A PMA part is approved for the specific eligibility listed on its FAA record; whether it may go on a particular aircraft, engine or component is the installer's determination from that record and the eligibility list. A part-number match alone does not establish eligibility. Source: FAA DRS PMA database, refreshed weekly. Data, not advice.
