Like all of our PMA sealants, NSL890RC B4 is a cost-saving alternative product that can be safely used in place of the original part. That’s because PMA manufacturers like us submit to a rigorous review process with the FAA in order to ensure that our parts are airworthy. With that approval, you can know that this PMA part will function the same or better than the OEM part. Find out more about PMA parts with our Introductory Guide to PMA Sealants.
