Narrative:

Arrival step downs to geg cleared to 7000 ft. Captain was flying. We both acknowledged and pointed to altimeter as per air carrier procedure. I was briefing passenger and noticed altimeter was 6500 ft. I alerted captain and we corrected to 7000 ft. No comment from ATC. We were on last leg of trip following a reduced rest overnight preceded by a long day. We were tired! I believe our schedules are often too demanding and do not provide enough rest. The only reason there are not more fatigue related accidents is because of the professional and heroic job being done by pilots in this country. How can we be expected to be safe after long days and short nights? I will try to avoid other duties during last 1000 ft of all climbs and dscnts to keep this from happening again.

Title: ALT OVERSHOOT ON DSCNT.

Narrative: ARR STEP DOWNS TO GEG CLRED TO 7000 FT. CAPT WAS FLYING. WE BOTH ACKNOWLEDGED AND POINTED TO ALTIMETER AS PER ACR PROC. I WAS BRIEFING PAX AND NOTICED ALTIMETER WAS 6500 FT. I ALERTED CAPT AND WE CORRECTED TO 7000 FT. NO COMMENT FROM ATC. WE WERE ON LAST LEG OF TRIP FOLLOWING A REDUCED REST OVERNIGHT PRECEDED BY A LONG DAY. WE WERE TIRED! I BELIEVE OUR SCHEDULES ARE OFTEN TOO DEMANDING AND DO NOT PROVIDE ENOUGH REST. THE ONLY REASON THERE ARE NOT MORE FATIGUE RELATED ACCIDENTS IS BECAUSE OF THE PROFESSIONAL AND HEROIC JOB BEING DONE BY PLTS IN THIS COUNTRY. HOW CAN WE BE EXPECTED TO BE SAFE AFTER LONG DAYS AND SHORT NIGHTS? I WILL TRY TO AVOID OTHER DUTIES DURING LAST 1000 FT OF ALL CLBS AND DSCNTS TO KEEP THIS FROM HAPPENING AGAIN.
