Materials used for the airframe
The airframe is made of high-quality composite materials which permit excellent
aerodynamic characteristics to be achieved at an efficient structural weight.
Due to the strict weight regulations for light sport aircraft, reinforced carbon and
aramide fiber materials are used in the more advanced designs.
Due to the complex nature of composite materials and the necessary knowledge in
the lay-up of a specific structure, repair work on the composite airframe may only be
undertaken by a qualified facility. For this reason, only general information about the
materials used is given in this handbook. Should the aircraft structure be damaged,
detailed information must be requested from the manufacturer.
