Find out why our clients continue to work with us and the level of support we offer
TGIS Aviation was contacted by a Lessor to manage a V2500 shop visit. The engine had been repossessed by the Lessor.
TGIS Aviation recently assisted a start-up airline, which was in the process of selecting up to four aircraft to launch their new operation.
During lease negotiations on behalf of airline clients, TGIS Aviation was asked to review the operational costs of two Trent 772B engines installed on an A330 aircraft.
Trish Gray, Engine Expert Witness specialist at TGIS Aviation, supported an airline as an independent Expert Witness for a case where a Lessor prematurely repossessed three A320 aircraft (note: the airline remains in operation).
At TGIS Aviation, we specialise in supporting clients through time-sensitive and complex aircraft transition projects.
“TGIS provided exceptionally experienced engineers who seamlessly integrated into our team,”
Our team is made up of highly experienced specialists that have worked for Airlines, OEMs, Leasing Companies and MROs. This means we can focus on a specific project without the distractions of the day-to-day operations and also bring our instinct to identify gaps and issues before they turn into costly or time consuming challenges.
As an independent Engine & Aircraft Technical Asset Management Company and CAMO, we don’t buy or sell assets, nor are we tied to any MRO or parts provider. This ensures our advice is truly impartial.
We know how challenging it can be for in-house teams to juggle daily operations with new and unexpected projects. With our Service without Distraction, our team focuses solely on your projects—uninterrupted by day-to-day demands. This dedicated approach maximises efficiency, drives cost savings, and significantly reduces risk, ensuring your goals are achieved without anything slipping through the cracks.
No two operations are alike. That’s why we offer flexible, scalable solutions that can be customised to fit your specific requirements. Whether you’re looking for full-service CAMO, transition management or targeted support for specific challenges, we’re here to ensure your assets —and your business, operate at peak efficiency.
