Maintainers from the 15th Maintenance Group and members from the 36th Squadron, Royal Australian Air Force Base Amberley, perform maintenance on a C-17 Globemaster III at Joint Base Pearl Harbor-Hickam, Hawaii, July 12, 2017. The recently implemented C-17 Aircraft Repair and Maintenance Services Implementing Arrangement enables U.S. and Australian C-17 maintainers to perform full, interoperable cross-maintenance on U.S. or Australian C-17s at mission critical times on a global scale, improving aircraft availability and decreasing aircraft maintenance downtime and maintenance recovery expenses.
