Critical MRO Capacity Constraints and Industry Bottlenecks

The aviation MRO sector is currently experiencing unprecedented capacity constraints, creating operational challenges for airlines worldwide. According to Bain & Company, MRO demand is expected to peak in 2026, with capacity shortages already turning engine shops into critical bottlenecks. These constraints are the result of several converging factors: post-pandemic recovery, increased maintenance needs for new-generation engines, and supply chain disruptions affecting parts availability.

The COVID-19 pandemic led to the grounding of about 60% of the global fleet and a 45% drop in MRO spending. Deferred maintenance during this period has created a substantial backlog, compressing maintenance windows as aircraft return to service. New-generation engines like the LEAP, while more efficient, have required more frequent repairs than initially projected, partly due to issues such as powder metal contamination, placing additional strain on MRO providers.

Supply chain disruptions have compounded these challenges, with parts shortages forcing maintenance providers to rely on scarce used serviceable materials. For newer engine types like the LEAP, the limited installed base constrains alternative parts sourcing, further extending shop visit durations. Some LEAP engines are now experiencing maintenance stays exceeding 200 days, far beyond the traditional 60-70 day average, leading airlines to maintain larger spare engine inventories and absorb higher direct and opportunity costs.

“Industry analysis reveals some LEAP engines are experiencing shop visit durations exceeding 200 days, significantly beyond the traditional average.”

To address these issues, both engine manufacturers and independent MRO providers are investing heavily in capacity expansion. GE Aerospace has announced $1 billion in MRO investments, while Safran Aircraft Engines has committed over €1 billion to develop its global LEAP MRO network, with much of the facility expansion slated for 2025 and 2026.
