12. SERVICING
12.00.00 General
This chapter provides servicing procedures necessary to replenish or service the aircraft and its
equipment as required.
The operational integrity of the aircraft systems can be seriously impaired if contaminated fuel, oil, fluids
and lubricants are used or if they do not meet the required specifications. Mixtures of various brands
and types of materials is undesirable and should be avoided wherever possible even though the use of
such mixtures may be technically acceptable. Specified lubricants will meet requirements for extreme
hot or cold temperature operations. Use of substitutes or other lubricants may cause malfunction, or
excessive wear.
12.10.00 Replenishing
12.10.10 Fuel System Replenishment
Fuel Specification
The XT has a single fuel tank, capacity 70 L.
NOTE
On manufacture the fuel tank has 64 Litre capacity and is known to expand within the first month of use
to the specified 70 Litre capacity, take note of this fact when planning flight times.
When the tank is being filled there may be a slight pressure differential between the sides of the tank,
causing the fuel cap side to fill slightly faster than the other side. Allow time for the breather valves to
equalise the pressure to allow complete filling and, check that both sides are sufficiently full. Fill to the
neck of the fuel entrance.
FUEL
Preferred Fuel Type
En228 Premium/Regular. Super grade gasoline, lead free, min
RON 90
Optional Fuel Type
AVGAS (see note)
Figure 16 Fuel Specifications
NOTE
Due to higher lead content in AVGAS deposits in the combustion chamber will increase. Therefore, use
AVGAS only if you encounter problems with vapour lock or if the other fuel types are not available.
Special instructions and service intervals are specified when using Avgas. If Avgas is used the Rotax
web site should be referenced for maintenance requirements. See Rotax service information 18-UL-97-
D/E, which outlines special instructions regarding the oil system when using AVGAS.
Fuel Sampling/Draining
There is a draincock on the base of the fuel tank at the left hand side, which may be used to check the
quality of the fuel, and to drain fuel if necessary, it is especially important to remove any water form the
system.
Checking the fuel:
The fuel is checked for water and contaminants by draining a sample of the fuel into a clear glass
container. Once a sample has been taken the quality of the fuel can be checked by looking for any
water at the bottom of the glass, and checking for any other visual contaminants.
If the fuel has been sitting for an extended period without use it may be advisable to replace it with
fresh fuel.
