What are the various logbooks?

[FirmamentFX]

Hi guys,

I have been searching around the internet, but only found a confusing amount of contradictory information...

Can someone pelase explain what the various logbooks are (and tell me if I have the general idea wrong) on a commercial aircraft.

- Aircraft Logbook : General log of every flight.
- Engine Logbook : Log of engine (hours / faults etc)?
- Aircraft Technical Logbook : How does this differ from the A/C Logbook? Are faults not recorded in the A/C Logbook?
- Maintenance Logbook : Record of maintenance on the A/C? Is this not recorded with the faults in the other logbooks?

Are there any others?

Is the idea of a "logbook" somewhat misleading? Rather than a ledger of each flight, are there several pages of info for each flight/sector?

Many thanks!

A propeller log book for variable pitch props too, I think.

Hope this helps.

2. the total time and flight cycles as appropriate, of the aircraft and all life-limited components, at least 12 months after the aircraft or component has been permanently withdrawn from service, and;
3. the time and flight cycles as appropriate, since last scheduled maintenance of the component subjected to a
service life limit, at least until the component scheduled maintenance has been superseded by another scheduled maintenance of equivalent work scope and detail, and;
4. the current status of compliance with maintenance programme such that compliance with the approved aircraft maintenance programme can be established, at least until the aircraft or component scheduled maintenance has been superseded by other scheduled maintenance of equivalent work scope and detail, and;
5. the current status of airworthiness directives applicable to the aircraft and components, at least 12 months after the aircraft or component has been permanently withdrawn from service, and;
6. details of current modifications and repairs to the aircraft, engine(s), propeller(s) and any other component vital to flight safety, at least 12 months after they have been permanently withdrawn from service.

M.A.306 Operator's technical log system

Thanks to you both!

The prop logbook had passed me by completely...!

Those regs are very useful thanks! :-)
