None at all. A prosecution of a pilot/engineer/inspector/etc would be subject to exactly the same tests by the CPS as any other criminal prosecution: is there a reasonable probability of a conviction and is the prosecution in the public interest?
Incidentally, the defence in both of the two aforementioned cases (albeit one of them didn't get to court) involved challenging the findings of the respective AAIB investigations.
