Suspected Unapproved Parts Details
During a FAA Suspected Unapproved Parts (SUP) investigation it was determined that National Precision Bearing, a division of Mechatronics, Inc. and a distributor for Schatz Bearing Corporation, sold Boeing designed bearings manufactured by Schatz Bearing Corporation as suitable for installation on a type certificated products without FAA manufacturer approval. Schatz Bearing and National Precision Bearing have been identified by Boeing as approved sources for Boeing to purchase bearings. This approval is through Boeing’s internal supplier control procedures under Production Certificate (PC) 700, but does not extend beyond Boeing, Boeing subcontractors and suppliers for subsequent sale to Boeing. These bearings were advertised for sale and sold by National Precision Bearing to the aviation public.
