Schliecher introduced TN4 in 1969. This changed the Type Certificate to
allow the glider to be used for Semi aerobatic flying.
On the Schliecher web site, if you go to TN/AD's then scroll down to K13
and then to TN4 it shows the TN and it is down loadable. There is also an
overview list of all TN's issued.

I started gliding 15 yrs ago and the club had and still has 2x K13's. They
are used for training in all aspects of glider flying, including
semi-aerobatic manouvers.
Great fun.

We are examining the Type Certiifcate for the K13. The original indicates

in 1967 Schleicher issued an AD approving semi aerobatics and spins, and
printed a modified page 22 to the flight manual. Does this automatically
modify the type certificate? Is there some authority I am not aware of?

I can also report that the K-13 is an excellent spin trainer, having
received all of my instruction in this model in the 1980's. Standard
instruction in our club at the time required a student to experience
spin entry from several different attitudes as well as recovery from a
fully developed spin after at least two turns! Our club was run by
folks, including ex-pat Germans, who were sticklers in observing
rules, so it is inconceivable that the K-13 was not certified for
these manoevers.

Local certification should permit semi-aerobatics, but you should
check this. As these gliders are now rather old, I would also
suggest checking the aircraft thoroughly for any possible weakness or
corrosion. There have been a few airframe issues over the years that
I am aware of.
