Servicing
4.1
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. Mixture of various brands and types of materials is undesirable and should
be avoided wherever possible. Specified lubricants will meet requirements for extreme
hot or cold temperature operations. Use of substitutes or other lubricants may cause
malfunction, or excessive wear.

Replenishing
4.2.1
Fuel System Replenishment
Fuel Specification
The Skypper has a single fuel tank, capacity 55 L. Fill to the neck of the fuel entrance.
The Rotax 582 engine uses a mixture of oil and gas for lubrification. Refer to the Rotax
manual section for engine fuel mixture specifications that apply to the region where the
aircraft is being flown.
Due to higher lead content in AVGAS, the wear of the valve seats and deposits in
the combustion chamber will increase. Therefore, use AVGAS only 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.
4.2.2
Fuel Sampling/Draining
There is a hose and drain cock on the base of the fuel tank behind the back seat, 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 from 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 visually for any other
contaminants.
If the fuel has been sitting for an extended period without use it may be advisable to
replace it with fresh fuel.
