osing your footing on the Chinook’s ramp area happens for two reasons.
One reason is that boots going up and down the ramp wear off the non-skid
coating. That exposes the bare flooring and makes the ramp’s walkway slippery
and dangerous.
The second reason is an accumulation of transmission oil and/or hydraulic fluid
during maintenance or from leakage from the many lubrication lines and hydraulic
components in the ramp area. That can lead to slips and falls.
So pay attention mechanics and
crew members and be careful when
walking on the ramp. If you notice
shiny areas through the non-skid
coating, maybe it’s time to resurface.
If the non-skid coating is OK, and
you notice a oily area, use some
elbow grease and clean it up.
Whether it’s worn out non-skid
coating or oily build-up,
don’t wait!
Fix the problem unless you like
dealing with broken bones.
Walking on areas of your bird that have slippery walkways puts you in harm’s
way. So take the time and let your ±ngers do the walking through the TM pages on
caring for your aircraft walkways.
Check out paragraph 6-12 of TM 55-1500-345-12 for the details.

echanics, night maintenance on your Chinook calls for extra attention to detail.
Without daylight, it’s easy to leave items in the wrong place.
When performing night maintenance, pay particular attention to the ramp side areas
prior to raising the ramp. Make sure nothing is left on the ramp sides that may put the
ramp or other equipment in harm’s way. Pick up anything that is loose and put it away.
Oil cans, ammo cans, and even combat helmets sometimes get left on the ramp sides.
If the area is not picked up, the ramp and what-ever is placed on the ramp sides will get
crushed or destroyed when the ramp closes.
The ramp side areas are
just thin sheet metal, so
anything that gets caught
there will punch a hole
through the ramp and
likely destroy a portion
of the airframe. It will
deFnitely destroy whatever
is left on the ramp side.
Eyeball the area when
nighttime maintenance
is complete to avoid
the crushing problem of
airframe repair.
