India Aims to Develop Fifth-Generation Fighter Jets with Indigenous Engines, Says Rajnath Singh

The Design Rationale Behind McDonnell Douglas’s Three-Engine DC-10 Regulatory and Technical Constraints The decision by McDonnell Douglas to equip the DC-10 with three engines rather than the more straightforward two-engine configuration prevalent today was shaped by a complex set of factors rooted in the technological and regulatory landscape of the late 1960s and 1970s. Central to this choice was the Federal Aviation Administration’s (FAA) “60-minute rule,” which prohibited twin-engine aircraft from flying more than 60 minutes away from a suitable diversion airport. This regulation effectively excluded two-engine widebody jets from operating on long overwater or remote transcontinental routes, thereby limiting their use on many profitable international services. Although jet engine reliability was steadily improving during this period, it had not yet reached a level that inspired full confidence among airlines or regulators for long-haul flights relying on only two engines. By adopting a three-engine, or trijet, design with the third engine mounted in the tail, McDonnell Douglas ensured the DC-10 could circumvent these regulatory restrictions. This configuration granted airlines immediate access to global routes without awaiting regulatory changes or exemptions. Additionally, the extra engine provided vital thrust for operations at high-altitude airports such as Denver and Mexico City, where thinner air posed significant performance challenges. Market Demands and Competitive Pressures In the 1970s, airlines demanded aircraft that combined safety, versatility, and operational flexibility. The DC-10’s trijet design addressed these needs by offering enhanced safety margins and route flexibility, which were critical competitive advantages in a rapidly evolving market. McDonnell Douglas did explore the possibility of a two-engine variant, the “DC-10 Twin,” which promised reduced weight and improved fuel efficiency akin to the emerging Airbus A300. However, the prevailing regulatory constraints that limited twinjets’ operational range rendered this option commercially unfeasible for long-haul flights, leading the company to abandon the concept. Safety Concerns and Shifting Market Perceptions Despite its initial advantages, the DC-10’s three-engine layout became a subject of controversy following several high-profile accidents in the 1970s, which raised questions about the aircraft’s safety and affected public confidence. Concurrently, advances in engine reliability and evolving regulatory standards began to alter market perceptions. Competitors responded accordingly; Boeing introduced the two-engine 767, emphasizing the improved reliability and efficiency of twin-engine designs. The aviation industry’s transition into the 1980s was marked by the introduction of ETOPS (Extended-range Twin-Engine Operations Performance Standards), which permitted twinjets to operate on routes previously restricted to trijets and four-engine aircraft. This regulatory shift, combined with growing confidence in twin-engine safety, prompted airlines to favor more economical two-engine aircraft for long-haul operations. The widespread adoption of twinjets ultimately signaled the decline of the trijet era. Legacy The DC-10’s three-engine configuration was a direct response to the unique challenges of its time, balancing regulatory compliance, technical feasibility, and market demands. Although eventually supplanted by more efficient twin-engine aircraft, the rationale behind the DC-10’s design provides valuable insight into a transformative period in aviation history, bridging the era of four-engine jetliners and the modern age of fuel-efficient twinjets.

CFM56 Engine Values Highlight Investor Opportunities and Risks The market for CFM International’s CFM56 engines has witnessed remarkable growth, with values for certain variants increasing by as much as 50% over the past two years. This surge, detailed by Magnetic Leasing in an exclusive report for Aviation Week Network, reveals a complex landscape of lucrative opportunities alongside emerging risks for investors and operators. Market Dynamics and Valuation Challenges Magnetic Leasing, a prominent engine leasing firm, cautions that traditional valuation benchmarks for used engines are becoming less reliable. According to CEO Alex Vella, the uniqueness of each used engine—shaped by factors such as component condition, maintenance history, utilization patterns, and prevailing lease rates—renders broad valuations difficult. The primary market driver remains straightforward: demand continues to outpace supply, particularly for the CFM56-7B variant. Although the CFM56-5B lags slightly in value, it is also experiencing upward momentum, especially among high-thrust models. Rising operational costs are significantly influencing investment strategies. The escalating expenses associated with shop visits—attributable to increased labor, material, and OEM part prices—have made rebuilding CFM56 engines to traditional standards of 7,500 to 9,000 flight cycles increasingly uneconomical. Consequently, many operators are opting for shorter, less costly maintenance cycles targeting 4,000 to 6,000 flight cycles. High build standards are now generally reserved for engines undergoing major performance overhauls, where a target of 10,000 cycles or more is necessary to justify the investment. Industry Responses and Market Outlook This evolving environment has prompted strategic responses across the industry. Hanwha Aviation has secured financing to expand its engine leasing portfolio, focusing primarily on CFM56 engines to capitalize on current demand. Ryanair plans to conduct additional engine shop visits by year-end to optimize its fleet’s performance and cost efficiency. Other market participants are adapting accordingly: APOC Aviation is revising its strategies to address regional demand fluctuations and persistent supply constraints, while FTAI Aviation is enhancing its repair capabilities to reduce dependence on third-party services. Compounding these challenges is a sharp rise in OEM material prices, which have increased by approximately 30% over two years, alongside a shortage of used serviceable material. This scarcity compels many operators to purchase new parts, thereby increasing investment requirements and compressing profit margins. Magnetic Leasing anticipates a market correction within the next two to three years. Smaller carriers, still financially vulnerable following the pandemic, face heightened risk. Should lease rates become unsustainable, a wave of airline failures could result in increased returns of airframes, some of which may not be economically viable to convert. This scenario could lead to more engine teardowns and a renewed supply of green-time material, potentially alleviating current supply constraints. Amid this volatility, specialist maintenance, repair, and overhaul providers such as Aero Norway are consolidating their focus, concentrating almost exclusively on CFM56-5B and -7B engines to streamline operations and prepare for future transitions. CEO Neil Russell notes that insights gained from the CFM56 market are informing the company’s move into Leap-1A and -1B engine work. Aero Norway is also employing artificial intelligence to enhance material planning and operational forecasting, aiming to deliver greater value and reduce complexity for airline customers. With valuations reaching record highs on one hand and mounting operational pressures on the other, the CFM56 engine market stands at a critical crossroads, presenting both significant opportunities and considerable risks for investors and operators alike.
