EASA: Wind Shear Rule Should Stay As Is

Despite an International Civil Aviation Organization (ICAO) recommendation for wind shear warning systems on larger aircraft, the European Aviation Safety Agency has decided against mandating the systems. EASA this month released a notice of proposed amendment (NPA) that concludes, based on a cost-safety-benefit assessment, “no regulatory action is needed to require wind shear equipment on European-registered aircraft.” The NPA was in response to the ICAO recommendation that all turbine airplanes in excess of 12,500 pounds mtow or authorized to carry more than nine passengers be equipped with a wind shear warning system. EASA said that while such a requirement would “provide a measure of protection for all new airplanes; the cost cannot be justified by the safety benefit.” The preferred option would be to do nothing, the agency said. There is no economic impact from this option, EASA said, and although wind shear encounters are expected to increase over the next 10 years due to the growth in aircraft movements, “this do-nothing option is not considered to result in a decrease in safety.” Comments on the NPA are due Feb. 15, 2017. A final rule is expected to be published by the fourth quarter of 2018.
