(i)
Install liners and floor panels. Install the floor panel fasteners
with BMS 3-24 grease.
(j)
Apply water displacing corrosion inhibiting compound to skin and
structure in Section 48. Refer to 53-70-01 for corrosion prevention
of the aft pressure bulkhead which should be treated concurrently.
(4)No. 2 and 3 Cargo and No. 4 Passenger Door Opening
(a)
Treatment of the door at the same time as the door opening is recom-mended.
(b)
Remove traffic debris and generally clean the entire door opening
area. Remove reveal and scuff plate where applicable.
(c)
Replace damaged or broken finishes if at all possible. Refer to Vol-ume 1, 20-60-00 for protective finish systems.
(d)
Relubricate all tube points per standard servicing procedures.
(e)
Where accessible, apply corrosion inhibitor to the internal lower
still area.
(f)
Special effort should be made to apply the corrosion inhibitor along
doubter edges, along faying surfaces and on fastener heads. Spray
all doors and fuselage fittings at the faying surfaces. The use of
spray equipment with nozzle directed into faying surface is recom-mended.
(5)Do not apply corrosion inhibiting compounds on interior materials such
as cargo liners. The compounds change the flammable quality of these
materials.
(6)Do not apply corrosion inhibiting compounds on insulation blankets. The
compounds reduce the water-repellent quality of the blankets.
(7)
Do not apply corrosion inhibiting compounds on grease joints or sealed
bearings. These compounds dissolve grease and other Lubricants. They are
penetrating compounds and can get around the seals and into the bear-ings.
E.
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 to areas identi-fied and should be consistent to the schedule specified in the Mainte-nance Planning Document.
F.
Improved Corrosion Protection
(1)On airplanes line number 328 and on, PRR 54313 added BMS 3-26 corrosion
preventive compound in the bilge area below the cargo floor.
(2)On airplanes line number 721 and on, PRR 54530-143 added two coats of
BMS 10-11, Type 1, primer to many stringers, doubters, panels, splices
and fillers in the section 46 cargo compartment. This came as a result
