Bjorn,
Thank for the info. I think the database is fine the way it is. It would be impossible to follow each specific update.
basher54321,
Again, AFAIK, MLU is not a black and white update. Is not item A through D. Each country did theirs differently. So unless you have access to each aircraft jacked files and can tell me all ECP/TCTO they receive and when, we have no idea what updates they went through while undergoing MLU.
Additionally, again AFAIK (I am not expert on any of this) F100-PW-220E are updated F100-PW-100/200, not newly bought engines.
Finally, about the tapes, they would have a TCTO/ECP number to them. You would need specifics on what aircraft got updated when.
Have you ever seen a F-16 Technical Manual (or Tech Order /T.O) Typically on the front of the books they list the TCTO/ECP that are relevant to that specific TO. They also list the specific serial numbers of they aircraft that manual applies to.
here is a F-16A-1 for example

So updates are not black and white, you would have to know specifics on each aircraft.
