GM 21.A.15(e) and (f) Period of validity for the application for a type certificate (TC) or restricted type certificate (RTC) ED Decision 2019/018/R Point [21.A.15](#_DxCrossRefBm1649096854)(e) establishes a maximum period of validity for an application for a TC or an RTC. During this period, the type-certification basis, operational suitability data (OSD) certification basis, and the environmental protection requirements (hereinafter referred to as the ‘certification basis’), established and notified by EASA in accordance with points [21.B.80](#_DxCrossRefBm1649096853), [21.B.82](#_DxCrossRefBm1649096972) and [21.B.85](#_DxCrossRefBm1649096971), remain effective. However, the period of validity of the certification basis is limited so that the standards notified as part of the certification basis at the time of application do not become outdated. For various reasons (e.g. development, business, commercial, etc.), the applicant may not be able to complete the certification within the established time limit. In this case, the applicant has the following two options (see [21.A.15](#_DxCrossRefBm1649096854)(f)(1) and (2)): 1.       Submit a new application In this case, EASA establishes and notifies a new certification basis in accordance with points [21.B.80](#_DxCrossRefBm1649096853), [21.B.82](#_DxCrossRefBm1649096972) and [21.B.85](#_DxCrossRefBm1649096971), considering the standards that are available at the date of the new application. In accordance with point [21.A.15](#_DxCrossRefBm1649096854)(e), the new application has a maximum period of validity that is equal to the first one, corresponding to the product category. Beyond this period of validity, the applicant may need to choose again between the two options of either submitting a new application or applying for an extension of the initial application. 2.       Apply for an extension of the initial application In this case, the applicant proposes a ‘new target date’ to EASA for the issuance of the certificate, and selects a date that becomes the reference date for the establishment of the certification basis by EASA. For the purposes of this GM, the selected reference date is referred to as the ‘new effectivity date’ of the initial application. The ‘new effectivity date’ of the initial application may be any date in the past between the following time limits: — the ‘new target date’ for a TC proposed by the applicant minus the time limit used under [21.A.15](#_DxCrossRefBm1649096854)(e) (e.g. 5 years for large aeroplanes and large rotorcraft, 3 years for the other products); and — the date on which the applicant applies for the extension of the initial application. This calculation is visualised in Figure 1 below: ![Aviation.Bot AI suggestion, not from EASA source: [Image caption skipped for debugging]](/static/files/file_ocz75zUMmy4/image012.png) Figure 1 This ensures that the standards used to establish the certification basis are never older than the ones available at the start of the period of validity required by point [21.A.15](#_DxCrossRefBm1649096854)(e). If the applicant is not able to complete the product certification by the new target date, the applicant may choose again between the two options of either submitting a new application or applying for a new extension of the initial application. ##### GM 21.A.15(e) and (f) Period of validity for the application for a type certificate (TC) or restricted type certificate (RTC) *ED Decision 2019/018/R* Point [21.A.15](#_DxCrossRefBm485230344)(e) establishes a maximum period of validity for an application for a TC or an RTC.
