SECTION 8
Aircraft Operating Instructions Edge XT912
HANDLING & MAINTENANCE
January 2014
Issue 2.4
Page 105
Airborne Windsports have decided to change back to conventional coolant based on ethylene glycol
with 50% water content for aircraft with base serial number commencing XT-912-0445, March 11, 2014
until further notice.
Owners and maintainers of Airborne Windsports 912 powered aircraft are not required to change
coolant, but be aware that different coolants are available, and that mixing of coolants must not occur.
8.8 Tyre Inflation
The recommended tyre inflation pressures are 13 to 17 PSI (19 to 117kPa) for both the front and rear
tyres. When checking the tyre pressures the opportunity should be taken to examine the tyres for wear,
cuts, bruises, slippage and other defects.
8.9 Shock Struts
8.9.1
Rear Shocks
The rear shocks are pressurised to 580 PSI using a schrader valve system. A special pump will be
necessary to repressurise the rear shocks to the correct setting. There should be no reason why the
rear shock would need to be reinflated, and if they do then a proper investigation of the cause should be
undertaken.
8.9.2
Front Shocks
The front shocks should be inflated to 50 psi for each reservoir. The top should be inflated first. Turn the
rebound damper fully clockwise, and then anticlockwise for twelve clicks.
8.10 Brake System
A rear wheel disk brake system is used on the aircraft. Depressing the brake lever on the left hand side
of the front footrest actuates the brake. On aerotow equipped trikes the aerotow release is the lever on
the top left, painted yellow. A brake lever lock is provided. To engage, depress foot lever and raise
locking lever by hand. To disengage, depress the foot lever.
Use wheel chocks when leaving the disk brake equipped aircraft unattended for a period of time.
8.10.1
Brake System Maintenance
Details of brake bleeding and other required maintenance of the braking system can be found in section
32.40.00 in the maintenance manual
8.11 Parking and Ground Handling
Parking and ground handling information can be located in section 4.
8.12 Circuit Breaker and Fuses
The fuses for the electrical equipment are located in two positions.
1. The Lynx intercom system has a 1.5A fuse screwed into the side of the box where the
headsets and push to talk cables are plugged in.
2. The power supply cables for the radio are protected at the rear of the aircraft with inline fuses
which terminate at the right hand side of the mast block. A 5A fuse is to be used for the radio and
intercom power supply. The fuse holder is marked with the correct Current rating for the fuse.
WARNING
SPECIALISED PUMPS MUST BE USED FOR THE AIR SHOCKS – PRESSURES UP TO 600 PSI
EXIST.
