An example: why hasn't the
SSA pushed for ballistic parachutes which would have
saved many lives

The market, which buys gliders which the SSA does not, has shown a distinct
lack of interest in recovery chutes. I believe Schempp-Hirth offers a chute as
an option for some of its gliders. I wonder how many they have sold, or even if
interest warranted certifcation?

Because most gliders are made and certified in Europe any installation would
have to meet European Certification Standards. Several years ago Hanko
Streifeneder fitted a Discus with such a recovery parachute. He actually did
several in flight deployments. The certifying authorities decided that the
system had to be tested up to VNE. At some point Herr Streifeneder wisely
decided to stop flight testing. I think it was when the glider almost fell back
into the deploying parachute.

Having a recovery parachute on board is no guarantee that you are safe.

Has anyone tested the Sparrowhawk with a parachute deployment? What testing has
been done?

If you want a touring type motorglider with a rescue parachute check out the
Sinus or Virus from Pipistrel. There have been two in flight deployments of the
rescue parachute, with no serious injury to the occupants. That is real world
testing.
