Naasco Northeast (Booth No. 4551), provider of repair and overhaul services for starter-generators and other engine components, marks 25 years of attendance at Heli-Expo this year with a completely redesigned booth. The updated display forms the backdrop for Naasco’s presentation of its newest capabilities in starter-generator repair and overhaul and parts made under FAA Parts Manufacturer Approval (PMA) regulations. This includes the company’s ETR-20 and ETR-25 Mercury Mod improvement program and its Sil-Met repair technology that can transform consumable parts (primarily in power relays) into repairable parts, according to Naasco. The company’s proprietary repairs are approved for engines used in Agusta, Bell, Eurocopter, MD, Schweizer and Sikorsky rotorcraft. Shirley, N.Y.-based Naasco also manufactures numerous PMA replacement parts for starter generators, relays, actuators and pumps.
