Sorry, perhaps I wasn't being precise enough in my use of English.
I meant that it wasn't (presumably?) a 'new' product to L-3 Communications, as opposed to the RAF, for which it is definitely a new aircraft type.
I therefore thought that, as the firm doing what was for them (presumably) a 'standard conversion', L-3 Communications would have the "big boxes of paperwork" available for the MAA to read whenever they wanted to.
Hopefully that clarifies my previous comment!
