The Component Log is for helicopter components. Helicopters have many more time-limited components than airplanes, many of which are small components which are exchanged or overhauled on their own schedule. This log consists of separate log sheets which can be mated to individual components.
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 engines 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.
