A little confussion ?
It would seem that the diference between Aircraft/Engine/propeller log books and the Technical log is not fully understood by some.
The Technical log is used to record the day to day flying and maintenance of the aircraft, it should be kept with the aircraft and a copy of the page relating to the last flight and actions taken before the next flight left on the ground when the aircraft flys.
The aircraft log books (one for each airframe, engine & VP prop) should contain the life history of the airframe/engine/prop. details such as flying hours and maintenance are taken from the tech log and entered in the Log books. In practice the log books don't have all the maintenance records because these are held on maintenance job sheets by the maintenance company however the log book entrys must include reference to the job sheets and so are the centre point of the paper trail. Log books NEVER fly with the aircraft.
Technical logs are mandatory for AoC work and at one time those aircraft on the old CAA public transport C of A's. As you can see the documents that most flying clubs call a Technical log is no more than a "pumped up" journey log that is all that is required on private aircraft.
