echanics, rotating Black Hawk blades may be a simple job, but it isn’t as cut-and-dry as
you may think.
Throwing a rope over the blades to turn them is OK, but keep the rope off the trim tab.
The trim tab is thin and light. Throwing a rope over the blade’s trim tab and pulling can
bend or break the tab. A damaged trim tab knocks the blades out of track.
Not only will the trim tab need repair but the rotor blades will need retracking and
rebalancing.
Keep the rope off the trim tab when rotating blades. Your rotor shop will appreciate it.

echanics, there are two new torque wrenches in the supply system for use on your
Chinook. These wrenches will replace the current wrenches now being used.
Order torque wrench, NSN 4920-01-546-0471, for the forward and aft transmission
mount bolts. The new wrench replaces NSN 4920-01-232-7706.
Order torque wrench, NSN 5120-01-563-5988, for the forward and aft rotor head
retaining nuts. This new wrench replaces NSN 5120-01-136-2084.
Both wrenches have digital readouts, weigh much less than the current wrenches
and cost less, too.
