Can anyone tell me what the undimpled holes in the F-01484 Center Bottom Skin are used for? The ones circled red in the plans attached. I know the aft-most set of 3 (green ones) are for the transponder antenna, but I'm unsure of the purpose of the other 5 holes. I don't see them referenced anywhere in subsequent chapters. Is there any problem if the bottom skin was dimpled in the wrong direction and these holes are on the left side rather than the right? Asking for a friend.
