BRP ROTAX 916 i A Series User Manual

8.1) Engine preservation and storage
General
Environmental corrosion (on the external surfaces) is a natu-
rally occurring process which can inevitably affect the continued
airworthiness of the engine, engine mounted components and
accessories. Susceptibility to corrosion is influenced by a num-
ber of factors, including but not limited to, geographical location,
season and usage. All general preventive (technical) measures,
identification, control and treatment of corrosive attack on air-
craft structures and engine materials has to be carried out in ac-
cordance with Advisory Circular AC 43-4B from FAA and also in
accordance with the information of the aircraft manufacturer
´s Instruction for Continued Airworthiness. Furthermore the
preservation procedures for stored and inactive aircraft (en-
gines) provides an effective means for combating and minimiz-
ing the corrosion condition and should be adhered to.
Advisory Circular AC 43-4B: This advisory circular (AC) is a
summary of the current available data regarding identification
and treatment of corrosive attack on aircraft structures and en-
gine materials. Corrosion inspection frequency, corrosion identi-
fication, and especially corrosion treatment continues to be the
responsibility of the operator. These inspections should be ac-
complished per this AC, the manufacturer’s recommendations,
or the operator’s own maintenance program. The procedures in
this AC are an acceptable means, but not the only acceptable
means, of corrosion treatment. The information in this AC is ap-
plicable to aircraft for which the manufacturer has not published
corrosion control information.
m WARNING
Risk of burns and scalds! Hot engine parts!
Conduct checks on cold engine only!
Due to the special material of the cylinder wall, there is no need
for extra protection against corrosion for the ROTAX® aircraft
engines. At extreme climatic conditions and for long out of serv-
ice periods we recommends the following to protect the valve
guides against corrosion:
Step Procedure
1 Operate the engine until the temperatures have stabilized
for a period of 5 min (engine oil temperature between 50 to
70 °C (122 to 160 °F).
2 Shut-off engine.
3 Allow the engine to cool down.
