Unsafe Condition

Improper sealing of the aerodynamic seals of the Wing-to-Fuselage Fairings can cause rain, washwater, or de-icing fluids to leak onto the aileron pulleys in the LH and RH Main Landing Gear wheel bays. Exposure to leaked moisture in freezing conditions can result in restricted aileron control movement or higher control forces, potentially leading to partial loss of control.

Required Actions

Inspect the aerodynamic seals of the Wing-to-Fuselage Fairings for deviations, including fit, damage, and abrasion-resistant coating condition. Apply improved sealing by installing a new seal, restoring protective coating, correcting fairing position, and sealing gaps between fairings and surrounding structure as necessary.
