The use of the CAA CAP 741 logbook is voluntary thus it can be used to log as much information as the holder wishes. Note: In accordance with AMC 66.A.45(d) a record of experience is required - see also Part145.A.35(j) requiring staff records of all relevant training. However, it is not mandatory that every single task is logged i.e. minor maintenance or simple checks. It is advised that any tasks carried out relating to licence issue or an extension to a licence, be logged.
