Break-In Flight Operation
•
Perform normal pre-flight and run-up in
accordance with
Operation Manual, SVIOM01 (remember to
cycle controllable pitch prop to only a 100
RPM drop). Keep ground runs to a
minimum.
•
Conduct normal take-off at full power, full
rich mixture, to a safe altitude.
NOTE: In certain geographic locations and
weather conditions (eg; high density
altitudes) "Full Rich" operation may not
be practical. In this event, substitute the
requirement of "Full Rich" as discussed
in this chapter with the "richest practical
setting".
NOTE: Verify the crankcase breather and vent
lines are correctly
positioned. Excessive oil discharge
through the breather can often be
directly related to an improperly installed
or restricted breather line.
•
Maintain shallow climb. Use caution to not
overheat the cylinders. Should overheating
occur, reduce power and adjust mixture
appropriately.
•
Monitor RPM, oil pressure, oil temperature
and cylinder temperature.

After landing, check again for any fuel
and/or oil leaks, or other discrepancies, and
repair as required.
Post Break-In Procedures
•
After break-in, drain all mineral oil. Examine
this oil for foreign matter or metal particle
content.
•
Fill with ashless dispersant oil of the
appropriate grade for the expected normal
operating
temperature.
