Faster Turnaround
Essential Turbines, an authorized maintenance and overhaul center for Rolls-Royce engines, has opened a new facility in Mesa. The company previously operated from a temporary site in Metro Phoenix. Essential Turbines is also part of the engine manufacturer’s FIRST (Fully Integrated Rolls-Royce Support Team) network, a global system of approved maintenance providers.
The new Mesa facility significantly expands the company’s capabilities. Essential Turbines has tripled its capacity to service the M250 and RR300 engines, allowing the company to handle a higher volume of work and reduce turnaround times for operators across the United States, particularly in the Southwest.
Purpose-built infrastructure at the site includes dedicated areas for engine overhaul, test cell operations, and component repair. These upgrades will help streamline maintenance processes, improve efficiency, and ensure faster, high-quality service for customers operating helicopters and other aircraft powered by Rolls-Royce engines.
