| Subject: | Yak-52 elevator failure |
At the end of last year, the elevator actuators segment on a Russian Yak-52
failed, and the resulting crash was fatal.
The "sector" involved is the plate between the two elevator end plates,
underneath the vertical stabiliser. The elevator cables connect to the top
and bottom of this plate, and clearly if the plate fails all elevator
control is lost.
The current design is made from high tensile aluminium , and it is expected
that there will be a formal Service Bulletin requiring a change to steel.
In the meantime, all 52 owners are strongly recommended to remove this plate
and have it crack-tested.
If you follow this link,

photograph of the failed item from the crashed aircraft, as well as a
photograph showing the plate in place on a 52.
