Essential Turbines Opens Expanded Arizona Facility, Tripling Capacity for Rolls-Royce Engine MRO

Essential Turbines (ETI), a Rolls-Royce Authorized Maintenance Repair & Overhaul Center (AMROC), announces the opening of its new Mesa, AZ, 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.
More than a facility expansion, the Mesa investment reflects ETI's operating principle of PEQ — Power. Expertise. Quality.
- Power: Tripling facility capacity to meet growing operator demand
- Expertise: Purpose-built infrastructure supporting enhanced talent and technical capabilities
- Quality: Modern, dedicated MRO environment reinforcing "Quality is Essential."
"After three years in a temporary space, we're making a permanent commitment to Arizona with a facility designed specifically for MRO excellence," says Gannon Gambeski, president and 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 and 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.
The company also announced the launch of its redesigned website at www.essentialturbines.com, featuring enhanced resources for operators, technical specifications, and streamlined customer support.
Visit Essential Turbines at Booth #B6204 during Verticon 2026 to learn more about the new Mesa facility and ET's global M250/RR300 engine MRO capabilities.
A formal grand opening event for the Mesa facility will be announced in the coming weeks.
