In addition to designing and manufacturing Harper products, our company takes on the crucial role of certifying these products after their development phase. We have comprehensive testing capabilities and resources that facilitate the certification process for aerospace components, encompassing lifecycle and strength testing. As our production team constructs test articles and fixtures, all of their work is overseen by in-house quality team that works closely with our engineers to ensure conformity. With a track record spanning five decades, Harper has successfully certified thousands of part numbers for flight, including both OEM designs and PMA parts.
