CATTO PROPELLER

(1) TROUBLESHOOTING

If the propeller-engine combination feels rough in flight;
(a) Check that the mounting face of the propeller is tight against the engine flange
and check the blade track.
(b) Verify that the attaching bolts have reached their required torque and have not
bottomed out of the threads.
(c) Remove the propeller, rotate it 180 degrees on the engine crankshaft flange, and
re-install. Again, check the blade track.
(d) If roughness or vibration is still present, dynamic propeller balancing may be
required.

(2) REMOVAL

(a) Remove the spinner.
(b) Cut and remove the safety wire from the propeller bolts.
(c) Remove the propeller bolts. Assistance may be needed to hold the propeller and
aft spinner bulkhead.

(3) INSPECTION

(a) Examine the propeller blades for corrosion, cracks, nicks, or dents beyond the
permissible limits. These limits will be found in the propeller manufacturer's
service manuals. If the propeller is unserviceable, replace it with a new one and
return the damaged propeller to the factory. Remove the spinner.
(b) Inspect the attaching bolts for worn or damaged threads and heads. Replace
damaged bolts with new ones.
(c) Inspect the spinner bulkheads for cracks or broken brackets. Replace if any
damage is noted.
