There is no set amount here. I have heard 25% off total price for
missing logs (totally missing). There is something in the FARS about
re-creating lost logs. That is what I would do if I owned the plane.

(???) IIUC, they are merely attempting to recreate the logs from INVOCIES,
not from shop records (copies of original work).

Also, the OP is in SOuth Africa (?) -- how do THEIR laws figure in?

Just create a log for each invoice or something similar. Sign it off as
"recreated log".

Are the invoices even close to the level of detail as shop records?

Better than nothing. I guess I'd argue for 25% of the
value remaining on the engine until TBO? So if the engine is 50% to
TBO, and a zero time is 40k, then 5k off. (25% of 20k)?

That'd work!
