Large airplanes certificated under EASA CS-25 are the subject of a notice of proposed amendment (NPA) intended to mitigate the risks of incidents and accidents caused by airframe ground icing contamination or inadequate de-icing/anti-icing operations. The certification specifications for large airplanes would be amended in the following areas: design requirements for take-off with a determined level of contamination of the aerodynamic surfaces; and criteria for the testing and selection of de-icing/anti-icing fluids. This NPA does not propose the mandate of on-board systems to alert the crew of potential contamination of the wing. Within the NPA it is proposed instead to continue and reinforce safety promotion actions to raise awareness of the community on this issue. Comments on the NPA are due by October 25, 2022.
