Well he further states in the article
During the external pre-flight walk-around we do before each flight, it is very important to ensure the rubber sealing at the wing-root , wheel-well area etc are all well secure /intact / not worn out etc. or in case if there is partial door open during flight as ambient cold air entering the Main Wheel bay could lead to erroneous indication.
I guess this would be the case for 15 odd years old aircraft. I guess I do not have to worry about it as our fleet is virtually brand new
