In the time remaining, please describe the work that is done.
Am I right to say that maintenance consists in changing a tire, for example? That is small maintenance. You are dealing with big aircraft, but that is small maintenance work that can be done overnight or in one day. You take advantage of the night time or morning, when the aircraft is not flying, to carry out repairs. That is small maintenance.
However, how long does it usually take to overhaul an aircraft?
