Narrative:

Aircraft X was cleared to medford airport via arwy, at 7000'. Non-radar had 3 inbnds already, and was unable to take the new aircraft. Aircraft X was not transponder equipped, and was below radar coverage. Radar controller used DME calls to establish position on arwy, and anticipated approval for aircraft to enter approach control airspace prior to boundary crossing. When boundary was reached, and still unable to approve, aircraft was turned out of airspace and climbed above, but not in time to avoid deviation/error with holding pattern airspace for other inbound. Situation could have been avoided by not issuing clearance to airport in approach control airspace, but rather clear to a point outside of airspace to hold until approved.

Original NASA ASRS Text

Title: ACFT X UNAUTH PENETRATION OF APCH CTL AIRSPACE BY ARTCC.

Narrative: ACFT X WAS CLRED TO MEDFORD ARPT VIA ARWY, AT 7000'. NON-RADAR HAD 3 INBNDS ALREADY, AND WAS UNABLE TO TAKE THE NEW ACFT. ACFT X WAS NOT XPONDER EQUIPPED, AND WAS BELOW RADAR COVERAGE. RADAR CTLR USED DME CALLS TO ESTABLISH POS ON ARWY, AND ANTICIPATED APPROVAL FOR ACFT TO ENTER APCH CTL AIRSPACE PRIOR TO BOUNDARY XING. WHEN BOUNDARY WAS REACHED, AND STILL UNABLE TO APPROVE, ACFT WAS TURNED OUT OF AIRSPACE AND CLBED ABOVE, BUT NOT IN TIME TO AVOID DEV/ERROR WITH HOLDING PATTERN AIRSPACE FOR OTHER INBND. SITUATION COULD HAVE BEEN AVOIDED BY NOT ISSUING CLRNC TO ARPT IN APCH CTL AIRSPACE, BUT RATHER CLR TO A POINT OUTSIDE OF AIRSPACE TO HOLD UNTIL APPROVED.
