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. During the past two years, Sikorsky has transitioned the Final Assembly of both the S76 and S92 helicopter to Keystone, as well as all new aircraft completions. In 2008, Keystone added a new state-of-the-art Flight and Delivery Hangar to complement its world-class Heliplex in Pennsylvania near the Chester County Airport.

In addition to the new aircraft final assembly and completions services it performs, Keystone Helicopter operates the premier full-service maintenance and customization center in the northeast. U.S. Keystone is factory-authorized by every major rotorcraft OEM and is an authorized dealer for virtually every major avionics manufacturer. During 2008, Keystone invested $250,000 to upgrade its facilities to offer the same world-class level of aftermarket service it offers to new helicopter customers.

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 Helicopter also offers complete repair and overhaul of Rolls-Royce 250 Series engines, as well as repair services for many engine accessories. This year, Keystone was also awarded Production Certificate 121NE by the FAA, signifying it met the most stringent quality standards and demonstrated fully compliant production capability required for production of the S76 helicopter.


Keystone Helicopter’s engineering services division provides comprehensive technical and certification support for both rotorcraft and fixed wing owners and operators. Newly awarded one of the first ODA designations by FAA, it has the ability to provide timely support to its customers. 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 Keystone Helicopters, we demand of ourselves the highest levels of quality, service and value," said 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."
