  Impact of COVID-19 on commercial MRO

  Opinion: How COVID-19 Has Already Changed Everything David Marcontell April 17, 2020 Oliver Wyman To say that COVID-19 is having a devastating effect on aviation is an understatement. With hundreds of millions of people living under stay-at-home orders and unemployment rates in the U.S. and Europe rising faster than they ever have, global airline capacity in available seat-miles is down 59% compared to what it was at this time last year. The International Air Transport Association is forecasting airline losses of $252 billion—a tally that has been revised upward twice in the last six weeks. At my own firm, we cut our 2020 forecast for demand in the MRO market by $17-35 billion to reflect the nearly 11,000 aircraft that have been taken out of service and the 50% drop in daily utilization for those that are still flying. Oliver Wyman also lowered its projection for new aircraft deliveries by 50-60% versus 2019 after a comprehensive review of original equipment manufacturer (OEM) build projections versus airline demand. Deliveries for most current-production models are expected to drop 50% or more in 2021 and 2022. As a result, we project that it will be well into 2022 before the global MRO market might return to the size it was before COVID-19. This crisis has gone well past the point of a V-shaped recovery. Lasting damage has been done, and not unlike the Sept. 11, 2001, terrorist attacks or the 2008 global financial crisis, the behavior of governments, businesses and the public is likely to have been changed forever. Following 9/11, it took nearly 18 months for passenger traffic to return to its previous level, and when it finally did, travel looked very different than it had before the attacks. Passenger anxiety and the “hassle” factor associated with heightened airport security caused people to stay at home or drive. It took nearly a decade for the public to adjust to the new normal of commercial air travel. In a post-COVID-19 environment, it is not unrealistic to expect new screening protocols to be put in place to help manage the risk of reinfection or an emergence of new hot spots. Already, international public health officials are considering such tools as immunization passports and body temperature scanning (already in use by some airports) that would be applicable to everyone on every flight, much like our security screening is today. In addition, virtual meeting technology—adoption of which is expanding quickly out of necessity—is now becoming business as usual for work and socializing, and it's unlikely we will turn away from it entirely even when the disease is a memory. These combined influences will undoubtedly slow passenger traffic growth. COVID-19 also will change the industry's labor landscape. For the past several years, the aviation industry has been concerned with a looming labor shortage. Before the coronavirus crisis, regional airlines were already being forced to shut down because they couldn't find enough pilots; others were trimming flight schedules. A stunning 90% of the Aeronautical Repair Station Association's 2019 survey reported difficulty finding enough technicians—a situation that cost ARSA members more than $100 million per month in unrealized revenue. COVID-19 will change all that. With the global fleet expected to have 1,200 fewer airplanes flying in 2021 than 2019, the industry will need roughly 18,000 fewer pilots and 8,400 fewer aviation maintenance technicians in 2021. The depth of the cutbacks is the equivalent of grounding 1-2 years' worth of graduates from training and certification programs around the world. How many would-be pilots and mechanics may now be dissuaded from pursuing a career in aviation with those statistics? If people turn away now, when aviation comes back it may be a few years before that candidate pipeline is restored. Another example of permanent change from aviation's last cataclysmic event was the consolidation of the OEM supply chain after the Great Recession. Tier 1 and Tier 2 suppliers went on a buying spree, gobbling up smaller companies. While the post-COVID-19 business environment will undoubtedly be hazardous for these same suppliers, the consolidation of the past decade has put them in a better position to survive this upheaval. Can the same be said for the MRO community, which comprises many smaller, privately held and family-owned companies? I suspect not. While governments are scrambling to provide financial relief for small businesses hurt by the global economic shutdown, these efforts will likely fall short. The result might well be a further consolidated MRO community dominated by the OEMs plus a handful of fully integrated firms that provide support to both OEMs and airlines. COVID-19 is a painful reminder that aviation always will be a cyclical business. With each cycle, the industry renews itself, performing better than before. One should expect this cycle to be no different. The biggest question is: How long will this cycle last? —David Marcontell, Oliver Wyman partner and general manager of its Cavok division, has aftermarket experience with leading OEMs, airlines, MROs and financial services.

  New policy addresses 3D parts for Army aircraft

  By Courtesy As the Army explores the potential of some advanced manufacturing methods and 3D-printed parts to maintain and sustain its aviation fleet, recently published guidance aims to strike a balance between safety, improvements to readiness and escalating costs. Advanced manufacturing refers to new ways of making existing products and the production of new products using advances in technology. Advanced manufacturing includes additive manufacturing, a process of joining materials to make parts from 3D-model data. Additive manufacturing differs from the traditional subtractive process that cuts away material to shape and produce parts. The U.S. Army Aviation and Missile Command recently published a policy memorandum addressing advanced manufacturing for Army aircraft parts, components and support products. “Evolving technologies create a unique challenge as we determine the airworthiness of parts when the data is immature, incomplete or even non-existent,” said AMCOM Commander Maj. Gen. Todd Royar, who serves as the Army's airworthiness authority, responsible for ensuring the safety of the service's aircraft components. As enduring aircraft, like the UH-60 Black Hawk helicopter, continue in service, the supply system with face challenges with obsolescence, meaning parts that are difficult to acquire or receive no bids from potential vendors to manufacture. As the Army keeps pace with technology, advanced manufacturing creates opportunities to optimize long-term sustainment efforts. The Army established a partnership recently with Wichita State University's National Institute for Aviation Research (NIAR) to create a “digital twin” of an aging Black Hawk model. “One of the primary tasks in this effort is to convert all legacy 2D drawings of this aircraft into modern 3D parametric models,” said John Tomblin, senior Vice-President for Industry and Defense Programs and Executive Director of NIAR at Wichita State University. “This will allow the Army to source parts that are out of production as well as use advanced techniques, such as additive manufacturing, to produce parts.” The digital twin opens a door to the 3D modeling and more opportunities to use parts made through additive manufacturing. The NIAR project is not the Army's only effort. Army Aviation is already using advanced manufacturing methods and 3D-printed parts to solve specific challenges. When several CH-47 helicopters experienced structural cracks at a certain portion of the frame assembly, an initial solution was to replace the entire frame assembly. “Replacing the entire assembly is a time-consuming task that also poses logistical challenges because replacements are difficult to obtain,” said AMCOM's Aviation Branch Maintenance Officer, Chief Warrant Officer 5 Michael Cavaco. Instead, engineers designed a solution to restore the cracked frames to their original strength by creating repair fittings using Computer-Aided Design models. “After five iterations of 3D-printing prototypes, test fit and model adjustments, a final design solution was achieved,” Cavaco said. Additionally, 3D printers have created several tools and shop aids that have benefitted the field. Many of these stand-alone items that support maintenance operations are authorized within Army technical manuals, depot maintenance work requirements or similar publications. While too early to predict overall cost and time savings, the advantages of advanced manufacturing are significant. The use of advanced manufactured parts will eliminate wait time on back-ordered parts that, ultimately, delay repairs. A key focus of AMCOM's AM policy is on inserting evolving technologies into enduring designs that have relied on traditional manufacturing processes throughout their acquisition lifecycle. However, future Aviation are benefiting as well from advanced manufacturing. The Improved Turbine Engine Program (ITEP) includes a number of advanced manufacturing elements. “ITEP benefits from advanced manufacturing include reduced cost, reduced weight, increased durability, and enhanced performance when compared to traditional manufacturing methods,” said Col. Roger Kuykendall, the project manager for Aviation Turbine Engines. “The benefits of AM stem from the unique capability to produce more complex hardware shapes while simultaneously reducing part count.” The fine details of airworthiness expectations asserted in this policy were crafted by a team of engineers at the U.S. Army Combat Capabilities Development Command Aviation and Missile Center, led by Chris Hodges, the current acting associate director for Airworthiness-Technology. Hodges said the new policy was drafted after his team collaborated with stakeholders from across the aviation enterprise, reaching across Army organizations and out to sister services and the Federal Aviation Administration. “We considered a lot of input and ultimately organized expectations and requirements by category, spanning from tools and shop aids to critical safety items,” Hodges said. “The resulting policy sets a solid foundation with room to grow and fill in details as the story evolves.” For Army aviation applications, advanced-manufactured parts and components will be managed under six categories that range from articles that support maintenance operations to those aviation critical safety items, whose failure would result in unacceptable risk. The designated categories prescribe for engineers and manufacturers the allowed materials and appropriate testing methodology for each particular part. The new guidance is not intended as a replacement for other existing policies that address advanced manufacturing. “We intend to be in concert with Army policies and directives that pertain to readiness, maintenance and sustainment,” Royar said. “Our policy provides a deliberate approach to ensure airworthiness and safety while determining where research and efforts may best supplement the supply chain and improve performance while balancing cost.” AMCOM Command Sgt. Major Mike Dove acknowledged the methodology must continue to mature in multiple areas before confidence grows in the ability to measure airworthiness qualification requirements for advanced-manufactured parts. “We fully support the maturation requirements for advanced-manufacturing technology, but not at the expense of flight safety,” Dove said. As Army aviation continues to pursue and include advanced-manufacturing methods, Royar noted the potential impact as the technology evolves. “Advanced manufacturing touches units, depots and the broader supply chain,” Royar said. “As we sustain our enduring aircraft and look to future systems, it is important that we keep pace with this and other emerging technologies for the sake of the warfighter.” https://www.army.mil/article/238868/new_policy_addresses_3d_parts_for_army_aircraft
