Narrative:

We were cleared to descend to 9000 ft. Upon reaching 9000 ft, the captain and I both noticed that we were exceeding 250 KTS. We began to slow the aircraft at which time ATC advised us to execute a right 360 degree turn to reintercept the arrival. We were in the process of completing the descent check, but we should have both been paying more attention to flying the airplane. Supplemental information from acn 406420: I think this occurred due to the flight crew's lack of sleep the night before on a reduced rest overnight with only 8 hours off duty.

Title: CL65 CREW EXCEEDS MAX AIRSPD BELOW 10000 FT IN MCO AIRSPACE.

Narrative: WE WERE CLRED TO DSND TO 9000 FT. UPON REACHING 9000 FT, THE CAPT AND I BOTH NOTICED THAT WE WERE EXCEEDING 250 KTS. WE BEGAN TO SLOW THE ACFT AT WHICH TIME ATC ADVISED US TO EXECUTE A R 360 DEG TURN TO REINTERCEPT THE ARR. WE WERE IN THE PROCESS OF COMPLETING THE DSCNT CHK, BUT WE SHOULD HAVE BOTH BEEN PAYING MORE ATTN TO FLYING THE AIRPLANE. SUPPLEMENTAL INFO FROM ACN 406420: I THINK THIS OCCURRED DUE TO THE FLC'S LACK OF SLEEP THE NIGHT BEFORE ON A REDUCED REST OVERNIGHT WITH ONLY 8 HRS OFF DUTY.
