Aircraft maintenance is classified into line and base maintenance. Whereas, base maintenance involves major activities and operations that require the aircraft to be taken into the hanger and is put out of service for longer periods.  Line maintenance activities are mostly carried out on the apron area or tarmac during normal turnaround time when passengers are boarding and the aircraft is on the ground (AOG). On the other hand, base maintenance are always scheduled for longer aircraft ground times, in the case of line maintenance may not be scheduled always, it may need to deal with unplanned issues during regular flight operations. In line maintenance, engineers are now equipped with smartphones and smart devices which helps them to understand the maintenance task with ease and mark it done with necessary documents within the specified time.

The market for line maintenance held a major share in the airline market. Line maintenance is a type of maintenance that is performed on every aerodrome and airport rise in airline fleet and increased demand of modern generation aircraft and engines are on of the major factor responsible for market growth. Moreover, taking passenger health safety and comfort into consideration the key players in the market are now providing sanitation solutions due to the ongoing pandemic situation. Thus higher growth numbers are projected during the aircraft line maintenance market forecast period. Developments in the MRO sector have had a vital impact on the market. For Instance,

  • In February 2021 GMR group signed a Memorandum of Understanding (Mou) with Airbus which will help them explore opportunities across aviation services, including aircraft maintenance, components training, and digital and airport services.


COVID-19 Led to Deep Decline in Line Maintenance Services Due to Suspension of Passenger Air Travel Services

In March 2020, the World Health Organization (WHO) worldwide declared the COVID-19 outbreak a pandemic. Since then, daily life and businesses across the globe has changed. Air transport and aviation industry were severely affected due to the pandemic since the very beginning of the crisis started. In 2020, according to International Civil Aviation Organization (ICAO) the airline faced approximately USD 371 billion loss in gross passenger operating revenues. Moreover, there was an overall reduction of air passengers (both international and domestic), ranging from 60% in 2020 compared to 2019. This overall reduction in airline business led to a deep decline in aircraft line maintenance services. The airline sector is expected to be smaller for years to come; it is projected that air traffic won’t return to the pre-pandemic level before 2024. The only hope that saved the line maintenance market was cargo and rescue flights operated amid pandemics. For Instance,

  • During the pandemic, Nearly 39,200 special repatriation flights carried 5.4 million citizens home after international borders closed during the pandemic in March 2020.

  • Moreover, Nearly 46,400 special cargo flights transported 1.5 million tons of cargo including, medical equipment and supplies to the rural areas in need during the height of the pandemic response.

“Embracing Advanced Technologies in Aircraft Maintenance to Propel Market Growth”

The aviation industry is witnessing significant progress in developing advanced technologies and using them while performing various maintenance activities. Airlines, engine manufacturers, MRO service providers, and airlines are keen to invest in these types of advanced technologies to facilitate their maintenance and production. For instance, the use of artificial intelligence in aircraft maintenance has led to a decline in errors in aircraft maintenance. AI can predict aircraft repair failure before any fault is identified. Key players, such as Ameco, STS Aviation Group, Inc., United Airlines, Inc., and others are making extensive use of AI AI-based systems and tools in line flight management. The growing implementation of intelligent AI-based solutions by companies will encourage market growth. In July 2021, GE Digital has entered into an agreement with Airbus and Delta TechOps in Digital Alliance for Fleet Health Monitoring and Diagnostics Solutions. GE Digital will bring its state-of-the-art forecasting software and in-depth engineering knowledge of aerospace systems integrated with Airbus cloud-based data platform and Delta-based performance and maintenance models. Together these companies will provide cost savings, network efficiency and increased shipping availability to 140 commercial airlines worldwide working with Skywise Core.


“Increase in Passenger Air Traffic to Boost The Market Growth”

The increase in passenger loads worldwide is one of the biggest opportunities for airline service providers and aircraft manufacturers. The concept of low-cost carriers and budget airlines is one of the major factors responsible for the expansion of this market. Budget airlines offer fares to passengers at an affordable rate which has led to an increase in air traffic worldwide. According to the International Air Transport Association (IATA), China will replace the U.S. as the largest passenger traffic worldwide by the end of 2024. China is expected to record additional 817 million passengers, which leads to a total of 1.3 billion air passengers. This will facilitate the aircraft line maintenance market growth during the forecast period. For Instance,

  • According to ICAO's preliminary compilation, 100,000 flights take off and land every day all over the globe. For Instance, the average length of a flight is two hours; that would mean that six million people fly somewhere every day. That's nearly 0.1% of the entire world's population.

“Subcontracting of Line Maintenance Services and operations to Fuel MarketGrowth”

 Airline operators across the globe are growing at a tremendous rate, which has led to an increase in costs for aircraft maintenance & repair, and MRO industry. Due to strong competition, sub-Contracting maintenance services has become a better option for many airlines. This new trend of sub-contracting provides the airline a window of cost reduction in terms of labor charges and maintenance cost. When airlines sub-contract, they are able to access additional resources in and parts from various different repair organizations around the world, which not only saves time but also improves operational efficiency.


“Delays in Aircraft Deliveries to Hinder Market Growth”

The backlog orders with aircraft manufacturers are among the major factors causing delays in the promised delivery of aircraft. Other than pending orders, the outbreak of coronavirus in early 2020 was a major obstacle for the entire aviation industry leading to huge losses, cancellation of orders, and delayed aircraft deliveries. As a result, the delivery of aircraft for commercial and airlines use in 2020 had a total of 723 aircraft, 42% less than 2019 and 55.3% less than 2018, as a reason the year 2020 marked the second consecutive year that witnessed decline in aircraft deliveries.

  • In April 2020, Airbus SE announced that have received 16 cancellations for the A220 series due to airliners being engaged in trimming down their fleet and staff cuts amid the COVID-19 pandemic.

  • In December 2020, the major OEM in the market, Embraer announced that its company commercial segment named, Embraer Commercial Aviation, witnessed a 75% reduction in aircraft deliveries during the first half of the year 2020 due to pandemic  as compared to the same period last year.
