Advisory Circular (AC) 23-17B, Systems and Equipment Guide for 
Certification of Part 23 Airplanes and Airships

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of issuance of advisory circular.

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

SUMMARY: This advisory circular (AC) sets forth an acceptable means, 
but not the only means, of showing compliance with Title 14 Code of 
Federal Regulations (14 CFR), part 23, for the certification of systems 
and equipment in normal, utility, acrobatic, and commuter category 
airplanes and airships. The policy in this AC is considered applicable 
for airship projects; however, the certifying office should only use 
specific applicability and requirements if they are determined to be 
reasonable, applicable and relevant to the airship project. This AC 
applies to Subpart D from Sec.  23.671 and Subpart F. This AC both 
consolidates existing policy documents, and certain ACs that cover 
specific paragraphs of the regulations, into a single document and adds 
new guidance. This revision has added preamble material, in italics, 
under the applicable rule and amendment level. Material in this AC is 
neither mandatory nor regulatory in nature and does not constitute a 
regulation.
    The draft AC was issued for Public Comment on September 29, 2004 
(69 FR 58213). No comments were received.

DATES: Advisory Circular (AC) 23-22 was issued by the Manager, Small 
Airplane Directorate on April 12, 2005.
