Logbooks yes. I have the logbooks. But logbooks don't contain the
*details* of work done. They should contain references to other
documents. For example a logbook might say that a 100hr check was
done. What it won't say (unless the engineer felt like writing it in
there) is that the landing gear gas seals had to be replaced and two
instrument panel light had to be replaced, etc; that will be in a
separate file which is referenced in the logbook.

My question was whether *** under FAA rules *** the aircraft owner is
entitled to have a copy of these separate files.

Under FAA rules, the logbooks themselves must contain the details of the work.
