EASA Plans Proposal for Non-OEM Parts Design and Manufacture

Provision of replacement engine parts by non-OEM sources account for more than half of a $400 million annual business. Before next year, European regulators expect to propose a rule amendment to cover the use of PMA parts.

The European Aviation Safety Agency (EASA) could, by year-end, publish proposals to clarify and simplify approval procedures covering design and production of some non-critical parts by companies other than original equipment manufacturers (OEMs). Such parts manufacture approval (PMA) processes could increase competition in a market that provides North American carriers access to thousands of less-expensive replacement parts.

The EASA is considering a better balance between U.S. PMA procedures and European regulation of replacement-parts design and manufacture, comparing methods, acceptable means of compliance (AMC) and any need for rule changes. Non-OEM provision of engine parts accounts for more than 50 percent of the $400 million/year PMA business, according to aerospace consultancy AeroStrategy.
