If it's a working aircraft, chances are something will be added or modified during the life of the airframe. You can record the details in the Airframe Log, but sometimes it's easier if the mods (for example, a set of floats) have their own separate logbook
Technical logbooks form the core of the familiar Canadian aircraft technical record keeping system. The logs are three-hole drilled for keeping in a ring binder or Tech Log Book. Vary the number of engine and prop volumes for multi-engine aircraft. The 5 sections are ordered separately, depending on the number of engines, props, etc. Each tech record can be bound with all the others into the Tech Log Binder to make up the complete aircraft Technical Record. When bound together, the entire log is almost indestructible, yet each record can be removed easily for updating at any time.
