## Discrepancy

PART WAS TO REPLACE ANOTHER PART NOW IDENTIFIED AS A SUSPECTED UNAPPROVED PART (SUP). SERIAL NUMBER CT-207 DOES NOT MEET THE REQUIREMENTS OF AN APPROVED PART: INCOMPLETE PAPERWORK, IDENTIFICATION MARKINGS, AND QUESTIONABLE INDICATION OF MANUFACTURE HISTORY. THE FSDO CONTACTED THE MANUFACTURER SUSPECTED UNAPPROVED PARTS DIVISION AND COULD NOT ESTABLISH THAT CT-207 IS A PART MANUFACTURED BY THEM.
