Airworthiness Standards; Electrical and Electronic System Lightning Protection
The Federal Aviation Administration (FAA) proposes to amend the lightning protection airworthiness standards by establishing new lightning protection regulations for electrical and electronic systems installed on aircraft certificated under parts 23, 27, and 29, and revising lightning protection regulations for electrical and electronic systems installed on airplanes certificated under part 25. The proposed rulemaking would establish two levels of lightning protection for aircraft systems based on consequences of system function failure: Catastrophic consequences which would prevent continued safe flight and landing and hazardous or major consequences which would reduce the capability of the aircraft or the ability of the flightcrew to respond to an adverse operating condition. The proposed rulemaking would also establish lightning protection for aircraft systems according to the aircraft's potential for lightning exposure. Compliance with the new requirements would be based on demonstration of effective lightning protection for electrical and electronic systems. The proposed airworthiness standards would establish consistent lightning protection requirements for electrical and ele
