Twenty years after the Pentagon issued its first memo on the way forward for predictive upkeep, the highest federal watchdog says the army nonetheless hasn’t totally reaped its advantages.
A Dec. 8 Authorities Accountability Workplace report argues that lackluster oversight, a dearth of concrete aims and little buy-in amongst rank-and-file maintainers are preserving the Protection Division from saving time and money — and even lives — annually.
“Whereas the army companies have begun piloting predictive upkeep packages on some weapon methods, they don’t substitute components or elements usually primarily based on predictive upkeep forecasts,” GAO mentioned. “By creating plans to implement predictive upkeep, together with motion plans and milestones for weapon methods, the army companies could be higher positioned to find out the place, when and the right way to successfully undertake [it].”
Predictive upkeep has garnered extra consideration previously few years as the concept of machine-learning algorithms and “massive knowledge” acquire traction.
GAO listed greater than 4 dozen floor fight and assist methods, ships and fixed- and rotary-wing plane which might be suitable with predictive upkeep applied sciences — however not all have gotten on board.
The companies are outfitting some property with sensors to gather knowledge that might alert maintainers when a component is sporting out, and the way it would possibly fail. Some methods have relied on that monitoring for many years, just like the Navy’s CH-53 Sea Stallion, whereas others are nonetheless at the hours of darkness.
Pilot packages nonetheless proceed to spring up throughout the Protection Division, referred to as the “Situation-Based mostly Upkeep” and “Situation-Based mostly Upkeep Plus” packages, the Prognostic and Predictive Upkeep effort, and Enhanced Reliability-Centered Upkeep.
Officers estimate these initiatives have saved a whole lot of tens of millions of {dollars}, elevated the provision of fight autos and plane, and reduce time at work.
“For instance, preventive upkeep could require changing a tire each 30,000 miles or 3 years no matter use or situation,” GAO mentioned. “Predictive upkeep could use knowledge from digital sensors mixed with identified historic knowledge to anticipate the optimum time to interchange the tire—not too early as to waste cash, but in addition not too late as to let that tire fail unexpectedly.”
“This method might enable upkeep personnel and automobile customers to carry out upkeep when wanted and make sure that technicians can be found to do the work at the popular location,” the report added.
In essentially the most excessive circumstances, predictive upkeep has helped the Army keep away from 4 pricey or doubtlessly deadly plane crashes.
“Well being monitor sensors on an AH-64 Apache helicopter detected a nostril gearbox malfunction which will have failed inside just a few hours,” GAO mentioned. “The commander [of] Army Aviation and Missile Command mentioned that the early detection previous to failure could have prevented an accident, saved the lives of two personnel, and prevented the lack of the plane.”
Nonetheless, the federal government watchdog famous that the army has been gradual to embrace predictive upkeep as a result of its mechanics are already overworked and typically hesitant to be taught a brand new system. Spare components availability and restricted infrastructure to course of knowledge can pose hurdles as effectively.
“The variety of uniformed upkeep personnel throughout the 4 army companies decreased by about 29,000 from fiscal years 2007 via 2021,” the report added. “This occurred in an period characterised by growing operational calls for, getting older weapon methods in use past their anticipated service life, and the acquisition of newer, more and more advanced weapon methods.”

GAO beneficial 16 steps that might enhance how the army handles predictive upkeep; service officers agreed with a lot of the solutions.
They vary from designating a single entity to handle these efforts for a complete service, to making a schedule with milestones and measurable aims for rolling out proactive upkeep throughout the pressure. As an illustration, a Navy and Marine Corps research of the right way to observe these metrics is slated to finish in fiscal 2024.
The armed forces will likewise forge forward with tweaks to insurance policies which have slowed their progress.
In some circumstances, troops can get waivers that permit them spend the time saved via predictive upkeep on upkeep backlogs elsewhere. Some models are additionally getting the pliability they should order spare components forward of time as a substitute of ready till one thing breaks to start out the method.
“The army companies … acknowledge that shifting to predictive upkeep is a cultural problem that requires sustained management focus,” GAO concluded.
