4. Procedure
Subtask 52-33-13-340-050-A
A. General Repair Procedure for the Bulk Cargo-Door Linings
   (1) Find the damage type:
  • Cracks/holes in the bulk cargo-door lining (material broken or missing)
  • Damage on the edges of the bulk cargo-door lining.
   (2) Measure the damaged area:
     (a) For the cracks/holes in the bulk cargo-door lining:
  • L = the length of the damage
  • W = the width of the damage
  • DH = the distance between the new damage area and the existing repaired area or a different damage area.
NOTE: If the distance between two damaged areas is less than 100 mm (3.94 in.), the two damaged areas become one damaged area.
     (b) For damage on the edges of the bulk cargo-door lining:
  • L = the length of the damage along the edge
  • W = the width of the damage
  • DE = the distance between two new damaged areas or between the new damaged area and the existing repaired area
  • LE = the total length of the damage areas along the edge
  • DS = the distance between the new damaged area and the existing repaired area.
NOTE: If the distance between two damaged areas is less than 25 mm (0.98 in.), the two damaged areas become one damaged area.
   (3) Refer to the repair flow chart to find the applicable procedure to repair the bulk cargo-door linings.
   (4) If applicable:
     (a) Replace the bulk cargo-door linings (Ref. AMM TASK 52-33-13-000-001) and (Ref. AMM TASK 52-33-13-400-001).
     (b) Use the wet lay-up repair with rivets from the rear side of the lining procedure to repair the damaged bulk cargo-door lining (Ref. AMM TASK 52-33-13-340-801).
     (c) Use the wet lay-up repair with rivets from the front side of the lining procedure to repair the damaged bulk cargo-door lining (Ref. AMM TASK 52-33-13-340-801).
