AAP was conceived in 2010 by founder and director Don Roberts upon the recognition that there was no association or organization of professionals who shared the love of aviation and the skills encompassed within the realm of aircraft certification. After years of planning and laying the groundwork for AAP, Don joined with Mike Fox and Denna Mason to officially incorporate AAP as a non-profit corporation in the State of Texas on 30 November 2015. In February of 2016, the U.S. Internal Revenue Service granted AAP tax exempt status.  AAP was introduced at the 2016 Aircraft Airworthiness & Sustainment Conference in March 2016 and was well received. AAP held its first member meeting on 12 April 2016.
