(10)Replace or repair broken or damaged leveling compounds used for drain-age.
(11)Apply corrosion inhibiting compound to all exposed structure under gal-leys and lavatories except where the crew oxygen bottle is located.
Exposed structure of bulkheads should also be included. Special effort
should be made to apply the corrosion inhibitor to the top of the floor
beams where moisture may be trapped between the floor panel and floor
beam. The use of spray equipment with nozzle directed into faying sur-faces is recommended. Do not apply excessively.

(12)Allow solvent in the corrosion inhibitor to evaporate before reinstall-ing insulation blankets.
(13)Installblankets so they are taut.
(14)Reinstall liners and floor panels and restore airplane to normal.
(15)Do not apply corrosion inhibiting compounds on interior materials such
as liners. The compounds change the flammable quality of these materi-als.
(16)Do
not apply corrosion inhibiting compounds on insulation blankets. The
compounds reduce the water-repellent quality of the blankets.

Frequency of Application
(1)Periodic inspection is required in areas identified as susceptible to
corrosion and should be consistent to the schedules specified in the
Maintenance Planning Document. Operators must be aware of reported prob-lems and areas of occurrences.
(2)Periodic application of BMS 3-23 compound is necessary in areas identi-
fied and should be consistent to the schedule specified in the Mainte-nance Planning Document.
(3)Remove ceiling lining for access to main deck floor beams and intercos-tals.
(4)Open any plugged drains.
(5)Clear all drain paths.
(6)Replace broken or damaged finishes. Refer to Volume 1, 20-60-00 for pro-tective finish systems. Use interior finish system with polyurethane
enamel topcoat.
(7)Replace or repair broken or damaged leveling compounds used for drain-age.
(8)Apply corrosion inhibiting compound to all exposed structure under gal-leys and lavatories except where the crew oxygen bottle is located.
Exposed structure of bulkheads should also be included. Special effort

beams where moisture may be trapped between the floor panel and floor
beam. The use of spray equipment with nozzle directed into faying sur-faces is recommended. Do not apply excessively.
