Procedures for Changes to a Type Clause Samples
The "Procedures for Changes to a Type" clause defines the process by which modifications to a specific type—such as a product, service, or contractual category—can be proposed, reviewed, and implemented within an agreement. Typically, this clause outlines the steps required for one party to request a change, the documentation or notice that must be provided, and any approvals or consents needed from the other party. For example, if a supplier wishes to update the specifications of a product type delivered under contract, this clause would dictate how that change is formally submitted and agreed upon. Its core practical function is to ensure that any alterations to key types are managed transparently and systematically, reducing the risk of misunderstandings or disputes over unauthorized changes.
Procedures for Changes to a Type. Design (TC/STC) Affecting Noise and Emissions.
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 this section and 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 affecting noise, fuel venting, or exhaust emissions will be evaluated according to the procedures of paragraph 3.2.10.
(d) Any change to an Approved Manual not associated with a Level 1 Major change shall be evaluated using the procedures of paragraph 3.2.11.
(e) Where design changes are proposed, they shall be defined relative to the VA’s current definition of the approved type design.
(f) Design changes shall be classified in accordance with Post-Type Validation Principles (see Appendix C, section III, 8. Design Change Approval Process).
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 Leve...
