queezing your foot into an old boot can be a tough job. Removing or installing a
tail rotor boot on a Black Hawk tail rotor can be a tough job, too, with the current
boot tool.
The current tool scrapes and scars
the blade as you slide the boot down
the blade. Modifying the tool shown
on Page H-327 of TM 1-1520-237-23-
11 to add clearance between the blade
and the boot tool is an easy way to
avoid tail rotor blade damage.
To make the modified tool, you
need a 23-in piece of 3/8-in rolled
steel rod. Measure six inches from
each end and bend the rod 90°.
Measure four inches from each end
and bend 90° as shown in the illustra-
tion to the right.
To install the rubber boot on the
new tool, just slip it over the
4-in sections of the tool. Follow the
procedures in Para 5-4-42 and slide
the tail rotor boot down the blade to
its position and remove the tool.

ilots, crew chiefs, maintenance personnel,
and flight crews, listen up! Closing Black Hawk
cockpit doors wrong causes cracks around the
door and handle mechanism.
The proper way to close cockpit doors is to
grasp the handle and slightly push it to make
the door lock.
If you’ve been locking the door handle latch-
es from the inside by slapping or punching the
door handle latch mechanism, then
Stop!
Slapping,
punching or
otherwise
hitting
the
door handle
from the in-
side to lock
or secure the
cockpit doors
causes cracks
or holes.
Once a crack is too big, the door is consid-
ered unserviceable. Then your bird is NMC
until the door is replaced or repaired.
Slapping, punching or hitting may be a quick
and easy way to follow the DOOR SECURE
step in the TM checklist, but it’s not good for
the cockpit doors.
