Section 8
Handling, Serv & Maint
Do not expose control surface trim tab
hinge lines and their pushrod systems to
the direct stream or spray of high-pressure,
soap and water washing equipment. Fluid
dispensed at high pressure could remove
the protective lubricant, allowing moisture
from heavy or prolonged rain to collect at
hinge lines, and then to freeze at low tem-
peratures. After high pressure or hand
washing, and at each periodic inspection,
lubricate trim tab hinge lines and trim tab
pushrod end fittings (Brayco 300 per Fed-
eral Specification VV-L-800 preferred). See
the Baron Maintenance Manual.
When using high-pressure washing equipment, keep the spray
or stream clear of wheel bearings, propeller hub bearings, etc.,
and openings such as pitot tubes, static air buttons, and bat-
tery and avionic equipment cooling ducts, which should be
securely covered or masked off. Avoid directing high-pressure
sprays toward the fuselage, wings, and empennage from the
rear, where moisture and chemicals might more easily enter
the structure, causing corrosion damage to structural members
and moving parts.
When cleaning landing gear areas with sol-
vent, especially if high-pressure equipment
is used, exercise care to avoid washing
away grease from landing gear compo-
nents. After washing the landing gear areas
with solvent, lubricate all lubrication points,
or premature wear may result.
