| Subject: | Yak-52 elevator failure |
Trawling the website of Yak UK reveals this to be a well known gotcha.
http://www.yakuk.com/2000-004.doc
MPD: 2000-004
Subject: Crack in elevator control system pulley.
Applicability: Yakovlev/ Aerostar or a SA Y B AK 52 aircraft.
Reason: A 19 mm crack has been discovered in the elevator actuation part
number 5251 or 00-80-3 (referred to as "lever" in the Romanian parts
catalogue). The failure of this component could result in loss of the
elevator control.
Compliance: Within 50 hours from the effective date of this MPD, inspect
elevator actuation pulley parts number 525100-80-34 cracking on its
periphery below the attachment for the balance weight bracket, at the point
where the section reduces from a 10 mm to 7 mm. Inspect using dye penetrant
techniques. if the component is cracked, replace it before Further Flight.
Repeat this inspection annually at renewal of the permit to fly.

Interesting!
How much weight is attached to this part? And for what purpose?

Well, the part is cracking on the upper side ... would it be due to aggressive
pull back forces on the stick?

Possibly. The crack is originating at the section change where loads would
tend to concentrate but it may also be subject to bending loads from the
balance weight attached to the upper, heavier, section.
Possibly rudder induced transverse loading?
I don't understand the use of a balance weight in this location.

| Subject: | CJ6 Shimmy damper problems |
I just done some high speed taxi runs in my cj6 today and have a few problems.
First thing is that i raise the the nose of the plane then put it down again and
i have got massive amounts of shimmy.
This was a brand new shimmy damper i bought and fitted as well.
Is there a special way to set them up?
Thanks Daniel
