Narrative:

Mlt X made an initial report from glendale (12 mi northeast of goodyear airport), and was instructed by ATC to report 2 mi east of goodyear airport. Additionally, mlt X was issued traffic on an small aircraft, also inbound from the northeast. When the small aircraft reported in the airport traffic pattern, mlt X was queried as to his location. Mlt X reported north of the airport (instead of east). The controller spotted mlt X, and small aircraft Y (an aircraft flying a west pattern at the airport) was told to go around to avoid conflict with mlt X. The occurrence appears to have resulted from inaccurate position reports.

Original NASA ASRS Text

Title: MLT CREATED A POTENTIAL CONFLICTION WITH ANOTHER ACFT WHILE ENTERING THE TRAFFIC PATTERN.

Narrative: MLT X MADE AN INITIAL REPORT FROM GLENDALE (12 MI NE OF GOODYEAR ARPT), AND WAS INSTRUCTED BY ATC TO REPORT 2 MI E OF GOODYEAR ARPT. ADDITIONALLY, MLT X WAS ISSUED TFC ON AN SMA, ALSO INBND FROM THE NE. WHEN THE SMA REPORTED IN THE ARPT TFC PATTERN, MLT X WAS QUERIED AS TO HIS LOCATION. MLT X REPORTED N OF THE ARPT (INSTEAD OF E). THE CTLR SPOTTED MLT X, AND SMA Y (AN ACFT FLYING A W PATTERN AT THE ARPT) WAS TOLD TO GO AROUND TO AVOID CONFLICT WITH MLT X. THE OCCURRENCE APPEARS TO HAVE RESULTED FROM INACCURATE POSITION REPORTS.
