Advisory Circular (AC) 23.1419-2C, Certification of Part 23 
Airplanes for Flight in Icing Conditions

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of issuance of advisory circular.

-----------------------------------------------------------------------

SUMMARY: This notice announces the issuance of Advisory Circular (AC) 
23.1419-2C. This AC sets forth an acceptable means, but not the only 
means, of demonstrating compliance with the ice protection requirements 
in Title 14 of the Code of Federal Regulations (14 CFR) Part 23. The 
Federal Aviation Administration (FAA) will consider other methods of 
demonstrating compliance that an applicant may elect to present. This 
material is neither mandatory nor regulatory in nature and does not 
constitute a regulation. The guidance provided here applies to the 
approval of airplane ice protection systems for operating in the icing 
environment defined by Part 25, Appendix C. The guidance should be 
applied to new Type Certificates (TCs), Supplemental Type Certificates 
(STCs), and amendments to existing TCs for airplanes under part 3 of 
the Civil Aviation Regulations (CAR) and Part 23, for which approval 
under the provisions of Sec.  23.1419 is desired. The proposed guidance 
is added for fluid ice protection systems, primary ice detection 
systems, ice protection of air data systems, failure analyses of ice 
protection systems, and modifications to airplanes certificated for 
flight in icing. The format is also changed to improve readability of 
the document.
    The draft policy statement was issued for Public Comment on April 
19, 2004 (69 FR 7846). When possible, comments received were used to 
modify the draft policy.

Airplane Directorate on July 21, 2004.
