72. ENGINE MAINTENANCE
Engine Power
Spark plugs should be the type recommended by the manufacturer. Adjusting a carburettor is a
specialised job and can have a large effect on the power developed by the engine.
Altitude can also affect the power available. When moving to a field with a different elevation it may be
necessary to retune the carburettor.
It is recommended that only a qualified person should tune the engine.
72.00.00 General
This aircraft is fitted with a Rotax 582 UL two cylinder, two-stroke water-cooled engine. The engine is
rated to 48.5 kW maximum take off power with full throttle at 5800 Rpm.
72.00.10 Maintenance and Overhaul
Other than any specific procedures specified elsewhere in this manual, detailed procedures for the
maintenance and overhaul of the Rotax 582 UL engine fitted to the XT 582 aircraft can be found in the
following documents:
- Rotax Operator Manual for Rotax Engine Type 582 Series
- Rotax Documentation CD
Documentation for Rotax engine s available at
www.rotax-aircraft-engines.com
The supplied manuals and documentation are supplemented by Rotax Service letters and Service
Bulletins as appropriate. The Rotax website should be periodically reviewed for these updates.
Overhaul of Rotax engines should be performed by a qualified Rotax service centre.
72.00.30 Radiator
If it is necessary to replace the radiator hoses it is important that the replacement hoses are identical to
that supplied with the aircraft. The engine coolant is circulated rapidly through the cooling system and
the fitting of hoses other than those supplied can increase flow resistance leading to excessive coolant
temperatures. Refer to the Rotax Maintenance Manual for detailed Radiator maintenance, and specific
fluids and replacement specifications.
