At TGIS Aviation, we support all major commercial aircraft engine types – working across Rolls-Royce, General Electric, Pratt & Whitney, CFM International, Engine Alliance, and IAE fleets.
From high-utilisation narrowbody workhorses to complex widebody and next-generation engines, we help operators, lessors, and investors truly understand their engines – so they can make smarter, safer, and more cost-effective decisions at every stage of the lifecycle.
Our role is often most valuable when the stakes are highest: during shop visits, lease returns, redeliveries, acquisitions, and cost-critical maintenance events. As an independent, engine-focused specialist, we don’t sell parts and we don’t align to MROs – allowing us to challenge scope, protect cost, and safeguard asset value with confidence.
Explore the engine types we support below, including where we see the greatest risks — and how TGIS supports clients to manage them calmly and effectively.
