Propeller Installation for all fixed pitch propellers (except 1A162 model propellers).                   WARNING: MAKE SURE THE MAGNETO IS GROUNDED BEFORE INSTALLING  THE PROPELLER OR CONNECTING EXTERNAL POWER.                NOTE: McCauley recommends that propeller mounting nuts (if applicable) be replaced at each  propeller installation, whenever possible. However, nuts may be reused providing the threads are in good condition and the locking material prevents turning of the nut on the  stud by hand. Propeller mounting bolts must be magnetic particle inspected in accordance  with ASTM E-1444 or replaced whenever the propeller is removed from the engine.                NOTE: The aircraft maintenance manual or STC installation instructions should always be  consulted for any specialized procedures applicable to a specific aircraft....

        The following instructions are general in nature. The aircraft maintenance manual or STC  installation instructions should always be consulted for any specialized procedures applicable  to a specific aircraft. Various spinner arrangements not manufactured by McCauley may be  used which require additional procedures.         In the following instructions, installation of propeller is based on the assumption that a McCauley  spinner will be used. If a spinner is not used or if the spinner is not manufactured by McCauley, omit those steps which apply to the spinner.               WARNING: Verify that engine magnetos have been grounded prior to  approaching the propeller. Spinner Assembly Removal        (1) Make an alignment mark on the spinner shell, aft bulkhead and adjacent blade with a felt tip pen.  This index mark ensures accurate restoration of ...

Long Term Storage of Controllable Pitch Propellers                    A. The following is applicable to new and overhauled propellers prior to entering service (engine  installation) or at any time propeller is removed from service. Storage time is determined from date  of manufacture, overhaul, or removal from aircraft.                     (1) Storage must be in a clean and dry environment, preferably in the original shipping carton and  above ground level, to minimize exposure to dirt and moisture.                    (2) If storage period exceeds 2 years before entering service or returning to service perform the  following inspection: (a) For all propeller models, inspect externally for damage and corrosion. Inspection may be accomplished by an A & P mechanic or international equivalent. Make a logbook e...

REFERENCE : SAIB: CE-13-27  Date: April 5, 2013            The FAA recently received a report of a failed flap extend cable . The failure occurred on approach  when the flaps were deployed to 45 degrees. The sudden retraction of the right flap caused the  airplane to roll about 80 degrees to the right. The pilot was unable to retract the left flap, but was able  to maintain control with the assistance of a passenger, divert to another airport, and land safely by  utilizing almost full left aileron control. The report stated the cable was original (over 4,800 flight  hours), and the most recent 100-hour inspection had been completed approximately 10 flight hours  prior to cable failure.              A search of the FAA’s service difficulty report (SDR) system revealed numerous events of a similar  nature over a 20 year period. Most reports of fraying occurred near pulleys, and s...
