This service allows the beneficiaries to apply for GACA acceptance of Minor Design Change under the provisions of GACAR Part 21 Subpart C “Changes to Type Certificates” when a Minor Change Approval is issued by GACA Recognized Foreign NAA (GACAR §21.63 (d)(i)). The design change criteria stated in §21.63 also apply to repair designs.

1. GACA Type Certificate Acceptance (TCA)

2. Familiarity with the Aircraft Certification process.

Interim Measures; GACA will review and assess the required documents. GACA will check if any specific additional airworthiness requirements are applicable to the proposed design change and may choose to carry out a compliance inspection of the modified aircraft depending on the outcome of the assessment. More details will be provided by the GACA Certification Project Manager (CPM) assigned to this project. Once found satisfactory, GACA Acceptance letter will be issued.

Approval privileges document (FAA ACO Minor Change Agreement, EASA Design Organization Approval, or equivalent) (if applicable).
Company Manual (Handbook, Procedures, Work Instructions) related to the intended certification activities.
Design change classification document issued in accordance with FAR §21.93 (a)&(b) or EASA 21A.91.
Letter of application addressed to General Manager of Airworthiness. See additional help.
Minor Change Approval issued by GACA Recognized Foreign National Aviation Authorities (For Existing Approved Data).
Owner/Operator acknowledgement for the proposed design change.

1. Minor Change Approval (issued by GACA Recognized Foreign National Aviation Authorities). If the Minor Change Approval is not issued yet, the procedure for Ongoing Certification Project will be used.

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 design change on the aircraft;

e) Location of the aircraft during the design change project;

f) Starting date and duration of the design change project;

g) Whether flight testing will be conducted;

h) Concurrent activities on the aircraft;

i) Request for GACA concurrence for the use of 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 coordinates.

2. It is a GACA philosophy regarding design changes issued by 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.

Application : The applicant must submit all relevant documents as requested by the General Authority of Civil Aviation.
Review : GACA will review the documents submitted by the applicant and verify if it complies with the regulations and can ask the applicant to update his application.
Issue : GACA will only issue the Certificate/Permit when the E-Service process allows it and GACA is completely satisfied that all regulatory requirements have been adequately addressed.
