Aircraft maintenance, repair, and overhaul (MRO) is critical to the aircraft lifecycle. It includes scheduled maintenance to make the aircraft airworthy continuously and unscheduled or unplanned maintenance due to damage, component and engine failures, necessary changes, and improvements to the cabin interior, systems, and other components. Aerospace and defense MRO organizations can be categorized as airline or operator MROs, independent or third-party MRO organizations, and OEM MRO organizations that provide MRO Services. SMEs play an insignificant role in OEM MRO services and fall primarily in the independent MRO sector.

Product Insights

The global aerospace defense MRO market is divided into engine, airframe, line, and component. The engine segment is responsible for the largest market share and is anticipated to grow at a CAGR of 5.5% over the forecast period. The maintenance of aero engines is one of the key security issues for keeping airplanes secure and functional. The requirement to protect the environment from pollution and adhere to regulations of FAA and EASA while enhancing the performance of aircraft engines are critical factors to be considered during airplane engine MRO. In addition, aircraft engines require to produce more power while consuming less fuel. This can be achieved by enhancing the efficiency of aircraft engines and maintaining them properly.

Aircraft airframes require heavy maintenance. Airframes comprise multiple critical flight control systems that offer high pitch and roll for carrying out aircraft operations such as take-off and landing. As a result, aircraft operators must ensure that these systems are highly efficient or productive. In April 2018, Airbus launched a project, Hangar of Future (HoF), for effective airframe MRO services. This project combined various advanced technologies to digitize and automate airframe maintenance activities to increase the efficiency of overall aircraft maintenance processes.

Application Insights

The global aerospace defense MRO market is segmented into narrow-body aircraft, wide-body aircraft, regional aircraft, and others. The narrow-body aircraft segment owns the highest market share and is expected to grow at a CAGR of 5.4% during the forecast period. A single aisle of seats characterizes a narrow-body aircraft. It is a small aircraft often used to operate short-haul international and domestic flights. It can carry as few as four passengers to as many as 300. In addition, several companies are investing in the aerospace and defense MRO market owing to the growing demand for narrow-body aircraft MRO services. For example, in May 2021, ST Engineering and Singapore investment fund Temasek created a joint venture dedicated to leasing cargo aircraft to meet the growing demand for aircraft MRO services from the global market.

Wide-body airplanes are twin-aisle planes that can carry many passengers and are usually employed for long-haul and medium-haul trips. These planes feature two aisles in each cabin and have a capacity of 200 to 850 people. The rise in long-haul routes with heavier traffic, typically connecting foreign locations, is the cause of the rising need for wide-body aircraft MRO. In addition, many new wide-body aircraft MRO centers have recently been set up in numerous countries. This increases OEMs' participation in the wide-body aircraft MRO service field. The rapid aircraft fleet expansion and the increased focus of OEMs on providing aircraft MRO are expected to add to the market growth.

End-User Insights

The global aerospace defense MRO market is bifurcated into commercial aviation, business and general aviation, military aviation, and others. The commercial aviation segment is the highest contributor to the market and is projected to grow a CAGR of 5.8% over the forecast period. Over the last two decades, commercial aviation maintenance models have evolved significantly. The market is expected to grow with the increase in fleet size, rapid urbanization, GDP growth of emerging economies, increasing tourism, higher penetration of low-cost carriers (LCC), and compulsory maintenance programs for aging aircraft. Further, a rise in the demand for cargo services due to increased international trade ties is anticipated to fuel the expansion of the commercial aviation MRO market during the forecast period.

Business and general aviation aircraft comprise light planes with low take-off weights for personal, corporate, and short-haul commercial transportation, such as air taxis and commuter airliners. These aircraft can be divided into three categories: turbofan, turboprop, and piston-engine aircraft. The business and general aviation MRO is driven by various factors, including aging business jets, demand for customization in private aircraft, refurbishment, and the preference of customers to revamp interiors with attractive materials, furnishings, colors, and other custom touches to make their cabin interiors unique.
