7.5 

Landing gear system 

BRISTELL B 23 airplane landing gear is a three-wheel fixed design, that 
consists of the main landing gear and the nose landing gear. The nose 
landing gear is steerable. The main landing gear wheels are equipped 
with hydraulic disc brakes. 

7.5.1 

Main landing gear 

The main landing gear consists of the composite landing gear legs, 
wheel axle and wheels equipped with disc brakes. The landing gear legs 
are inserted in the gear channel under the seats, where they are 
attached using two bolts and a stirrup. Wheels are equipped with 
tubeless tires. The nominal tyre pressure of the main gear tires is 2.1bar. 

7.5.2 

Nose landing gear 

The nose landing gear is steerable. It consists of a welded steel leg, a 
steerable wheel fork, a shock absorber (spring and oil damper) and the 
nose wheel itself. The landing gear is attached to the brackets installed in 
the nose gear channel located between engine bulkhead and the main 
wing spar. The wheel is equipped with tubeless tires. The nominal tyre 
pressure of the nose gear tire is 1.8bar. 

7.5.3 

Wheel brakes 

The airplane is equipped with individual hydraulic disc brakes system for 
the main landing gear wheels. Brake system consists of the brake pedals 
(foot tip part of rudder control pedals), brake pumps, hoses for brake fluid 
supply, brake callipers and brake pads. By pressing pedals, brake pumps 
are compressed and pressure is generated in the brake circuit and the 
callipers pushes the brake pads onto the brake discs. Braking pressure 
can be controlled via brake pedal force. 

The airplane is equipped with a hydraulic manually controlled parking 
brake. It is activated by pressing the brake pedals and pulling the park 
brake control in the instrument panel. 

7.5.4 

Wheel fairings 

The airplane is equipped with composite wheel fairings that decrease 
drag and improve aerodynamic properties of the airplane. The wheel 
fairings are installed onto the brackets by bolts. 

NOTE: 

Operation without wheel fairings is not approved
