A Parts Manufacturer Approval (PMA) is a certification issued by the FAA that allows a manufacturer to produce a replacement part such as Pressure Switch for an aircraft they did not initially manufacture. Before a component is granted a PMA, the manufacturer must prove by comparative or general analysis that the new part meets the functional requirements of the currently installed part. When repairing or upgrading aircraft, it is crucial to use PMA certified parts so that you and your maintenance team are assured that the product is safe and compatible with the plane in question. Fasteners 360 is a premier distributor of PMA parts such as 21SN04-426-Pressure Switch, always offering customers industry-leading shipping times. In addition to the peace of mind that comes with acquiring a PMA part, countless items that we distribute undergo visual inspection and cross-verification to ensure you receive the highest quality parts.
