Narrative:
Approximately 5 mins after leveling at FL410 the ZJX controller asked us to 'say altitude.' the first officer replied, 'level at FL410.' the controller then advised us that he showed us 400 ft low and to 'check our altimeter setting.' our altimeters (all 3) were still set for climb below FL180. We immediately reset our altimeters and corrected our altitude. Upon reviewing our actions, we realized we didn't complete our transition level checklists (FL180) because the first officer received a route change from ATC and began reprogramming our FMS while we were climbing through 17000 ft. We were both busy and tired, and just deviated from our SOP. We had an early morning reservation into dab and both spent the day at the race track. After the race was over and our passenger returned to the airport, we boarded the aircraft. After starting our taxi it took 2 hours to taxi, get our clearance and get to the end of the runway. This delay and our day's schedule, I feel led to some additional fatigue. I think these were all contributing factors to this event.
Original NASA ASRS Text
Title: A C560 CPR JET LEVELS OFF 400 FT TOO LOW IN CRUISE. ITS ALTIMETERS WERE NOT SET TO 29 PT 92 AT FL180 AS REQUIRED.
Narrative: APPROX 5 MINS AFTER LEVELING AT FL410 THE ZJX CTLR ASKED US TO 'SAY ALT.' THE FO REPLIED, 'LEVEL AT FL410.' THE CTLR THEN ADVISED US THAT HE SHOWED US 400 FT LOW AND TO 'CHK OUR ALTIMETER SETTING.' OUR ALTIMETERS (ALL 3) WERE STILL SET FOR CLB BELOW FL180. WE IMMEDIATELY RESET OUR ALTIMETERS AND CORRECTED OUR ALT. UPON REVIEWING OUR ACTIONS, WE REALIZED WE DIDN'T COMPLETE OUR TRANSITION LEVEL CHKLISTS (FL180) BECAUSE THE FO RECEIVED A RTE CHANGE FROM ATC AND BEGAN REPROGRAMMING OUR FMS WHILE WE WERE CLBING THROUGH 17000 FT. WE WERE BOTH BUSY AND TIRED, AND JUST DEVIATED FROM OUR SOP. WE HAD AN EARLY MORNING RESERVATION INTO DAB AND BOTH SPENT THE DAY AT THE RACE TRACK. AFTER THE RACE WAS OVER AND OUR PAX RETURNED TO THE ARPT, WE BOARDED THE ACFT. AFTER STARTING OUR TAXI IT TOOK 2 HRS TO TAXI, GET OUR CLRNC AND GET TO THE END OF THE RWY. THIS DELAY AND OUR DAY'S SCHEDULE, I FEEL LED TO SOME ADDITIONAL FATIGUE. I THINK THESE WERE ALL CONTRIBUTING FACTORS TO THIS EVENT.
