Narrative:

Pre departure clearance was not available through ACARS. Due to saturation on clearance delivery frequency, we received our clearance on taxi-out. I was monitoring ramp control while the first officer copied the clearance. We failed to detect a change in the routing. Our proposed routing was txk J-131 lit J-66 mem and our actual clearance was txk J-42 mem. After txk, the routing confusion resulted and we were then cleared direct mem. This underscores the necessity for both pilots to monitor and check the actual clearance received.

Original NASA ASRS Text

Title: ACR X NON ADHERENCE TO ATC CLRNC RTE DEV.

Narrative: PDC WAS NOT AVAILABLE THROUGH ACARS. DUE TO SATURATION ON CLRNC DELIVERY FREQ, WE RECEIVED OUR CLRNC ON TAXI-OUT. I WAS MONITORING RAMP CTL WHILE THE FO COPIED THE CLRNC. WE FAILED TO DETECT A CHANGE IN THE ROUTING. OUR PROPOSED ROUTING WAS TXK J-131 LIT J-66 MEM AND OUR ACTUAL CLRNC WAS TXK J-42 MEM. AFTER TXK, THE ROUTING CONFUSION RESULTED AND WE WERE THEN CLRED DIRECT MEM. THIS UNDERSCORES THE NECESSITY FOR BOTH PLTS TO MONITOR AND CHK THE ACTUAL CLRNC RECEIVED.
