Base Maintenance
World’s first

In April, STAECO completed its first 4C-check on an ARJ21-799 aircraft manufactured by China’s state-owned aerospace company, COMAC; this was also the world’s first 4C check on the ARJ21-700 aircraft type.


The successful completion of this input has laid a solid foundation for future maintenance checks on the ARJ-700 family. The STAECO team devoted a huge amount of effort to ensuring the requirements of the customer and the regulatory authority were met and the aircraft was redelivered to the customer after completing a test flight from Jinan Yaoqiang Airport to Xian Liangliang Airport.
