Design Approval Procedures for U Clause Samples
The Design Approval Procedures for U clause establishes the process by which design submissions are reviewed and approved by the party identified as "U." Typically, this clause outlines the steps for submitting design documents, the timeframe within which U must respond, and the criteria or standards that must be met for approval. For example, it may require U to provide written feedback or approval within a set number of days, and specify what happens if U fails to respond. The core function of this clause is to ensure a clear, structured process for design approvals, reducing delays and misunderstandings between parties during project development.

3.4.1 Application Process for an FAA Letter of TSO Design Approval
3.4.1.1 An application for an FAA Letter of TSO Design Approval from an applicant in New Zealand may only be submitted for articles that have been approved by the CAA through a CAA TSO Authorization and of a kind for which a minimum performance standard has been published in an FAA TSO.
3.4.1.2 The applicant must forward the application package and include all applicable technical data listed in paragraph 3.4.1.3 to the CAA.
3.4.1.3 The CAA should ensure that the application package contains the following information:

3.4.1.6 When the CAA receives an application for an FAA Letter of TSO Design Approval to a TSO performance standard to which the CAA has not previously made compliance findings, the CAA will contact the applicable FAA office indicated in Appendix A for the latest FAA technical policy and procedures related to the FAA TSO performance standard. The FAA may elect to conduct an additional technical evaluation of the CAA’s understanding of the specific TSO requirements.
