When the wrong decision can cost millions, you need more than a consultant. You need experience, foresight, and a PARTNER you can count on.
TGIS Aviation provides independent technical and commercial expertise across the full engine lifecycle — from acquisition and maintenance to redelivery, valuation and lease review — ensuring our clients control costs, protect asset value and keep engines flying.


Since 2002 we’ve set the standard in aircraft and engine asset management and in 2024, we received our CAMO approvals from the CAA and overseas territories.

The value to you:
Independent, audited, CAA-approved assurance
Engine specialists who anticipate issues, not just react to them
Maintenance and records handled to CAMO standards with powerplant depth
Confidence for buyers and operators with a CAMO-approved stamp
When quality and value matter, trust the engine specialists at TGIS.
