Dear Editor,
Recently our
UH-1
helicopters ±eceived the Wire Strike
Protection System. The lower cutter blade poses a safety
hazard to anyone working under the bird's nose. We made an
inexpensive protective cover that works fine. Kiowa mechs
can use it, too² For each aircraft you need:

Insert the hose into the pitot tube cover. Then slip the
hOse onto the end of the wire cutter as far as possible. Tie
the drawstring to hold the c³ver in plac´² The red streamer
aleµs mechanics that the cutter blade is there, and the hose
w¶L cushion any part of the body that hits the blade. If the
end of the hose stretches after repeated use, just reverse it²
