Application for Production Organisation Approval

To engage in the production of parts and articles to be fitted onto Singapore registered aircraft, your organisation will need to fulfill certain requirements such as the right organisational structure, procedures, competencies and resources. If all requirements are fulfilled, CAAS will then grant a Production Organisation Approval (POA) to your organisation. Overseas organisations, engaging in production activities in support of the Singapore aviation industry, may also apply for a POA.

The specific requirements for a POA can be found in the Singapore Airworthiness Requirements (SAR) Part 21, in Subpart J and Subsection VI.
