Moreover, can the maintenance organisation say that they must keep a
copy, and charge me (whatever they like) for making a copy?

Thank you for any feedback.



As far as I am aware, an FAA certified A&P has to put records of work in the
aircraft logs. He may charge you for the entry, but he has to make it or,
depending on the work, he could risk his certificate. Many A&P's charge
hourly rates for the time they spend on your paper work.
