Engine maintenance, repair, and overhaul shops across the globe are navigating a crisis that has quietly reshaped the economics of commercial aviation. Turnaround times for engine shop visits have surged by more than 150 percent for new-generation platforms, stretching what was once a 60-day process into a four-to-six-month ordeal. Airlines, lessors, and MRO operators are feeling the pressure in lost revenue, grounded aircraft, and strained maintenance budgets. Behind these delays lies a complex web of supply chain disruption, workforce shortages, and data fragmentation that no single process fix can resolve. But a growing number of shops are discovering that the path to shorter wait times does not begin on the factory floor. It begins with how they manage information.

Engine MRO now accounts for 45 percent of total commercial aviation aftermarket spend. With demand forecast to exceed capacity by 15 to 20 percent through 2030, the question is no longer whether shop management practices must change, but how fast.
THE WAIT-TIME TRAJECTORY
How Engine Shop Turnaround Times Doubled in Five Years
The timeline below traces how a combination of deferred maintenance, supply chain shocks, and unexpected durability issues on new-generation engines pushed shop turnaround times well beyond historical norms. Each phase added a new layer of complexity that traditional shop management tools were not designed to handle.
2019
40-60 days
Pre-Pandemic Baseline
Engine shop visits operated on predictable schedules. Parts supply was stable. Workforce levels were adequate. Shop managers planned around known intervals.
2021
60-90 days
Deferred Demand Hits
Pandemic-related deferrals created a bow wave of shop visit demand. At the same time, supply chains began to constrict. Lead times for parts stretched from weeks to months.
2023
80-200+ days
New-Gen Durability Emerges
LEAP and GTF engines entered their first overhaul cycles earlier than expected. Powder metal contamination on GTF engines and nozzle issues on LEAP added hundreds of unscheduled shop visits.
2025
80-300+ days
Capacity Crunch
Parts lead times reached 20-40 weeks. Over 22,000 technician positions remain unfilled. MRO capacity lags 15-20 percent behind demand. Slot wait times stretch 2-6 months.
THE ROOT CAUSES
Four Drivers Behind the Engine MRO Backlog
The 150 percent increase in turnaround times is not the result of a single failure. It is the compounding effect of four structural pressures that have built up simultaneously across the engine maintenance ecosystem.
01
Parts Supply Chain Disruption
Lead times for critical engine components have stretched from 4-6 weeks to 20-40+ weeks. New parts production cannot keep pace with demand, and used serviceable material supply has tightened as aircraft retirements slow. Engine turnaround time is now dictated by parts flow, not shop capacity.
20-40+ week parts lead times
02
Skilled Technician Shortage
The global MRO sector faces a projected shortfall of over 22,000 technicians by the end of 2026. More than 40 percent of current technicians in some regions are over 60. Training pipelines are not scaling fast enough to replace the experience leaving the workforce.
22,000+ technician gap by 2026
03
New-Generation Engine Durability
LEAP and GTF engines require repairs in far greater numbers than anticipated. The GTF powder metal contamination alone has grounded hundreds of aircraft. These unscheduled events have flooded shops with work that was not factored into capacity plans.

04
Fragmented Data and Planning
Most engine shops still manage work orders, parts inventory, workforce scheduling, and customer communications across disconnected systems. Without a unified data layer, managers cannot see constraints before they become delays. Reactive firefighting replaces proactive planning.

BY THE NUMBERS
The Financial Weight of Every Extra Day in the Shop
When an engine sits on the shop floor beyond its scheduled return date, the cost compounds across multiple dimensions. These three numbers capture the scale of what is at stake for operators, lessors, and MRO providers alike.

Total engine maintenance demand projected 2025-2034
The next decade will see nearly 700 billion dollars in engine MRO activity. Shops that cannot optimize throughput will lose market share to those that can.

Engines represent the single largest cost center in airframe maintenance. Every efficiency gain in engine shop management multiplies across the entire MRO budget.

Demand will continue to outrun supply. The operators who close this gap with better data and planning, not just more floor space, will define the next generation of engine MRO.

THE INTELLIGENT SOLUTION
How Data-Driven Shop Management Reverses the Trend
The shops that are pulling ahead are not those with the newest test cells or the largest floor space. They are the ones that have connected their data. When parts availability, workforce capacity, work scope, and customer deadlines live in a single system, the 150 percent wait time problem becomes solvable in measurable increments.

FAQ
Common Questions About Engine MRO Shop Management
How does better data management actually reduce engine shop turnaround times?
The primary driver of extended turnaround times is not repair complexity alone. It is the time spent waiting for parts, waiting for decisions, and waiting for information. When an engine is torn down and findings reveal unexpected damage, a traditional shop begins a manual process of checking inventory, calling suppliers, and rescheduling downstream work. In a data-driven shop, that same finding triggers an automated availability check across inventory, open orders, and approved vendor lists. The system surfaces options in minutes, not days. Over the course of a 120-day shop visit, eliminating these information gaps can reduce total time by 20 to 30 percent.
Can a digital shop management platform integrate with existing ERP and maintenance systems?
Yes. iFactory's Engine Shop Module is designed to sit alongside existing ERP, maintenance tracking, and financial systems. It does not require replacement of your current infrastructure. The platform ingests data from work order systems, parts inventory databases, and workforce management tools to create a unified operational view. API-based integration means that data flows both ways. Your existing systems continue to function as they do today, while iFactory adds the real-time visibility, predictive analytics, and automated compliance that disconnected systems cannot provide on their own.
What measurable ROI have engine shops seen after implementing data-driven management?
MRO facilities using integrated shop management platforms report a 20 to 30 percent reduction in average shop visit time, a 25 percent improvement in capacity utilization, and a 50 percent reduction in time spent on status reporting and manual documentation. Compliance audit preparation, which traditionally requires days of document gathering, is reduced to minutes. For a mid-size engine shop handling 50 to 80 shop visits per year, these improvements translate into millions of dollars in recovered revenue and reduced operating costs within the first year of deployment.
TAKE CONTROL OF YOUR ENGINE SHOP
150% Wait Times Demand More Than a Faster Wrench
The engine MRO capacity crunch will not resolve itself. Parts lead times are not returning to pre-pandemic levels this year. The technician gap is widening. But the shops that connect their data, automate their planning, and gain real-time visibility into every engine in process will be the ones that deliver on time while competitors fall further behind. iFactory gives you that visibility in weeks, not quarters.
