CAAC (Civil Aviation Administration of China), PMA Certification and CTSO Burn Test
21. July 2023The Civil Aviation Administration of China (CAAC) is the national administration responsible for civil aviation in China. CAAC drafts laws, rules, regulations, and policies and standards related to civil aviation.
In addition to aviation, the safety regulation of related aviation products is also subordinate to CAAC. To ensure the airworthiness of civil aviation products and parts, the CAAC formulated the Regulations on Conformity Certification of Civil Aviation Products and Parts (number, CCAR-21-R4), which was issued on May 24, 2017, and forms the basis for the type qualification certification, production license certification, and airworthiness qualification certification of all civil aviation products and parts.
Parts Manufacturer Approval (PMA)
This regulation contains the application, issuance and administration of the various certificates or approvals. Among them, “Parts Manufacturer Approval” (PMA) is a letter of approval issued to manufacturers of civil aviation products that have been type qualified or type approved for replacement or modification. Airlines can award production contracts to manufacturers with PMAs. PMA parts significantly reduce maintenance and other costs for commercial air carriers compared to expensive OEM parts.
CTSO Tests (Civil Aviation Product Technical Standard Specification Items)
In addition to CCAR-21-R4, the CAAC also developed the CTSO (Civil Aviation Product Technical Standard Specification Items), which means that in addition to requiring the previous manufacturer to comply with the regulations, its products must also undergo various performance and environmental tests in accordance with the CTSO requirements. Depending on the product, CTSO is divided into CTSO-CXXX or CTSO-2CXXX categories, etc.).
In accordance with the requirements of the CTSO 2C-601 performance standard, products can be tested on seven items: Dimensional stability, pile pull-out strength, appearance retention, antistatic property, vertical combustion within 12 seconds, smoke density and toxic gases.
If you are interested in PMA certificate, especially if your product needs to be tested according to the relevant combustion tests, please feel free to contact us.
