61.10.00 Propeller Service
61.10.10 Inspection
The intervals at which the propeller must be
removed for inspection are specified in the
Maintenance Schedule.
With the propeller removed from the aircraft and
each of the components separated the blades and
boss should be inspected for the sort of damage
described below paying particular attention to those
areas which are not visible when the propeller is installed. In addition, the following inspections should
be carried out:-
•
Bolt holes should be examined for out of round, rough edges, and cracks radiating into the boss.
•
Check the whole surface of the hub especially in all areas where there are corners. Make sure
the surfaces are clean and there is good lighting. A magnifying glass will aid close inspection.
•
Boss faces should be examined for damage where they have been in contact with the hub
flanges, particularly at the circumference of the flanges.
•
The centre bore should be examined for cracks and delamination of the plies.
•
The mounting hub should be examined for corrosion, cracks, correct fit on the crankshaft, and
for condition of the attachment bolts and nuts.
•
Take note of any sharp nicks, cuts or scratches, as these are stress points from which further
problems may occur. Act on them if required. Replace the LE Tape if damaged. Do not operate
without LE tape.
•
Inspect the propeller and hub in the area around where the prop exits the hub.
•
Inspect the bolts, replace if any wear or damage is present.
WARNING
IF THE ENGINE IS TO BE ROTATED AT ANY TIME, IT SHOULD ONLY BE ROTATED IN THE
SAME SENSE (DIRECTION) AS IT RUNS.
WARNING
WHEN WORKING ON THE PROPELLER
