Roger is an unknown quantity at this point
My original post was meant to discuss the possibility that the extreme use (and possible operations outside of the normal envelope due to military use) of 02's could perhaps cause harm to the data set used by the FAA. This has then brought up the question of operations of 336/337's in environments that are also outside of "normal".

The better question would perhaps be: If a 336/337 or 02 was used in a category other than "normal" and or was used under 91.323 in Alaska allowing for heavier gross weight, should it be used in the data set?

For precedent, the FAA should be asked if the 400 series data that was used to predicate the AD included aircraft that were "known" to have exceded their "normal civilian" operating parameters. If the answer is no, then clearly the FAA should not use 336/337-02 aricraft that were knowingly operated outside of the aircrafts civilian standard operating envelope and weight limitations.

Of course there are aircraft that have been operated outside of their normal envelope on "occasion or by accident" but that is something that would be virtually impossible to know. However if the non-standard operations are known, those aircraft should be excluded with out question.
