On Tuesday, August 18, 2004, the FAA published Notice of issuance of advisory circular for “AC 23.1419-2C, Certification of Part 23 Airplanes for Flight in Icing Conditions” in the Federal Register. This AC “applies to the approval of airplane ice protection systems for operating in the icing environment defined by Part 25, Appendix C”. It provides acceptable means for complying with the ice protection requirements of FAR Part 23. Applicant’s for type certificates, supplemental type certificates or amendments to existing type certificates will want to reference this AC when seeking approval under FAR 23.1419.
The AC does not provide the only means of compliance and, as with all AC’s, is not mandatory and is not a regulation. A copy of the AC is available here.
