Don’t wait.
If you do, it could mean some broken bones, if you slip and fall off
your bird while performing maintenance. Fall off the top of your Chinook, and you
could die!
The new Mil Spec for finishing walkways is A-A-59166. Make a note until the
TMs are updated. If you need some black finish, NSN 8010-00-641-0247 brings
you one gallon and NSN 8010-00-142-6525 brings one quart.

e careful, mechanics, when you remove your Black Hawk’s T-700-GE–700
series engine oil cap to add oil.
When the cap and O-ring stick, some mechanics muscle off the cap. Instead, they
should twist the cap back and forth to loosen it and then ease the cap off.
The cap has a short cable that’s
attached to a metal tang on the screen. If
you use force to pop loose the cap, you
can jerk the cable and snap off the metal
tang on the screen assembly. That screen
keeps FOD from entering the oil tank
while the cap is removed.
Pulling and tugging too hard leads to
replacing the oil cap and filler assembly,
NSN 5340-01-318-0077, for about $330.
A sticking cap is no fun to remove—but
it’s even less fun to replace the assembly!

our Chinook’s high-traffic, non-skid walkway areas take a beating from boots that
wear off the non-skid material. Grease and oil and dirt left on exposed rivets makes
walking on worn-out walkways dangerously slippery.
So pay attention, repairers, and be careful when walking on places like the ramp
and on top of your bird. Inspect the walkways for wear. If you notice shiny rivet
heads through the non-skid material, resurface the walkways like it says in Task 2-
356 of TM 55-1520-240-23-2 and paragraph 6-12 of TM 55-1500-345-12.
buddy, you didn’t
believe me when I
told ya to
go easy
on my engine oil cap.
holy cow!
this walkway is
slippery as

Forcing cap off will
