Narrative:
During descent to 4000 ft MSL, center cleared us to the OM to hold. Passing 5000 ft, altitude alert sounded and both pilots confirmed 1000 ft to go. We were unable to put the OM in the long range navigation radio, so both pilots had their heads down on the navigation system. The altitude hold didn't catch the altitude at 4000 ft, aircraft descended to 3500 ft. PF caught the altitude just before center. Center stated to 'maintain 4000 ft, I show you at 3500 ft.' we acknowledged and climbed back to 4000 ft. The solution is the PF continues to fly the airplane (have we heard this before?) and the PNF handles the navigation system. No evasive action was taken.
Original NASA ASRS Text
Title: C550 CREW PREOCCUPIED WITH GPS, OVERSHOT ASSIGNED ALT.
Narrative: DURING DSCNT TO 4000 FT MSL, CTR CLRED US TO THE OM TO HOLD. PASSING 5000 FT, ALT ALERT SOUNDED AND BOTH PLTS CONFIRMED 1000 FT TO GO. WE WERE UNABLE TO PUT THE OM IN THE LONG RANGE NAV RADIO, SO BOTH PLTS HAD THEIR HEADS DOWN ON THE NAV SYS. THE ALT HOLD DIDN'T CATCH THE ALT AT 4000 FT, ACFT DSNDED TO 3500 FT. PF CAUGHT THE ALT JUST BEFORE CTR. CTR STATED TO 'MAINTAIN 4000 FT, I SHOW YOU AT 3500 FT.' WE ACKNOWLEDGED AND CLBED BACK TO 4000 FT. THE SOLUTION IS THE PF CONTINUES TO FLY THE AIRPLANE (HAVE WE HEARD THIS BEFORE?) AND THE PNF HANDLES THE NAV SYS. NO EVASIVE ACTION WAS TAKEN.
