Sleeves? I can't help. Pins? Aircraft Spruce

Thanks for all the links, guys, but these are not the spec that is
called=
for in this AD. The glider in question is a Bolkow Phoebus, but I
believe=
this AD also applies to the Standard Cirrus, as well as some others
(corre=
ct me if I'm wrong). It specifically states the clip must be 1.2mm
diamete=
r wire, and gives a picture of the clip going across the push rod. In
this=
particular application, the push rod is only about 1/2" diameter, so a
cli=
p that is 1.5" long will stick out the sides too far and hang up on the
sur=
rounding structures. Here's a link to the AD:

Look particularly at the PDF link "13 94_001 L`Hotellier
Verschluesse.pdf=
(94,4 kB)". =20

It gives pictures and dimensions of the clip needed. It specifically

number
1=
473 931, but neither of these part numbers come up with anything

copies of the AD when a Google search is done. I can not find a

fo=
r these specific parts.

More specifically, these connections are for aileron and spoiler push
rods

that come through holes in the wing root rib. If the clips stick out too
f=
ar, they will snag on the edges of the holes in the wing root rib and
cause=
the control surfaces to hang up and not move properly. Obviously,

I think that you are getting the various locking devices confused! The
AD is issued by LBA - Google LBA 193-001/3 for the current version.
There are various locking methods to choose from - safety pins, Uerling
sleeves, LS locking sleeves, Schempp-Hirth clips, Wedekind sleeves are
all mentioned in the AD.

The L'Hotellier and Ford safety pins are very small and simply go through
the connector lock plate as shown on the second page of the Lindner
document. They do not go round the push rods or stick out to foul the
holes in the root rib.
