CAUTION:
TO PREVENT DAMAGE TO THE BLADE
AND BLADE PAINT, WRAP THE BLADE
SHANKS IN SEVERAL LAYERS OF
MASKING OR DUCT TAPE BEFORE
REMOVING THE SPINNER DOME (IF
INSTALLED).
(3) Spinner dome removal (if installed)
(a) Remove the screws and washers that secure the
spinner to the spinner bulkhead.
(b) Remove the spinner dome.
CAUTION:
PERFORM A VISUAL INSPECTION
WITHOUT CLEANING THE PARTS. A TIGHT
CRACK IS OFTEN EVIDENT BECAUSE OF
TRACES OF GREASE EMANATING FROM
THE CRACK. CLEANING CAN REMOVE
SUCH EVIDENCE AND MAKE A CRACK
VIRTUALLY IMPOSSIBLE TO SEE.
(4) Perform a visual inspection of the hub, blade clamps
and blades to locate the origin of leakage. If the origin
of the grease leakage is determined to be a noncritical
part, such as an O-ring, gasket or sealant, repairs can be
accomplished during scheduled maintenance as long as
flight safety is not compromised.
(5) If cracks are suspected, perform additional inspections
before further flight (by qualified personnel at an
appropriately licensed propeller repair station) to
verify the condition. Such inspections typically include
disassembly of the propeller followed by inspection of
parts, using nondestructive methods in accordance with
published procedures.
(6) If cracks or failing components are found, these parts
must be replaced before further flight. Report such
occurrences to airworthiness authorities and to Hartzell
Propeller Inc. Product Support.
