Narrative:
On descent into msp, our FMS was on mco, so workload was a little higher and our normal habit pattern was broken. While turning to intercept a radial, descending, and running the approach checks, I broke 10000 ft before slowing to 250 KTS. The captain caught it and, right away, we leveled off around 9700 ft and slowed before continuing the descent. This event underscores the importance of PNF duties and how you need to be extra vigilant when your workload increases, or if your habit pattern is broken.

Title: RESOLVING AN INCORRECT FMS INPUT, MD88 FLT CREW DSND BELOW 10000 FT IN EXCESS OF 250 KTS, BEFORE CAPT RECOGNIZES ERROR WHILE ON APCH TO MSP.
Narrative: ON DSCNT INTO MSP, OUR FMS WAS ON MCO, SO WORKLOAD WAS A LITTLE HIGHER AND OUR NORMAL HABIT PATTERN WAS BROKEN. WHILE TURNING TO INTERCEPT A RADIAL, DSNDING, AND RUNNING THE APCH CHKS, I BROKE 10000 FT BEFORE SLOWING TO 250 KTS. THE CAPT CAUGHT IT AND, RIGHT AWAY, WE LEVELED OFF AROUND 9700 FT AND SLOWED BEFORE CONTINUING THE DSCNT. THIS EVENT UNDERSCORES THE IMPORTANCE OF PNF DUTIES AND HOW YOU NEED TO BE EXTRA VIGILANT WHEN YOUR WORKLOAD INCREASES, OR IF YOUR HABIT PATTERN IS BROKEN.
