Presenting
Sbach Xtremeair 342
 |
Mission
|
Modern two seat aerobatic aircraft, you have the choice how to use it:
- Compete and exercise up to Unlimited competition acrobatics
- Enjoy to fly two people in style with speed and range
- Show a friend the wonders of speed and acrobatics
Equipment can range from “spartan-competition” to “luxury-leather” with high-end avionics, just ask us!
The aircraft will be certified under EASA CS-23 regulations. |
|
|
Structure
|
Fuselage shells, wing, all control surfaces and stabilizer are made of
high-tech carbon/honeycomb sandwich, manufactured in a wet layup method.
Surface protection is peformed by high quality acrylic paint.
Engine mount and control system is aircraft steel 1.7734.5
The whole airplane was designed using modern 3D-CAD, all of our tooling was
CNC-routed.
All composite parts are fabricated in precise female molds to secure perfect
symmetry and fit. |
|
|
Controls
|
Stick and rudder controls for both seats.
Aileron and elevator control are actuated via
carbon tubing.
Flettner-type elevator trim.
Hydraulic wheel brakes are actuated via toe pedals.
Engine (Throttle, Propeller and Mixture) are controlled via push-pull cables
and very cool quadrant.
|
|
|
Wing
|
Symmetrical wing, airfoil strake of own development for crisp snaps and high
cruise speeds.
For best possible safety the wing is a one piece double box main spar from
wing tip to wing tip.
Each aileron is hinged on 5 points, and is equipped with spades to reduce
control forces and enhance handling.
|
|
|
Empennage
|
Stabilizer and fin use the same symmetrical laminar flow airfoil.
All control surfaces can be easily removed for transportation and inspection
in about 2 hours with two people.
All control surfaces are statically balanced according to flutter evaluation
performed by Prof. Dr. Norbert Niedbal.
|
|
|
Fuselage
|
Fuselage has seating for 2 occupants, the Pilot in command uses the rear seat.
Canopy opens to the right hand side, an emergency jettison system is
installed.
The rudder pedals are adjustable.
The seat is equipped with a 5-point aerobatic harness system.
|
|
|
Landing Gear
|
The aircraft is a fixed gear taildragger.
The main gear struts are steel
spring type.
Tailwheel is mechanically linked to the rudder pedals, the wheel is solid
rubber, 125 x 50 mm.
Mainwheels are 5 x 5.00 tyre size with hydraulic brakes.

|
|
Engine
|
Either the Lycoming Thunderbolt AEIO 580 L1B5 or 540 variant are available.

|
Fuel system
|
All fuel cells are composite, protected and sealed with a special certified
tank sealer.
Aerobatic tank in forward fuselage, containing 50 Liters (13.2 US Gals.),
including a header tank with a flop tube to prevent fuel starvation in fun
attitudes.
For cross country flying each wing has a fuel cell near the root, containing
80 Liters (21.1 US Gals.) each.
Fuel selector switch shows „left“, „Acro“, „right“ and “Off“.
