Narrative:
We were cleared to 9000 ft from an altitude in the teens. I was in the middle of briefing the approach as we were descending. Apparently both our heads were down at the same time. The altitude reminder went off, telling us that we had 1000 ft to go. I immediately realized that I was about to exceed the 250 KT speed restr. I immediately slowed down and continued without incident. Moral of the story: never have all the pilots' heads down at the same time. Someone must always be minding the store. It's also helpful to do the approach briefing before descending through 10000 ft at a non busy time of the flight.
Original NASA ASRS Text
Title: CAPT OF AN MLG EXCEEDED THE AIRSPD RESTR BELOW 10000 FT DURING DSCNT ARR DUE TO BEING DISTR IN APCH COCKPIT BRIEFING.
Narrative: WE WERE CLRED TO 9000 FT FROM AN ALT IN THE TEENS. I WAS IN THE MIDDLE OF BRIEFING THE APCH AS WE WERE DSNDING. APPARENTLY BOTH OUR HEADS WERE DOWN AT THE SAME TIME. THE ALT REMINDER WENT OFF, TELLING US THAT WE HAD 1000 FT TO GO. I IMMEDIATELY REALIZED THAT I WAS ABOUT TO EXCEED THE 250 KT SPD RESTR. I IMMEDIATELY SLOWED DOWN AND CONTINUED WITHOUT INCIDENT. MORAL OF THE STORY: NEVER HAVE ALL THE PLTS' HEADS DOWN AT THE SAME TIME. SOMEONE MUST ALWAYS BE MINDING THE STORE. IT'S ALSO HELPFUL TO DO THE APCH BRIEFING BEFORE DSNDING THROUGH 10000 FT AT A NON BUSY TIME OF THE FLT.
