ACTION: Notice of proposed rulemaking

SUMMARY: The Federal Aviation Administration (FAA) proposes to revise an existing airworthiness directive (AD), applicable to Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series and HA-A2V20-1B series propellers with aluminum blades. That AD currently requires initial and repetitive dye penetrant and eddy current inspections of the blade and an optical comparator inspection of the blade retention area, and, if necessary, replacement with serviceable parts. In addition, that AD currently requires initial and repetitive visual and magnetic particle inspection of the blade clamp, dye penetrant inspection of the blade internal bearing bore, and, if necessary, replacement with serviceable parts. Also, for all HC-(1,4,5,8)(2,3)(X,V)( )-( ) steel hub propellers, that AD currently requires an additional initial and repetitive visual and magnetic particle inspection of the hub, and, if necessary, replacement with serviceable parts. This proposal would revise that AD by introducing as an optional terminating action for the initial and repetitive inspections of that AD, replacement of affected propellers with Hartzell Propeller Inc. model "MV" series propellers. This proposal is prompted by type certification approval of the Hartzell "MV" series propellers that are direct replacements for the affected propellers, and service bulletin approval to allow modification of affected propellers to the "MV" type design configuration. The Hartzell "MV" series propellers were certified as Hartzell propeller models ( )HC-( )(2,3)MV( )-( ) and HA-A2MV20-1B. The actions specified by the proposed AD are intended to prevent blade separation due to cracked blades, hubs, or blade clamps, which can result in loss of control of the airplane.
DATES: Comments must be received by March 3, 2003.
ADDRESSES: Submit comments in triplicate to the Federal Aviation Administration (FAA), New England Region, Office of the Regional Counsel, Attention: Rules Docket No. 96-ANE-40-AD, 12 New England Executive Park, Burlington, MA 01803-5299. Comments may be inspected at this location, by appointment, between 8 a.m. and 4:30 p.m., Monday through Friday, except Federal holidays.

Discussion

On August 15, 1997, the Federal Aviation Administration (FAA) issued airworthiness directive (AD) 97-18-02, Amendment 39-10112 (62 FR 45309, August 27, 1997), applicable to Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series propellers and HA-A2V20-1B series propellers, to require initial and repetitive dye penetrant and eddy current inspections of the blade and an optical comparator inspection of the blade retention area, and, if necessary, replacement with serviceable parts. In addition, that AD was issued to require initial and repetitive visual and magnetic particle inspections of the blade clamp, dye penetrant inspections of the blade internal bearing bore, and, if necessary, replacement with serviceable parts. Also, that AD was issued to require for all HC-(1,4,5,8)(2,3)(X,V)( )-( ) steel hub propellers, an additional initial, and repetitive visual and magnetic particle inspections of the hub and, if necessary, replacement with serviceable parts. That action was prompted by reports of cracked blades, blade clamps, and hubs and reports of blade separations. That condition, if not corrected, could result in loss of control of the airplane.

Hartzell Certification Efforts To Create Optional Terminating Action To Address AD 97-18-02

Since issuance of that AD, Hartzell Propeller Inc. has received type certification approval of the Hartzell "MV" series of propellers that are direct replacements for the affected propellers. The Hartzell "MV" series propellers were certified as Hartzell propeller models ( )HC-( )(2,3)MV( )-( ) and HA-A2MV20-1B. Also, Hartzell Propeller Inc. service bulletins (SB's) HC-SB-61-232, dated March 20, 1998, and HC-SB-61-233, dated April 17, 1998, have been approved to allow modification of affected propellers to the "MV" type design configuration. This proposal would introduce as an optional terminating action, for the initial and repetitive inspections of this proposal, replacement of affected propellers with Hartzell Propeller Inc. model "MV" series propellers.

Manufacturer's Service Information

The FAA has reviewed and approved the technical contents of Hartzell Propeller Inc. SB No. HC-SB-61-217, Revision 1, dated July 11, 1997, that describes procedures for fluorescent dye penetrant and eddy current inspections of the blade and an optical comparator inspection of the blade retention area, and, if necessary, replacement with serviceable parts. In addition, this SB describes procedures for visual and magnetic particle inspection of the blade clamp, dye penetrant inspection of the blade internal bearing bore and, if necessary, replacement with serviceable parts. For all HC-(1,4,5,8)(2,3)(X,V)( )( ) steel hub propellers, this SB describes an additional visual and magnetic particle inspection of the hub, and, if necessary, replacement with serviceable parts.

FAA's Determination of an Unsafe Condition and Proposed Actions

Since an unsafe condition has been identified that is likely to exist or develop on other Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series and HA-A2V20-1B series propellers of this same type design, the proposed AD would revise AD 97-18-02 to continue to require:
  • Initial and repetitive dye penetrant and eddy current inspections of the blade and an optical comparator inspection of the blade retention area, and, if necessary, replacement with serviceable parts.
  • Initial and repetitive visual and magnetic particle inspection of the blade clamp, and, if necessary, replacement with serviceable parts.
  • Initial and repetitive dye penetrant inspection of the blade internal bearing bore, and, if necessary, replacement with serviceable parts.
  • For all HC-(1,4,5,8)(2,3)(X,V)( )-( ) steel hub propellers, an additional initial and repetitive visual and magnetic particle inspection of the hub, and, if necessary, replacement with serviceable parts.
  • A reporting requirement to obtain additional data and determine if adjustment can be made to the repetitive inspection intervals, with possible relief.

    This proposal also adds as an optional terminating action for the initial and repetitive inspections of this proposal, replacement of affected propellers with Hartzell Propeller Inc. model MV propellers.

    Economic Analysis

    Since the proposed revision to AD 97-18-02 is to add an optional terminating action, the total cost of the proposed revised AD on U.S. operators can be estimated to be $0.

    Regulatory Analysis

    This proposed rule does not have federalism implications, as defined in Executive Order 13132, because it would not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. Accordingly, the FAA has not consulted with state authorities prior to publication of this proposed rule.

    For the reasons discussed above, I certify that this proposed regulation (1) is not a "significant regulatory action" under Executive Order 12866; (2) is not a "significant rule" under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and (3) if promulgated, will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. A copy of the draft regulatory evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.

    Note 1: The above is not a complete list of aircraft which may contain the affected Hartzell Propeller Inc. ( )HC-( )(2,3)(X,V)( )-( ) series and HA-A2V20-1B series propellers with aluminum blades because of installation approvals made by, for example, Supplemental Type Certificate or field approval under FAA Form 337 "Major Repair and Alteration." It is the responsibility of the owner, operator, and person returning the aircraft to service to determine if an aircraft has an affected propeller.

    Note 2: The parentheses that appear in the propeller models indicate the presence or absence of additional letter(s) which vary the basic propeller hub model designation. This airworthiness directive is applicable regardless of whether these letters are present or absent on the propeller hub model designation.

    Note 3: This AD applies to each propeller identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For propellers that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (h) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.

    Compliance: Compliance with this AD is required as indicated, unless already done.
