Narrative:

Small aircraft X was assigned a scapo 3 SID from hillsboro tower. Small aircraft X departed runway 20, should have made a left turn and departed northwesterly. Small aircraft X was radar identified 6 mi south of hillsboro, southbound to the newberg VOR (ubg). There was no conflicting traffic, small aircraft X was vectored on course, to the northwest. I believe the pilot filed his flight plan via ubg, and departed that way, either because his VOR was tuned to it or because of a mind set. Departures from hillsboro are assigned one of three sids. Pilots departing on the wrong SID or on non ATC approved headings are common occurrences.

Original NASA ASRS Text

Title: SMA DID NOT COMPLY WITH ASSIGNED SID HEADING AFTER TKOF.

Narrative: SMA X WAS ASSIGNED A SCAPO 3 SID FROM HILLSBORO TWR. SMA X DEPARTED RWY 20, SHOULD HAVE MADE A LEFT TURN AND DEPARTED NORTHWESTERLY. SMA X WAS RADAR IDENTIFIED 6 MI S OF HILLSBORO, SBND TO THE NEWBERG VOR (UBG). THERE WAS NO CONFLICTING TFC, SMA X WAS VECTORED ON COURSE, TO THE NW. I BELIEVE THE PLT FILED HIS FLT PLAN VIA UBG, AND DEPARTED THAT WAY, EITHER BECAUSE HIS VOR WAS TUNED TO IT OR BECAUSE OF A MIND SET. DEPS FROM HILLSBORO ARE ASSIGNED ONE OF THREE SIDS. PLTS DEPARTING ON THE WRONG SID OR ON NON ATC APPROVED HDGS ARE COMMON OCCURRENCES.
