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.
An aircraft used for hire in a Flying Club is required to have exactly the same Tech Log as an aircraft used on an AOC and to be maintained to the same standard according to the CAA Licensing Standards. With the demise of CAP520 there now appears to be no guidance on what is actually requited; no wonder there is confusion.
