If volume fraction of the synthetic blending component is beyond the limits of this CTSO b (2) 1), civil aviation jet fuel containing synthesized hydrocarbons and synthetic blending component shall be evaluated according to ASTM D4054.
d. Testing laboratory
All tests shall be conducted in laboratories approved by CAAC or under the supervision ofCAAC.
e. Deviation
For using alternate or equivalent means of compliance to the criteria in this CTSO, the applicant must show that the product maintains an equivalent level of safety. The applicant must apply for a deviation under the provision of section 21.368 in CCAR-21.
4. Marking
a. The quality certificate and other applicable documents of civil aviation jet fuel containing synthesized hydrocarbons shall mark at least the following information:
(1) Process and standard of synthetic blending components;
(2) CTSO and CTSOA number;
(3) Volume fraction of synthetic blending components;
(4) Manufacturer designation and address;
(5) Manufacture date, quantity and batch number.
b. Annex 1 and Annex 2 are examples of the refinery certificate quality of synthetic blending component and civil aviation jet fuel containing synthesized hydrocarbons.
5. Documents Requirements
The applicant shall submit the responsible documents as follows.
a. Documents for CTSOA application according to CCAR-21;
b. Standards or specifications;
c. Description of feedstock;
d. Description of manufacturing process;
e. Safety data sheet for chemical products (SDS);
f. Other documents required by CAAC.
6. Application Note
After CTSOA authorization, the applicant shall obtain aircraft installation approval. If product standards have already listed in the type certificate data sheets (TCDS), supplemental type certificate (STC) or or other design approval documents, the civil aviation jet fuel containing synthesized hydrocarbons is not essential for installation approval.
