Certification

An aircraft’s basic configuration has a type certificate (TC). All retrofit equipment installed must be approved with a Supplement Type Certificate (STC). An STC means that the certifying civil aviation authority has approved both the system and its installation from an airworthiness viewpoint.

Within the EU STCs are often issued by the EASA. An STC issued by the FAA (Federal Aviation Authority in the USA) is in reality the same as global certification. CTT and Lufthansa Technik have a co-operation agreement regarding certification.

This agreement means that Lufthansa Technik acts as CTT:s formal design organization and maintains STCs for CTT products in return for royalties on systems sold. This agreement is very useful in the sales process as Lufthansa Technik has an excellent reputation for certification, and affords the possibility of maintaining STCs from both the EASA and FAA.
