I'm not particularly concerned for these 25% random checks... (I'm not thrilled)....but it most certainly does not have me losing any sleep.
I always fly SOP, and during Annual Line checks there are always some minor points that are picked up....I listen to them, I take them on board and then try to fix those minor errors.
These checkers doing these (25%) random checks are probably not particularly happy about them either, and I expect that they will treat them as any other normal annual line check...a few slight errors they will point out to me, I'll take them on board, read the reports, see mainly 4's with maybe one or two 3's (hopefully a couple 5's!!!).
Then I'll jump into my silver shark or blue German mobile and go home.
The guys checking you are human also....just do a normal flight (my annual line check to KHI is always very normal), and then I'll get some scores (hopefully mainly 4's)...and then it's silver shark time again.
I'm not terribly concerned about this.
Eternity.
