It seems the life limit was promulgated in 2004. Charming.
Most of those would have been manufactured before
Ceaucescu and wife met their thoroughly deserved
ends, at a time when the company was owned by the Romanian government.
The FAA clearly thinks there were no engineering
reasons to back this life limit with an AD. Pity
the GFA/CASA wasn't smart enough to do the same.
This raises the possibility that a company could
at any time issue a life limiting bulletin
because, for example, it is on the market to be
sold and a potential buyer is worried about the
liability tail of the company's manufacturing
history so the simple solution is to ground
all their aircraft over a certain age.

Something that was recently brought up...
 The following response dated 16 October from
the FAA to the Soaring Society of America's
government liaison, regarding the service life
of the IS-28B2 indicates the 30-year limit is void in their eyes.
