echanics, lifting your Kiowa Warrior for ground handling may seem simple, but
there’s one important protection you shouldn’t forget. Make sure you’re wearing
safety goggles.
Because the ground handling wheels
(GHW), NSN 1730-01-382-8031 and NSN
1730-01-133-9204, operate under hydraulic
pressure, you’ll need to protect your eyes.
That’s because when using the GHW’s
hydraulic hand pump to apply lift pressure
to the aircraft, a mishap can sometimes
happen. For instance, hydraulic lines can
break or a loose line may pop off. When
that happens to a pressurized line, hydraulic
±uid spews out with a lot of force. Wearing
goggles keeps your eyes out of harm’s way.
‘Course, when using GHWs, always
make sure you and your fellow mechanic
pump the wheels on both sides of the skids
in unison. This keeps the aircraft level and
equalizes the pressure in both GHW’s.
As with any piece of hydraulic equipment, don’t ignore your GHW’s PMCS
or general maintenance. Check oil reservoirs for proper levels and lube as required.
Do all your

PMCS like it says in TM 1-1730-232-13&P and
the wheels will perform like a champ every time you need them to lift and move
your aircraft.

ome of the smallest things can cause some of the biggest problems when you rush through
the details of Chinook PMCS, mechanics.
Checking the forward and aft work platform doors isn’t optional or something you
do on a whim. You must inspect the doors
daily
like it says in TM 1-1520-240-PMS1 and
TM 1-1520-271-PMS1,
Preventative Maintenance Services Modular Daily Inspection Checklist.
For example, the right and left forward/
aft pylon work platform door latches may
seem like small things, but if you don’t
check the latch pins for wear, security
and elongation, the doors can come open
suddenly during flight. And if the cables or
hinges break, the door could fly off and hit
the rotors.
Doing daily inspections catches that
problem before it occurs.
Here’s a question: Would you stake your
life right now on the condition of your work
platform doors? Remember, when you’re
standing high up on the aft work platform,
you’re only supported by two cables.
So take care of the small things now to
avoid the big problems later.
