قبول تغيير التصميم (تغيير رئيسي في STC إلى STC)

Pre-Requisites

1. GACA Type Certificate Acceptance (TCA)
2. Familiarity with the STC Certification Process

Required Documents

• Approval privileges document (FAA ACO Minor Change Agreement, EASA Design Organization Approval, or equivalent) (if applicable)
• Certification Plan
• Company Manual (Handbook, Procedures, Work Instructions) related to the intended certification activities
• Compliance Checklist
• Continued Airworthiness Data:
  • Instructions for Continued Airworthiness
  • Airworthiness Limitations
  • Electrical Wiring Interconnection System (EWIS) Instructions
• GACA Recognized Foreign NAA Notification Letter addressed to the General Manager of Airworthiness (for ongoing certification project)
• Letter of application addressed to the General Manager of Airworthiness (see additional help)
• Master Data List
• Owner/Operator acknowledgment for the proposed design change
• Required Operating Data such as Aircraft Flight Manual Supplement (AFMS)
• Supplemental Type Certificate (STC) or Major Change Approval issued by GACA Recognized Foreign National Aviation Authorities (for existing approved data)

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, a GACA Acceptance Letter will be issued.

Terms and Conditions

• Only GACA-certificated repair stations may perform actual work on Saudi-registered aircraft.
• If the Major Change Approval or STC (issued by GACA Recognized Foreign NAA) is not yet issued, the procedure for Ongoing Certification Project will be used.

Additional Help

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

1. Design Approval holder/applicant name and normal place of business
2. Description of the design change, including:
   • Purpose of the change
   • Pre-modification and post-modification configurations
   • Schematics/pictures and any detailed features and boundaries of the physical change
   • Drawings or outlines of the design
   • Identification of functionally affected areas and changes to maintenance/operational manuals
3. Aircraft type, serial number, and KSA registration marks
4. Organization responsible for performing the alteration on the aircraft
5. Location of the aircraft during the STC project
6. Starting date and duration of the STC project
7. Information on whether flight testing will be conducted
8. Concurrent activities on the aircraft
9. Request for GACA concurrence for using a KSA-registered aircraft as a prototype
10. Request for GACA concurrence for the use of GACA Recognized Foreign NAA Designees, if applicable
11. Request for specific information required to support the GACA Recognized Foreign NAA undue burden process (if applicable)
12. Invitation for GACA participation
13. Identification of the Certification Project Manager(s), including their contact details

Additional Information

1. GACA accepts all design changes (including STCs) introduced by the holder of the TC. This is considered automatic acceptance, with no need for GACA concurrence for implementation on Saudi-registered aircraft.
2. The design change criteria stated in this section also apply to repair designs.
3. For design changes issued by GACA Recognized Foreign NAA and performed on Saudi-registered aircraft, GACA aims to minimize its involvement in the certification process. However, as the State of registry, GACA must understand the design change's nature and may participate in certification activities to ensure proper understanding. This may include meetings, requests for clarifications, and participation in certification inspections and tests as an observer.
