Repetition of limit G-factor

I am an ASIP engineer and we track and help maintaining aircraft service life.

From the structural point of view, the limit load is a load that should occur only once per the aircraft lifetime. Thus, we assume that limit G-factors (say, +9g for F-16 @22,500 lb GW) are achieved rarely. Often repetition of the limit G-factor significantly (could I say dramatically) reduces the aircraft fatigue and service lives.

On the other hand, there are quite a few youtube clips with F-16 HUD reading of 9g. I realize that, during a mission, a pilot may need go that far. I looked at a couple of Flight Manuals and found limit maneuver G-factors but no limitations on their number of occurences.

My question is, do a pilot know that he should not get to the limit G-factor often. Is there a document for the pilot prescribing or limiting the number of limit G occurences?

Thank you.
