There is a check c/o on every a/c after every flight, this check encompasses many things, it is issued or endorsed by the a/c manufacturer and the regulating authority. If you did or do it you will know.
Problem is that some airlines are fully endorsing the manufacturers recomendations and others are not.
Two spring to mind, no names etc.
Similar a/c type.
Airline 1. The check is drawn up by the airline's maint engineers and involves a separate check sheet. L/G doors open, flaps extended and a thorough inspection signed off in the tech log.
Airline 2. No extra paperwork, transit check unchanged, no communication from the airline's maint engineers regarding any extra detailed checks required.
