        The latest revision of the McCauley MPC-26 Owners/Operators Manual now encompasses all instructions for continued airworthiness (ICA).           This includes ICA information formerly published in overhaul manuals, component maintenance manuals, SB137 (TBO), SL1995-4 (blade repair) and other various documents.                  The MPC-26 also contains Airworthiness Limitations, Time Between Overhaul (TBO), and instructions for Removal/Installation, Troubleshooting, Preventive Maintenance and Repair.         The new revision provides “one-stop” shopping for all McCauley ICA information on current production constant speed reciprocating and turbine propellers, fixed pitch propellers, governors and accumulators.

        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...

                  Note the factory is quoted verbatim here per Lycoming SL 180B: "Pulling engines through by hand when the aircraft is not run or flown for a week or so is not recommended. Pulling the engine through by hand prior to start or to minimize rust and corrosion does more harm than good. The cylinder walls, piston, rings, cam and cam followers only receive splash and vapor lubrication. When the prop is pulled through by hand, the rings wipe oil from cylinder walls."                   "The cam load created by the valve train wipes oil off the cam and followers. After two or three times of pulling the engine through by hand without engine starts, the cylinders, cam and followers are left without a proper oil film. Starting engines without proper lubrication can cause scuffing and scoring of parts resulting in excessive wear."                ...

         McCauley - To Overhaul or reseal... That is the Question         In these times of belt tightening and dwindling budgets, the question arises: Overhaul or just reseal that Prop? The short answer is to overhaul that Propeller. To understand why, an understanding of the tasks and how they differ is necessary.      An overhaul is a reconditioning of the propeller to keep it in airworthy condition.      First, the propeller is completely disassembled and cleaned. All seals, gaskets, and hardware are replaced. The wear areas on the remaining internal parts are measured to make sure they are still within service limits. Plated parts are replated for corrosion protection and in some cases the plating will bring them back up to new production specifications. Also, all remaining parts will have Non-Destructive Inspections performed to check for hidden damage or cracks. The blades will have all the nicks and...

            Lycoming issued Mandatory Service Bulletin No. 533B dated October 4, 2012 that Supersedes Service Bulletin No. 533A) SUBJECT: Recommended Action for Sudden Engine Stoppage, Propeller/Rotor Strike or                      Loss of Propeller/Rotor Blade or Tip MODELS AFFECTED: All Lycoming direct drive reciprocating aircraft engines                          TIME OF COMPLIANCE: BEFORE FURTHER FLIGHT   This Service Bulletin identifies propeller/rotor damage conditions and gives corrective action recommendations for aircraft engines that have had propeller /rotor damage as well as any of the following:                 · Separation of the propeller/rotor blade from the hub                  · Loss of a propeller or rotor blade...

DESCRIPTION. An all-metal. fixed-pitch propeller, equipped with a spinner. REMOVAL a. Remove spinner  b. Remove safety wire from mounting bolt heads . c. Remove bolts and washers and remove forward bulkhead. NOTE The aft spinner bulkhead  is installed between propeller  and crankshaft flange and is removed as the  propeller is removed. INSTALLATION. a. Clean mating surfaces of propeller. crankshaft flange and spinner bulkheads. NOTE Ensure that nose cap is installed prior to completing  following steps. b. Position aft spinner bulkhead between propeller and crankshaft flange. c. Align propeller blade with t.c. mark on aft side of ring gear, and rotate propeller clockwise, as viewed from the front, to first bolt hole. d. Install forward spinner bulkhead and propeller bolts. e. Tighten bolts evenly, then torque to 300-320 lb.-in. or 25-26 lb-ft. f. Safety wire propeller mount bolts, ensuring that safety wire is around bolt heads not over top. ...

Propellers always be treated as ‘live’.               A report in the AAIB Bulletin  concerns a Beagle Pup whose engine burst into life while the  pilot was turning the propeller as part of the external pre-flight checks as described in his copy of the  aircraft’s Flight Manual. Because the throttle was fully open and the mixture fully rich, again in  accordance with the written procedure, the aircraft broke free of its tie-downs, clipped the wing of a  parked aeroplane, and crashed into an earth embankment.            It appears that the ignition switch was actually selected to ‘left’ despite there being no key in the  switch. However, the investigation was particularly concerned with the Flight Manual procedure, and  amendments have been made to all Pup Flight Manuals to require an idle throttle setting and mixture to  CUTOFF during the pre-flight check.     ...
