GM 21.A.165(c)(3) Definitions of engine type certification date and production date    

CAA ORS9 Decision No. 1

Volume II of Annex 16 to the Chicago Convention contains two different references to applicability dates:

1. ‘Date of manufacture for the first individual production model’ which refers to the engine type certification date; and

2. ‘Date of manufacture for the individual engine’ which refers to the production date of a specific engine serial number (date of Form 1).

The second reference is used in the application of engine NOx emissions production cut-off requirement which specifies a date after which all in-production engine models must meet a certain NOx emissions standard.

21.A.165(c)(3) includes the production requirements and refers to paragraphs (b) and (d) of Volume II, Part III, Chapter 2, paragraph 2.3 of Annex 16 to the Chicago Convention.
