It took 5 and a half years for the AJR-21 to obtain the test certificate, how long will it take for the C919 to get its flight permit?
COMAC released the news that six C919 test aircraft completed all test flight tasks and made every effort to obtain airworthiness certificates. Translating it, the original single-threaded task has become 6 threads running, but to obtain the test certificate, the time may not be 1/6 of the original!
As mentioned here, an airworthiness certificate is the management and technical implementation process that ensures that an aircraft meets the minimum acceptable safety standards (airworthiness standards) established in accordance with public requirements. The application process is extremely complex, in addition to verifying that the aircraft meets the existing airworthiness requirements, COMAC also provides sufficient calculations, data, tests and other means to show the Civil Aviation Administration of China that its C919 has airworthiness requirements - that is, it can fly safely and effectively. Subsequently, after completing the airworthiness verification + verification + obtaining the airworthiness certificate, the C919 can be put into the market.
The previous ARJ-21 took 5 and a half years to obtain the test certificate, even if 6 C919s flew at the same time, it is estimated that it will take at least 1-3 years. After all, civil aviation aircraft are considered by both safety and economy. Safe but not profitable, there will be no market.
Therefore, you don't have to worry, the C919 forensic progress will inevitably be much faster than the ARJ-21, but how early can be done on the C919, it really takes time. What's more, if you want to travel abroad in A C919, it may take a longer time.
By the way, all the parts of C919 basically have parallel replacement manufacturers in China, in case of emergency. However, the total of nearly 60% of international procurement is actually to make C919 "go abroad" as soon as possible. After all, everyone is a community of interests, and only then can we have the motivation to move things forward.
