I need a little help with this one. It used to repair it before? I never or at least did not in the last few months armored an aircraft. If you armor a car, it does not repair the bodywork, it just sets the HP to 1500 instead of your current vehicle HP, but for example the tires are not going to be restored. Maybe it's the same for airplane wings? They are considered bodywork I think and you need to repair the bodywork to actually repar the wings? Also another example would be if you miss a car door and only armor it, it wont give you the car door back.
