What are the main features of checks "A, B, C, D"?

To make sure you know your alphabet, it is an exam usually taken in pre-school.

Obviously my question refers to the checks airliners will get.  Smile

I don't think the airliners need to know their alphabet for obvious reason.

LOL.. An 'A' check occurs after every X number of flight hours and is usually done overnight. A 'B' check is more complex and happens after XX flight hours.C and D checks are major overhalls and take weeks to perform. This is a very simplified explanation, but it gives you an idea of how the system works.

Sometimes the A-check might take longer...for example, at Finnair it took us at least a couple of days to do the A-check for Air Liberté DC-10-30s.....

In D-check, everything that goes off, is taken away from the aircraft (the main hull; the pipe) and is sent to their respective departments. The painting is removed etc. and as you said, takes weeks to accomplish.

One could describe the D-check as a 2-way puzzle: first you put it into small pieces, and after checking everything, put them back together. But it's a one hell of a puzzle  Big grin

1740 days idle. Beat that.
