Narrative:

Day 4 of the trip. Previously flew 18 legs in the last 3 days. Our normally scheduled routing to dsm was changed. Our route after cedar rapids was the wrong victor airway -- both pilots missed it. ATC queried us about the mistake. We rechked our flight plan, admitted the mistake and asked if 'we were ok.' they said, 'no problem,' and cleared us direct to dsm. Right before we were handed off to dsm, I asked again if we were ok and they said it was 'dropped at their end.' major contributing factor: fatigue. We are constantly being pushed in this industry to do the most for the least. After reviewing previous NASA forms, I've seen a pattern of mistakes on the last day of a 4 or 5 day trip where fatigue is greatest.

Title: AN SF340B CAPT COMPLAINED THAT FATIGUE WAS A MAJOR CONTRIBUTION TO A TRACK DEV WITH ZAU.

Narrative: DAY 4 OF THE TRIP. PREVIOUSLY FLEW 18 LEGS IN THE LAST 3 DAYS. OUR NORMALLY SCHEDULED ROUTING TO DSM WAS CHANGED. OUR RTE AFTER CEDAR RAPIDS WAS THE WRONG VICTOR AIRWAY -- BOTH PLTS MISSED IT. ATC QUERIED US ABOUT THE MISTAKE. WE RECHKED OUR FLT PLAN, ADMITTED THE MISTAKE AND ASKED IF 'WE WERE OK.' THEY SAID, 'NO PROB,' AND CLRED US DIRECT TO DSM. RIGHT BEFORE WE WERE HANDED OFF TO DSM, I ASKED AGAIN IF WE WERE OK AND THEY SAID IT WAS 'DROPPED AT THEIR END.' MAJOR CONTRIBUTING FACTOR: FATIGUE. WE ARE CONSTANTLY BEING PUSHED IN THIS INDUSTRY TO DO THE MOST FOR THE LEAST. AFTER REVIEWING PREVIOUS NASA FORMS, I'VE SEEN A PATTERN OF MISTAKES ON THE LAST DAY OF A 4 OR 5 DAY TRIP WHERE FATIGUE IS GREATEST.
