Many Standard Cirrus owners wish to add a 5th strap to their security strap system. These documents from Schempp-Hirth were submitted by Colleen Koenig. They show how to add a bracket to the aft control stick bulkhead. This is not an official technical note, but rather seems to be written specifically for serial number 59.

Owners of 4-point Schroth security straps may find that their buckle will not take a 5th strap without modification. Tim Mara of Wings and Wheels knows all about the issues involved.
