7.9 Occupant restraint Harness
Both front and rear seats are fitted with a 3-point restraint harness system. The shoulder inertia reel
system is fitted to the mast and requires attachment on the male section of the lap belt during lap belt
fastening (see photo).
When flying the trike solo it is important to fasten the rear seat belt to prevent contact with hot engine
components in flight.

The propeller pitch setting and checking procedure is outlined in the Base Maintenance Manual. The
pitch setting is determined as a part of certification of the aircraft. Settings outside this specification have
an unknown effect on aircraft performance, and are not approved. Propeller pitch setting effects engine
rpm. If the engine exceeds its rpm limits, check to see that the propeller pitch is set correctly.
