Industry Summary
The 1,042 aircraft engine and parts manufacturers in the US produce civilian and military aircraft engines, engine parts and accessories, other aircraft parts and subassemblies, and auxiliary equipment for aircraft. They may also provide design and development services for new engines and parts, as well as support and repair services for existing products.
Government Regulations and Policies
The aircraft industry is highly regulated by the Federal Aviation Administration in the United States, and equivalent regulatory agencies in other countries.
Availability of Raw Materials
Many expensive and sometimes rare specialty metals are used in the manufacture of aircraft engines and parts.
Recent Developments
May 27, 2025 - Aircraft Makers Struggle to Meet Orders
- Airlines experienced strong demand for flights headed into the 2025 summer travel season, but that good news is also shining a light on the shortage of available commercial jets due to production delays at the world’s largest airplane manufacturers - Boeing and Airbus. Both companies have fallen short of their deadlines for delivery of new aircraft to customers, resulting in industry-wide capacity boosts of only 1-3% for the summer season, according to EasyJet CEO Kenton Jarvis. Europe’s Airbus delivered 56 jets in April 2025, an 8% drop year over year. Boeing, which has been consumed with safety crises and production problems for several years, is slowly improving this year and delivered 45 jets in April, which doubled from March. However, airplane delivery totals for both companies in Q1 indicate they will have trouble meeting their targets for the year, per aviation analytics firm Cirium.
- New orders for nondefense aircraft and parts plunged 58.3% in November 2024 year over year - per the US Census Bureau - due to a late 2024 strike by Boeing factory workers. The work stoppage halted production of the company’s 737 MAX airliner, as well as on wide-body 767s and 777s. Along with safety concerns after a string of high-profile in-flight aircraft mishaps, issues at Boeing cascaded down into the aircraft parts industry as a whole with shrinking commercial airliner demand in late 2024. (New commercial aircraft and parts orders had a short-lived rebound of 16.4% in October.) The aircraft giant will lose $150 million in profits in Q1 2025 as a result. On top of all that, Boeing is concerned that any Trump administration tariffs will hamper parts availability from its suppliers and increase its costs at a tenuous time. For now the company says it has sufficient inventory.
- US manufacturing activity contracted in December 2024, marking the ninth consecutive month of contraction for the Manufacturing PMI, according to the Institute for Supply Management’s Manufacturing ISM Report on Business. The Manufacturing PMI registered 49.5% in December, up 0.9 percentage points from the 48.4% recorded in November. A reading above 50% indicates manufacturing expansion. Transportation equipment was one of the seven industries that reported contraction in December, along with Textile Mills; Fabricated Metal Products; Printing & Related Support Activities; Machinery; Chemical Products; and Nonmetallic Mineral Products. Seven manufacturing industries reported growth in December, including Primary Metals; Electrical Equipment, Appliances & Components; Wood Products; Furniture & Related Products; Paper Products; Miscellaneous Manufacturing; and Plastics & Rubber Products.
- According to BNN Bloomberg, GE Aerospace CEO Larry Culp said the company is working with more than a dozen suppliers to resolve disruptions that have slowed the delivery of its jet engines and created delays for planemakers and airlines. Per Culp, “The shortages that cause us to be late on deliveries really come from about 15 different suppliers across our supply chain. We have 550 engineers going in to work with those suppliers to identify bottlenecks, identify constraints and really solve those problems.” He would not elaborate on the amount of time it would take to fix the problems with its suppliers. Culp noted that the company is also focused on ensuring there are no counterfeit parts in the supply chain, noting the issue is a “high priority.”

Industry Structure
Industry size & Structure
The average aircraft engine and parts manufacturer employs 179 workers and generates $59 million in annual revenue.
- The industry includes about 1,042 firms, generating about $61.5 billion in annual sales and employing 186,000 workers.
- The aircraft engine and parts industry is a high technology-driven manufacturing business, characterized by a few large engine and aircraft manufacturers working in close collaboration with many smaller, highly specialized engine subassembly and parts manufacturers.
- About 79% of the industry's establishments have 100 or fewer employees, yet the largest manufacturers employ over 80% of the total industry workforce.
- The largest engine manufacturers, in order of worldwide market share, are GE Aviation, Rolls-Royce, and Pratt-Whitney.
- Most engine and aircraft parts manufacturers sell to civilian, commercial and defense aircraft manufacturers, but usually the end-user customer, such as a commercial airline, dictates which competitive engine and subsystems will be installed in their aircraft.
- Large commercial aircraft manufacturing customers include Boeing, Airbus, Bombardier, and Embraer. The largest general aviation manufacturing customers are Cessna, Cirrus Aircraft, Diamond Aircraft, Mooney, and Piper.
- The largest numbers of industry-related manufacturers are in California, Connecticut, Florida, Texas, Ohio, Michigan, and Arizona.
