Landmark Aviation is an aviation services company that offers a wide variety of services at MRO repair centers, at 34 FBOs across the United States and Canada, and within its aircraft sales, charter and management business. The company also operates Associated Air Center, a transport completion center. Landmark Aviation is derived from a company called "Garrett/Piedmont Hawthorne/Associated" which operated for about a year before being rebranded in October 2005. Garrett/Piedmont Hawthorne/Associated was in turn created from the merger of three companies (Garrett Aviation, Piedmont Hawthorne, and Associated Air) which were all owned by the Carlyle Group.
