What's New!
Recently, there were revisions made to the PERP Regulation and Portable Engine ATCM. These revisions became effective on February 19, 2011, and all holders of PERP Registrations are now subject to the new requirements. Updated operating conditions reflecting the new requirements will be issued upon renewal for all existing registrations. A flyer (PDF) containing a summary of the changes was mailed to all holders of PERP registration. En Espanol Aqui (PDF).
