Narrative:

I was flying with a flight manager, a flight manager being the equivalent of an assistant chief pilot. This person had flown only 28 hours so far during the current calendar yr. I made the erroneous assumption, that despite the lack of current flight time, his proficiency would be good due to his position. We were climbing to an assigned altitude of 12000 ft MSL. Through 11000 ft I called 1000 ft to go and the altitude alert worked normally. At 11600 ft we were still climbing at approximately 3000 FPM. I mentioned we were approaching our altitude. I'm not sure this input was received by the captain, at 12100 ft I said, 'there's our altitude,' the captain immediately pushed aircraft over. The altitude increased to 12260 ft MSL observed by me. The altitude alert sounded. We returned to 12000 ft MSL. Nothing was said by ATC. I believe this incident happened due to a couple of factors. One being the lack of flying time that flight mgrs receive. My bad assumption that this lack of time would not affect a flight manager as much as a line pilot. Finally my reluctance to speak up as much as I should have, when we were approaching our assigned altitude. I attribute this mostly to the position held by the captain. His method of conducting the flight encouraged input, I assumed he was going to level off, and did not add further input about our rapidly approaching assigned altitude due to my respect for this individual. One final factor, that may or may not be even true, it appeared the captain had difficulty hearing at times, I do not know whether this individual has a hearing problem or not.

Title: ALTDEV ALT OVERSHOT IN CLB.

Narrative: I WAS FLYING WITH A FLT MGR, A FLT MGR BEING THE EQUIVALENT OF AN ASSISTANT CHIEF PLT. THIS PERSON HAD FLOWN ONLY 28 HRS SO FAR DURING THE CURRENT CALENDAR YR. I MADE THE ERRONEOUS ASSUMPTION, THAT DESPITE THE LACK OF CURRENT FLT TIME, HIS PROFICIENCY WOULD BE GOOD DUE TO HIS POS. WE WERE CLBING TO AN ASSIGNED ALT OF 12000 FT MSL. THROUGH 11000 FT I CALLED 1000 FT TO GO AND THE ALT ALERT WORKED NORMALLY. AT 11600 FT WE WERE STILL CLBING AT APPROX 3000 FPM. I MENTIONED WE WERE APCHING OUR ALT. I'M NOT SURE THIS INPUT WAS RECEIVED BY THE CAPT, AT 12100 FT I SAID, 'THERE'S OUR ALT,' THE CAPT IMMEDIATELY PUSHED ACFT OVER. THE ALT INCREASED TO 12260 FT MSL OBSERVED BY ME. THE ALT ALERT SOUNDED. WE RETURNED TO 12000 FT MSL. NOTHING WAS SAID BY ATC. I BELIEVE THIS INCIDENT HAPPENED DUE TO A COUPLE OF FACTORS. ONE BEING THE LACK OF FLYING TIME THAT FLT MGRS RECEIVE. MY BAD ASSUMPTION THAT THIS LACK OF TIME WOULD NOT AFFECT A FLT MGR AS MUCH AS A LINE PLT. FINALLY MY RELUCTANCE TO SPEAK UP AS MUCH AS I SHOULD HAVE, WHEN WE WERE APCHING OUR ASSIGNED ALT. I ATTRIBUTE THIS MOSTLY TO THE POS HELD BY THE CAPT. HIS METHOD OF CONDUCTING THE FLT ENCOURAGED INPUT, I ASSUMED HE WAS GOING TO LEVEL OFF, AND DID NOT ADD FURTHER INPUT ABOUT OUR RAPIDLY APCHING ASSIGNED ALT DUE TO MY RESPECT FOR THIS INDIVIDUAL. ONE FINAL FACTOR, THAT MAY OR MAY NOT BE EVEN TRUE, IT APPEARED THE CAPT HAD DIFFICULTY HEARING AT TIMES, I DO NOT KNOW WHETHER THIS INDIVIDUAL HAS A HEARING PROB OR NOT.
