1Field Service Engineer McCauley Propeller Systems Building On The BestGary PeakField Service EngineerMcCauley Propeller SystemsGary J. told me I had one hour to present McCauley items, and if you were here at my last presentation you know, you do not want to listen to me for an hour. So I’ll try to make this as short and painless as possible.I’ve got 10 pieces of service information to mention the revision of, and some training, along with the current status of McCauley We are not sending production to MEXICO” we are staying in the US.
2Product Support for 2010 Technical Publications McCauley Training Foreign CertificationsThreaded PropellersService Bulletins & LettersPending service InformationField IssuesThese are the topics that I would like to cover todayAt the completion of these subjects, Chris Bell will be up to discuss new and upcoming service information in addition to some ongoing field issues that we have been receiving reports about
3Recent Manual Revisions MPC26 CD Owner’s Manual Rev. 1Original issue April, 2008Rev. 1 issued December, 2009 added the information for fixed pitch propellersContains owner’s manual information for all C200 through C1100 series as well as fixed pitch aluminum propellersThis CD is to be supplied with all constant speed and FP propellersLogbooks are still being supplied separately with each propeller
4Planned Manual Revisions MPC1100 (est. completion 4th qtr 2010)?CMM1100 (est. completion 4th qtr 2010)?BOM100 (est. completion 4th qtr 2010)?SPM100 (est. completion 4th qtr 2010)Should include C3400 hub informationWill include all De-Ice information( De-ice manual will be obsolete)The majority of revisions just incorporated published service information
6McCauley Training McCauley Training Advantages: Flexible training scheduleClass book provided can be used for future referenceCompetitive pricesKnowledgeable trainersCost effective way to train new employees without disrupting existing personnelAssistance in making lodging and rental car arrangementsMcCauley training facility is located in WichitaWe offer a full line of overhaul, assembly/disassembly, and informational trainingVisit the website to obtain specific course descriptions and scheduling information
7New Courses for 2010 C300/C500 Feathering Propeller Overhaul Intro. to McCauley Propeller and Field MaintenanceFixed Pitch Propeller MaintenanceBoot R& I Optional With Constant Speed OverhaulThe course listed here are new courses which were recently added
8McCauley Training Available Classes Constant Speed Overhaul Turbine OverhaulBlade Overhaul ManualC703 Field ReassemblyC1103 Field ReassemblyCourses Can Be CombinedVisit for a full list of available coursesMcCauley training facility is located in WichitaWe offer a full line of overhaul, assembly/disassembly, and informational trainingVisit the website to obtain specific course descriptions and scheduling information
9Owner’s/Operators Class Propeller/Governor operation theoryParticipate in a build up/tear down of a C400 series propellerDiscussion of active service letters and service bulletinsGeared towards aircraft owner’s and A&P’s that desire a better understanding of propellers and propeller operationEnables the pilot to better recognize potential areas of concern thus enhancing safetyDoes not qualify the students to perform any propeller maintenance
10Composite Training Development Composite Blade Overhaul1L100 OverhaulC3400 OverhaulWith the addition of composites to the McCauley product line, three new classes will be created for these new productsClasses are still under development
11Composite Blade Overhaul Class Damage assessment/InspectionMinor blade repairLeading edge guard replacementResonance testingDamage assessment of the composite blade is if the black carbon has been damaged, the blade is scrap3 layers of glass are over the carbon layer (approximately .030”)Blade repair will be similar to those used by other composite blade manufacturersMinor cracks in the LEG will be acceptableRemoval and replacement of a LEG will be accomplished in classAdditionally, the final determination of serviceability will be the resonance testX% of stiffness loss will be acceptable, anything over the limit will be scrap
12C3400 Composite Overhaul Class Design overviewOperational differencesDamage assessmentAssembly/DisassemblyAdjustmentsHub repairsWith the new internal pitch change mechanisms comes an entirely new assembly procedure and typical composite operational characteristics.Will require rebalance of the propeller blade to a master weightThis enables the replacement of a single blade in an assembly
131L100 Composite Overhaul Class Damage assessment/InspectionMinor Blade repairLeading edge guard replacementResonance testingDamage assessment and repair will be very similar to the constant speed blades with the addition of inspection/repair in the hub areaResonance testing will also be similar, but will utilize a different mounting method
14Composite Tooling Requirements Majority of tools utilized are common with other composite blade manufacturer’sMcCauley specific tooling:Resonance Test EquipmentResonance Testing Fixture/AdapterShank adapter for utilizing existing colletsMajority of tools/equipment are common to other composite bladesVacuum pump required for installation of new LEG and surface repairsCan hopefully utilize existing table at facility for testingA shank adapter will be required to utilize current 90 collets with the smaller constant speed shank
15Composite Qualification Complete qualification process still under developmentWill require procurement of applicable tools and fixturesApproved personnel must complete McCauley composite trainingMay require work to be completed on a “qualification blade” and then approved by McCauley prior to obtaining certificationLikely several years before a sizeable population of 1L100 and C3400 series propellers become numerous in the fieldThe propeller field maintenance plan is still under development, but please let me know if your shop would be interested in being considered for McCauley composite certification

18Threaded Propeller Part Production Ceased production of threaded blades in 2002Last parts orders for threaded parts was 10/1/2010Consumables and other purchase parts will continue to be available through McCauleyTechnical support of the product line will continue indefinitely99% of threaded propeller applications have another propeller alternative whether it be a McCauley or another manufacturerDifficult to manufacture and inspect due to close tolerances and complex, truncated threadsIntroduce Chris Bell

42Field Issues Deice lead restrainer strap installation Still having issues with tearing deice bootsPurpose of the restrainer strap is to hold down the lead not the bootLooking at the feasibility of leaving the restrainer strap location the same but positioning the boot farther outboard
43Field Issues Cad plated hardware You may notice a change in the appearance of the Cad plating on some of our hardware. We are changing from type I to type II.
44Enlist your Help We also want your help. Let us know if you have any ideas for new STC’s or other products to add to our line up.
