Airworthiness Standards
Aircraft Emissions
2nd Edition
November 1991
Interpretation Provision for Part V Standards
In these Standards:
(a) The passages giving the Minister powers to determine, approve or authorise something without stating criteria for the use of such powers are to be interpreted as requiring that the powers be used in consideration of two factors only: the airworthiness of the aircraft that is the subject of the determination, approval or authorisation, or on which an aeronautical product that is the subject of the determination, approval or authorisation is to be installed, and the aircraft’s level of safety; and
(b) The word "approved", when used without any indication of a method of approval, is to be interpreted as referring to an approval granted under the Aeronautics Act.

Preamble
Subchapter A
AIRCRAFT NOISE
516.5 Noise Emission Standards
516.7 Noise Evaluation Methods
AIRCRAFT ENGINE EMISSIONS
516.107 Aircraft Engine Emission Standards
516.109 Aircraft Engine Emission Evaluation Methods
Second Edition
Effective: 1 November 1991
The first edition of Chapter 516, effective Nov. 30, 1985, contained aircraft noise standards, based on the International Standards and Recommended Practices of Annex 16, Volume I to the Convention on International Civil Aviation, which were incorporated by reference. The chapter was subsequently amended in 1987 and 1988. While the title and the requirements of the first edition are maintained unchanged in Subchapter A of this second edition, the presentation and the wording are changed for consistency with the new Subchapter B.
In 1986, at the time of the publication of Chapter 516, the engine emission standards of Annex 16, Volume II were not adopted due to controversial interpretations of the Aeronautics Act. The Department of Justice has reviewed the issue and has concluded that, under the provisions of paragraph 4.9 (b) of theAeronautics Act, the Department of Transport has the power to regulate aircraft engine emissions. Accordingly, following consultation with the Canadian aviation industry and the Department of Environment, the Department of Transport has adopted the aircraft engine emissions standards of Volume II of Annex 16 to the Convention on International Civil Aviation, First edition, 1981, published by the International Civil Aviation Organization (ICAO). These standards are published in the new Subchapter B.
The adoption of the standards of Annex 16, Volume II has required significant editorial changes to the first edition. Therefore, Chapter 516 is reissued in its entirety, and its title is changed to "Aircraft Emissions". In the Canadian context, environmental protection is the responsibility of the Department of Environment and, while the standards of this chapter will have an ultimate environmental effect, the authorization in paragraph 4.9 (b) of the Aeronautics Act is to regulate the design of aeronautical products. Therefore, the title "Aircraft Emissions" has been found more appropriate than "Environmental Protection", which is the title given to ICAO Annex 16.
Change 516 (2nd Ed.)-1
Effective: 11 November 1993
This change incorporates by reference, Amendment 4 and Amendment 2 respectively to Volume I "Aircraft Noise", and Volume II "Aircraft Engine Emissions" of Annex 16 to the Convention on International Civil Aviation. These amendments arise from the recommendations of the second meeting on the Committee on Aviation Environmental Protection (CAEP/2) held in December, 1991.
Among other changes, Amendment 4 to Volume I introduces the new Chapter 11 and associated Appendix 7 containing a simplified noise certification scheme for light helicopters.
Change 516 ( 2nd Edition)-2
Effective: 8 February 1998
The publication and release of this Change 2 to the 2nd Edition, follows the completion of CARAC NPA 97-451 process, dated 17 November 1997.
This change incorporates by reference, Amendment 5 and Amendment 3 respectively to Volume I "Aircraft Noise", and Volume II "Aircraft Engine Emissions" of Annex 16 to the Convention on International Civil Aviation. These amendments arouse from the recommendations of the third meeting on the Committee on Aviation Environmental Protection (CAEP/3) held in December, 1995.
For consistency with the new Canadian Aviation Regulations, references to Air Regulation 214, have been replaced with references to the Canadian Aviation Regulations, Part V, Subpart 11. Also the term "type approval" has been replaced with "type certificate".
Amendment 5 to Volume I incorporates:
a. simplification and clarification of the noise certification schemes in Chapter 3 for propeller-driven aircraft;
b. harmonisation of the helicopter Standards in Chapters 8 and 11 with national codes; and
c. alignment of the take-off mass in Chapter 10 with airworthiness limits.
Amendment 3 to Volume II incorporates:
amendment of the criteria on calibration and test gases in Appendices 3 and 5.
