(9) For an unfeathering accumulator, check the air pressure.
(a) For a Hartzell Propeller Inc. unfeathering
accumulator, check the air pressure every 100 hours
or once a month, whichever comes first.
1 For the correct air pressure, refer to Table 6-11.
2 For procedures to recharge the unfeathering
accumulator, refer to the section "Unfeathering
Accumulator Air Charge" in the Maintenance
Practices chapter of this manual.

or there is engine oil leaking from the air valve,
a faulty seal in the accumulator should be
considered. An inspection to verify the condition

accumulator, refer to the manufacturer's published
data for inspection and check requirements.
