First Aviation Announces Expansion of S-70 Blackhawk Rotor Blade Capability

July 15, 2021 By kent

Piedmont Propulsion Systems, LLC, a wholly owned subsidiary of First Aviation Services Inc., announced today that it received an amendment to its Limited Airframe Rating with S-70 Capabilities from the FAA, enabling the company to perform all maintenance, repair and overhaul (“MRO”) services for S-70 / UH-60 Blackhawk main rotor blades.  This capability adds to Piedmont Propulsion’s existing approvals to perform MRO services for the Blackhawk main rotor hub and bifilar, and Van Horn Aviation 206/OH-58 Tail Rotor Blades and adds to the company’s many decades of experience in propeller blades and hub assemblies for all leading propeller product lines. Piedmont Propulsion’s sister company Aviation Blade Services, Inc. is the leading independent MRO facility supporting Blackhawk and other legacy Sikorsky rotor blades.

Paul Bolton, COO of First Aviation Services Inc., said, “Piedmont Propulsion’s FAA approval for the S-70 provides our Aviation Blade Services LLC subsidiary with both surge capacity and capability to perform on some of the largest rotor blade campaigns.  In addition, it provided an opportunity for Aviation Blade Services to demonstrate its third-party training and development program that we believe will provide substantial support to international operators who need to increase in country capability.”
