aircraft maintenance cost tracking outsourcing

Tracking an aircraft maintenance cost can be intimidating, considering millions of dollars are being accounted for. Hence, why not rely on an aircraft maintenance cost tracking outsourcing service for easy and cost-efficient MRO accounting?

The reason for relying on outsourcing service is because accounting MRO (Maintenance, Repair, and Overhaul) is prone to be complex and challenging. From risk of errors, inefficient maintenance, lack of real-time tracking process, and unplanned downtime.

Since aircraft maintenance represents 10–15% of the total airline operating costs, it is better to leave this to the experts specialized for accounting MRO. But if an airline already has its own accounting team, this article will provide information about its challenges and solutions.

The Complexity of MRO Cost Management

There are plenty of reasons why MRO cost accounting can be complex. First, while that 10–15% seems little, aircraft maintenance still costs millions because airlines need to perform:

  • Routine maintenance that needs to be done between flights or overnight. This includes daily routine and minor repairs if needed on any of the aircraft.
  • Heavy maintenance that involves heavy labor usage and extensive planning. This includes C check and D check, which involves system testing, structural inspections, and replacing parts.
  • Preparation of the parts for aircraft maintenance. This can include rotables, expendables, surplus, and consumables for aircraft.

Second, it’s the complexity of cost allocation from such maintenance. Airlines will need to account for labor, materials, overhead expenses, and any contracted services.

Lastly, airlines also need to follow either IFRS (International Financial Reporting Standards) or the United States’ GAAP (Generally Accepted Accounting Principles) rules.

These regulations need to be followed when accounting for asset capitalization (like when upgrading or fixing an aircraft) and routine expenses (like routine maintenance).

MRO Accounting Best Practices & Systems

Understanding how complex MRO cost accounting can be, airlines need to follow the best method of doing it. It can range from doing an accurate cost allocation to using modern platforms to track MRO & assets properly.

Activity-Based Costing (ABC) for Accurate Cost Allocation

Every aircraft has its own maintenance cost tag. Some require heavy part replacements, and some just need routine maintenance. The problem is if the airline averages them when doing MRO accounting, which is inaccurate.

Therefore, activity-based costing is needed to make sure a maintenance cost is accurately accounted for to all the aircraft. While this may look unimportant, an accurate cost allocation can also help airlines spot cost-inefficiency in maintenance.

Integrating Modern Enterprise Software for MRO & Asset Tracking

In the modern, digital era, anything can be eased by utilizing modern ERP (enterprise resource planner) software, including MRO accounting. Here’s some of the best software that airlines can use to track MRO & aircraft assets:

  • AMOS is customizable aviation software that can control MRO costs, generate invoices, determine stock value, and, better yet, easily integrate with the airline's financial accounting system.
  • Ramco is a cloud-based asset tracker with AI capabilities to monitor aircraft assets, analyze data to forecast maintenance, and generate audit trails.
  • TRAX is a real-time software that can track MRO & airline fleet management, which can help airlines account for their aircraft maintenance costs.

Understanding Key Metrics That Are Essential to MRO Accounting

In order for optimal MRO accounting & aircraft asset tracking, airlines need to evaluate key metrics. These metrics can help airlines to manage their maintenance cost and the aircraft’s reliability:

  • Maintenance cost per flight hour, which is based on the type of aircraft and how many costs are needed for every hour the aircraft is flying.
  • Maintenance cost per flight cycle, which is based on the type of aircraft and how many costs are needed for each take-off and landing.
  • Deferred defects %, which is based on any known issue in the aircraft that has been detected but will be repaired later. The lower the %, the better.

Cost Tracking Challenge & Solutions

Since MRO cost management can be managed by proper cost tracking, it’s obvious that this needs to be done. However, airlines will face these cost-tracking challenges, which, fortunately, still have their solutions:

Work Order Management

Considering the complexity, aircraft maintenance work order accounting should be managed properly. The reason is because there’s a challenge during this work order management.

To put it simply, there can be a problem with limited aircraft resources, delayed work because of constantly changing work priorities, financial data inaccuracy because of improperly accounted work details, etc.

All of these problems can lead to overstated or understated maintenance costs. So, to avoid this, airlines need real-time tracking of work orders from their initiation to completion for better cost tracking.

Parts Inventory System

Another challenge with cost tracking also comes from how airlines store their aircraft parts and materials. For example, rotables can be used as spare parts multiple times, which have their own consumption costs. 

To tackle this challenge, airlines are usually implementing RFID (radio-frequency identification) tags on aircraft parts. RFID tags have a serial number tracking system that can also be integrated with ERP systems.

Major Maintenance Events

As stated before, heavy maintenance like a D check requires serious overhauls and full airframe checks. This particular maintenance can be challenging because it takes weeks, requires work orders, needs inventory planning, and tracks all the costs.

So, the solution here is to use modern enterprise systems that have already been explained above. By using automated MRO and aircraft asset tracking systems, airlines can finally focus on doing major maintenance.

Using Aircraft Maintenance Cost Tracking Outsourcing from the Philippines

The alternative choice for airlines is outsourcing the aircraft maintenance cost tracking. A Philippines-based outsourcing service, Global Virtuoso (GV), can provide such great assistance because of these benefits:
