reinstalled on the engine.

(2) Use only the approved consumables, e.g., cleaning agents, lubricants, etc.
(3) Safe Handling of Paints and Chemicals

(a) Always use caution when handling or being exposed to paints and/or

chemicals during propeller overhaul and maintenance procedures.

(b) Before using paint or chemicals, always read the manufacturer’s label on

the container and follow specified instructions and procedures for storage,

preparation, mixing, and application.

information about physical properties, health, and physical hazards of any

chemical.

(4) Observe applicable torque values during maintenance.
(5) 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 the overhaul facility

before return to service.
(a) Dynamic balance is recommended, but may be accomplished at the

discretion of the operator, unless specifically required by the Hovercraft or

engine manufacturer.

3. Component Life and Service

A. Overhaul (Major Periodic Inspection)

(1) Overhaul (Major Periodic Inspection) is the periodic disassembly, cleaning,

inspection, repairing as necessary, reassembly, and testing of a component.

NOTE: Throughout the text of this publication the terms Major Periodic

Inspection and Overhaul are considered interchangeable.

(2) The overhaul interval is based on hours of service (operating time) or on

calendar time.

(a) At such specified periods, the propeller hub assembly and the blade

assemblies should be completely disassembled and inspected for cracks,

wear, corrosion, and other unusual or abnormal conditions. As specified,

certain parts should be refinished, and certain other parts should be

replaced.

(3) Contact the Hartzell Propeller Inc. Product Support Department for specific

information concerning overhaul (major periodic inspection).

B. Rework

(1) Rework is correction of major damage caused by physical mishap or failure.
(2) Rework is done on an irregular basis as necessary and required. The propeller

may have to be re-balanced after rework procedures.

(3) Certain rework procedures, such as shot peening, must be performed at the

Hartzell Propeller Inc. factory or in a facility that has been approved by Hartzell

Propeller Inc.

(4) The amount, degree, and extent of major damage determine whether or not a

component can be reworked without overhaul.

C. Repair

(1) Repair is correction of minor damage caused during normal operation. It is

done on an irregular basis, as required.

(2) The amount, degree, and extent of damage determine whether or not a

component can be repaired without overhaul.

Page 1-7

Rev. 4 Nov/18

INTRODUCTION

OPERATION, MAINTENANCE MANUAL, AND LOGBOOK

D. Component Life

(1) Component Life is expressed in terms of total hours of service (Time Since

New, TSN) and in terms of hours of service since overhaul (Time Since

Overhaul, TSO).

(2) Both references are necessary in defining the life of the component.

Occasionally a part may be “life limited,” which means that it must be replaced

after a specified period of use.

(3) Overhaul returns the component or assembly to zero hours TSO (Time Since

Overhaul), but not to zero hours TT (Total Time).

(4) Rework or repair without overhaul does not affect TSO or TT.

E. Propeller Critical Parts

(1) Procedures in this manual may involve Propeller Critical Parts. These

procedures have been substantiated based on Engineering analysis that

expects this product will be operated and maintained using the procedures and

inspections provided in the ICS for this product. Refer to the Illustrated Parts

List chapter for the applicable propeller model for the identification of Propeller

Critical Parts.

(2) Numerous propeller system parts can produce an aircraft Major or Hazardous

effect, even though those parts may not be considered as Propeller Critical

Parts. The operating and maintenance procedures and inspections provided

in the ICS for this product are, therefore, expected to be accomplished for all

propeller system parts.

Functional Description and Operation of Propeller System

A. The Hartzell Propeller Inc. Hovercraft propellers consists of the a variable pitch

propeller assembly, a beta tube assembly, and a beta manifold. The propeller

assembly is a dual acting system.

The propeller assembly may be a single acting

or a dual acting system. Refer to Table 2-1 and Table 2-2 for propeller model

definitions.

The beta tube assembly is connected to a high pressure oil source and fitted to the

propeller through the beta manifold assembly. When commanded to change blade

pitch, the beta tube assembly is moved to the corresponding position and directs

high pressure oil to the propeller assembly.

. The beta manifold assembly is connected to the hydraulic oil drain port and drains

the oil from the propeller when the propeller is changing blade pitch.

. The propeller assembly is constructed of a two piece aluminum hub and composite

blades.

A cover plate and cylinder create a cylinder cavity to house the piston.

The piston is connected to the fork through a pitch change rod.

The direction of oil pressure to one side of the piston corresponds to a movement in

the fork, which in turn, changes the blade angle of the composite propeller blades.

. The propeller assembly incorporates a pin to permit the blades to be manually set at

a pre-determined angle. This permits the propeller to provide thrust in the event of a

propeller oil system failure.

Description of Composite Blade

. The Hartzell

Propeller Inc.

composite blade is composed of a metal blade shank

retention section. A low-density foam core is molded into the metal blade shank and

supports built-up layers of composite laminate (

Figure 2-2)

. An erosion shield of electroformed nickel is bonded to the blade to protect the blade

leading edge from erosion and impact damage.

. Filament windings of composite material provide blade retention of the blade

material to the internal metal blade plug (

Figure 2-3)

. The composite laminates

that

are a structural component of the blade,

also provide a retention load path directly

under the bearing for blade retention.

. Some designs use a filament winding on the inboard end of the erosion shield to

aid the retention of the erosion shield. This winding is sometimes referred to as an

erosion shield winding and should not be confused with the blade retention winding

used to secure the blade material to the internal metal plug.

. The composite blade is balanced in the horizontal plane during production by adding

lead wool to a centrally located balance tube in the metal blade shank

that

may

protrude into the blade’s foam

core.

. The blades are painted with a finish covering of paint to protect the entire blade from
