Do I need a separate log book for my self sustainer engine (turbo)?
(15 August 2007) No. Using the same process before transition, the engine can be treated as a component and details recorded in the old BGA log book. The engine hours should be recorded on the log book page as a written entry, annually or whenever there is a maintenance check. As an option, an owner can run a CAA engine log book (CAP 399) in addition the the airframe log book (CAP 398). Please note that CAA log books are not required for transition, but if a CAA logbook is utilised we recommend that if the “turbo” is used, say, in excess of about 5 hours per year, it would be sensible to run an engine log book.
