MAINTENANCE MANUAL LINE
• gearbox • valve train system
• engine suspension frame • exhaust system
• fuel system • lubrication system
• cylinder unit • start system
In most cases an overhaul is necessary, in this regard the engine has to be overhauled ac-
cording to the current Overhaul Manual (OHM) for the respective engine type. Overhaul
Manual (OHM) and its appendix is available for any appropriately rated person or entity on
request and by following the standards of the original manufacturer.
If an engine was submerged into water, all electrical components
(e. g.: electric fuel pumps, ignition coils, stators, spark plugs, spark plug connectors, FUSE
BOX, sensors, ECU, wiring harness) must be replaced.
NOTE
Discoloration or corrosion are signs of submerging in water.
INSPECTION IN EXTREME CLIMATIC CONDITIONS
General note
NOTICE
Every 25 hr. checks of air filter, coolant radiator and oil cooler are necessary.
Flying in deserts or areas with heavily contaminated or dusty air causes increased wear
on all components. For this reason, shorter maintenance intervals are recommended.
Flying in areas with extreme climatic conditions or in extreme altitudes requires adjust-
ment of the cooling system. To do this, it is necessary to contact the aircraft manufacturer
and an authorized ROTAX® Authorized Distributor or their independent Service Center.
DIMINISHED FUNCTIONAL CAPABILITY OF EMS
General note
NOTE
The diminished functional capability of EMS must be entered by the pilot into the
engine log book, stating duration extent of diminished functional capability and all
pertinent details.
• Perform engine inspection.
Read out the ECU data memory and check the data for details of diminished functional ca-
pability. Perform the corresponding inspections/repairs depending on the functional de-
fects found.
