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.
