Page 32: Airframe Or Engine Modifications
Propeller Owner's Manual 3. Airframe or Engine Modifications A. Propellers are approved vibrationwise on airframe and engine combinations based on tests or analysis of similar installations. This data has demonstrated that propeller stress levels are affected by airframe configuration, airspeed, weight, power, engine configuration and approved flight maneuvers. Aircraft modifications that can effect propeller stress include, but are not limited to: aerodynamic changes ahead of or behind the propeller, realignment of the thrust axis, increasing or decreasing airspeed limits, increasing or decreasing weight limits (less significant on piston engines), the addition of approved flight maneuvers (utility and aerobatic). B. Engine modifications can also affect the propeller. The two primary categories of engine modifications are those that affect structure and those that affect power. An example of a structural engine modification is the alteration of the crankshaft or damper of a piston engine. Any change to the weight, stiffness or tuning of rotating components could result in a potentially dangerous resonant condition that is not detectable by the pilot. Most common engine modifications affect the power during some phase of operation. Some modifications increase the maximum power output, while others improve the power available during hot and high operation (flat rating) or at off-peak conditions. Examples of such engine modifications include, but are not limited to: changes to the compressor, power turbine or hot section of a turboprop engine; and on piston engines, the addition or alteration of a turbocharger or turbonormalizer, increased compression ratio, increased rpm, altered ignition timing, electronic ignition, full authority digital electronic controls (FADEC), or tuned induction or exhaust. C. All such modifications must be reviewed and approved by the propeller manufacturer before obtaining approval on the aircraft.
Page 33: Restrictions And Placards
(1) The restrictions, if present, will vary depending on the propeller, blade, engine, and/or aircraft model. (2) Review the propeller and aircraft type certificate data sheet (TCDS), Pilot Operating Handbook (POH), and any applicable Airworthiness Directives for specific information. 5. General A.

Page 54: Description Of Propeller And Systems
Propeller Owner's Manual 1. Description of Propeller and Systems A. General Operation and System Overview - Refer to Figure 2-2 (1) The propeller and control system provides constant speed (RPM) control in flight and manually controlled positive and reverse thrust for (slow speed) maneuvering. (2) Major components consist of (1) a propeller, (2) a governor, (3) a pressure control unit and (4) an oil pressure gage.
Page 55: Propeller And Pressure Control Unit Features
Propeller Owner's Manual (5) A second use for the propeller is on a lighter than air vehicle such as a blimp. Constant speed (RPM) control would be used during constant forward motion and manually controlled blade angle for maneuvering when close to the ground and during docking with a mooring mast.
Page 56 Propeller Owner's Manual Page 2-8 61-00-36 DESCRIPTION AND OPERATION Rev. 2 Feb/17...
Page 57 Propeller Owner's Manual (f) A cockpit mounted pressure gage is attached hydraulically to the pressure control unit. (g) During flight propeller blade angle is controlled by a governor to maintain a constant Propeller/Engine RPM. (h) During maneuvering (on land or water for fixed wing aircraft or close to the ground maneuvering of a craft that is lighter than air) reverse thrust as well as positive thrust is required and is available in beta range with manual blade angle control by the pilot.
Page 58: Propeller Governed Operation
Propeller Owner's Manual (d) For pressure control, the pressure control unit uses a pressure limiting configuration consisting of a relief valve and a pressure relief compression spring. The addition of a plunger to permit pilot input of a different position and load on the pressure relief compression spring, permits different/variable oil pressure output selection during beta range operation.
Page 59 Propeller Owner's Manual (3) During propeller operation the following forces are constantly present, (1) spring force, (2) counterweight force, (3) centrifugal twisting moment of each blade and (4) blade aerodynamic twisting forces. Spring and counterweight forces attempt to rotate the blades to higher blade angles while the centrifugal twisting moment of each blade is generally toward lower blade angles.
Page 60: Propeller Beta (Reverse) Operation
Propeller Owner's Manual D. Propeller Beta (Reverse) Operation - Refer to Figure 2-2 and Figure 2-3 (1) Propeller beta operation is in the range between low pitch and maximum reverse pitch. Blade pitch or blade angle is controlled manually by the pilot through a lever/cable connected to a plunger in the pressure control unit;...
Page 61 Propeller Owner's Manual Centrifugal locks built into the beta lockout assembly are RPM sensitive such that they will engage a groove in the hub barrel at RPMs above 900 RPM to prevent axial moment in the barrel of the hub. At an RPM below 900 RPM the centrifugal locks will retract into the body of the low pitch stop unit and permit axial movement in the barrel of the hub for beta range operation.
Page 62 Propeller Owner's Manual (6) Operation in beta range is at elevated pressures that are considerably above oil pressures required for constant speed operation as shown in Figure 2-3. The slope of the line representing oil pressures required for beta range operation is shown to be much steeper than for constant speed operation.
Page 63 Propeller Owner's Manual (7) The function of the Pressure Control Unit is to reduce the governor supplied oil pressure of 270 to 300 PSI to a lower oil pressure. Refer to Figure 2-2. One mode of reduction is fixed and the second is variable. The two modes of reduction are discussed in paragraphs 1.D.(7)(a) and 1.D.(7)(b).
Page 64 Propeller Owner's Manual (b) During maneuvering, the propeller operates in Beta Range (Low Pitch to Full Reverse Pitch) which is manually selectable. Manual selection of blade angle by the pilot is accomplished by moving the pilot control that pushes a Plunger into the Pressure Control Unit to increase the oil pressure allowed by the Pressure Control Unit to reach the propeller.
Page 65: Pilot Operation Of Propeller Blade Angle In Beta Range (Low Pitch To Full Reverse Pitch) For Maneuvering
Propeller Owner's Manual 2. Pilot Operation of Propeller Blade Angle in Beta Range (Low Pitch to Full Reverse Pitch) for Maneuvering A. The blade angle selection is manually controlled by the pilot.

Page 123 Propeller Owner's Manual (d) Figure 3-16 shows propeller control oil pressures that are required between the blade angle ranges of high pitch and maximum reverse pitch. The horizontal axis represents the blade angle of the propeller. The vertical axis represents the magnitude of oil pressure required for propeller control.
Page 124 Propeller Owner's Manual (g) The preloaded spring in the hub that is between the propeller blades and the engine flange, must be overcome by the propeller oil pressure before the blades will move from low pitch to lower blade angles in the beta range. Refer to Figure 2-2, “Pressure Control Reversing Propeller System”...
Page 125 Propeller Owner's Manual (k) Position 4 at low pitch blade angle must be determined. The objective is to determine what oil pressure is required to just reach low pitch blade angle during decreasing blade pitch. The blade model, counterweights, cylinder mounted springs, and friction resisting blade movement will affect the oil pressure required to reach low pitch blade angle.
Page 126 Propeller Owner's Manual (m) If the engine RPM reaches maximum before reaching maximum power, then the governor was activated to increase blade angle to stop the RPM increase and will have dropped the oil pressure shown on the cockpit mounted oil pressure gauge to a Position 1 location or lower.
Page 127 Propeller Owner's Manual (o) The pressure control unit plunger was repositioned into the pressure control unit by the pilot control and control lever. Refer to Figure 3-14 or Figure 3-15.

Propeller Owner's Manual 1. Introduction A. Propeller De-ice System (1) A propeller de-ice system is a system that removes ice after it forms on the propeller blades. A de-ice system uses electrical heating elements to melt the ice layer next to the blades, permitting the ice to be thrown from the blade by centrifugal force.
Page 220: System Description
Propeller Owner's Manual 2. System Description A. De-ice System NOTE: Because of the wide variances of various de-ice systems, the following description is general in nature. Consult the airframe manufacturer’s manual for a description of your specific de-ice system and controls.
Page 221: Anti-Ice System
Propeller Owner's Manual B. Anti-ice System (1) The anti-ice system is controlled by the pilot via a cockpit mounted rheostat.
