Other activities for Repair Station Certificate
The Civil Aviation Authority of Thailand (CAAT) is the Competent Authority for maintenance organisations that are involved in the maintenance of Thai registered aircraft and components intended for fitment thereto as established by TCAR 8 Part 145.A.1 General.
CAAT is therefore responsible for the final approval of these maintenance organisations and for establishing procedures detailing how TCAR 8 Part 145 applications and approvals are managed.
An application for change of a maintenance organisation approval shall be made in accordance with CAAT TCAR 8 Part 145, 145.A.85 and appendix IIIA, by using CAAT Form 2 and the associated completion instructions detailed in CAAT-GM-AIR-504. The application form should be submitted by CAAT-EMPIC.
An application package for change should include:
The process for a change of approval is similar to the initial process for Document Evaluation, Demonstration and Inspection, and Certification.
Example of changes requiring prior approval by CAAT, please see <EXAMPLE>.
The timeframe related to the approval of a change is highly variable depending upon the nature of the change. The timeframe provided for the processing of an initial approval may be considered as the upper limit. Any fee impact for the change will be advised by CAAT.
As per TCAR 8 Part 145; 145.A.90, an approval shall be issued for a maximum of 3 years.
A continuous monitoring approach is applied between consecutive approvals. The number of audits depends upon the CAAT risk-based assessment (e.g. weakness when dealing with serious or numerous findings, difficulties with closing findings, incidents, etc.). An audit for change does not replace an ad-hoc audit.
At the end of each 3-year validity cycle, an application for renewal may be made in accordance with TCAR 8 Part 145. This must be submitted to CAAT at least 60 days prior to the expiration of the certificate.
A renewal application package must include:
The renewal process is as initial approval phase 2 – phase 5.
In cases where a maintenance organisation wishes to surrender a certificate, this should be notified to CAAT by completion of CAAT Form 2 and submitted by email to firstname.lastname@example.org. CAAT will acknowledge receipt of the form.
Repair Station Obligations
According to TCAR 8 Part 145, 145.A.55(a)(4), where an organisation terminates its operation, all retained maintenance records covering the last three years must be distributed to the last owner or customer of the respective aircraft or component. In addition, in accordance with TCAR 8 Part 145, 145.A.90(c), the certificate of approval must be returned to CAAT.
A suspension of an approval means that CAAT removes, partially or in whole, the ratings endorsed on the certificate and the MOE.
Revocation means that the approval granted is removed in whole and definitively.
The following applies to suspended approvals only.
Following the acceptance of a corrective action plan by CAAT, the maintenance organisation should commence the implementation of the corrective actions.
At the completion of the implementation process, the maintenance organisation should undertake a full audit to assess compliance with TCAR 8 Part 145. Before CAAT can undertake a reinstatement audit, a statement of compliance to Part 145, signed by the maintenance organisation’s compliance monitoring manager, and the relevant audit report must be provided to confirm the effective implementation of the corrective actions.
CAAT will formally notify the maintenance organisation of any reinstatement of approvals.
