Don't you worry captaintunedog777 you keep walking around telling us that the brake is nearly worn.
Just pop back up into the cockpit and have yourself a nice cup of coffee now.
I think there is a significant difference between the top and bottom of the wing. I guess you only worry about what you can see from the bottom.
You let us worry about the rest. Have a nice day.
ps. The cap you are refering to in on the pressure refuelling manifold which has a valve which is manually actuated by the refueller. Further downstream are automatic valves which open to let fuel into the desired tank. So yes the cap on the pressure refuelling point may be MEL'd. But even a student pilot knows that the cap on top of the wing needs to be in place. That is a direct opening to the tank. The article clearly stated the cap was balancing on top of the wing.
