RETURNED TO 3000 FT. NO CONFLICT (TCASII OR OTHERWISE). MANY THINGS GOING ON, SETTING UP APCH, ALT CHANGE, NEW CAPT, AND NEARING LOC. JUST LOST TRACK OF ALT FOR A MOMENT. SOLUTION -- FLY ACFT FIRST -- DISPATCHERS SECOND -- EVEN THIRD.
