Common use of Procedures for Changes to a Type Clause in Contracts

Procedures for Changes to a Type. Certificate by the Type Certificate Holder and Changes to a Supplemental Type Certificate by the Supplemental Type Certificate Holder. (a) Changes to a type design that require a new TC or STC should be done in accordance with paragraphs 2.1 and 2.2, respectively. (b) All other changes to a type design by the ▇▇ ▇▇▇▇▇▇ or STC holder (on their own STC) should be done in accordance with the Post-Type Validation Principles (Appendix C of this document). These types of changes include: amended type certificates (derivative models), amendments to STCs; and those changes necessary for customer unique design features, product improvements and any other design changes, including revisions to approved manuals, made by the TC or STC holder, for whatever reason. (c) Irrespective of paragraph 3.2.1(b), any change in type design, minor or major, that may increase the noise levels of the aircraft or that may increase the fuel venting or exhaust emissions of an engine should be done in accordance with paragraph 3.2.6. (d) The FAA shall employ its procedures as defined in FAA Order 8110.52 to implement the Post-Type Validation Principles. EASA shall employ the procedures defined in the Appendix C of this document. (e) Where design changes are proposed, they shall be defined relative to the VA’s current definition of the approved type design. (f) For changes to a type design, except for acoustical or emissions changes, the VA’s date of application is the date application was made to the CA for the change. For design changes, the FAA shall develop its certification basis in accordance with 14 CFR §21.101, and §21.93(b) and (c). EASA shall develop its certification basis in accordance with EASA Part 21.101. FAA and EASA shall consult when changes to the certification basis justify using the TVP process to validate an amended TC. (g) In the case of an acoustical change, for FAA approval compliance must be shown with the applicable noise requirements of 14 CFR Part 36 in effect on the date of application to the FAA for approval of the design change. In the case of an emissions change, for FAA approval compliance must be shown with the applicable fuel venting and exhaust emissions requirements of 14 CFR Part 34 in effect on the date of application to the FAA for approval of the design change. (h) Design changes shall be classified as either Major or Minor in accordance with the CA’s criteria and procedures. Design changes classified as Major shall be further categorized as Level 1 Major and Level 2 Major in accordance with Post- Type Validation Principles (see Appendix C). (i) In discharging its responsibilities, the VA should seek to rely on the findings made and actions taken by the CA to the maximum extent possible. (j) The VA’s involvement shall be limited to activities, including design changes, affecting aircraft types registered, or due to be registered, in the VA’s jurisdiction and other products imported or planned to be imported, except where the TC or STC holder requests greater VA involvement (e.g., for design changes that could eventually be incorporated into the VA fleet) and this is agreed by the certificating and validating authorities. (k) The CA shall address relevant changes to the ICA during its design change approval. If changes to the ICA are required, these changes must be communicated to the VA.
