The Grumman-Gang is a vibrant community of airplane owners and pilots dedicated to the iconic Grumman light aircraft. Founded by Mark Matthews in Independence, Oregon, this dynamic group fosters communication among approximately 1,000 active members through an email mailing list. Participants share valuable insights on aircraft maintenance, sourcing parts, and coordinating fly-ins, creating a rich tapestry of knowledge and camaraderie. The mailing list delivers 20 to 30 messages daily, with an option for members to receive a digest version for convenience.

Although the Grumman-Gang operates with a level of organizational structure, it embodies a spirit of technological anarchy where enthusiasts freely exchange opinions and advice. Members, including a diverse roster of aviation aficionados, are encouraged to engage in discussions and share experiences, all while adhering to a set of guidelines. The passion for flying and the support network established by the Grumman-Gang highlight the joy and adventure of being part of the Grumman aircraft community.
