CAUTION: INSTRUCTIONS AND PROCEDURES IN

A. Lubrication Intervals
(1) The propeller must be lubricated at (12) calendar months
or at 100 hour intervals, whichever occurs first.
NOTE 1: If annual operation is significantly less than 100
hours, calendar lubrication intervals should be
reduced to six months.
NOTE 2: If the aircraft is operated or stored under
adverse atmospheric conditions, e.g., high
humidity, salt air, calendar lubrication intervals
should be reduced to six months.
(2) Owners of high use aircraft may wish to extend their
lubrication intervals. Lubrication interval may be gradually
extended after evaluation of previous propeller overhauls,
with regard to bearing wear and internal corrosion.
(3) New or newly overhauled propellers should be lubricated
after the first one or two hours of operation, because
centrifugal loads will pack and redistribute grease.
NOTE: The purchaser of a new aircraft should check
the propeller logbook to verify whether the
propeller was lubricated by the manufacturer
during flight testing. If it was not, the propeller
should be serviced at earliest convenience.
