Aviation’s Post‑COVID Rebound: How Manufacturers and MROs Are Powering a Global Ramp‑Up

The aviation sector has spent the past five years navigating one of the most turbulent periods in its history. COVID‑19 brought global operations to a standstill almost overnight, grounding 62% of the world’s fleet and collapsing maintenance, repair and overhaul (MRO) demand. Fleet inactivity, deferred maintenance, labour shortages, and supply chain disruption created a backlog of issues that is still echoing across the industry today.

Yet, out of this disruption has emerged one of the largest coordinated recoveries in modern aviation, with manufacturers and MRO organisations accelerating investment, innovation, and capacity expansion to meet surging demand.

Below is a strategic overview of how the sector is ramping up—and why challenges remain.

The Post‑Pandemic Surge: Demand Outpacing Supply

As aircraft returned to service in 2022–2023, demand for maintenance surged. The result was a multi‑year MRO capacity backlog, worsened by material inflation, part scarcity, and engineer shortages. Production lines at major original equipment manufacturers (OEMs) faced similar strain:

• Aircraft delivery backlogs now exceed 17,000 units, equating to 14 years of production at current rates.
• A global shortfall of 5,400 aircraft is forcing airlines to operate older fleets longer, significantly increasing maintenance complexity and cost.
• Engine turnaround times have grown by 30% for legacy engines and over 150% for new platforms like Leading Edge Aviation Propulsion (LEAP) and Geared Turbofan (GTF).

This demand surge means that MRO capacity must grow by more than 30% by 2035 just to keep pace. North America alone is projected to fall short by 48,000 maintenance workers by 2027.

Manufacturers Ramp Up: Overcoming Production Bottlenecks

Manufacturers have been hit by a perfect storm: labour shortages, disrupted supply chains, and production quality issues. Both Airbus and Boeing have been operating well below peak output, with delivery rates 30% behind historical highs in 2018.

Key constraints include:

1. Labour & Skills

A large portion of the engineering workforce retired or left the sector during the pandemic. Re‑hiring and training remains slow, especially for specialised production and manufacturing roles.

2. Supply Chain Fragility

Semiconductor shortages, casting delays, avionics bottlenecks, and the long‑term impact of Russian titanium sanctions continue to slow output. Recovery of materials such as aerospace‑grade titanium may take 2–3 years to normalise.

3. Quality Assurance Pressure

Recent production halts—particularly on the Boeing 737 MAX and 787—have resulted in heightened regulatory scrutiny, slowing deliveries but improving long‑term resilience.

To counteract these challenges, OEMs are:

• Expanding supplier networks and conducting more audits
• Onboarding regional suppliers to ease logistics dependency
• Investing heavily in automation, simulation, and digital inspection tools
• Increasing collaboration with MRO networks, sharing repair data and authorising more third‑party centres

Global Expansion of MRO Capacity

While manufacturing recovers, the MRO sector is undergoing its own transformation. Demand for airframe, component, and especially engine overhauls is surging as airlines operate older fleets to compensate for slow new‑aircraft deliveries.

Major Global Investments Are Underway

• General Electric (GE): Over $1B invested in new engine overhaul capacity
• Singapore Airlines Engineering: $242M expansion with Rolls‑Royce, nearly doubling engine capability
• FL Technics: Opening the Caribbean’s first independent Heavy maintenance MRO facility with plans to expand to 20 Bay capacity
• HAECO Xiamen: New 18‑aircraft hangar, the largest single span facility globally
• Ryanair: Increased in house maintenance capacity by 130% through expansion projects across multiple facilities. 21 new aircraft maintenance bays added with two new Engine overhaul facilities to open by 2029

These expansions are essential to alleviate mounting pressure on turnaround times and restore global maintenance resilience.

Innovating Out of the Crisis: Repair vs Replace

With part’s prices rising up to 20% YoY, OEM spares constrained, and logistics costs elevated, the industry is strategically shifting toward repair‑driven solutions:

1. Refurbishment & Advanced Repairs

Collins, Honeywell, and others are adopting adaptive machining, automation, and sophisticated inspection technology, cutting scrap rates by up to 50% and repair cost savings of up to 80%.

2. Parts manufacturer approval (PMA) & Part 21 Expansion

• Federal Aviation Administration (FAA)‑approved PMA components offer 30–40% savings
• Part 21 engineering departments are developing custom repairs independent of OEM manuals
• Additive manufacturing (3D printing) is accelerating parts availability

3. On‑Wing Repair Growth

OEM mobile teams (Pratt & Whitney, GE, MTU) are expanding to avoid unnecessary shop visits, reducing downtime and material consumption.

4. Circular Economy Growth

Up to 85% of an aluminium airframe is recyclable, and composite recycling technologies are rapidly evolving. The used serviceable material (USM) market is projected to reach up to $10B by 2030, with teardown specialists like Ecube and Tarmac Aerospace processing hundreds of aircraft annually.

Digital Transformation Accelerating the Ramp‑Up

Digitalisation, once slow in aviation MRO, has surged post‑COVID, driven by cost pressure and the need for efficiency:

• AI‑powered inspections, including digital twin predictive analytics, enhanced borescope analysis, and robotics developments
• Automated planning and task distribution via enterprise resource planning (ERP)/ manufacturing execution system (MES) integration
• Real-time maintenance ecosystems, linking AMOS, AVIATAR, and flydocs
• Drone inspection investment to improve safety and efficiency
• Virtual assistants supporting engineers with instant fault diagnosis

These technologies are reducing bottlenecks, improving forecasting, and raising throughput without equivalent staffing increases.

Workforce Recovery: Rebuilding the Talent Pipeline

The industry faces a demographic cliff: the average licenced aircraft engineer (LAE) age is 54, with 20% retiring within five years. In response, aviation organisations are investing heavily:

• Record breaking apprenticeship scheme intakes Globally
• Regulatory changes to facilitate Fast-track training, combining academic and practical pathways to reduce the industry skills gap
• Increased Recruitment from non‑aviation sectors and the armed forces
• Upskilling programmes for AI‑diagnostics, digital tools, and data literacy

This workforce transformation is essential to support both manufacturing ramp‑ups and MRO expansion.

Looking Ahead: Recovery With Caution

The aviation sector is more confident than at any point since the pandemic. Roughly 70% of aerospace companies now feel prepared for production and maintenance ramp‑ups—double the confidence level of 2024.

However, key challenges remain:

• Capacity gaps in both OEM and MRO supply chains
• Persistent labour shortages
• Long engine and part lead times
• Financial constraints as operators deal with inflated costs
• Operational risk with a younger, less experienced workforce

Conclusion

COVID‑19 created unparalleled disruption across aviation, but it also forced a reinvention. Manufacturers and MROs are emerging stronger—more digital, more collaborative, and more innovative.

The next five years will determine the success of this transformation. Capacity growth, supply chain resilience, digital adoption, and workforce development will shape how effectively the industry can meet unprecedented demand.

Aviation is recovering—steadily, strategically, and with renewed momentum.
