Narrative:

Fairly new, inexperienced first officer was flying aircraft. Autoplt was engaged. We were level at FL310 and received a climb clearance to FL330. The first officer engaged the flight level change mode (speed mode) and increased power to mct. In an attempt to maintain the selected speed, the aircraft pitched up to a rate of climb of about 3500 FPM. Because the altitude change required was only 2000 ft, the aircraft exceeded the assigned altitude before the automatic system could correct for the excessive climb rate. We climbed to an altitude of approximately 33,350 ft. The autoplt was reacting too slowly, so we disconnected it, and hand flew back down to FL330. The incident happened because the first officer did not understand the capabilities of the aircraft, and also because the PIC did not sufficiently monitor his actions.

Original NASA ASRS Text

Title: LJ45 OVERSHOT A 2000 FT ALT CHANGE.

Narrative: FAIRLY NEW, INEXPERIENCED FO WAS FLYING ACFT. AUTOPLT WAS ENGAGED. WE WERE LEVEL AT FL310 AND RECEIVED A CLB CLRNC TO FL330. THE FO ENGAGED THE FLT LEVEL CHANGE MODE (SPD MODE) AND INCREASED PWR TO MCT. IN AN ATTEMPT TO MAINTAIN THE SELECTED SPD, THE ACFT PITCHED UP TO A RATE OF CLB OF ABOUT 3500 FPM. BECAUSE THE ALT CHANGE REQUIRED WAS ONLY 2000 FT, THE ACFT EXCEEDED THE ASSIGNED ALT BEFORE THE AUTO SYS COULD CORRECT FOR THE EXCESSIVE CLB RATE. WE CLBED TO AN ALT OF APPROX 33,350 FT. THE AUTOPLT WAS REACTING TOO SLOWLY, SO WE DISCONNECTED IT, AND HAND FLEW BACK DOWN TO FL330. THE INCIDENT HAPPENED BECAUSE THE FO DID NOT UNDERSTAND THE CAPABILITIES OF THE ACFT, AND ALSO BECAUSE THE PIC DID NOT SUFFICIENTLY MONITOR HIS ACTIONS.
