Information received during a Federal Aviation Administration (FAA) Suspected Unapproved Parts (SUP) investigation revealed that WECO Aerospace Systems, Inc., located at 1501 Aviation Boulevard, Lincoln, California 95648, maintained and approved for return to service various aircraft components and instruments contrary to regulations. WECO, Inc., formerly held FAA Air Agency Certificate No. UQ3R902L.
Evidence indicates WECO approved for return to service components and instruments not maintained in compliance with the manufacturer’s maintenance manual or other data acceptable to the FAA. WECO failed to accomplish specified tests and/or lacked current documentation for repair or overhaul of components. Discrepancies include:
(1) Failure to perform required manufacturer’s test procedures prior to returning an article to service;
(2) Lack of test equipment to perform required tests;
(3) Use of inactive, outdated, or superseded technical data to perform component repair and overhaul; and
(4) Use of special or test apparatus not calibrated as required by regulations.
Several P/Ns are enlisted within this SUP document.
