23.1419-2A, and request for comments.

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

SUMMARY: This notice announces the availability of and request for 
comments on a proposed AC, which provides information and guidance 
concerning certification of part 23 airplanes for flight in icing 
conditions.

DATES: Comments must be received on or before March 3, 1998.

ADDRESSES: Send all comments on the proposed AC to: Federal Aviation 
Administration, Small Airplane Directorate, Aircraft Certification 
Service, Standards Office (ACE-110), 601 East 12th Street, Kansas City, 
Missouri 64106.

FOR FURTHER INFORMATION CONTACT:
Ervin Dvorak, Standards Office (ACE-111), Small Airplane Directorate,

COMMENTS INVITED: We invite interested parties to submit comments on

BACKGROUND: This Advisory Circular, AC 23.1419-2A, Certification of 
Part 23 Airplanes for Flight in Icing Conditions, sets forth an 
acceptable means, but not the only means of demonstrating compliance 
with the ice protection requirements in 14 CFR part 23. The 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. This AC will cancel AC 
23.1419-2, Certification of Part 23 Airplanes for Flight in Icing 
Conditions, dated January 3, 1992. This AC revises AC 23.1419-2 for 
icing certification for part 23 airplanes to address the following NTSB 
Recommendations: A-91-90, A-92-64, and A-92-86, the later amendments 
(23-41, 23-42, 23-43, 23-45, and 23-49) in part 23, and it provides 
information regarding tail plane icing.
    The FAA Inflight Aircraft Icing Plan has tasks to improve the 
regulations and guidance related to certification of airplanes for 
operation in icing conditions defined by Appendix C and,

possibly, including envelopes supplementing those currently in Appendix 
C. These issues will be considered on the next revision of the AC. In 
addition, the FAA and the Joint Aviation Authorities (JAA) are 
harmonizing the performance and handling qualities of part 25. The 
Aviation Rulemaking Advisory Committee (ARAC) Flight Test Harmonization 
Working Group will complete the harmonization project to standardize 
performance, handling requirements, and additional guidance material 
for certification of part 25/Joint Aviation Requirements 25 (JAR 25) 
airplanes to safely operate in the icing conditions of Appendix C. 
These performance and handling qualities will be considered in the next 
revision to this AC, and to the second revision to AC 23-8A, Flight 
Test Guide for Certification of Part 23 Airplanes.

    Issued in Kansas City, Missouri, December 16, 1997.
Michael Gallagher,
Manager, Small Airplane Directorate Aircraft Certification Service.
