21.A.165 Obligations of the holder

Compliance with the production organisation exposition (POE) is a prerequisite for obtaining and retaining a production organisation approval. The organisation should make the POE available to its personnel where necessary for the performance of their duties. A distribution list should therefore be established. Where the POE mainly refers to separate manuals or procedures, the distribution of the POE could be limited. The organisation should ensure that personnel have access to and are familiar with that part of the content of the POE or the referenced documents, which covers their activities. Monitoring of compliance with the POE is normally the responsibility of the quality assurance function.

APPLICABLE ENGINE EXHAUST EMISSIONS REQUIREMENTS This determination is made according to the data provided by the engine type-certificate holder. It should be noted that the competent authority has the possibility to grant exemptions from these requirements as noted in Chapter 2, paragraph 2.1.1 and Chapter 4, paragraph 4.1.1 of Part III of Volume II of Annex 16 to the Chicago Convention. When such an exemption is granted, the competent authority: takes into account the number of exempted engines that will be produced and their impact on the environment; considers imposing a time limit on the production of such engines; and issues an exemption document. ICAO Doc 9501 ‘Environmental Technical Manual’ Volume II provides guidance on the issuing of exemptions.

DEFINITIONS OF ENGINE TYPE CERTIFICATION DATE AND PRODUCTION DATE Volume II of Annex 16 to the Chicago Convention contains three different references to applicability dates:

1.the ‘date of manufacture for the first individual production model’, which refers to the date when the type certificate is issued for the engine type or model;

2.the ‘date of application for a type certificate’, which refers to the application date to the certificating authority of the State of Design of the engine type certification; and

3.the ‘date of manufacture for the individual engine’, which refers to the production date of a specific engine serial number (date of EASA Form 1). Point 1 refers to the date of the first engine EASA Form 1 issued after the completion of the engine production pass-off test. Point 3 refers to the date used in the application of engine emissions production cut-off requirement, on or after which all in-production engine models must meet a certain emissions standard. 21.A.165(c)(3) includes the applicable production requirements for aircraft engine emissions. ICAO Doc 9501 ‘Environmental Technical Manual’ Volume II provides guidance on these applicability dates.

APPLICABLE AEROPLANE CO2 EMISSIONS REQUIREMENTS This determination is made according to the data provided by the aeroplane type-certificate holder. This data should allow the determination of whether the aeroplane complies with the CO2 emissions applicability requirements in Chapter 2, paragraph 2.1.1 of Part II of Volume III of Annex 16 to the Chicago Convention. It should be noted that the competent authority has the possibility to grant exemptions as noted in Chapter 1, paragraph 1.11 and Chapter 2, paragraph 2.1.3 of Part II of Volume III of Annex 16 to the Chicago Convention. When such an exemption is granted, the competent authority: takes into account the number of exempted aeroplanes that will be produced and their impact on the environment; and issues an exemption document. ICAO Doc 9501 ‘Environmental Technical Manual’ Volume III provides guidance on the issuing of exemptions.
