he preferred AMCOM method for raising and lowering Chinook rotor blades
uses a hangar crane. It's an awkward job and requires up to three persons.
But some units simplify the job and reduce the manpower required by making
and using a rotor blade stand. It lifts, lowers and holds the blade in place while
the pitch change links are adjusted.
If your commander OKs using the stand, here's what you need to make it.
Here’s how to put the stand together:
When you use the stand, make sure
you put the legs of the blade stand
ONLY on the reinforced seams of the
fuselage so they don’t dent or tear the
bird’s skin.
Never tighten the hardware attach-
ing the blade support to the vertical
beam. The blade support must be able
to tilt to fit the angle of the rotor blade.
