UNUSUAL OR ABNORMAL GREASE
LEAKAGE OR VIBRATION DEMANDS
IMMEDIATE INSPECTION.
(1) Important Information
(a) A new or newly overhauled propeller may leak slightly
during the first several hours of operation. This leakage
may be caused by the seating of seals and O-rings,
and the slinging of lubricants used during assembly.
L eakage should cease within the first ten hours of
operation.
(b) Leakage that persists beyond the first ten hours of
operation on a new or newly overhauled propeller,
or occurs on a propeller that has been in service for
some time will require repair.
1 A determination should be made as to the
source of the leak. If the source of the leak is
the O-ring seal between the engine and the
propeller flange or a lubrication fitting, field
repair is permitted.
2 All other leakage repairs should be referred
to a certified propeller repair station with the
appropriate rating.
3 If abnormal grease leakage is detected, inspect
the propeller assembly using the Inspection
Procedure steps in this section.
