Narrative:
At approximately 15000 ft climbing in icing conditions, south from anc, had been cleared direct to joh VOR and to FL330. Crew experienced a minor electrical malfunction. During checklist compliance with 2 man crew, the en route climb checklist was overlooked (at least the altimeter setting portion). Altimeter setting on the ground was 28.99. Leveled off at FL330. Center promptly asked our altitude and we responded FL330. The center said check your altimeter setting, we have you at 33800 ft. Crew promptly realized our omission, quickly reset and went to proper altitude, thanked the controller and continued. There was no conflict or urgency from the controller. We are standardized quite well on checklist procedures and in 30 yrs flying, this is first excursion of this type. We do not normally fly with 2 pilots, but are somewhat shorthanded and a third not available. I think the distraction of system problem approximately at transition altitude, and the fact that we didn't have our usual set of extra hands and eyes, were both factors, but not excuses. It was simply a mistake/omission that probably and hopefully will not recur. Supplemental information from acn 294799: we received a generator fault alert. We accomplished the applicable checklist items while I flew the aircraft on autoplt. The checklist cleanup was followed by an epcu fault alert (electrical power control unit).
Original NASA ASRS Text
Title: FLT CREW OF ACR OVERSHOOTS ASSIGNED ALT DUE TO FAILURE TO RESET ALTIMETERS CLBING THROUGH FL180.
Narrative: AT APPROX 15000 FT CLBING IN ICING CONDITIONS, S FROM ANC, HAD BEEN CLRED DIRECT TO JOH VOR AND TO FL330. CREW EXPERIENCED A MINOR ELECTRICAL MALFUNCTION. DURING CHKLIST COMPLIANCE WITH 2 MAN CREW, THE ENRTE CLB CHKLIST WAS OVERLOOKED (AT LEAST THE ALTIMETER SETTING PORTION). ALTIMETER SETTING ON THE GND WAS 28.99. LEVELED OFF AT FL330. CTR PROMPTLY ASKED OUR ALT AND WE RESPONDED FL330. THE CTR SAID CHK YOUR ALTIMETER SETTING, WE HAVE YOU AT 33800 FT. CREW PROMPTLY REALIZED OUR OMISSION, QUICKLY RESET AND WENT TO PROPER ALT, THANKED THE CTLR AND CONTINUED. THERE WAS NO CONFLICT OR URGENCY FROM THE CTLR. WE ARE STANDARDIZED QUITE WELL ON CHKLIST PROCS AND IN 30 YRS FLYING, THIS IS FIRST EXCURSION OF THIS TYPE. WE DO NOT NORMALLY FLY WITH 2 PLTS, BUT ARE SOMEWHAT SHORTHANDED AND A THIRD NOT AVAILABLE. I THINK THE DISTR OF SYS PROB APPROX AT TRANSITION ALT, AND THE FACT THAT WE DIDN'T HAVE OUR USUAL SET OF EXTRA HANDS AND EYES, WERE BOTH FACTORS, BUT NOT EXCUSES. IT WAS SIMPLY A MISTAKE/OMISSION THAT PROBABLY AND HOPEFULLY WILL NOT RECUR. SUPPLEMENTAL INFO FROM ACN 294799: WE RECEIVED A GENERATOR FAULT ALERT. WE ACCOMPLISHED THE APPLICABLE CHKLIST ITEMS WHILE I FLEW THE ACFT ON AUTOPLT. THE CHKLIST CLEANUP WAS FOLLOWED BY AN EPCU FAULT ALERT (ELECTRICAL PWR CTL UNIT).
