Dip Davis Cowl Latch STC for
Cessna 120/140/140A/170/170A/170B
The W. D. Davis CWR-1 rivet kit replaces the S-43 fabric retaining clips in the
wing rib flange with a large bearing area head "Pop" riet. The kit consists of
1000 rivets and enough self-adhesive reinforcing tape to do both wings on a
Cessna 120/140 or 170.
The wing clips worked well for the first and probably second time the wings
were covered, but over the years the holes may have gotten enlarged to the point
that the clips no longer fit snugly and canwork their way right through the
surface tapes in some cases. If you need to replace all of the clips you
will be faces with an expense of over four dollars even with a 40% discount.
We charge $200, postpaid, for the entire kit, including all the required paperwork.
Don't be intimidated by the rivet removal preocedure in the installation
instrutions. These rivets have aluminum mandrels and are easliy drilled
out without driving the mandrel out first. The aluminum mandrel also
eliminates the possibility of dissimilar metal corrosion which is present
in steel mandrels.
