ED Decision 2022/001/R

Regular update of AMC-20 — AMC-20 Amendment 23

The objective of this Decision is to provide state-of-the-art means for showing compliance with the applicable airworthiness requirements with regard to the following:

  • EASA AMC 20-136 Aircraft electrical and electronic system lightning protection; 
  • EASA AMC 20-158 Aircraft electrical and electronic system high-intensity radiated fields (HIRF) protection; and
  • EASA AMC 20-193 Use of multi-core processors (MCPs).

These amendments to AMC-20 are expected to facilitate the certification process while maintaining an adequate level of safety. They will also improve harmonisation with the equivalent FAA ACs.
Overall, they would have an economic and safety benefit, without any environmental or social impacts.
