KC-135s and C-130Js are the next aircraft to enter the Air Force’s data-driven maintenance program

By:

The KC-135 refueling tanker and the C-130J airlifter will be the next two aircraft to be part of the Air Force's predictive maintenance program, part of the service's effort to do maintenance before airplanes break--and improve mission capable and availability rates, according to Air Mobility Command's logistics director.

"The bottom line is to get to where we are scheduling all of our maintenance, rather than reacting to the maintenance,' said Brig. Gen. Steven Blaymaier, who oversees Air Mobility Command's logistics, engineering and force protection, in an interview at the 2018 Airlift Tanker Association symposium outside Dallas, Texas. “We want our units to achieve their mission-capable rates on a sustained basis.”

According to the latest available data, from FY2017, the KC-135 fleet had, on average, a 74 percent mission capable rate, and the C-130J fleet had a 77 percent mission capable rate. As for the rest of the mobility fleet, by that same data, the C-5M fleet stood at 60 percent, the C-130H fleet was at 73 percent, and the C-17 fleet was at 84 percent mission capable.

The concept, known as conditions based maintenance, has already been rolled out to the C-5 fleet within AMC, and the B-1 fleet in Air Force Global Strike Command. It uses algorithms based on reams of data to create models to predict when a part might break, rather than waiting for it to fail. Its a standard practice in the commercial aviation industry, and is now making its way into the Air Force.

Blaymaier says the KC-135 fleet will join the program in spring of 2019, and the C-130J fleet will follow in the summer. Blaymaier also added that the other aircraft in AMC's fleet would be joining the program eventually, like the C-17 and KC-10.

“They're all in work at their program offices right now,” he said. “What we learn from C-5 will be incorporated into the other aircraft.”

Blaymaier also said the Air Force was modelling their effort after Delta Airlines's Tech Ops division's procedures, and that the service was at the beginning or “crawl stage” of the process. He also noted that Delta took “eight years” to get achieve the results they were looking for, and that the Air Force was working on that path.

In September, Lt. Gen. Robert McMurray, commander of the Air Force Sustainment Center, told Defense News that the conditions-based maintenance program was critical to increasing the readiness of the Air Force's aircraft.

"Given the aging fleet situation that we have, we probably need to be using data better to take care of it — which is a drive toward what most everyone right now is saying is the right way to manage fleet sustainment, which is through condition-based maintenance and data analytics,” he said at the time.

Another benefit Blaymaier described was that the service will be able to track maintenance needs by individual aircraft, rather than by a general fleet-wide standard. That could reduce time in depots and increase mission capable rates, a top priority of senior Pentagon leaders.

“As we move forward with conditions based maintenance plus (CBM+) and predictive analytics, we'll be able to know by tail number which parts are going to fail on certain aircraft," he said."It'll be much more surgical [and] operational."

Blaymaier added that while the transition to conditions based maintenance might be a long journey, it would lead to huge benefits for the Air Force.

“Ultimately we want to achieve those aircraft availability standards that we established for each of our fleets that are required to meet our wartime taskings,” he said.

  • Boeing Defense to Surpass Commercial Side For First Time In More Than a Decade

    Boeing Defense to Surpass Commercial Side For First Time In More Than a Decade

    But that's no cakewalk as new Air Force One and KC-46 tanker eat into the company's cash. Updated, April 30, 2020, with a U.S. Air Force statement. For the first time in 12 years, Boeing executives expect the company's defense and space unit to outperform its commercial airplane business, which is reeling from coronavirus and 737 Max losses. Boeing's defense business has not outperformed its commercial side since 2008, when the commercial market was still recovering from post-9/11 declines and U.S. defense spending spiked during the wars in Iraq and Afghanistan. The prediction comes on the back of pre-existing problems in the Boeing Defense, Space & Security division. The company's defense unit took a $1 billion hit in the first quarter of 2020, adding to the growing list of financial woes for the company trying to dig itself out of a massive hole. “This year ... the defense business will probably be bigger than the commercial business,” Boeing CEO David Calhoun said during a call with Wall Street analysts. “That will probably hold for a while.” MOST READ 1Artificial Intelligence Outperforms Human Intel Analysts In a Key Area 2Pentagon's ‘Willingness to Kiss the President's Ass' Worries Top Lawmaker 3Boeing Defense to Surpass Commercial Side For First Time In More Than a Decade SUBSCRIBE Receive daily email updates: Subscribe to the Defense One daily. Be the first to receive updates. ADVERTISEMENT Additionally, executives said Wednesday that Boeing would lose $827 million on its work building KC-46 aerial refueling tankers and $168 million on the new Air Force One 747s that will fly the president, according to executives and regulatory filings. It's the latest black eye for the tanker project, which has cost the planemaker more than $4 billion over the past nine years. However, it is the first cost increase on the high-profile Air Force One project, which President Donald Trump personally negotiated with former Boeing CEO Dennis Muilenburg. Boeing began work converting two 747 jetliners into the unique Air Force One configuration in January before the coronavirus pandemic forced many workers out of the office. “As we've had folks working virtually, and particularly on the engineering side — as well as that's gone — it's certainly experienced some inefficiencies that has caused us to reevaluate our estimate to complete those efforts,” Boeing CFO Greg Smith, said of the Air Force One project during a Wednesday afternoon call with reporters. “The team has been doing a great job managing the program and executing very well on many fronts, but this we could not offset in the quarter as a result of COVID,” he said. “The program remains on schedule and ... continuing to execute, but we're looking for opportunities obviously to mitigate any further risk that we may have as a result of COVID.” The terms of the Air Force One contract require Boeing, not taxpayers, to pay for any cost increases during the development of the plane, which the military calls a VC-25B. Despite the coronavirus-related issues, Ann Stefanek, an Air Force spokeswoman, said the project remains on track. “As planned in the baseline schedule, the next phase of modification is on course to begin in June 2020,” Stefanek said in an emailed statement. “To maintain current schedule, Boeing and the VC-25B program office adopted maximum use of virtual tools, most notably to close Critical Design Review in March 2020 and conduct a modification readiness review in April 2020.” As for the tanker, $551 million in cost increases stem from a deal reached between the Air Force and Boeing requiring the company to fix the complicated camera system used when refueling other aircraft. Most of the remaining $276 million is the result of coronavirus-related factory closures in Washington state where the tanker is built, and a “cost shift” resulting from slowing production of other commercial manufacturing. “I do believe that that program now is exactly where it needs to be,” Calhoun said of the KC-46. “We're going to finish well. Importantly our customer is going to feel like we have finished well and we've delivered a product that is second to none. I do believe that even the tanker future is significantly brighter than the one we've experienced up until now.” Calhoun also touted the company's development work. Although he did not mention any projects by name, Boeing is in the early stages of testing two new aircraft — the T-7A pilot training jet and MQ-25 refueling drone. “Our development programs at the early stages are all looking quite good. We're really not off plan on anything and usually by now we have a snip that we might be. I feel pretty good about the risk profile of our defense business despite the difficulties that we've attempted to overcome in just the last couple of years.” The same can't be said of the company's commercial airliner and aircraft repair businesses. Boeing is planning to cut 10 percent of its 160,000 employees through voluntary layoffs, attrition and involuntary layoffs. The coronavirus has driven a substantial blow to the storied 104-year-old aerospace and defense company, which had already been reeling from the fallout of deadly 737 Max crashes in October 2018 and March 2019. Passenger air travel has fallen to record lows prompting airlines to cancel flights, ground aircraft, and defer buying new planes. Boeing in late March temporarily stopped making commercial and military aircraft — including the tanker and the Navy's P-8 submarine hunter — in the Seattle-area, a COVID-19 hotbed. It also shut down its military assembly lines in Philadelphia for the Chinook and MH-139 Grey Wolf helicopters, and the tilt-rotor Osprey. Those factories have since reopened. A shuttered 787 Dreamliner factory in Charleston, South Carolina, is expected to reopen next week. Now all eyes — including at the Pentagon — are watching to see how Boeing manages tens of thousands of employees on its complex assembly lines with new social distancing procedures in place. If successful, the model could become a blueprint for other U.S. manufacturers. “They have allowed me to share their practices more broadly with industry to make sure that anything that is working for them to either be safer or get back to work, that that's something that can be shared with all,” Will Roper, head of Air Force acquisition, said Wednesday. Boeing began the year with hopes of fixing its troubled 737 Max and restoring public confidence in the world's largest planemaker. Unable to deliver the unflyable Max to the airlines, it stopped building them in early January as it began running out of places to park them. Photos showed planes carefully aligned next to one another on tarmacs and even in employee parking lots. There's still no formal timetable for getting the Max flying again, although executives are hopeful regulators will approve a number of fixes in the coming months and that it can begin delivering 737 Max aircraft to airlines in the third quarter. https://www.defenseone.com/business/2020/04/boeing-defense-surpass-commercial-side-first-time-more-decade/165020/

  • Le Brexit déjà en marche dans la politique européenne de défense

    Le Brexit déjà en marche dans la politique européenne de défense

    (B2 – exclusif) Peu importe les émois à Westminster et les tourments de Downing Street, ou la conduite sans ceinture du Prince Philippe, dans le domaine des opérations de stabilisation menées par l'Union européenne (au titre de la PSDC), le départ des Britanniques est désormais bien engagé et devrait se terminer bientôt Un mouvement engagé Le transfert du QG de l'opération anti-piraterie Première concernée, la plus emblématique, l'opération anti-piraterie de l'UE (alias EUNAVFOR Atalanta) va déménager de Northwood (près de Londres) à la Rota et à Brest, le commandant britannique cédant sa place au commandant espagnol avec un second français. Le QG de La Rota est en pleine préparation, le QG secondaire de Brest — qui accueille la liaison avec la marine marchande — également. Les officiers ont commencé à rejoindre leur poste. Le « tuilage » est en cours, selon nos informations (lire : La revanche de Trafalgar). Le changement de commandement en Bosnie-Herzégovine Deuxième concernée, l'opération EUFOR Althea en Bosnie-Herzégovine. Plus discrète, après avoir été l'opération phare (de l'OTAN sous le nom IFOR) et de l'Union européenne, elle ne rassemble plus aujourd'hui que 600 hommes maximum. Elle n'en est pas moins importante, car un « poste d'observation » important de ce qui se passe dans les Balkans, notamment en matière de retour des combattants étrangers. Un Français va prendre la tête de l'opération, à partir du QG de l'OTAN à Mons (le SHAPE). Un petit noyau de Français est aussi prévu à Sarajevo au sein de l'état-major de la force (lire : Le retour de la France dans l'opération de l'UE en Bosnie-Herzégovine). L'abandon d'un poste de numéro 2 en Somalie Enfin, au sein de la mission civile EUCAP Somalia chargée d'assurer le conseil et la formation des Somaliens pour la sécurité maritime, le poste de numéro 2 assuré par un Britannique est en voie de changer de main, selon nos informations. Les Britanniques ne pouvant assurer de poste de commandement des opérations européennes. Le retrait du planning des battlegroups De même, en matière de force de réaction rapide de l'UE, les Britanniques se sont retirés du tour d'astreinte des battlegroups (lire : La prise d'astreinte française au battlegroup 2019 se prépare). Du personnel détaché au titre d'un pays tiers Des Britanniques resteront dans quelques unes de ces missions et opérations qu'ils estiment ‘stratégiques', en particulier celles déployées en Somalie et dans l'Océan indien. Mais en tant que pays tiers, dès que le Brexit sera consommé. Un officier britannique de la marine marchande devrait ainsi être positionné à Brest, chargé d'assurer le lien (précieux) avec toutes les structures britanniques de la marine marchande. Et dans la mission EUCAP Somalia, Londres entend détacher un de ses officiers pour occuper le poste de chef des opérations. Une transition en douceur Dans toutes ces opérations et missions, le départ des Britanniques est désormais non seulement acté, mais leur remplacement est assuré, sans difficulté. Il est difficile désormais, voire quasi impossible, de faire machine arrière. Les Britanniques ont perdu leur tour. Difficile de faire machine arrière Si le Brexit devait être repoussé, il ne changera pas les changements opérés dans les commandements : la relève est déjà en place. Les Britanniques qui occupaient ces positions ont déjà (ou vont) retrouver d'autres fonctions dans l'armée britannique, l'OTAN ou d'autres opérations multinationales. Et dans les générations de force actuelles, ce serait un pari insensé pour les planificateurs britanniques de miser sur une possible annulation ou prolongation longue du Brexit pour faire de nouvelles offres de participation importante. Quelques leçons du départ A cette transition en douceur, si en douceur qu'elle passe inaperçue, on peut tirer d'ores-et-déjà quelques leçons. Premièrement, contrairement à ce qu'avaient affirmé certains dignitaires britanniques, assis confortablement dans leurs sièges en cuir dans des ministères londoniens, et quelques observateurs, peu au fait du fonctionnement réel de l'Union européenne, l'apport britannique dans les missions et opérations de l'Europe de la défense reste modeste. Il peut être facilement compensé, avec juste un peu de bonne volonté de quelques pays membres. Deuxièmement, le départ britannique consacre en fait le retour français dans des opérations et missions qu'ils avaient, ces dernières années, un peu délaissées. Au final, il reste tout de même un pincement au cœur. Les officiers de sa Royale Majesté, croisés durant ces années, m'ont toujours fait bonne impression, avec ce mélange de courtoisie, de rudesse, d'ironie et d'enthousiasme qui fait le charme et l'efficacité de l'armée outre-Manche. Dommage... (Nicolas Gros-Verheyde) https://www.bruxelles2.eu/2019/01/28/le-brexit-deja-en-marche-pour-la-defense/

    US Army test-fires Belgian-made gun amid plans for Stryker upgrade competition

    Pierre Tran PARIS ― The U.S. Army's test-firing of a 30mm gun turret from CMI Defence is seen by the Belgian firm as putting it in a privileged position for an upcoming tender for greater firepower for the Stryker combat vehicle, a company spokesman said. “We're in pole position, “ Xavier Rigo, communications manager of CMI Defence, told Defense News on June 18. “That does not mean we will win the race, but it puts us in a very good position. We are very proud to have been selected for tests, a real recognition for our team and our equipment.” That test-firing stems from a cooperative research and development agreement CMI signed in 2015 with the U.S. Army Armament Research, Development and Engineering Center, which is seeking a lethality upgrade for the Stryker. CMI adapted the turret to fit the U.S. requirement for linkless ammunition, he said. ATK supplies the 30mm gun, which CMI fitted to its turret. The Belgian company also supplies a 105mm gun turret for a bid led by SAIC in the U.S. tender for the Mobile Protected Firepower program. CMI has fielded its Cockerill 3105 turret, which uses its turret and 105mm cannon, with the latter built in a factory in northern France. A Cockerill 3105 turret was among the products on display at the CMI stand at the Eurosatory trade show, which ran June 11-15. The stand at the show two years ago used the Cockerill brand name. BAE Systems, General Dynamics Land Systems and SAIC are the competitors in that Mobile Protected Firepower competition, Rigo said. The next step is a down-select to two bidders, which will be asked to build and supply 12 prototype vehicles for tests. In Europe, CMI is ”in discussion with the Belgian government“ in its search for a role in Belgium's planned €1 billion (U.S. $1.2 billion) acquisition of the Griffon and Jaguar armored vehicles from the French Army Scorpion program. Those talks are exploring the possibility for CMI to participate in local production and maintenance of the Scorpion vehicles, he said. The Belgian project, dubbed Capacité Mobilisé, or CAMO, sparked debate, as the planned acquisition boosted French contractors Arquus, Nexter and Thales, but left CMI turrets by the wayside. CMI has delivered 130 gun turrets and is building some 20 turrets per month to supply GDLS, which has a contract with a Middle Eastern country, he said, declining to identify the client nation. Those turrets are based on four modules, armed with 30mm, 90 mm, 105 mm, and both 105mm and 30mm guns. There are both manned and unmanned versions of the turret. Canadian broadcaster CBC reported March 19 that GLDS Canada has sold to Saudi Arabia combat vehicles armed with 105mm and 30mm guns for ”heavy assault,” anti-tank and direct-fire support. CMI conducted a firing demonstration of its six Cockerill gun turrets June 15 at the French Army Suippes firing range, eastern France. Some 60 representatives of foreign army delegations attended, the company said in a statement. The Belgian company had been one of the bidders for Arquus, the then-Governmental Sales unit of Volvo Group, until the Swedish truck maker canceled the sale. Nexter had been the other bidder. https://www.defensenews.com/digital-show-dailies/eurosatory/2018/06/19/us-army-test-fires-belgian-made-gun-amid-plans-for-stryker-upgrade-competition/
