Aircraft Maintenance | Maintenance of a foreign aircraft is a periodic inspection of the technical condition of the aircraft and must be performed by the airline (maintenance company) after a certain amount of time or a certain amount of flight time (as defined in the airline’s maintenance program). There are transit checks, daily checks, A-checks, B-checks, and C-checks; A and B-checks are simple (easy) checks, while C and D-checks are more difficult maintenance.
Aircraft Maintenance, How does it work?
A transit check is the simplest form of aircraft maintenance. It is done before each flight of an aircraft.
Routine Inspection – A routine inspection of the technical condition of the aircraft must be performed every 24 hours, but in some cases, it can be done after 36 hours. It is usually done at night.
Check about once a week. Can be conducted at any time of the day or night. No room (hangar) is required. Usually takes 3-4 hours to perform.
A-check – This check is done about once a month or every 500 hours of flight: A1, A2, A4, A8. The higher the number, the more work; the A-check is usually done at night in an airport hangar. The content of this check depends on the type of aircraft, the number of cycles (the number of takeoffs and landings is called a “cycle”), and the number of hours flown since the last check. Depending on the conditions, the check may be delayed by the airline.
B-check – This check is done about every three months. It is also commonly done at night in airport hangars.
C-check – This form of maintenance is more complex than the previous one and is performed every 15 to 20 months or 4,000 flight hours. In this form, the maintenance is divided into C1, C2, C4, C6, and C8. This inspection requires taking the aircraft out of service for a while (about two weeks) and also requires a lot of space – usually in a large hangar at the airport. The timing of this check depends on a variety of factors, especially depending on the type of aircraft.
The D-check is the heaviest form of aircraft maintenance. This check is done about once every 12 years, for about 30-40 days. The entire fuselage, all parts, and pieces are checked. Any units that have reached the end of their life or have not been tested will need to be replaced. The inspection of this aircraft requires even more space and time than all other aircraft and is done on a proper technical basis.

SV (store visits) – a heavy form of aircraft maintenance. Frequency (average) – 12,000 flight hours.
