Luke AFB 56th Maintenance Group

The 56th Maintenance Group provides aircraft maintenance on more than 135 F-16s for the Air Force’s only active-duty F-16 training wing. The 56th Maintenance Group flew 13,739 F-16s and 1,965 sorties compiling over 21,280 flying hours, playing a pivotal role in conducting safe and efficient training for 295 new F-16 pilots. As the largest maintenance group in the Air Force, the 56th Maintenance Group consists of more than 2,200 members, operating on an annual budget of $161 million to maintain all assigned F-16s and engine assets, valued at more than $5 billion. The 56th Maintenance Group also directly contributes to Luke’s second mission: training the world’s greatest F-16 crew chiefs. They graduated 313 F-16 crew chiefs in 2015 through the Mission Ready Airmen program that focuses on F-16 maintenance and flightline operations.


The Maintenance Group Staff (MXO) accomplishes many distinctively different yet vital tasks. The group staff consists of Maintenance Operations, Quality Assurance and Weapons Standardization. MXO has an administrative relationship with the Air Force Engineering and Technical Services. Additionally, MXO serves as the group’s liaison to the 372nd Training Squadron, Detachment 12.

The group staff’s mission is managing fleet health and maintenance programs to train the world’s finest maintainers and pilots. They accomplish this through the following key functions: building, executing and analyzing the maintenance and flying schedule; managing and providing training for all group personnel; and managing key group programs and enforcing standards.


The 56th Aircraft Maintenance Squadron provides flightline and intermediate maintenance for 52 Block 20, 25 and 50 F-16C/D aircraft. Manned with 204 U.S. Air Force personnel, 110 Singapore air force personnel and 105 contractors, the squadron’s primary focus is to ensure mission-ready aircraft are maintained to support the training mission for U.S. Air Force active and reserve components, Republic of Singapore air force and Taiwan air force F-16 pilots. To accomplish this task, the squadron is divided into three aircraft maintenance units supporting their associated fighter squadrons. This squadron’s aircraft maintenance units are the 21st Aircraft Maintenance Unit “Gamblers,” the 62nd Aircraft Maintenance Unit “Spikes” and the 425th Aircraft Maintenance Unit “Black Widows.”


The 56th Equipment Maintenance Squadron provides an essential combination of both intermediate and flightline aircraft maintenance capabilities to support six F-16 fighter squadrons. Manned with 450 military and civilian personnel, the squadron is organized into five flights: fabrication, maintenance, armament, munitions and aerospace ground equipment. The men and women of the 56th Equipment Maintenance Squadron are responsible for providing structural maintenance repair, corrosion control, phase inspections, aerospace ground equipment and armament system maintenance support. The squadron is also responsible for providing munitions support to all organizations within the 56th Fighter Wing.


The 56th Component Maintenance Squadron’s primary mission is to perform specialized maintenance on F-16 components, systems and support equipment. This includes inspection, repair and scheduled maintenance of aircraft propulsion, avionics, pneudraulics and electro-environmental, egress and fuel systems for the Air Force’s largest fighter wing. Additionally, the 56th Component Maintenance Squadron repairs and calibrates test, measurement and diagnostic equipment used by more than 190 organizations on Luke Air Force Base and throughout the southwestern United States.

The 56th Component Maintenance Squadron, with a workforce of 285, is organized into four flights: Propulsion; Accessories; Avionics; and Test, Measurement and Diagnostic Equipment.
