Discussion

    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 the 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, as necessary, to identify acceptable means of compliance. The 
information contained in the AC sets forth acceptable means, but not 
the sole means, by which compliance may be shown with the requirements 
of Part 34.
    Pursuant to the Clean Air Act, Sections 231 and 232, Part 34 must 
conform to 40 CFR part 87 as issued by the United States Environmental 
Protection Agency. Potential users of this proposed AC, as well as Part 
34, should be alert to any changes to 40 CFR part 87 that have not yet 
been included in either Part 34 or this AC. In such instances the 
requirements of 40 CFR Part 87 are considered controlling.
    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 read these sections.

    Issued in Washington, DC on September 22, 1998.

Director of Environment and Energy.
