Air Astana Group simultaneously conducts six year and twelve year C-Checks for the first time

Air Astana Group is simultaneously conducting 6-year and 12-year C-Check on
Airbus A320 family aircraft for the first time. The complex maintenance procedure is
being carried out at the Engineering centre in Astana.

Both procedures are among the most complex types of maintenance requiring
almost complete disassembly of the aircraft followed by test flights to confirm full
serviceability. These inspections cover all aircraft systems, with the 6-year C-Check
limited the standard depth of inspection and the 12-year C-Check including
expanded inspection of structures and components.

Conducting such specialist inspections require highest level of qualification for
engineering and technical staff, and compliance with international aviation safety
standards.

Since 2019, Air Astana has independently performed 42 C-Checks based at the
Engineering centres of Almaty and Astana, including the first 6-year C-Check in 2023
and first 12-year C-Check in 2024. The current simultaneous 6-year and 12-year C-
Checks are respectively being undertaken on an Air Astana Airbus A321neo and a
FlyArystan Airbus A320ceo.
