Narrative:

We were climbing to 8000 ft MSL. Center gave us a clearance to intercept an airway off a discontinuity on the FMS. My first officer was not sure how to set up the intercept so we both worked on the problem. The aircraft was on autoplt and programmed to intercept and level off at 8000 ft. Unfortunately; the aircraft has no autothrottles. While we were working the FMS problem; the aircraft leveled off at 8000 ft and proceeded to accelerate. When my first officer looked up; we were in excess of 300 KIAS. I immediately closed the thrust levers and slowed back down to 250 KIAS. Center said nothing about our speed. I; as the PF and captain; am totally responsible for this. It was my job to either fly the plane and let the first officer figure the problem out or to xfer the controls and do the intercept. We ended up both of us heads down inside the cockpit with no one monitoring the flight. This is an outstanding example of lack of CRM and will not happen again in my cockpit.

Title: DISTRACTED BY UNFAMILIAR FMS PROGRAMMING FOR AN ATC CLRNC; CARJ FLT CREW FAILS TO MONITOR LEVEL OFF AT 8000 FT MSL AND ACFT ACCELERATES TO 300 KIAS.

Narrative: WE WERE CLBING TO 8000 FT MSL. CTR GAVE US A CLRNC TO INTERCEPT AN AIRWAY OFF A DISCONTINUITY ON THE FMS. MY FO WAS NOT SURE HOW TO SET UP THE INTERCEPT SO WE BOTH WORKED ON THE PROB. THE ACFT WAS ON AUTOPLT AND PROGRAMMED TO INTERCEPT AND LEVEL OFF AT 8000 FT. UNFORTUNATELY; THE ACFT HAS NO AUTOTHROTTLES. WHILE WE WERE WORKING THE FMS PROB; THE ACFT LEVELED OFF AT 8000 FT AND PROCEEDED TO ACCELERATE. WHEN MY FO LOOKED UP; WE WERE IN EXCESS OF 300 KIAS. I IMMEDIATELY CLOSED THE THRUST LEVERS AND SLOWED BACK DOWN TO 250 KIAS. CTR SAID NOTHING ABOUT OUR SPD. I; AS THE PF AND CAPT; AM TOTALLY RESPONSIBLE FOR THIS. IT WAS MY JOB TO EITHER FLY THE PLANE AND LET THE FO FIGURE THE PROB OUT OR TO XFER THE CTLS AND DO THE INTERCEPT. WE ENDED UP BOTH OF US HEADS DOWN INSIDE THE COCKPIT WITH NO ONE MONITORING THE FLT. THIS IS AN OUTSTANDING EXAMPLE OF LACK OF CRM AND WILL NOT HAPPEN AGAIN IN MY COCKPIT.
