SUPPLEMENTARY INFORMATION: Advisory Circular (AC) 34-1, Fuel Venting 
and Exhaust Emission Requirements for Turbine Engine Powered Airplanes, 
has been written to provide section-by-section guidance on 14 CFR Part 
34. The AC is intended to provide a better understanding of the 
provisions of the Part 34, and to facilitate standardized 
implementation of Part 34 throughout the aviation industry. The AC 
contains information concerning the standards and requirements for 
aircraft fuel venting and engine emission certification, and presents 
explanatory information and guidance. The information contained in the 
AC also sets forth acceptable means, but not the sole means, by which 
compliance may be shown with the requirements of Part 34.
    In addition to the section-by-section explanations, the AC includes 
three chapters that explain specific appendices from the International 
Civil Aviation Organization (ICAO), Annex 16, Volume II, Aircraft 
Engine Emissions. Since Annex 16 is specifically referenced in Part 34, 
these chapters are included to make the AC a more complete reference 
source.
    The ICAO appendices deal with detailed technical issues regarding 
instrumentation and measurement techniques and, as such, are relatively 
complex. Thus, they have been kept distinct from the rest of the AC as 
separate chapters. Typically, only those readers who are interested in 
specific equations and/or details regarding measurement techniques will 
need to refer to these sections.
    A Notice of Availability of the Draft AC 34-1 was issued in the 
Federal Register, dated September 29, 1998, Volume 63, Number 188, Page 
51990. Comments received on the Draft AC have been considered and 
revisions have been incorporated into AC 34-1. These revisions include 
comments received during a workshop held with the FAA field personnel 
and Designated Engineering Representatives, and supportive comments, 
primarily of an editorial nature, from Transport Canada, the United 
Kingdom Civil Aviation Authority, and the French Director General of 
Civil Aviation.
    AC 34-1 continues to be developed by the FAA, including 
coordination with the European Joint Aviation Authorities (JAA) and 
other international authorities. The FAA expects to publish revisions 
periodically.

    Issued in Washington, DC on July 17, 2000.
