The McNally Group performs Maintenance, Repair and Overhaul (MRO) services for both Defense and Commercial Aerospace customers and platforms.

Our support for the world's commercial air carriers, private aviation and the military ensures that our customers' aircraft windows and avionics are maintained and in a constant state of readiness. The McNally Group's FAA-certified facilities have full diagnostic capabilities and include state-of-the art window and avionics shops and the world's largest in-house exchange pool of new, rebuilt and overhauled passenger and cockpit windows. The McNally Group maintains over two decades of experience in avionics and instrument repairs, providing warranty services and product line support for leading aerospace companies including Boeing, Airbus and Bendix King/Honeywell.

On the military side, our service entails restoring our own proprietary products and customer products to "like new" condition. We perform overhaul and repair for our rotary gear pumps, valve assemblies and Phalanx coolant pumps. We perform complete overhaul services for the Mk6 ammunition hoist, some of which have been at sea for 20 years. In fact, the United States Navy utilizes our facility as a Designated Depot for the Mk6 Hoist.
