The Department of Defense, specifically the Department of the Air Force, is seeking sources for new engine inlet covers tailored to the -135 aircraft fleet, as part of a market research initiative. The 55th Maintenance Group (55 MXG) requires these covers to modernize their -21 equipment maintenance and enhance unit pride during high-visibility events such as airshows and tours. Each cover must feature a tambourine style design with a diameter of 78 inches, include attachment flanges, and come with storage bags, with specific designs for different aircraft variants, including custom insignias and colors. Interested vendors should submit letters of interest and capabilities to Contract Officer SrA Craig Johnson at craig.johnson.37@us.af.mil, as this opportunity may lead to an official solicitation in the future.
