Nice to be concerned, But there's nothing wrong with a "mod" done properly, to
a set standard.
As far as safety is concerned, keeping the FOD out of the aircraft & regular, good
maintenance will go a long way... (amongst other things)

Blitz,
Sorry to hear about the gear colllapse, but happy it didn't occur on T/O
or landing. I found something similar with a worn 'over center" part
last Fall. During the December conditional inspection we found quite a
few gear parts that were just worn and needed to be replaced. Several
others would "probably" make it another year before replacement.
Fortunately, Doug Sapp had a new set of gear available that I could
afford for the same price as replacing the old parts with an exchange.
I dusted the wallet off and did it. Now I'm really glad I did. Point
being, the fact that we all work together to help each other see
alternative solutions is one of the YAK communities greatest strengths.
Also, the gear retraction used to be rather "violent" (it scared the
mechanic.) Thanks to the YAK resources of Doug and Dennis, he was
reassured that this was due to the desire of some airshow pilots to
remove the pressure relief ports for a snappier gear retraction which
just looks better. (You guys know this, but I didn't, and there was no
way we would have descerned this from the Chinese manuals without
spending hours guessing.) As financially painful as owning any aircraft
can be, all I can say is that people outside of the YAK community are
envious of our relatively low costs, fun factor, resources and
camaradie.

Gang,
I have had several calls from CJ drivers who don't fully undertand just
which part failed in Blitz's aircraft, so here is the chapter and verse: It
is shown in IPB vol #1, the drawing is on page167, fig 4-21. The part which
broke is item #1, p/n H2-4120-03. (-03R/H and -03L/H).
When checking this part on your aircraft make sure you check to see that the
bearings are tight, and that the gear actuator conforms with the setting
called out in the manual. While we do not know for sure what caused this
failure, sloppy bearings and/or a incorrectly adjusted actuator ram just
might cause such a failure,
Hope this helps clear things up.

Always Yakin,
Doug Sapp

First mechanical gear collapse I have seen on a CJ in 13 years not attriuted to
"dummy damage". Could hydrogen embrittlement have played a role as this is an
old-fashioned chromed part?
