Subtask 57-55-00-040-053-A
A. Preparation of the Aircraft for Flight After Damage to the Flap-Track Fairing Seals
CAUTION: BE CAREFUL WHEN YOU DO MAINTENANCE TASKS ON THE WING TRAILING EDGE:
  • DO NOT CAUSE DAMAGE TO THE ELECTRICAL CABLE RACEWAYS.
  • DO NOT CAUSE DAMAGE TO THE ELECTRICAL CABLE INSTALLATIONS.
  • MAKE SURE THAT THE ELECTRICAL CABLES ARE INSTALLED CORRECTLY. INCORRECT INSTALLATION CAN CAUSE DAMAGE.
   (1) To cut the damaged movable fairing seals:
NOTE: Be careful not to damage the adjacent structure when you remove loose or damaged seal.

     (b) Use a Textile-Lint free Cotton - (Material No.14SBA1) , made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean the area around the removed seal.
     (c) Apply the Adhesive Film Tape-- Aluminium Foil - (Material No.05RAB9) to the area where the damaged seal has been removed.
     (d) Apply the tape between the fairing and the bottom wing skin. Make sure that it gives the same seal effect as the initial seal.
     (e) Make the tape smooth from the center to the edges to remove air bubbles and push the edges down tightly.
NOTE: When you cut the tape, make sure there are no cuts or overlaps in the direction of flight.
     (f) Make a note in the aircraft log that the seal has been temporarily repaired.
