HORIZONTAL STABILATOR REMOVAL/INSTALLATION – continued
2.113.7. Corrosion Prevention
CAUTION
Do not apply corrosion preventive compound (item 63, App F) on individual components prior to or
during installation. Application will result in a wet (lubricated) torque which can cause a much higher
torque value than specified.
NOTE
New horizontal stabilator and/or new hardware initially require two applications of corrosion
preventive compound (item 63, App F) which must be applied in intervals at least 1 HOUR apart.
When applying corrosion preventive compound (item 63, App F), use the precision (drinking straw-
like) applicator attached to the spray head of aerosol can.
After 2 MINUTES, wipe excess corrosion preventive compound (item 63, App F) from applied area.
a. Apply corrosion preventive compound (item 63, App F) to horizontal stabilator hinge assemblies.
(1) Make application in single short duration squirts, to following areas:
(a) Between the nut and the vertical stabilizer ear.
(b) Between vertical stabilizer ears and horizontal stabilator ears (three places on each hinge assembly).
b. Inspect (QA).
c. Secure access doors LS1 and RS1 (para 2.2).
d. Install access fairings L545 and R545 (para 2.2).
