Subtask 57-41-37-210-060-C ** ON A/C NOT FOR ALL

A. Preparation for Installation
(1) Do an inspection of the sealant between the trailing edge of the panel and the forward edge of the wing skin.
(2) If there is damage to the sealant, do the steps that follow:
(a) Use a SCRAPER - NON METALLIC and a Textile-Lint free Cotton - (Material No.14SBA1) made moist with Non Aqueous Cleaner-General - - (Material No.08BAA9) to clean:

the trailing edge of the panel
the forward edge of the bottom wing skin.

(b) Apply Release Agent-- Liquid Wax - (Material No.14DBB1) to the trailing edge of the panel.

B. Preparation for Installation of the Panel 522NB( 622NB)
(1) Do a visual inspection of the panel to make sure that the Epoxy Adhesive-- - Legacy 3 (Material No.05EML7) does not cause a blockage of the notch edge and the drain hole.
(2) If necessary, remove the Epoxy Adhesive-- - Legacy 3 (Material No.05EML7) that causes a blockage of the notch edge and the drain hole.
