You have basically three/four dates on all the record cards.
My interpretation of these dates are
Acceptance date: Date when someone from the AAF has made a physical examination of the aircraft in question (don't know if it also included a checkflight)
Available date: Date when the manufacturer advise the AAF that the aircraft is ready
Delivery date: When aircraft is physically delivered into the hands of the AAF.
After that you usually find a departure date, which is when the aircraft is flown away. Often the same date as delivery date, but weather, crew problems and so on could delay the actual physical departure.

Cheers
