7. Oil Servicing Schedule

NOTICE: While compliance with the oil change schedule and inspections in Table 1 of this
Service Bulletin is mandatory, in special circumstances, the oil change intervals in
Table 1 can be extended by not more than 5 hours while on route to a place where the
oil change can be done (on engines using aviation fuel).
Initial oil change and oil filter replacement of any
new, rebuilt, or overhauled engine, or engine
returned to service after storage
&
Oil suction screen cleaning/inspection
Routine oil change and oil filter replacement (after
initial 25-hour oil change and oil filter replacement)
&
Oil suction screen cleaning/inspection
* Oil change intervals must not exceed 4 months regardless of operating hours and especially if the
aircraft has not been flown for at least 25 hours in a 4-month period. More frequent oil changes are
recommended if the engine has been exposed to volcanic ash, particulate, sand, dust, debris,
extreme weather conditions, or salt spray in coastal environments.
** If oil consumption does not stabilize, identify and correct the cause and repeat this procedure.
