B. Where corrosion has already started, refer to Structural Repair Manual for
details of corrosion removal.
C. Apply BMS 3-23 water displacing corrosion inhibiting compound to damaged
finish on exposed surfaces. Refer to Volume 1, 20-60-00 for details of
application of BMS 3-23.
D. After application of BMS 3-23, all grease fittings in the treated areas must
be regreased.
E. Precautions for Use of Corrosion Inhibiting Compound.
CAUTION: DO NOT APPLY BMS 3-23 TO AREAS WHICH WILL BE SUBSEQUENTLY PAINTED OR
SEALED.
OBSERVE PRECAUTIONS OF VOLUME 1, 20-60-00 ABOUT SPRAYING CONTROL
CABLES WITH BMS 3-23.
(1)Apply BMS 3-23 to unpainted hydraulic tubing in the area.
(2)Shield or protect pulleys, wire bundles, etc., in some manner to prevent
direct application of BMS 3-23.
(3)Mask off electrical connectors to avoid application to any electrical
contacts.
(4)
Protect oxygen systems, including fittings, from contamination in accor-dance with chapter 35 of the Maintenance Manual.
(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.
F.
Improved Corrosion Protection:
(1)Forward Trunnion Fuse Pin: Beginning with airplane line number 805, the
forward trunnion fuse pin will be replaced with a pin made from 15-5PH
Cres material and plated with Class 3 chrome. This change is being
incorporated by PRR 54807.

NOSE LANDING GEAR
1. General
A. The nose landing gear is exposed to air contaminants and runway splash which
can cause corrosion.
B. Corrosion can occur in the shutoff valve and the manifold of the steering
meteringvalve module.
2. Corrosion Prevention
A. Make the regular inspections as in Volume 1, 20-00-00, to make sure that
protective finishes stay serviceable. For the steering metering valve mod-ule, refer to SB 32-76 and Parker SB 3800014-32-43. The preferred treatment
for broken finishes is to replace the finish with the same protective system
as used originally. Since in some cases it is impractical or impossible to
use this approach between overhaul cycles, the treatment described in the
following paragraphs is recommended.
B. Where corrosion has already started, refer to Structural Repair Manual for
details of corrosion removal.
