MRO (Maintenance, Repair & Overhaul) Supply Chain & Manufacturing Challenges Aviation Safety & Regulation Airlines

IATA charts a four-stage pathway to ease engine MRO bottlenecks across the airline aftermarket

IATA has published a new report focused on engine maintenance, repair and overhaul (MRO) bottlenecks that have constrained fleet availability in recent years. It outlines a “four stage” solution aimed at improving throughput and reducing knock-on disruption from constrained shops and parts flows.

Briefing

What Hype is tracking

The IATA report reframes today’s engine constraint as a multi-step bottleneck problem—useful for planning capacity, reliability initiatives and contract terms for near-term fleet availability.
It adds structure to the same operational pain carriers have been flagging publicly, including engine shortages as a major limiter on growth (United CEO Scott Kirby: engine shortages will be the “biggest constraint”).
It complements ongoing aftermarket investment and process moves—such as engine MRO capacity expansion tied to parts and logistics tightening (GE expands engine MRO footprint and tightens supply chain to cut turnaround times)—by spelling out what else needs to change to relieve systemic throughput pressure.
