Worn Out Washers
B
lack Hawk repairmen, a quick glance at the control rods is simply not enough to
spot bad nylon washers during your scheduled PMS-1 checklist inspections.
The control rods connect primary servos to the swashplate, which controls air-
craft flight.
A bad washer could spell curtains for you and your bird if you don’t
thoroughly inspect the rods. That could lead to flight control failure.
So during your 30-hr/42-day
flight control inspection, eyeball
the control rods closely and check
for everything that sequence num-
ber 6.4 of TM 1-1520-237-PMS-1
tells you to.
Make especially sure
the nylon washers haven’t begun
to peel off the control rods from
wear and tear.
If you have bad washers,
replace ‘em like it says in section
11-4 of TM 1-1520-237-23-6.
Check control rods for

Engines
Sand gets trapped in excess
grease and forms a paste that wears
out lubricated parts. Keep the
engine inlet cover on and tight. If it
blows off, or doesn’t seal the inlet,
the engine will fill with sand. Then
you can kiss your engine goodbye.
Rotor Blades
Other Areas
Tape all openings or seams around
windows, chin bubbles, and access
panels. Be thorough, but be sure you
don’t stop airflow that is needed to
cool parts.
Of course, always check out TM
1-1500-204-23-1 and FM 1-202,
Environmental Flight,
for other hot
weather and desert environment tips.
Your engine
can also fall
victim to the
destructive
power of
sand.
Plug engine to
keep sand out
Sand in the
air tears into
leading edges
of your bird’s
rotor blades.
“Look for blade erosion after
every flight and clean ‘em and
cover them like your TM says.”
