FAA approves Erickson's composite main rotor blades

Erickson Incorporated has announced FAA approval of its next-generation composite main rotor blades for S-64 and CH 54 rotorcraft, the company said.

After many years of manufacturing metal blades, Erickson has invested in the future of the S-64 rotorcraft by designing, certifying, and building composite main rotor blades. Erickson began the process of designing the new blades in 2008, working closely with the FAA and various industry partners.

In 2013 Erickson collaborated with Helicopter Transport Services (HTS), so the blades could be utilized on CH-54 rotorcraft as well. To maintain close control of blade manufacture, Erickson built a composite manufacturing facility from scratch in 2015. After thousands of hours of design, testing and analysis by Erickson´s engineers and partners, the new composite main rotor blades are now approved by the FAA for the S-64E with an initial life that will increase as fatigue testing continues.

Certification for the CH-54A is expected to follow quickly in the coming weeks, and certification for the S-64F and CH-54B is expected this summer.

Erickson is an operator, maintainer, and manufacturer of utility aircraft, specializing in defense and national security, manufacturing, Maintenance Repair and Overhaul (MRO), and Civil services.
