Narrative:

A pre departure clearance was given to the crew. The seattle mountain 3 departure was printed on the computer paper, but was in the folded area and was missed. The captain and I then assumed we were on the seattle VFR departure and climbed out runway heading instead of turning automatically to 090 degree at 8 DME. Departure control gave us a heading of 090 degree about 10 DME. Departure control did not specifically mention a problem, but he did tell the following aircraft to delay his 090 degree turn to stay behind us. We looked at the pre departure clearance again and realized the mountain 3 departure was printed, but assumed no conflict occurred.

Original NASA ASRS Text

Title: PDC SID ASSIGNMENT WAS OVERLOOKED RESULTING IN TRACK DEV.

Narrative: A PDC WAS GIVEN TO THE CREW. THE SEATTLE MOUNTAIN 3 DEP WAS PRINTED ON THE COMPUTER PAPER, BUT WAS IN THE FOLDED AREA AND WAS MISSED. THE CAPT AND I THEN ASSUMED WE WERE ON THE SEATTLE VFR DEP AND CLBED OUT RWY HDG INSTEAD OF TURNING AUTOMATICALLY TO 090 DEG AT 8 DME. DEP CTL GAVE US A HDG OF 090 DEG ABOUT 10 DME. DEP CTL DID NOT SPECIFICALLY MENTION A PROB, BUT HE DID TELL THE FOLLOWING ACFT TO DELAY HIS 090 DEG TURN TO STAY BEHIND US. WE LOOKED AT THE PDC AGAIN AND REALIZED THE MOUNTAIN 3 DEP WAS PRINTED, BUT ASSUMED NO CONFLICT OCCURRED.
