A 32-year-old advisory circular still used as the basis for showing compliance with in-flight icing protection rules is currently undergoing an “extensive” revision, and the FAA has published a draft version of it for comments. The objective of the revision, said the agency, is to provide a “uniform and modern” means of compliance with regulations for ice-protection requirements. The new circular, AC 20-73A, will also provide updated guidance relative to operating aircraft in icing conditions that may affect the aircraft’s airworthiness. Comments are due May 10. For more information call the FAA at (202) 267-9796.
