Flight crew of a british jetstream 4100 BA41 overshot climb altitude after takeoff. First officer missed resetting the cleared altitude in the alerter. ATC intervened and questioned them on their assigned altitude since turboprop aircraft usually are given a lower altitude than the SID indicates. The first officer only remembered amended altitude after ATC's inquiry.

Narrative:
During taxi out with FAA in jump seat, I verified the altitude in the altitude select window with the first officer by saying 'is 5000 ft the initial?' first officer responded, 'yes, 5000 ft is the initial.' I briefed takeoff to be my leg including, again, the initial altitude of 5000 ft. Directly after takeoff, tower instructed us to maintain visual contact with the DC9 and contact departure. Climbing through 4200 ft for 5000 ft departure asked 'what is your assigned altitude?' first officer '5000 ft.' departure, 'do you have the DC9 in sight?' first officer, 'affirmative.' departure then gave us a routine turnout and cleared us to 14000 ft and explained to us that clearance normally gives turboprops 3000 ft and jets 5000 ft. After arriving in stl and after the FAA jumpseater left the airplane I asked the first officer what she wrote down. She responded 3000 ft and explained that we were cleared via the mem 5 which has published 5000 ft. We had blown the amended initial altitude of 3000 ft! I was not in the aircraft when the first officer picked up clearance so I did not hear clearance issue 3000 ft. The SID only includes 5000 ft. If clearance routinely issues 3000 ft to turboprop aircraft, it would help to just say that on the SID.
Original NASA ASRS Text
Title: FLC OF A BRITISH JETSTREAM 4100 BA41 OVERSHOT CLB ALT AFTER TKOF. FO MISSED RESETTING THE CLRED ALT IN THE ALERTER. ATC INTERVENED AND QUESTIONED THEM ON THEIR ASSIGNED ALT SINCE TURBOPROP ACFT USUALLY ARE GIVEN A LOWER ALT THAN THE SID INDICATES. THE FO ONLY REMEMBERED AMENDED ALT AFTER ATC'S INQUIRY.
Narrative: DURING TAXI OUT WITH FAA IN JUMP SEAT, I VERIFIED THE ALT IN THE ALT SELECT WINDOW WITH THE FO BY SAYING 'IS 5000 FT THE INITIAL?' FO RESPONDED, 'YES, 5000 FT IS THE INITIAL.' I BRIEFED TKOF TO BE MY LEG INCLUDING, AGAIN, THE INITIAL ALT OF 5000 FT. DIRECTLY AFTER TKOF, TWR INSTRUCTED US TO MAINTAIN VISUAL CONTACT WITH THE DC9 AND CONTACT DEP. CLBING THROUGH 4200 FT FOR 5000 FT DEP ASKED 'WHAT IS YOUR ASSIGNED ALT?' FO '5000 FT.' DEP, 'DO YOU HAVE THE DC9 IN SIGHT?' FO, 'AFFIRMATIVE.' DEP THEN GAVE US A ROUTINE TURNOUT AND CLRED US TO 14000 FT AND EXPLAINED TO US THAT CLRNC NORMALLY GIVES TURBOPROPS 3000 FT AND JETS 5000 FT. AFTER ARRIVING IN STL AND AFTER THE FAA JUMPSEATER LEFT THE AIRPLANE I ASKED THE FO WHAT SHE WROTE DOWN. SHE RESPONDED 3000 FT AND EXPLAINED THAT WE WERE CLRED VIA THE MEM 5 WHICH HAS PUBLISHED 5000 FT. WE HAD BLOWN THE AMENDED INITIAL ALT OF 3000 FT! I WAS NOT IN THE ACFT WHEN THE FO PICKED UP CLRNC SO I DID NOT HEAR CLRNC ISSUE 3000 FT. THE SID ONLY INCLUDES 5000 FT. IF CLRNC ROUTINELY ISSUES 3000 FT TO TURBOPROP ACFT, IT WOULD HELP TO JUST SAY THAT ON THE SID.
