Critical Parts for Airplane Propellers

The Federal Aviation Administration (FAA) proposes to amend the airworthiness standards for airplane propellers. This action would define what a propeller critical part is, require the identification of propeller critical parts by the manufacturer, and establish engineering, manufacture, and maintenance processes for those parts. The intended effect of this proposal is to ensure the continued airworthiness of propeller critical parts by requiring a system of processes to identify and manage these parts throughout their service life. Adopting this proposal would eliminate regulatory differences between part 35 and European Aviation Safety Agency (EASA) propeller critical parts requirements, thereby simplifying airworthiness approvals for exports.
