HARTZELL PROPELLER INC. SERVICE BULLETIN Propellers Propeller - Introduction of MV Shank Propellers HC-SB-61-232 Page 1 of 13 Mar 20/98 1. Planning Information A. Effectivity All aircraft using ( )H(C,A)-( )(2,3)(X,V)( )-( ) propellers with X or V shank "double shoulder" blades. Propellers are installed on, but not limited to, applications listed in Table 2. B. Concurrent Requirements None. C. Reason (1) Existing X and V shank propellers have been subject to the repetitive inspection requirements of Hartzell Service Bulletin HC-SB-61-217 and FAA Airworthiness Directive AD 97-18-02. A design improvement to the existing V shank propellers, called MV shank or modified V shank, has been implemented in new production propellers. Hartzell has began manufacturing an improved version of V shank propellers that are identified as "MV" propellers. The letters MV will be part of the model designation, for example HC-(A,D)(2,3)MV( )-( ). (2) The MV blade shank and blade clamp is a "single shoulder" design similar to that used successfully for many years in Hartzell turbine engine propellers. MV propellers are not subject to the requirements of Hartzell Service Bulletin HC-SB-61-217 and FAA Airworthiness Directive AD 97-18-02. (3) This Bulletin provides model designation information, data concerning replacement/superseded part numbers, and approval basis. D. Description This Bulletin provides general technical information concerning approval and applicability of new ( )HC-(A,D)(2,3)MV( )-( ) as replacement propellers for ( )HC-(1,8,D,A)(2,3)(X,V)( )-( ) models. E. Compliance Compliance is optional. F. Approval FAA approval has been obtained on technical data in this publication that affects type design. G. Manpower No additional manpower is required for propeller replacement. HARTZELL PROPELLER INC. SERVICE BULLETIN Propellers Propeller - Introduction of MV Shank Propellers Mar 20/98 HC-SB-61-232 Page 2 of 13 H. Weight and Balance When a MV shank propeller replaces a V shank propeller, weight is increased approximately two pounds for a two blade propeller and three pounds for a three blade propeller. I. Electrical Load Data Not changed. J.

Material Information A. Technical Differences between V shank propellers and MV shank propellers: NOTE: See applicable Propeller Manual 100E, Manual 114C, or Manual 118F revision 5 for detailed part number information. (1) The new MV shank design utilizes a single shoulder type of clamp to blade retention system, similar to that used for Hartzell turbine engine propellers, see Figure 1. (2) Blades - V shank blades are replaced by MV shank blades, for example V8433N is replaced by MV8433N. (However, field modification of an existing V shank to MV shank may be possible, see Service Bulletin HC-SB-61-233). (3) Blade Clamps - C-3-( ) series "double shoulder" clamps are replaced by D-6831-( ) "single shoulder" clamps, example: C-3-5A replaced by D-6831-5A. HARTZELL PROPELLER INC. SERVICE BULLETIN Propellers Propeller - Introduction of MV Shank Propellers HC-SB-61-232 Page 3 of 13 Mar 20/98 (4) Clamp gasket - A-47-1 is replaced by A-6871-1. (5) Clamp and Counterweight Assemblies - C-838-( ) are replaced by C-838-(1000 series numbers), example: C-838-60 replaced by C-838-1060. The new part numbers differ from the previous assemblies in that they use D-6831-( ) Clamps and A-6871-1 Clamp Gaskets, all other components are unchanged. B. Availability of propeller assemblies: (1) All future orders for V shank propellers will be changed to MV shank propellers. V shank propeller assemblies are no longer procurable from Hartzell. (2) Table 2 provides a listing of replacement propeller assemblies. A few models of very old, limited production designs are not procurable. If any such propellers are required, contact Hartzell Product Support Department for assistance. NOTE: Some components of early production designs were superseded with improved parts many years ago. Models with old split ring retainer type hubs with HC-1 or HC-8... model designation have been out of production for many years and replaced with HC-D or HC-A... type hubs. X shank blades have been superseded by V shank blades for many years. For example, an early production HC-82XL-2 propeller has been superseded by model HC-A2VL-2. Now, with the additional improvement of the MV type shank design, the current propeller design that will replace a HC-82XL-2 is a HC-A2MVL-2. C. Approval Basis: (1) The MV blade and propeller designs are approved under the same FAA Propeller Type Certificate as previous V shank propellers, see Table 1. (2) Many existing FAA Aircraft Type Certificate Data Sheets for the old aircraft affected by this Bulletin are unlikely to be revised to specifically reflect approval of the new MV type propellers. However, MV type propellers are approved for use on all applications that previously used X or V shank blades. There is a statement in the recently revised FAA Propeller Type Certificates for the ( )HC-(A,D)(2,3)MV( ) models that says the "MV" can be substituted for propeller models with "X" or "V" in the same location. NOTE: Similar conditions have existed for many years where V shank

blades were used to replace earlier X shank blades and A or D type HARTZELL PROPELLER INC. SERVICE BULLETIN Propellers Propeller - Introduction of MV Shank Propellers Mar 20/98 HC-SB-61-232 Page 4 of 13 hubs were used to replace earlier 1 or 8 type hubs. Applicable FAA Propeller Type Certificates have statements like: "...V may be substituted for X..." or "...A can be substituted for 8...". For many older propeller designs, the FAA Aircraft Type Certificate was never updated and may show, for example, a HC82XK-2 propeller even though a later HC-A2VK-2 propeller is usable and approved. Also, note that if a FAA Aircraft Type Certificate calls for a later propeller design (like A2VK), typically there is no provision to allow use of earlier designs (like 82XK). D. Spares support for parts used in HC-1 and 8 hubs, X and V shank propellers: (1) Spares support for V shank blades, C-3-( ) blade clamps, and related C-838-( ) clamp assemblies will continue to be procurable through September 30, 1999. After September 30, 1999, V shank blades and C-3-( ) blade clamps will no longer be procurable and: (a) Orders for C-3-( ) series clamps or clamp assemblies will be changed to D-6831-( ) type clamps (thereby requiring use of MV type blades); (b) Orders for C-838-( ) clamp/counterweight assemblies which use C-3-( ) type clamps will be changed to C-838-(1000 series) clamp/counterweight assemblies which use D-6831-( ) type clamps (thereby requiring use of MV type blades); (c) Orders for V shank blades will be changed to MV type blades. (2) Spares support for other component parts: (a) Parts for V shank propellers (other than clamps & blades) will remain procurable beyond September 30, 1999 as long as there is parts demand. This includes A-47-1 clamp gasket. (b) Parts for HC-1 and 8 series propellers (other than clamps, blades & hubs) will remain procurable beyond September 30, 1999 as long as there is reasonable parts demand. This includes: blade bearings and split ring retainers which are unique to these models. (c) Parts for X shank propellers - A-158L-( ) Pilot Tubes are no longer procurable (because propellers are to be converted from X shank to V shank). A-127-( ) Blade Bushings will remain procurable. E. Pricing - pricing information for propeller assemblies and major component parts is provided in an Appendix to this Bulletin. HARTZELL PROPELLER INC. SERVICE BULLETIN Propellers Propeller - Introduction of MV Shank Propellers HC-SB-61-232 Page 5 of 13 Mar 20/98 2. Accomplishment Instructions A. Installation and Maintenance of "MV" propellers: (1) If a MV shank propeller is used to replace an older X or V shank propeller, no additional or different installation or maintenance instructions are required, however, overhaul intervals may be different, refer to latest revision of Hartzell Service Letter 61 for details. Aside from the propeller itself, no additional or different parts are required. (2) Make logbook entry that shows the new propeller/blade model and serial number information. Include a statement that the propeller was installed in accordance with this Bulletin. It may be desirable to include a statement that compliance with FAA AD 97-18-02 is no longer required. B. Overhaul, Assembly, and Disassembly Procedures and Part Number information for "MV" propellers: (1) Assembly, disassembly, overhaul and part number information for "MV" type propellers is found in either: Hartzell Propeller Maintenance Manual 100E, Manual 114C, or Manual 118F revision 5 depending on the specific propeller model. (2) Hartzell Standard Practices Manual 202A, revision 8 or subsequent, contains information concerning steel hub overhaul and blade clamp information. (3) Hartzell Aluminum Blade Manual 133C, revision 3 or subsequent, contains information concerning "MV" series blades. Blade airfoil repair data (minimum widths, thicknesses, etc.) for MV blades remains identical to that for existing V shank blades. Blade shank inspection and tooling for compressive rolling of blade shank is provided. NOTE: X and V shank propeller blades have a shot peened surface in the retention area. MV blade shanks are compressive rolled instead of shot peened. HARTZELL PROPELLER INC.
