Log book post dated entries

[APACHE 56]

I am selling my Skybolt and in getting the logs ready for inspection I have discovered that I never entered the Lycoming oil pump AD 96-09-10. The sticky note is there with all the data but never got transcribed into the engine log. How do I make the correction?
Thanks,
Don

It is acceptable to make AD logbook entries in the back of the logbook.
