What was found
(CAN) WINDOW RETAINERS OF WINDOWS 2 AND 3 IN THE PASSENGER COMPARTMENT WERE FOUND TO BE CORRODED. THE CORROSION IS DIFFICULT TO SEE WHEN THE WINDOW SHADE ASSEMBLY IS INSTALLED BUT OBVIOUS WHEN SHADES ARE REMOVED. SUBMITTER STATED LEAKING SEALS OF THE WINDOW RETAINERS COULD CONTRIBUTE TO SERIOUS FUSELAGE CORROSION.
