CIRRUSAIRPLANE MAINTENANCE MANUALMODEL SR22PROPELLER ASSEMBLY1. DESCRIPTIONThe propeller assembly consists of a hollow aluminum hub which supports the propeller blades and alsohouses the pitch changing mechanism. Movement of propeller blades is controlled by a hydraulic piston/cylinder combination mounted on the front of the hub.Serials 0002 & subs w/ Hartzell propeller: The linear motion of the hydraulic piston is transmitted to eachblade through a pitch change rod and fork. A pitch change knob at the base of each blade intersects withthe fork.Serials 0687 & subs w/ optional McCauley propeller: The linear motion of the hydraulic piston is transmitted to each blade through a piston rod, linkage assembly, and actuating pin. The actuating pin assembly issecured to the base of each blade with screws.Blade pitch is controlled by the governor. The governor supplies oil to the propeller hub to move the bladestoward high pitch position (decreased RPM). Conversely, the propeller blades move toward low pitch position (increase RPM) as the governor drains oil away from the propeller hub. A mechanical spring isinstalled within the propeller to assist movement of the blades to a lower pitch position as RPM decayssince blade centrifugal twisting moment is only present when the propeller is rotating. The mechanicalspring will ensure that blade angle will reach the low pitch stop when the propeller is static. If oil pressure islost at any time, the propeller will move to low pitch.The propeller assembly employs high-strength, aluminum or composite blades. It is essential that the propeller assembly be maintained in accordance with vendor recommended service procedures. Refer to themanufacturer’s approved Instructions For Continued Airworthiness and/or other service instructions.EFFECTIVITY:All61-10Page 115 Apr 2007

CIRRUSAIRPLANE MAINTENANCE MANUALMODEL SR22C. Adjustment/Test - Dynamic BalanceDynamic balancing reduces vibration produced by the propeller and powerplant. Small balanceweights are added to the propeller/crankshaft assembly to correct for errors in mass distribution sovibration is reduced. Refer to the manufacturer's Instructions for Continued Airworthiness for pertinentinformation regarding dynamic balancing.D. Inspection/Check - Blade TrackBlade track is the way one rotating blade tip follows the other in almost the same plane. Excessive difference in blade track may be an indication of bent blades or improper propeller installation. Refer tothe manufacturer's Instructions for Continued Airworthiness for pertinent information regarding bladetrack.E. Inspection/Check - Loose BladesAlthough blades should be tight in the propeller, slight movement is acceptable if blade returns to original position when released. Blades with excessive movement, or that do not return to original positionwhen released may indicate internal wear or damage. Refer to the manufacturer's Instructions for Continued Airworthiness for pertinent information regarding loose blades.F.Cleaning/PaintingPropeller blades are painted with a durable specialized coating that is resistant to abrasion. If this coating becomes eroded, it is necessary to re-paint the blades to provide proper corrosion and erosion protection. Refer to the manufacturer's Instructions for Continued Airworthiness for pertinent informationregarding painting.G. RepairsNicks, gouges, and scratches on blade surfaces or on leading or trailing edges must be removed priorto flight. Refer to the manufacturer's Instructions for Continued Airworthiness for pertinent informationregarding repairs.61-10Page 1015 Apr 2007EFFECTIVITY:All
