Additional Help

1. The letter of application should be of sufficient detail to allow the GACA to make the decision to support the project. The content must indicate the following:

a) Design Approval holder/applicant name and normal place of business;

b) Description of the design change; including an explanation of the purpose of the change, the pre-modification and post-modification configuration(s) of the product, schematics/pictures, and any other detailed features and boundaries of the physical change (this may be supplemented by drawings or outlines of the design, as well as the identification of the changes in areas of the product that are functionally affected by the change, and the identification of any changes to maintenance and operational manuals;

c) Aircraft type, serial number and KSA registration marks;

d) Organization that will be responsible for performing the alteration on the aircraft;

e) Location of the aircraft during the STC project;

f) Starting date and duration of the STC project;

g) Whether flight testing will be conducted;

h) Concurrent activities on the aircraft;

i) Request for GACA concurrence for the use an aircraft registered in the KSA as a prototype;

j) Request for GACA concurrence for the use of GACA Recognized Foreign NAA Designees if applicable.

k) Request for any specific information required in support of the GACA Recognized Foreign NAA undue burden process (if applicable);

l) Invitation for GACA participation; and

m) Identification of the Certification Project Manager(s), including their contact details.
2. GACA accepts all design changes (including STC) introduced by the holder of the TC. This is considered to be an automatic acceptance. There is no need to obtain GACA concurrence for the embodiment of such design change into Saudi registered aircraft.

3. The design change criteria stated in this section also apply to repair designs.

4. It is a GACA philosophy regarding design changes issued by foreign aviation authority other than GACA Recognized Foreign NAA and to be performed on an aircraft registered in the KSA is to minimize its involvement in the certification process. However, because of its responsibility as the State of registry for the aircraft, the GACA must understand the nature of the design change and might therefore need to participate in some of the activities of certification process to the extent required to secure that understanding on a case-by-case basis. This could include participation in meetings, requests for clarifications following review of design or certification documents, and participation in certification inspections and tests as an observer.
5. No approval has been or will be issued by GACA Recognized Foreign NAA.
