Notice of issuance of advisory circular.


This notice announces the issuance of Advisory Circular (AC) 23-16A, Powerplant Guide for Certification of Part 23 Airplanes and Airships. The intent of this AC is to standardize certification of powerplant installations in normal, utility, acrobatic, and commuter category airplanes and airships. It consolidates existing policy and certain other advisory circulars published prior to December 31, 2002, into a single document. The AC notes the guidance considered acceptable as a means of compliance with the Airship Design Criteria (ADC) requirements in document FAA-P-8110-2. The material in the advisory circular is intended as a reference for airplane and airship manufacturers, modifiers, and FAA engineers. The AC cancels AC 23-16.


Advisory Circular 23-16A was issued by the Manager of the Small Airplane Directorate on February 23, 2004.
