Aircraft tech log - liability
Hello!
I recently flew a SEP aircraft which had a well-known unserviceability which should have been (in my opinion) fixed hundreds of hours ago. The owner was fair enough to notify me before doing the preflight during which it was clear the unserviceability existed. But looking through aircraft tech log, there is no sign of reported (written) unserviceability.
The question follows: I know that I as PIC am responsible for doing complete and thorough preflight inspection, but am I legally responsible to write any unserviceability in the aircraft tech log? I would like to have a legal basis for being "pain in the ass" and writing up every aircraft unserviceability.
