During the past 50 years, Keystone Helicopter has gained a reputation as an industry leader in quality rotor­craft services. Today, the company employs more than 900 people at one of the finest and fastest-growing facilities in the country. In late 2005, Keystone was purchased by Sikorsky Aircraft Corporation—its largest customer. During the next two years, Sikorsky transitioned the final assembly of both the S-76 and S-92 helicopter to Keystone, as well as all new air­craft completions. In 2008, Sikorsky added a new state-of-the-art paint facility, and in 2009 a new world-class flight and delivery hangar. Also during 2009, Sikorsky re-branded the new aircraft operation as Sikorsky Global Helicopters.

In addition to the new aircraft final assembly and completions services it performs, the world-recognized Keystone Helicopter brand has been retained for aftermarket services. Keystone operates the premier full-service maintenance and customization center in the northeast U.S. The company is factory-authorized by every major rotorcraft OEM and avionics manufacturer, as well as Rolls-Royce for engine manufacturers.

As an FAA-and EASA-certified repair station, Keystone Helicopter provides complete rotorcraft services, including airframe maintenance, avionics integration and installation, component repair and overhaul, engineering, custom fabrication, machining, paint and refinishing, “green aircraft” completions and complete interior refurbishments. Keystone also offers complete repair and overhaul of Rolls-Royce 250 series engines, as well as repair services for many engine accessories. This year, Keystone also successfully petitioned FAA for the addition of the S-92 to its Production Certificate 121NE, signifying it met the most stringent quality standards.


Keystone Helicopter’s engineering services division provides comprehensive technical and certification support for both rotorcraft and fixed-wing owners and operators. Keystone was awarded one of the first ODA designations by FAA. Its engineers have issued hundreds of STCs, with expertise in structures, avion­ics, systems engineering, flight critical software, and flight-testing. Overall, Key­stone offers a wide range of certification services, including STC, TSO, PMA and FAA/DER-approved data for 337s.

“The bottom line: At Sikorsky Global Helicopters, and Keystone Helicop­ter, we demand of ourselves the highest lev­els of quality, service and value,” says Keystone President David Ford. “With the new backing of a world-class OEM, a dedicated and experienced workforce, and new enhanced facilities, we are the new world-class standard in rotorcraft services.”
