U.S. Federal Aviation Regulation FAR 25.581 mandates that every aircraft “aircraft must be protected against catastrophic effects of lightning."
Aircraft certification and flight safety authorities around the world require that aircraft structures and systems that are critical or essential to the safe flight of an aircraft be protected from significant lightning-induced damage or upset. These requirements are fulfilled through a certification plan that details the lightning protection engineering and shows — through verification testing — that the engineering meets all applicable standards and regulations.
NTS and Lightning Technologies, Inc. (LTI) provide lightning protection engineering, certification plan preparation and verification testing services to airframe and aerospace systems manufacturers around the world. With a lead role in major commercial and military design programs, our engineers take a systemwide approach to assuring that lightning protection is compatible with space and weight limitations, electromagnetic compatibility and electromagnetic pulse. Our experience includes traditional designs, all-composite and fly-by-wire aircraft, as well as avionic upgrades and engine modifications.
Lightning can affect avionics systems in two ways: directly, causing physical damage due to heat or shock, and indirectly, as a result of earth voltage rises occurring in the aftermath of a strike. Proper testing to ensure lightning strike protection must take into account both factors. At NTS, we are fully equipped to provide comprehensive testing of both factors, ensuring you are compliant with DO-160 Section 22, MIL-STD 461/462 and other relevant standards.
With our 2011 acquisition of Lightning Technologies, Inc., NTS has positioned itself as a leader in the field of aircraft lightning protection. In addition to the Pittsfield facility, we maintain multiple labs around the country to conveniently serve aerospace and military contractors from coast to coast.
