f you have the unit maintenance aerial recovery kit (UMARK), there could be a
manufacturing defect in the slings, NSN 3940-01-538-5218, P/N 94H520-2.
Users sometimes refer to this sling as the 30-ft heavyweight black/white sling
with bridle.
All units that have a UMARK kit need to identify, inspect, and purge all defective
slings from their kits
now!
The problem with the sling is that the bridle was placed at the wrong end of the
sling by the manufacturer. The sling has two distinct ends. On the “single-eyed” end,
you have one eyelet. On the “double-eyed” end, you have two eyelets. The bridle of
a correctly manufactured sling should be approximately seven feet from the double-
eyed end. If the bridle is in
any other
location on the sling, it is defective.
When
rigging
an
aircraft
for recovery, the double-eye
end of the sling is
ALWAYS
placed on the side of/pointing
to the aircraft being recovered.
If a defective sling is used, it
will cause a severe nose down
attitude of the aircraft being
recovered and can cause further
damage to the aircraft when it
is set down upon completion of
the recovery.
If you have a defective sling,
check
out
General Aviation
Safety Action Message (GEN-
11-ASAM-01) for inspection
criteria
and
how
to
get
a
replacement sling.
