Airworthiness Directives; Hartzell Propeller, Inc. Compact Series Propellers

AGENCY : Federal Aviation Administration, DOT.

ACTION : Notice of proposed rulemaking (NPRM).

SUMMARY : The Federal Aviation Administration (FAA) proposes to supersede an existing airworthiness directive (AD) that is applicable to Hartzell models ( )HC

– ( )( )Y( )

– ( )( )( ) compact series, constant speed or feathering propellers with Hartzell manufactured ‘‘ Y ’’ shank blades. That AD currently requires initial and repetitive blade inspections; rework of all ‘‘ Y ’’ shank blades including cold rolling of the blade shank retention radius; blade replacement and modification of pitch change mechanisms for certain propeller models; and changing the airplane operating limitations with specific models of propellers installed. These inspections and modifications are required to detect and prevent fatigue cracks that might result in blade separation. This proposal would require initial blade inspections, with no repetitive inspections; rework of all ‘‘ Y ’’ shank blades including cold rolling of the blade shank retention radius, blade replacement and modification of pitch change mechanisms for certain propeller models; and changing the airplane operating limitations with specific models of propellers installed. This proposal is prompted by FAA reviews of propeller service histories since the issuance of AD 77

– 12

– 06 R2. The actions specified by the proposed AD are intended to prevent failure of the propeller blade from fatigue cracks in the blade shank radius, which can result in damage to the airplane and loss of airplane control.

Discussion

On December 15, 1977, AD 77

– 12

– 06 R2, Amendment 39

– 3097 (42 FR 63165, 1977), was published to mandate initial and repetitive inspections and rework of all Hartzell models ( )HC

– ( )( )Y( )

– ( )( )( ) compact series, constant speed or feathering propellers with Hartzell manufactured ‘‘ Y ’’ shank blades, including cold rolling of the blade shank retention radius, and, change of the airplane operating limitations with specific models of propellers installed, to detect and prevent fatigue cracks that might result in blade separation. In addition, that AD mandates inspection requirements for propellers that have experienced overspeed or ground or object strike. This proposed action would remove the repetitive inspection intervals to require the cold rolling of the blade shank retention radius to be a one-time final action, and remove the reference to propellers that have experienced overspeed or ground or object strikes.

During inspections performed to comply with AD 77

– 12

– 06 R2, some corroded parts were found, and several reports of corrosion were submitted to the FAA. The FAA has carefully considered these reports and has determined that this action need not include any action regarding corrosion. This action, and the current AD, are intended to prevent failure of the blade shank retention radius due to cracks.

Some operators have perceived AD 77

– 12

– 06 R2 as mandating an overhaul. While the FAA encourages owners and operators to have their propellers overhauled using the manufacturer ’ s recommended overhaul schedules, AD 77

– 12

– 06 R2 does not mandate a propeller overhaul. This proposal also does not propose to mandate a propeller overhaul. Review of Propeller Service Histories

The current AD, AD 77

– 12

– 06 R2, requires an initial inspection and cold rolling of the blade shank retention radius, then repetitive inspections and, if necessary, rework of the blade shank at intervals specified in Hartzell Service Letter (SL) 61B. In 1992, the FAA approved as an alternative method of compliance to the current AD, Hartzell SL 61R, dated February 28, 1992, which expanded the inspection interval to every 12,000 hours. Since the issuance of Hartzell SL 61R, there have been no reports of cracked blades in the blade shank retention radius (when the propeller complied with AD 77

– 12

– 06 R2). Therefore, the FAA has determined that the cold rolling of the blade shank retention radius can act as a final action to address the fatigue crack problem of the blade shank. Accordingly, this proposal removes the repetitive inspection requirement found in the current AD.

In addition, this proposal will eliminate the existing AD ’ s mandatory inspection requirements for propellers that have experienced an overspeed or ground or object strike. The FAA reviewed propeller service histories and found no overspeed or ground strike events to have caused a fatigue failure in the blade shank retention radius when the propeller is inspected in accordance with Hartzell ’ s service instructions for overspeed or ground strike events. These service instructions are published in the Hartzell Standard Practices Manual 202A, and in the current revisions of the propeller

owner ’ s manuals.

However, the mandatory airplane operating limitations changes will remain unchanged from the existing AD and these limitations consist of restricted propeller revolutions per minute (rpm), placarding the airplane instrument panel, and revising the engine tachometer markings in accordance with Hartzell Service Bulletin (SB) No. 118A, dated February 15, 1977. This proposal will maintain the existing AD ’ s modification of certain propeller models in accordance with Hartzell Propeller, Inc. Service Letter (SL) No. 69, dated November 30, 1971, and Hartzell Propeller, Inc. SB No. 101D, dated December 19, 1974. This proposal would not require operators to reinspect propellers that have already been inspected to comply with the current AD.

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 propellers of the same type design used on airplanes registered in the United States, the proposed AD would require, if not already accomplished, initial inspections and rework of all ‘‘ Y ’’ shank blades, including cold rolling of the retention radius, blade replacement and modification of pitch change mechanisms for certain propeller models, and change of the airplane operating limitations, to detect and prevent fatigue cracks that can result in blade separation and possible loss of airplane control. The actions would be required to be accomplished in accordance with Hartzell SB 118A, dated February 15, 1977, Hartzell SL 69, dated November 30, 1971, and Hartzell SB 101D, dated December 19, 1974. Requirement Removed for Hartzell Service Letter 61B

Hartzell Service Letter 61B, dated September 10, 1976 was initially incorporated by reference in AD 77

– 12

– 06 R2 to specify the inspection interval. Revisions to this service letter have been approved up to Revision V. Since the proposed AD removes the repetitive inspection, there will be no further need to reference any revision of SL 61. Economic Analysis

At the time the existing AD was issued, there were about 55,000 propellers of the affected design in the worldwide fleet. The FAA estimated that there were 35,750 propellers installed on airplanes of U.S. registry. The FAA expects that all of the affected propellers should have already been inspected to comply with the existing AD ’ s requirements to inspect, and rework or replace the blades. If these actions have not already been accomplished, then the total cost to comply with this proposal is estimated to be $700 per propeller.


### 58079 Federal Register / Vol. 66, No. 224 / Tuesday, November 20, 2001 / Proposed Rules

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

Note 1: 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 (e) 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. Propeller maintenance records showing compliance with AD 77

– 12

– 06 R2 is an indication that compliance was previously done.

To prevent failure of the propeller blade from fatigue cracks in the blade shank radius, which can result in damage to the airplane and loss of airplane control, do the following:

(a) Propellers are considered in compliance with the one-time inspection and rework requirements only, of this AD if:

(1) All blades are serial number D47534 and above, or

(2) All blades are identified with the letters

‘‘ PR ’’ or ‘‘ R ’’ or ‘‘ SP

–P ’’ ink-stamped on the camber side, or the letters ‘‘ SP ’’
, ‘‘ RD ’’ or

‘‘ SP

–P ’’ metal-stamped on the blade butt. Models ( )HC

– ( )( )Y( ) Compact Series ‘‘ Y ’’ Shank Propellers

(b) If propellers models ( )HC

– ( )( )Y( ) have not been inspected and reworked in accordance with AD 77

– 12

– 06 R2, then before further flight, do a one-time action to remove, inspect, rework or replace blades if necessary in accordance with Hartzell Service Bulletin (SB) 118A, dated February 15, 1977.

Note 2: One requirement in SB 118A is the cold rolling of the propeller blade shank. This is a critical requirement in the prevention of cracks in the blade. Propeller repair shops must obtain and maintain proper certification to perform the cold rolling procedure. For a current list of propeller overhaul facilities approved to perform the blade shank cold rolling procedure, contact Hartzell Product Support, telephone: (937) 778

–4379. Not all propeller repair facilities have the equipment to properly perform a cold roll of the blade shanks. In addition, any rework in the blade shank area will also necessitate the cold rolling of the blade shank area, apart from the one-time cold rolling requirement of this AD.

Instrument Panel Modifications

(c) If airplanes with propeller models ( )HC

– 2A which describes the application procedure. The Proposal

The FAA is considering an amendment to part 71 of the Federal Aviation Regulations (14 CFR part 71) to amend Class E airspace at Andrews

— Murphy, NC. A RNAV (GPS) RWY 8 SIAP has been developed for Andrews

— Murphy Airport, NC. Controlled airspace extending upward from 700 feet AGL is needed to accommodate the SIAP. Class E airspace designations for airspace areas extending upward from 700 feet or more above the surface are published in paragraph 6005 of FAA Order 7400.9J, dated August 31, 2001, and effective September 16, 2001, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document would be published subsequently in the Order.

The FAA has determined that the proposed regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore, (1) is not a ‘‘ significant regulatory action ’’ under Executive Order 12866; (2) is not a ‘‘ significant rule ’’ under DOT Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory Evaluation as the anticipated impact is so minimal. Since this is a routine matter that will only affect air traffic procedures and air navigation, it is certified that this rule, when promulgated, will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 71
