Effective aircraft maintenance planning requires handling intricate schedules of inspections, repairs, and component overhauls across an airline’s fleet, all while minimising disruption to flight schedules and complying with strict regulations.
Research by the Boston Consulting Group (BCG) shows that since the pandemic began, maintenance-related delays increased by 2-3 times, and technical dispatch reliability reduced by 50%. For large carriers, the financial impact of this scale of decline can exceed $100 million to $200 million per year due to lost revenue, passenger compensation, and network effects.
To keep things running smoothly, organisations must adopt effective aviation maintenance planning practices. This article outlines the current challenges affecting operators and how to tackle them.
Challenges in Aircraft Maintenance Planning and How MRO Software Helps
Doing the right maintenance work at the right time prevents small issues from growing into major problems, helping to reduce delays and safety risks. However, several factors are making this difficult at the moment.
Parts Shortages and Inventory Control
Aside from the inherent challenges of managing parts at the required scale, here are some current constraints.
Aircraft and Parts Backlog
Ongoing delays in aircraft and spare parts deliveries have created a significant backlog. IATA notes that the situation has been impacted by tariffs on metals and electronics due to trade tensions between the US and China. There’s also a shortage of skilled labour in engine and component manufacturing.
Loss of Senior Supply Chain Talent
BCG notes that the loss of experienced supply chain personnel during the pandemic has weakened capabilities, and this undermines operators’ ability to anticipate parts demand.
Misalignment with Network Changes
BCG also notes that traditional parts distribution networks haven’t kept up with evolving airline networks, leading to mismatches between where parts are located and where they’re needed.
How Aviation MRO Software Helps
IATA recommends improving supply chain visibility across all supplier levels and using data more effectively to pool spare parts, optimise inventory, and reduce downtime.
Aviation maintenance software helps through its inventory management features. For example, OASES has a Materials Management module that gives users robust control over parts, equipment, and orders. Its automatic shortage management prevents unwanted surprises – in fact, parts can be reserved automatically when a work order is created thanks to its integration with planning modules.
Full traceability of all items is maintained. Data logged includes their batch and serial number, origin, repair history and current location.
Overall, the module provides comprehensive control and oversight of everything to do with parts and tooling.
Ineffective or Outdated Aviation Maintenance Planning Systems
Many airlines still rely on legacy planning systems – and processes – that were designed for less complex environments. BCG notes that where processes were traditionally more manual, the departure of experienced planners has left gaps in understanding nuanced maintenance cycles and regulatory demands.
Legacy processes and systems struggle with the volume and variability of today’s maintenance requirements. They struggle to adapt to changing priorities without human intervention, and this traps organisations in a reactive cycle.
Technician shortages make it harder for MROs to meet demand. BCG notes that many junior technicians have considerably less experience, and 10-15% lower productivity levels, than their senior predecessors. This leads to lower throughput and longer task completion times, making effective planning and resource allocation even more critical.
How Advanced Aircraft MRO Software Helps
The right planning tools provide the framework to manage line maintenance and heavy maintenance needs for entire fleets with ease.
Modern MRO software platforms consolidate all tasks, requirements, and scheduling data in one place, and keep detailed logs of all maintenance activities. Some systems automate work package creation based on forecasted tasks and incoming regulatory requirements.
Integration with Flight Ops and Other Data Sources
One of the most critical integrations is between maintenance planning and flight operations systems. The best MRO software offers APIs to synchronise plans with live flight schedules so teams can instantly respond to updates and optimise resource allocation.
Line maintenance planning tools should ingest data from sources like Electronic Flight Bags (EFBs), tech logs, and e-enabled aircraft systems in real time. This way, information on recent flight hours, cycles, or MEL items can flow directly into the maintenance software.
Visibility and Real-Time Updates
Cloud based MRO software provides real-time visibility into the status of every task. It clearly shows which tasks are due, which aircraft are in maintenance, what work has been completed, and any open defects. Some systems enable mobile or remote access, meaning updates from the hangar floor are reflected system-wide.
To summarise, MRO software gives operators absolute control over all maintenance activities – upcoming and in-progress – at all times. It provides absolute visibility, which is the key to preparedness; to being able to adapt to the unexpected with minimal disruption.
Other Considerations for Effective MRO Maintenance Planning
Resource and Workforce Management
A solid maintenance plan lays the foundation for effective resource and workforce management. When maintenance activities are defined and scheduled in advance, organisations can allocate technicians, tools, ground equipment, and hangar space in a structured and realistic way.
Planning maintenance capacity ahead of time – using data – helps prevent overallocation of certain technicians, reducing unnecessary overtime. Operators can assess whether they have sufficient workforce and facilities to meet upcoming requirements, or whether adjustments are needed before constraints start affecting operations.
Careful planning also reduces the risk that too many junior technicians are working simultaneously without more experienced staff available.
Flexibility is key. Reserving a portion of resource capacity for unscheduled maintenance allows organisations to respond to unexpected defects without creating further schedule disruptions. This is essential for handling AOG situations while keeping the wider maintenance plan intact.
Condition-Based and Predictive Maintenance Approaches
Data-driven planning can greatly improve effectiveness by incorporating reliability and real-world performance data into decisions. For example, if a component is failing more often than expected across the fleet, planners might schedule more frequent inspections or pre-emptive replacements.
Predictive maintenance has been shown to reduce costs by 12-18% and unplanned downtime by 15-20%. Even without AI-driven tools, planners can use trend and condition monitoring rather than fixed schedules to prevent failures and safely use components for their full useful life.
Decision Support
Data has much to offer beyond predictive maintenance. Some MRO platforms have simple reporting functions, but more advanced systems have built-in BI tools that support immediate operational needs and strategic decision-making.
These tools allow operators to analyse maintenance operations from multiple angles. For example, inventory data can be examined alongside planned work to identify upcoming material shortages, excess stock, or long lead-times that could affect maintenance schedules. Warranty information can be linked to defect history and removals, helping teams detect recurring issues and ensure eligible claims are not missed.
Decision support also extends to financial oversight. Combining activity data with cost information gives organisations better visibility into maintenance spend, cost drivers, and trends over time.
Getting the Most From MRO Data
To get real value from MRO data, that data must first be reliable. This starts with a clear data management strategy that ensures information is properly organised, structured, and routinely cleansed.
Using standardised data formats across systems is essential. Well-designed integrations reduce manual data entry and the risk of inconsistencies creeping in.
Regular data audits also play a key role, allowing organisations to check that information within their maintenance and engineering systems is always accurate.
Left unchecked, small inaccuracies can accumulate, ultimately leading to flawed analysis and poor planning decisions.
Periodically Review Planning Effectiveness
Airline maintenance planning can be continually improved. Planners should regularly review the execution of the maintenance plan versus expectations. Post-maintenance audits can reveal if certain checks always take longer than planned or if specific causes of downtime could be reduced or eliminated.
Using robust analytics and reporting tools, organisations can monitor KPIs like schedule adherence, deferral rates, and cause of delays. This data helps in refining future plans.
Improving Station Capabilities
Finally, maintenance station capabilities need to develop in line with today’s fleets and operating models. In many networks, key stations are overloaded, while maintenance tasks aren’t always carried out where they can be completed most effectively.
A data-led approach allows operators to better align station locations with flight schedules, ground time, and actual maintenance demand. Reviewing ground time assumptions is equally important, as overly tight schedules can leave insufficient time for routine work and increase the risk of disruption.
Strengthening the capabilities of line stations is also critical for reducing reliance on major (perhaps overburdened) hubs and improving overall resilience.
Conclusion
Effective aircraft maintenance planning is critical for airlines, CAMOs, and MRO providers to achieve the goals of safety, efficiency, and optimal aircraft availability. The complexity of today’s aviation industry makes manual planning approaches impractical, which is why modern MRO software is crucial.
Solutions like OASES provide comprehensive planning capabilities that strengthen regulatory compliance. They automate routine tasks, offer real-time oversight, support predictive maintenance, and ensure that all the moving parts stay in sync.
The result is a maintenance operation that is proactive and optimised for minimal disruption.
