Page 4 Propeller Owner’s Manual WARNING (Rev. 1) People who fly should recognize that various types of risks are involved; and they should take all precautions to minimize them, since they cannot be eliminated entirely. The propeller is a vital component of the aircraft. A mechanical failure of the propeller could cause a forced landing or create vibrations sufficiently severe to damage the aircraft, possibly causing it to become uncontrollable.
Page 5 Failure could be as severe as loss of a propeller or propeller blades and cause loss of propeller control and/or loss of aircraft control. Hartzell Propeller Inc. follows FAA regulations for propeller certification on certificated aircraft. Experimental aircraft may operate with unapproved engines or propellers or...

(3) This manual may include multiple design types. (a) Parentheses shown in the propeller model designations in this or other Hartzell Propeller Inc. publications indicate letter(s) and/or number(s) that may or may not be present because of different configurations permitted on the various aircraft installations.
Page 34 (6) Before installing the propeller on the engine, the propeller must be statically balanced. New propellers are statically balanced at Hartzell Propeller Inc. Overhauled propellers must be statically balanced by a certified propeller repair station with the appropriate rating before return to service.
Page 35: Airframe Or Engine Modifications
(11) If the propeller is equipped with an ice protection system that uses components supplied by Hartzell Propeller Inc., applicable instructions and technical information for the components can be found in Hartzell Propeller Inc. Ice Protection System Manual 180 (30-61-80). (12) Propeller ice protection system components not supplied by Hartzell Propeller Inc.
Page 36: Engine Modifications
Propeller Owner’s Manual B. Engine Modifications (1) Engine modifications can affect the propeller. The two primary categories of engine modifications are those that affect structure and those which 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.

Page 50 Propeller Owner’s Manual Term Definition Corrosion (Steel) Typically, an electrochemical process that requires the simultaneous presence of iron (component of steel), moisture and oxygen. The iron is the reducing agent (gives up electrons) while the oxygen is the oxidizing agent (gains electrons).

Propeller Owner’s Manual 1. Description of Propellers and Systems A. Feathering Propellers HC-B(3,5)( )( )-2( ) Refer to Figure 2-1. The propellers described in this section are constant speed, feathering, and non-reversing. They use a single oil supply from a governing device to hydraulically actuate a change in blade angle.
Page 68 Propeller Owner’s Manual While the propeller is operating, 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. The spring and counterweight forces attempt to rotate the blades to higher blade angle, while the centrifugal twisting moment of each blade is generally toward lower blade angle.

Propeller Owner’s Manual B. Feathering and Reversing Propellers HC-B(3,4,5)( )( )-3( ) Series (External Beta System) Refer to Figure 2-3. The propellers described in this section are constant speed, feathering and reversing. They use a single oil supply from a governing device to hydraulically actuate a change in blade angle.
Page 72 Propeller Owner’s Manual The summation of the propeller forces is toward higher pitch (low RPM) and is opposed by a variable force toward lower pitch (high RPM). The variable force is oil under pressure from a governor with an internal pump, which is mounted on and driven by the engine.
Page 73 Propeller Owner’s Manual In reverse mode of operation, the governor operates in an underspeed condition to act strictly as a source of pressurized oil, without attempting to control RPM. Control of the propeller blade angle in reverse is accomplished through the beta valve.
Page 74: Start Lock Unit On Hc-B(3,4,5)( )( )-3( )
Propeller Owner’s Manual Shortly after engine start-up, with the propeller RPM above 800, the latch pins in the start lock units will still retain the blade angle. To release the latch pins, it is necessary to manually actuate the propeller slightly toward reverse. This will move the clamp-mounted plate, allowing the latch pins to slide freely.

Propeller Owner’s Manual C. Feathering and Reversing Propellers HC-B(3,4,5)( )( )-5( ) Series (Internal Beta System) Refer to Figures 2-5 through 2-7. The propellers described in this section are constant speed, feathering and reversing. They use a single oil supply from a governing device to hydraulically actuate a change in blade angle.
Page 80 Propeller Owner’s Manual The summation of the propeller forces is toward higher pitch (low RPM) and is opposed by a variable force toward lower pitch (high RPM). The variable force is oil under pressure from a governor with an internal pump, which is mounted on and driven by the engine.

Page 82 Centrifugal force will compress the springs and disengage the pins from the plate. Hartzell Propeller Inc. -5 series propellers incorporated various start lock unit configurations. (1) Certain three-bladed and four-bladed propellers incorporate a one-piece spinner mounting plate that is pinched between the hub and engine flanges.

Page 95: Governors
Propeller Owner’s Manual 3. Governors (Rev. 1) A. Theory of Operation (1) A governor is an engine RPM sensing device and high pressure oil pump. In a constant speed propeller system, the governor responds to a change in engine RPM by directing oil under pressure to the propeller hydraulic cylinder or by releasing oil from the hydraulic cylinder.
Page 96: Feathering Governor
Propeller Owner’s Manual (5) Feathering governors allow oil to be pushed from the propeller to the engine drain to increase propeller pitch to feather. (a) Some governors will move the propeller to feather by electrically or mechanically actuating a valve that opens to drain the oil supply between the propeller and governor to increase propeller pitch and allow the propeller to feather.
Page 97: Synchronizer/Synchrophaser Governor
Figure 2-14 illustrates a governor as a component of a synchronizing or synchrophasing system. (a) Hartzell Propeller Inc. synchronizing or synchrophasing systems use one engine (the master engine) as an RPM and phase reference and adjust the RPM of the remaining engine(s) [slave engine(s)] to match it.
Page 98: Governor Model Designation
Propeller Owner’s Manual B. Governor Model Designation (1) Hartzell Propeller Inc. uses a model number designation system to identify specific governor models. (2) The governor model number is stamped on the base and/or body of the governor assembly. (3) Refer to Table 2-3 for a description of the characters used in the governor model number.

Page 181: Engine Speed Varies With Airspeed
Propeller Owner’s Manual (b) Hunting and/or surging may also be caused by friction or binding within the governor control, or internal propeller corrosion, which causes the propeller to react slower to governor commands. To isolate these faults, the propeller must be tested on a test bench at a certified propeller repair station with the appropriate rating.

Page 227: Spinner Cleaning And Polishing
Propeller Owner’s Manual B. Spinner Cleaning and Polishing (1) Clean the spinner using the General Cleaning procedures in this section. (2) If an aluminum spinner dome is installed, polish the dome (if required) with an automotive-type aluminum polish. 2. Lubrication (Rev.
Page 228: Lubrication Procedure
Propeller Owner’s Manual (2) Owners of high use aircraft may wish to extend their lubrication intervals. The lubrication interval may be gradually extended after evaluating bearing wear and internal corrosion when the propeller is overhauled. (3) New or newly overhauled propellers should be lubricated after the first one or two hours of operation because centrifugal loads will pack and redistribute grease which can result in a propeller imbalance.
Page 229 Propeller Owner’s Manual CAUTION: USE ONLY HARTZELL PROPELLER INC. PROPELLER APPROVED GREASE. DO NOT MIX DIFFERENT SPECIFICATIONS AND/OR BRANDS OF GREASE EXCEPT AS NOTED IN THIS SECTION. (4) A label is normally applied to the propeller to indicate the type of grease previously used. Refer to Figure 6-2.
Page 230 (a) EXCEPTION: Aeroshell 5 and Aeroshell 6 greases both have a mineral oil base and the same thickening agent; therefore, mixing of these two greases is permitted in Hartzell propellers. WARNING: WHEN MIXING AEROSHELL 5 AND AEROSHELL 6 GREASES, THE...
