Safran Larzac 04-C6 / C20 Engine Support
Purpose-Built Program Support
The Safran Larzac 04-C6 / C20 is a legacy low-bypass turbofan engine used on the Alpha Jet advanced trainer aircraft. While no longer in mass production, the platform remains in service worldwide for military and civilian training missions, requiring experienced, program-based maintenance support.
Essential Turbines Inc. has supported the Larzac program for more than a decade, providing specialized module-level overhaul and repair services under long-term, schedule-driven programs. This work differs from traditional commercial MRO and is performed as part of a structured maintenance ecosystem focused on reliability, consistency, and strict compliance.
