Moving to Net Zero: Your next step in decarbonisation
ArticleReady for Net Zero? Learn how to turn early climate action into a credible, future-proof strategy that drives long-term value.

Continued demand for air passenger travel is increasing pressure on aerospace companies coping with operational and cost challenges. OEMs are facing a variety of issues—supply chain disruptions, quality control, labour shortages and more—that have led to delays and shortfalls in aircraft delivery.
As aircraft demand outstrips supply, airline lessors must manage the residual risks of having older aircraft, even as their portfolio valuations and lease rates increase. These risks, such as aging technology, affect potential portfolio sale prices as well as a fleet’s ability to reach key pefromance metrics, including sustainability objectives.
Against this backdrop, Ireland remains the global centre for aircraft leasing, with 14 of the top 15 lessors located here and one out of every four aircraft leased from here. At Grant Thornton, we understand aviation challenges, and our team of aviation advisors, finance experts and technical engineers provide cross-functional, tailor-made solutions across industry.
The aviation industry is multifaceted—and so is our aviation team. Our accountants understand the contracts, and our engineers know the metal. We’re the partner you can trust to deliver quality, every time.
CMS data is the engine room of the aviation industry. Our team speaks the technical language, managing your data accurately and completely. Downstream users save time while getting the most from data they can rely on.
Slow, opaque models result in poor decision-making and missed dealmaking opportunities. Our standardised approach to model builds helps you stay competitive, ensuring you get the information you need when you need it.

Our commitment to delivering excellent results drives our success and yours. As the go-to service provider for global lessors, our aviation team manages over 1,400 leases. We use a process-oriented delivery model that removes business burdens and allows you to focus on core value-add activities.
Combining deep technical knowledge from industry and practice, our integrated team services 13 of the top 15 lessors. We provide best-in-class model builds, data quality reviews, data migration/system implementations, internal audits, transaction services and more.
Your contract management systems (CMS) data is your engine room, but managing it can be time-consuming. Urgent business needs often lead to incomplete or inaccurate data inputs. When downstream users can’t trust data quality, it creates long-term problems and duplicates effort.
Our accountants effectively integrate day-to-day CMS activities with the associated financial activity in the general ledgers. Our internal auditors ensure our processes have embedded controls and a high degree of assurance while our technical engineers bring the MRO knowledge necessary for quality service.
That cross-functional expertise is how we guarantee a lease management service where all aspects—technical, operational and contractual—are best in class.
We manage more than 1,400 MSNs and achieve service continuity by putting in place strong, comprehensive processes. Our aviation lease services include:
Without advanced planning, data migration and systems integrations go awry. We begin each migration and integration by mapping the project, ensuring the plan to move from the source system to the new system is sufficiently detailed with the key dependencies identified.
Drawing upon our deep understanding of the underlying data, we pinpoint and resolve gaps to ensure data in the new system is complete and accurate.
We also support you in designing and running large data validation processes—from data input to postings on the general ledger. By applying our modelling expertise, we automate much of the process—ensuring a rigorous, efficient transition.
Having reviewed over 1,500 lease contracts and associated operational data, we draw on our experience and expertise to provide assurance over your CMS data and reduce exposure in divestment and default scenarios. You gain:
Better, faster information results in better decision-making. When models lack transparency, users can’t trust the underlying data, and it’s hard to make informed decisions. Waiting on outputs from slow models can result in costly delays, missed opportunities and deal-related oversights.
Having a best-in-class model has huge consequences for your dealmaking ability. Our standardised approach to model builds and reviews helps you stay competitive. We ensure you get the information you need when you need it.
We build models that fully use CMS inputs and outputs. When needed, we also embed the processes required to run and maintain a model as part of business-as-usual, avoiding key-employee dependencies and providing comprehensive documentation about model-run procedures, governance, roles and responsibilities. We provide transparency on:
In the complex, fast-paced aviation sector, strong internal controls are critical for mitigating a dynamic risk environment. Partner with us to strengthen governance, enhance transparency and address the challenges that arise from rapid innovation and regulatory scrutiny.
