Secretary delays global wing organizational structure Published July 10, 2008 WASHINGTON (AFPN) -- Acting Secretary of the Air Force Michael Donley directed the delay of the global wing organizational structure implementation July 2. The global wing structure is designed to realign fighter, bomber and rescue aircraft maintenance units into flying squadrons. The initiative would also rename all maintenance groups as materiel groups composed of logistics readiness squadrons, aerial port squadrons, maintenance squadrons and other maintenance functions not transferring with the AMUs. Units across the Air Force had been directed to implement these changes between July 1 and Nov. 30. Secretary Donley directed the delay in order to have an opportunity to discuss the appropriateness and timeliness of these changes with Air Force senior leaders. A final implementation decision will not be made until after the secretary has conducted these discussions.
