Item 4/5:

. Owner/Operator Produced Part. Parts that were produced by an owner/operator for
installation on their own aircraft (i.e., by a certificated air carrier). An owner/operator is

or quality of the part. Participating in the design of the part can include supervising the
manufacture of the part or providing the manufacturer with the following: the design data, the
materials with which to make the part, the fabrication processes, assembly methods, or the
