Narrative:
Passenger flight from gtf to geg. Being given radar vectors to final approach course for ILS runway 21 to geg, instructed to descend and maintain 7000 ft. During descent, had some visual contact with ground, and I tried to orient the captain, who was unfamiliar with the area. We became distraction trying to locate felts field (sff) and descended to 6700 ft. Corrected back to 7000 ft and received instruction to descend and maintain 6000 ft. Descended to 5700 ft before correcting back to 6000 ft. Neither of us had shot an approach to spokane, having had visual reference all summer. Expectation of navigation by pilotage and captain's unfamiliarity contributed to distracting attempt to identing landmarks. When not on a visual approach, I need to devote my attention to the instrument procedure, not trying to identify points on the ground. Sterile cockpit would likely have forestalled the problem also.
Original NASA ASRS Text
Title: FO OF AN ACR SMT TURBOPROP OVERSHOT ASSIGNED ALT TWICE DURING DSCNT DUE TO POINTING OUT TERRAIN FEATURES TO THE CAPT INSTEAD OF FLYING THE ACFT.
Narrative: PAX FLT FROM GTF TO GEG. BEING GIVEN RADAR VECTORS TO FINAL APCH COURSE FOR ILS RWY 21 TO GEG, INSTRUCTED TO DSND AND MAINTAIN 7000 FT. DURING DSCNT, HAD SOME VISUAL CONTACT WITH GND, AND I TRIED TO ORIENT THE CAPT, WHO WAS UNFAMILIAR WITH THE AREA. WE BECAME DISTR TRYING TO LOCATE FELTS FIELD (SFF) AND DSNDED TO 6700 FT. CORRECTED BACK TO 7000 FT AND RECEIVED INSTRUCTION TO DSND AND MAINTAIN 6000 FT. DSNDED TO 5700 FT BEFORE CORRECTING BACK TO 6000 FT. NEITHER OF US HAD SHOT AN APCH TO SPOKANE, HAVING HAD VISUAL REF ALL SUMMER. EXPECTATION OF NAV BY PILOTAGE AND CAPT'S UNFAMILIARITY CONTRIBUTED TO DISTRACTING ATTEMPT TO IDENTING LANDMARKS. WHEN NOT ON A VISUAL APCH, I NEED TO DEVOTE MY ATTN TO THE INST PROC, NOT TRYING TO IDENT POINTS ON THE GND. STERILE COCKPIT WOULD LIKELY HAVE FORESTALLED THE PROB ALSO.
