14 C.F.R. Subpart H—Test Procedures for Engine Smoke Emissions (Aircraft Gas Turbine Engines)
Title 14 - Aeronautics and Space
Except as provided under §34.5, the procedures described in this subpart shall constitute the test program to be used to determine the conformity of new and in-use gas turbine engines with the applicable standards set forth in this part. The test is essentially the same as that described in §§34.60–34.62, except that the test is designed to determine the smoke emission level at various operating points representative of engine usage in aircraft. Other smoke measurement systems may be used if shown to yield equivalent results and if approved in advance by the Administrator or the Administrator of the EPA. Fuel having specifications as provided in §34.61 shall be used in smoke emission testing. The system and procedures for sampling and measurement of smoke emissions shall be as specified in Appendix 2 to ICAO Annex 16, Volume II, Environmental Protection, Aircraft Engine Emissions, Second Edition, July 1993, effective July 26, 1993. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. This document can be obtained from, and copies may be reviewed at, the respective addresses listed in §34.64. [Doc. No. FAA–1999–5018, 64 FR 5560, Feb. 3, 1999; Amdt. 34–3, 64 FR 60336, Nov. 5, 1999]

PART 34—FUEL VENTING AND EXHAUST EMISSION REQUIREMENTS FOR TURBINE ENGINE POWERED AIRPLANES
Subpart H—Test Procedures for Engine Smoke Emissions (Aircraft Gas Turbine Engines)
§ 34.80 Introduction.
§ 34.81 Fuel specifications.
§ 34.82 Sampling and analytical procedures for measuring smoke exhaust emissions.
§§ 34.83-34.88 [Reserved]
§ 34.89 Compliance with smoke emission standards.
Compliance with each smoke emission standard shall be determined by comparing the plot of SN as a function of power setting with the applicable emission standard under this part. The SN at every power setting must be such that there is a high degree of confidence that the standard will not be exceeded by any engine of the model being tested. An acceptable alternative to testing every engine is described in Appendix 6 to ICAO Annex 16, Environmental Protection, Volume II, Aircraft Engine Emissions, Second Edition, July 1993, effective July 26, 1993. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. This document can be obtained from the address listed in §34.64. Other methods of demonstrating compliance may be approved by the Administrator with the concurrence of the Administrator of the EPA.
