Seat Belt Preparation - Pipistrel Sinus Build Manual

Drill the holes in the firewall for the rudder pedals. These must also go through on the

same angle as the cockpit floor. Note that these holes must go through two layers of
fiberglass thus, if they are done at the wrong angle they will come out the floor of the
fuselage and not in the correct position

Seat belt preparation

The seat belts have outer anchoring positions which have metal inserts embedded in the

fiberglass. Prepare them by tapping metric 8mm. Be sure not to tap he holes too deep
or you will go through the outer layer of the plane and cause major damage. The factory
uses an electric drill for the tapping, but they recommend that the kit builder should do
this procedure by hand.
