In 1991, CTI and Sikorsky entered into a rotor blade repair agreement to be licensed for the repairs of S-76, S-55, S-58, S-64 main and tail rotor blades.

On Tuesday, January 25 during Heli-Expo 2000 in Las Vegas, Michael Topa, CTI President and Michael Blake, Sikorsky VP Worldwide Customer Service, signed an amendment to the agreement to expand CTI repair capabilities to include repairs of main and tail rotor blades under the model designation S-61.

As Michael Topa says, "…the expansion of the Sikorsky product line reflects the strong relationship between the two companies [CTI & Sikorsky]. Sikorsky has chosen to increase customer support capability through CTI because of our proven history with Sikorsky products."
