Essential Turbines, a Rolls-Royce Authorized Maintenance Repair & Overhaul Center, announced the opening of its new Mesa, Arizona facility—a purpose-built MRO location that triples the company’s U.S. capacity for M250 and RR300 turboshaft engines.
The modern facility replaces ETI’s temporary Phoenix-area location and provides dedicated infrastructure for engine overhaul, test cell operations, and component repair. The expansion enables ETI to enhance both critical capabilities and technical expertise while delivering faster turnaround times to U.S. and Southwest regional operators.
“After three years in a temporary space, we’re making a permanent commitment to Arizona with a facility designed specifically for MRO excellence,” said Gannon Gambeski, President & CEO of Essential Turbines. “This purpose-built location gives our team the modern infrastructure and expanded capacity to deliver the quality and responsiveness Essential Turbines is known for.”
The Mesa expansion is part of ETI’s strategic growth plan to strengthen its North American MRO network and support the global install base of 16,000+ M250 and rapidly growing RR300 engines in service. The facility serves operators across emergency medical services, government, utility, oil & gas, and commercial helicopter sectors.
Essential Turbines operates as a member of the Rolls-Royce FIRST Network, providing authorized MRO services from facilities in Montreal, Vancouver, Mesa, and Malta.
Essential Turbines also announced the launch of its redesigned website, featuring enhanced resources for operators, technical specifications, and streamlined customer support.
