Inspection In Extreme Climatic Conditions - Rotax 912 Series Maintenance Manual

3.2)

Inspection in extreme climatic conditions

General note
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 adjustment of the carburetor jetting and of the cooling system. To
do this, it is necessary to contact the aircraft manufacturer and an autho-
rized ROTAX distributor.
3.3) Returning engine to service after influence by fire
General note
An engine after influence by fire must be inspected, repaired or over-
hauled in accordance with the BRP-Powertrain instructions for continued
airworthiness. See therefore affected Maintenance Manual, latest issue.
Inspection
- Inspect all systems for correct functioning.
NOTE:
If an engine was influenced by fire, first a visual inspection of all parts has
to be done and then a hardeness test of all mechanical parts must be per-
formed (e. g.: crankcase, cylinder, cylinder heads etc.).
In most cases an overhaul is necessary, in this regard send the engine
without delay to an authorized ROTAX overhaul facility for inspection.
