CARGO DOORS
1. General
A. Areas of possible corrosion are the internal structure of the door, connec-tion points and mechanisms. The cargo door should be treated at the same
time as the cargo door opening.
B. On airplanes line number 74 and on, BMS 3-23 corrosion inhibiting compound
was applied to the interior of all cargo doors.
2. Corrosion Prevention
A. Make periodic inspections as described in Volume 1, 20-20-00 to ensure that
the protective finishes provided during manufacture remain intact.
(1)Remove liner and gain access to interior structure of the door.
(2)Clean out drains and drain paths.
(3)Refer to Volume 1, 20-60-00 for details on the application of corrosion
inhibiting compound.
(4)Apply corrosion inhibiting compound to the interior of the door, giving
special attention to the lower corners.
(5)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.
(6)Do not apply corrosion inhibiting compounds on interior materials such
as cargo liners. The compounds change the flammable quality of these
materials.
(7)Relubricate interior door fittings as necessary per the maintenance man-ual.
(8)
Reinstall liner and restore door to normal.
B.
Frequency of Application. Periodically inspect the door structure and con-dition of the corrosion inhibitor. Reapply corrosion inhibiting compound as
required. Local areas where gouges and scratches have occurred should be
treated at the first opportunity consistent with the maintenance schedule.
