Navigating Turbulence: The 2026 Aviation Supply Chain Landscape (Backlogs, Engines, MRO & SAF)
Navigating Turbulence: The 2026 Aviation Supply Chain Landscape
Backlogs remain elevated, engine shop visits are stretching timelines, and airlines are paying the price of keeping older aircraft flying. Here’s what’s structurally constrained, what is improving, and what a realistic 12-month outlook looks like in 2026.
Executive Summary: What Matters Most in 2026
- Aircraft order backlogs remain above 17,000, translating into a multi-year wait at today’s build rates.
- Delivery shortfalls have accumulated beyond 5,300 aircraft, keeping fleets older and increasing maintenance intensity.
- Engines and components are the bottleneck within the bottleneck: shop capacity, parts availability, and turn-times are shaping schedule reliability.
- Supply chain friction has a direct price tag: airlines face multi-billion-dollar impacts through fuel efficiency delays, maintenance and leasing costs, and higher inventories.
- SAF grows, but remains constrained: production rises in 2026, yet pricing and policy design continue to influence adoption pace.
Bottom line: 2026 is not a “return to normal” year. It is a year of managed constraint—where winners combine disciplined planning, diversified sourcing, and faster technical decision-making across maintenance, parts, and fleet strategy.
1) Persistent Constraints Shaping the Aviation Supply Chain
1.1 Record Backlogs and Delivery Gaps Are Keeping Fleets Older
The commercial aviation system is still absorbing a delivery shock: OEM output has improved, but demand has outpaced supply for several years. The global order backlog sits above 17,000 aircraft, and the cumulative delivery shortfall exceeds 5,300 aircraft. The practical result is simple—airlines, lessors, and operators keep aircraft in service longer, defer cabin or performance upgrades, and run maintenance programmes at higher intensity to preserve dispatch reliability.
1.2 Engines, Materials, and Skilled Labour Remain the “Hard Limits”
Even when airframes are available, engines and component availability can dictate capacity. Shop visit timelines and parts availability influence utilisation, spares strategy, and even network planning. At the same time, the industry continues to face skilled labour constraints across manufacturing and maintenance, especially for specialised roles (licensed engineers, machinists, composite technicians, avionics specialists, and inspectors).

2) The Real Cost: Why “Supply Chain” Shows Up in Operating Results
In aviation, supply delays convert into operating costs. When new aircraft arrive late, airlines miss fuel efficiency gains and keep older aircraft flying. When engines spend longer in maintenance, leasing and spare engine demand rises. When parts lead times widen, inventories increase to protect dispatch reliability.
| Cost Driver | What It Looks Like Operationally | Why It Matters |
|---|---|---|
| Delayed fleet renewal | Older aircraft operated longer than planned | Higher fuel burn + maintenance events; lower availability |
| Engine/MRO constraints | Longer shop turns, parts shortages, capacity limits | Spare engine leasing costs; schedule and utilisation pressure |
| Inventory expansion | More rotable and consumable stock on hand | Working capital increases; warehousing and repair loop complexity |
| Certification bottlenecks | Slow onboarding of alternates / PMA pathways | Reduced flexibility during disruptions |
Industry analysis has quantified these effects for 2025 at over USD 11 billion in additional costs, driven by delayed fuel savings, higher maintenance, excess engine leasing, and larger inventories. Those pressures do not disappear overnight—many roll into 2026 planning.
3) Building Contingencies: What Resilient Operators Are Doing Differently
3.1 Diversify Supply Without Diluting Airworthiness Discipline
- Multi-source critical parts (where certification pathways allow), including approved alternates.
- Near-shore selectively for items where lead-time volatility is the bigger risk than unit price.
- Dual-track repair loops: align rotable pools and repair vendors to prevent single-vendor lock-in.
3.2 Treat Engines as a Board-Level Planning Variable
- Build shop-visit forecasting into network planning and fleet availability models.
- Use condition monitoring + borescope planning to avoid surprise removals.
- Secure engine leasing / spare capacity options early when the market tightens.

FAQ: Aviation Supply Chain in 2026
Why is the aircraft backlog still so high in 2026?
Demand recovered strongly while manufacturing and the wider aerospace supply base faced labour, parts, and capacity limits. Deliveries improved, but not fast enough to close the gap created over several years—so the backlog remains structurally elevated.
What is the biggest bottleneck: airframes or engines?
In many cases, engines and components are the binding constraint—because shop capacity, parts availability, and turn-times directly affect aircraft availability and schedule reliability, even when airframes are delivered.
