Aviation and aircraft maintenance, repair and overhaul (MRO) is a critical market. Its purpose is to ensures the safety and airworthiness of aircraft or aircraft components in line with stringent regulations.

What is an aviation MRO?

In aviation, MRO refers to a set of procedural activities, including administration, supervision and managerial practices aimed at restoring aircraft to its safe and original state, performance and function. 

MRO companies, which retain spacious facilities to accommodate aircraft, provide essential services, including scheduled maintenance activities of certain segments such as the engine, line, airframe or component of an aircraft.

A wide variety of MRO companies concentrate on only one segment. For example, some enterprises focus exclusively on engine or airframe MRO services.

Furthermore, to ensure compliance with the aviation industry’s strict regulations, the MRO sector and its companies must be certified by the aviation regulatory bodies such as the United States Federal Aviation Administration (FAA) or European Union Aviation Safety Agency (EASA) to name a few.

Here, AeroTime explores the leading companies in the aviation MRO market.

Leading players in aviation MRO market

GE Aviation

GE Aviation was founded in 1917 and counts 104 years of operation in the global MRO market. The American MRO giant is headquartered in Evandale, Ohio, the United States. 

GE Aviation, an operating unit of General Electric, is a global provider of jet and turboprop engines, as well as avionics and engine maintenance for commercial, military, business and general aircraft. The company’s products, services and activities are subject to a number of regulators such as the U.S. Federal Aviation Administration (FAA), the European Aviation Safety Agency (EASA), and other regulatory bodies. 

With more than 33,000 engines in service, GE is a world leader in jet engine manufacturing. The company’s key customers include Boeing, Airbus, Bombardier, Embraer, Sikorsky, and Lockeed Martin. The MRO giant also boasts a network of nearly 80 plants in 19 countries, which manufacture engines and provide overhaul, maintenance and repair services. 

Interestingly, GE Aviation is best-known for developing the world’s largest and most powerful commercial engine. In the early 1990s, GE developed the GE90 turbofan engine to power the twin-engine Boeing 777. The baseline GE90 engine was certified on the aircraft in 1995 and became the first commercial jet engine to operate with carbon-fiber composite front fan blades.

In 2013, and building upon the GE90 success, GE launched the GE9X engine as the sole engine for the yet to be certified Boeing 777X aircraft. Then, in 2019, GE has announced that the GE9X was the most powerful commercial jet engine after reaching 134,300 pounds of thrust during ground testing in Peebles, Ohio. This broke the previous record held by the GE90-115B engine, which was 127,900 pounds in 2002. By 2020, the GE9X had more than 700 engines on order for the Boeing 777X.

Recently, GE Aviation and Safran, a leading international high-technology group, launched the CFM RISE program to develop a new generation of sustainable engines.

John Slattery, President and CEO of GE Aviation was quoted in the company’s press release as saying:  “Together, through the RISE technology demonstration program, we are reinventing the future of flight, bringing an advanced suite of revolutionary technologies to market that will take the next generation of single-aisle aircraft to a new level of fuel efficiency and reduced emissions.”

According to Slattery, the new engine is intended for narrow-body aircraft, thus replacing the CFM LEAP currently in use by the latest generation of mainline jets, such as Boeing 737 MAX, Airbus A320neo and COMAC C919.

CFM International, a 50/50 joint venture of American GE Aviation and French Safran, was founded in the mid-70s. Since then, it has become one of the world's most prolific manufacturers of aviation engines for narrow-body aircraft.

MRO market trends: what’s the latest?

Over the last decade, the commercial MRO market has experienced steady growth owing to the global economic rise, an increase in demand for air travel and expanding global fleet. However, the COVID-19 pandemic provided a setback during the last 12 months or so.

According to the International Air Transport Association (IATA), the global aviation industry lost over $118 billion in 2020 and dozens of airlines seek bankruptcy protection or stop flying entirely as a result. During the crisis, cash preservation and cost control remained a priority for airlines, which also resulted in bad news for aerospace manufacturers and maintenance, repair, and overhaul (MRO) service providers.

In total, the COVID-19 crisis is estimated to have lowered spending on commercial MRO by about $40 billion in 2020, according to analysis conducted by the American consulting firm Oliver Wyman, Global Fleet and MRO Market Forecast 2021-2031. As per Oliver Wyman estimates, the spending on commercial MRO in 2021 will reach $68 billion.

Due to the ongoing pandemic, commercial MRO demand is unlikely to return to pre-pandemic levels until the end of 2022, according to the Global Fleet and MRO Market Forecast 2021-2031 study. The timing of MRO’s return to pre-pandemic levels of spend is primarily determined by a recovery in air travel demand, which is driven by economic recovery and the pace at which the international community battles the COVID-19 pandemic.

However, despite the reduced expectations for MRO growth, the compound annual growth of the sector between 2019 to 2031 is expected to grow by 3%, according to the analysis.
