Narrative:

While flying on vectors after departure, we were initially cleared to 3000 ft. The first officer left frequency after a change in heading and what I thought was a clearance to 10000 ft. The first officer sometimes forgets to change the altitude alerter and I climbed through 3000 ft as the alerter went off. I immediately verified our clearance altitude as 10000 ft. I believe that both pilots should confirm a new altitude and the PNF should immediately dial the altitude in the alerter. For example after a clearance to climb 10000 ft, the PNF should dial this in the alerter and the PF should verbally verify the new altitude. The first officer in this case learned that flying the aircraft comes first.

Original NASA ASRS Text

Title: A C550 CRUISING AT 3000 FT STARTS A CLB TO 10000 FT WITHOUT CLRNC FROM CMH, OH, DEP CTL.

Narrative: WHILE FLYING ON VECTORS AFTER DEP, WE WERE INITIALLY CLRED TO 3000 FT. THE FO LEFT FREQ AFTER A CHANGE IN HEADING AND WHAT I THOUGHT WAS A CLRNC TO 10000 FT. THE FO SOMETIMES FORGETS TO CHANGE THE ALT ALERTER AND I CLBED THROUGH 3000 FT AS THE ALERTER WENT OFF. I IMMEDIATELY VERIFIED OUR CLRNC ALT AS 10000 FT. I BELIEVE THAT BOTH PLTS SHOULD CONFIRM A NEW ALT AND THE PNF SHOULD IMMEDIATELY DIAL THE ALT IN THE ALERTER. FOR EXAMPLE AFTER A CLRNC TO CLB 10000 FT, THE PNF SHOULD DIAL THIS IN THE ALERTER AND THE PF SHOULD VERBALLY VERIFY THE NEW ALT. THE FO IN THIS CASE LEARNED THAT FLYING THE ACFT COMES FIRST.
