Tech Log, Maintenance Log, Pilot Log
I don't know of any reg that either requires or prohibits the carrying of the maintenance logs (I'm not talking about the aircraft Tech Log.) on board the aircraft when the aircraft is going to fly. I may be ignorant. However, I've always considered it 'not a good idea' to carrry these legal documents on the aircraft during flight.
In the past, what I've done, is to FedEx (I'm not doing an ad for FedEx here in PPrune.) the maintenance logs to my destination. Maybe send them the day before my flight...so they arrive close to the time of my arrival. That way, these legal documents are protected from the crash of said aircraft. It's expensive to do this, but a good idea.
The main problem is the loss of these important records in the event of a crash. The investigating authorities will not have available important histories for accident investigation.
Sorry I cannot quote any regulation pro or con.
