Download as PDF Federal Register / Vol. 84, No. 47 / Monday, March 11, 2019 / Rules and Regulations required by section 1403(b)(1) of the 2018 Farm Bill. AMS, therefore, is issuing this final rule without prior notice or public comment. Executive Orders 12866 and 13771 This rule has been determined to be not significant for purposes of Executive Order 12866, and therefore has not been reviewed by the Office of Management and Budget (OMB). In addition, because this rule does not meet the definition of a significant regulatory action, it does not trigger the requirements contained in Executive Order 13771. See OMB’s Memorandum titled ‘‘Interim Guidance Implementing Section 2 of the Executive Order of January 30, 2017, titled ‘Reducing Regulation and Controlling Regulatory Costs’’’ (February 2, 2017). amozie on DSK9F9SC42PROD with RULES Executive Order 12988 This rule has been reviewed under Executive Order 12988, Civil Justice Reform. It is not intended to have a retroactive effect. The amendment does not preempt any state or local laws, regulations, or policies, unless they present an irreconcilable conflict with this rule. Regulatory Flexibility Act and Paperwork Reduction Act Pursuant to the requirements set forth in the Regulatory Flexibility Act (RFA) (5 U.S.C. 601–612), the Agricultural Marketing Service (AMS) considered the economic impact of this action on small entities. Accordingly, AMS prepared this final regulatory flexibility analysis. The purpose of the RFA is to fit regulatory actions to the scale of businesses subject to such actions so that small businesses will not be unduly or disproportionately burdened. Small dairy farm businesses have been defined by the Small Business Administration (SBA) (13 CFR 121.601) as those businesses having annual gross receipts of less than $750,000. The SBA’s definition of small agricultural service firms, which includes handlers that are regulated under Federal milk marketing orders, varies depending on the product manufactured. Small fluid milk and ice cream manufacturers are defined as having 1,000 or fewer employees. Small butter and dry or condensed dairy product manufacturers are defined as having 750 or fewer employees. Small cheese manufacturers are defined as having 1,250 or fewer employees. Based on AMS data, the milk of 33,481 U.S. dairy farmers was pooled on the FMMO system for the month of May 2017. Of that total, AMS estimates that 32,958 dairy farmers, or 98 percent, would be considered small businesses. During the same month, 301 handler VerDate Sep<11>2014 17:17 Mar 08, 2019 Jkt 247001 plants were regulated by or reported their milk receipts to be pooled and priced under a FMMO. Of the total, AMS estimates approximately 163 handler plants, or 54 percent, would be considered small businesses. AMS does not expect the change in the Class I price formula to negatively impact small entities or impair their ability to compete in the marketplace. The change in the Class I price formula applies uniformly to both large and small businesses. The dairy industry has calculated that applying the ‘‘higher of’’ provisions to skim milk prices has returned a price $0.74 per hundredweight above the average of the two factors since the pricing formulas were implemented in 2000. Thus, the inclusion of the $0.74 in the calculation should make the change roughly revenue neutral. At the same time, it is anticipated that using the average of the Class III and Class IV advanced pricing factors in the Class I skim milk price formula will allow handlers to better manage volatility in monthly Class I skim milk prices using Class III milk and Class IV milk futures and options. Until now, uncertainty about which Class price will end up being higher each month has made effective hedging difficult. Amending the Class I skim milk price provisions may help small businesses better utilize currently available risk management tools. AMS is committed to complying with the E-Government Act, to promote the use of the internet and other information technologies to provide increased opportunities for citizen access to Government information and services, and for other purposes. A review of reporting requirements was completed under the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35). This final rule will have no impact on reporting, recordkeeping, or compliance requirements under the FMMOs because there are no changes to the current requirements. No new forms are added, and no additional reporting requirements are necessary. This final rule does not require additional information collection beyond that currently approved by OMB for FMMOs (OMB Number 0581–0032—Report Forms Under the Federal Milk Marketing Order Program).

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model BD–700–1A10 and BD–700–1A11 airplanes. The NPRM published in the Federal Register on August 16, 2018 (83 FR 40703). The NPRM was prompted by VerDate Sep<11>2014 17:17 Mar 08, 2019 Jkt 247001 in-service findings that a cotter pin at the main fitting joint of the NLG retraction actuator to the NLG strut showed evidence of shearing after an NLG retraction-extension cycling. The NPRM proposed to require revision of the existing maintenance or inspection program, as applicable, a general visual inspection for damage of a certain cotter pin present on certain configurations of the NLG strut assembly and for the modification number shown on the identification plate for the NLG strut, and modification of the NLG retraction actuator hardware on any damaged NLG strut assembly. We are issuing this AD to address shearing of the cotter pin at the main fitting joint of the NLG retraction actuator to the NLG strut, which could lead to a loss of hardware and result in an actuator disconnect and the NLG failing to retract or extend, or in an undamped freefall, which could adversely affect the airplane’s continued safe flight and landing. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2018–05, dated January 23, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model BD–700–1A10 and BD–700– 1A11 airplanes. The MCAI states: There have been in-service findings whereby the cotter pin at the retraction actuator to nose landing gear (NLG) strut main fitting was observed to be damaged after a NLG retraction-extension cycling. This condition could lead to a loss of hardware and result in an actuator disconnect resulting in a failure to retract or extend, or in an undamped freefall of the NLG [which could adversely affect the airplane’s continued safe flight and landing]. This [Canadian] AD mandates a revision to the approved maintenance schedule. This [Canadian] AD also mandates a visual inspection of the cotter pin for certain configurations of NLG strut assembly, and if found damaged, the incorporation of a modification which introduces a new castellated nut, spacer, end plate and sleeve to the NLG retraction actuator to main fitting joint. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0710. Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 Request To Clarify Effectivity of Inspection and Modification Requirements NetJets stated that they were not able to find paragraph 1.A, ‘‘Effectivity,’’ in the proposed AD, which was referenced in paragraph (h)(2) of the proposed AD. We infer from the commenter’s statement that they request the language in paragraph (h)(2) of the proposed AD be revised to clarify the reference to paragraph 1.A, ‘‘Effectivity.’’ We agree to clarify. Paragraph (h)(2) of the proposed AD directs operators to the applicable Bombardier service information specified in figure 2 to paragraph (h) of this AD. Each Bombardier service information referenced in figure 2 to paragraph (h) of this AD contains paragraph 1.A, ‘‘Effectivity,’’ which operators must use to determine the applicability of the actions required in paragraph (h)(1) to their specific airplane configuration. Paragraph 1.A, ‘‘Effectivity,’’ can be found in Paragraph 1, ‘‘Planning Information,’’ in the applicable Bombardier service information. We have not changed the AD in this regard. Request To Refer to New Service Information NetJets observed that the service information specified in figure 1 to paragraph (g) of the proposed AD is out of date and requested that we update those references to the latest revision. Netjets noted that at least one of the service bulletins has been revised since the NPRM was released. We agree with the request to refer to the latest service information, which adds a note to clarify the level at which time tracking of non-serialized parts should be done, and increases the interval at which certain inspections must be conducted. We have determined that the revised actions have no effect on airplanes on which the earlier actions were completed. Each service bulletin in figure 1 to paragraph (g) of the AD has been revised since the NPRM was released, and we have revised the preamble and figure 1 to paragraph (g) of this AD accordingly. We have coordinated this with TCCA. Because the revised service information does not include any additional actions, we have revised paragraph (j) of this AD to provide credit for specified actions performed before the effective date of this AD in accordance with Airworthiness Limitation (AWL) Task 32–33–01–111, ‘‘Restoration of the Nose Landing Gear Shock-Strut Assembly to RetractionActuator Main-Fitting Joint,’’ of Bombardier Global 5000 Time Limits/ E:\FR\FM\11MRR1.SGM 11MRR1 Federal Register / Vol. 84, No. 47 / Monday, March 11, 2019 / Rules and Regulations Maintenance Checks, Publication No. BD–700 TLMC, Revision 19, dated November 13, 2017; Bombardier Global 5000 Featuring Global Vision Flight Deck—Time Limits/Maintenance Checks, Publication No. GL 5000 GVFD, Revision 9, dated November 13, 2017; Bombardier Global 6000 Time Limits/ Maintenance Checks, Publication No. GL 6000 TLMC, Revision 9, dated November 13, 2017; Bombardier Global Express Time Limits/Maintenance Checks, Publication No. BD–700 TLMC, Revision 28, dated November 13, 2017; or Bombardier Global Express XRS Time Limits/Maintenance Checks, Publication No. BD–700 XRS TLMC, Revision 15, dated November 13, 2017; as applicable. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 Bombardier has issued the following service information, which describes procedures for a general visual inspection for damage of the cotter pin retaining the bolt that secures the main fitting joint of the NLG retraction actuator to the NLG strut and for the modification number shown on the identification plate for the NLG strut, and modification of the NLG retraction actuator hardware that secures the NLG retraction actuator to the NLG strut.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance We estimate that this AD affects 60 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $20,400 We have determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). We estimate the following costs to do the necessary on-condition action that would be required based on the results of any required actions. We have no way of determining the number of aircraft that might need this on-condition action: amozie on DSK9F9SC42PROD with RULES ESTIMATED COSTS OF ON-CONDITION ACTION Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 .......................................................................................................................... $10,847 $10,932 According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby VerDate Sep<11>2014 17:17 Mar 08, 2019 Jkt 247001 reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 result, we have included all known costs in our cost estimate. E:\FR\FM\11MRR1.SGM 11MRR1 8594 Federal Register / Vol. 84, No. 47 / Monday, March 11, 2019 / Rules and Regulations Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division. amozie on DSK9F9SC42PROD with RULES Regulatory Findings This AD will not have federalism implications under Executive Order 13132.

For the reasons discussed above, I certify that this AD: (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), (3) Will not affect intrastate aviation in Alaska, and (4) 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. (b) Affected ADs None. (c) Applicability This AD applies to Bombardier, Inc., Model BD–700–1A10 and BD–700–1A11 airplanes, certificated in any category, serial numbers 9002 through 9638 inclusive and 9998. (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. Adoption of the Amendment (e) Reason This AD was prompted by in-service findings that a cotter pin at the main fitting joint of the nose landing gear (NLG) retraction actuator to the NLG strut showed evidence of shearing after an NLG retractionextension cycling. We are issuing this AD to address this condition, which could lead to a loss of hardware and result in an actuator disconnect and the NLG failing to retract or extend, or in an undamped freefall, which could adversely affect the airplane’s continued safe flight and landing. Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: (f) Compliance Comply with this AD within the compliance times specified, unless already done. PART 39—AIRWORTHINESS DIRECTIVES (g) Maintenance or Inspection Program Revision Within 30 days after the effective date of this AD: Revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Airworthiness Limitation (AWL) Task 32– 33–01–111, ‘‘Restoration of the Nose Landing Gear Shock-Strut Assembly to RetractionActuator Main-Fitting Joint,’’ as specified in the applicable time limits/maintenance checks (TLMC) manual identified in figure 1 to paragraph (g) of this AD, as applicable.

ACTION: Final rule. AGENCY: We are superseding Airworthiness Directive (AD) 2016–07– 23, which applied to all Airbus SAS Model A318 and A319 series airplanes; Model A320–211, A320–212, A320–214, A320–216, A320–231, A320–232, and A320–233 airplanes; and Model A321– 111, A321–112, A321–131, A321–211, A321–212, A321–213, A321–231, and A321–232 airplanes. AD 2016–07–23 required, for certain airplanes, repetitive replacements of the fixed fairing upper and lower attachment studs of both the left-hand (LH) and right-hand (RH) main landing gear (MLG); and repetitive inspections for corrosion, wear, fatigue cracking, and loose studs of each forward stud assembly of the fixed fairing door upper and lower forward attachments of both the LH and RH MLG; and replacement if necessary. AD 2016–07–23 also provided an optional terminating modification for the repetitive replacements of the fixed fairing upper and lower attachment studs. This AD retains the requirements of AD 2016–07–23 and, for certain airplanes, requires re-identification of the LH and RH MLG fixed fairing assemblies’ part numbers. This AD was prompted by a determination that for some airplane configurations, associated fixed fairing assembly part numbers susceptible to fatigue cracking were not listed in certain service information required by AD 2016–07–23. In addition, we have determined that additional work is necessary to reidentify the fixed fairing assembly part SUMMARY: E:\FR\FM\11MRR1.SGM 11MRR1

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This AD 
was prompted by in-service findings that a cotter pin at the main 
fitting joint of the nose landing gear (NLG) retraction actuator to the 
NLG strut showed evidence of shearing after an NLG retraction-extension 
cycling. This AD requires revision of the existing maintenance or 
inspection program, as applicable, a general visual inspection for 
damage of a certain cotter pin present on certain configurations of the 
NLG strut assembly and for the

[[Page 8592]]

modification number shown on the identification plate for the NLG 
strut, and modification of the NLG retraction actuator hardware on any 
damaged NLG strut assembly. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective April 15, 2019.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Bombardier, Inc., 
Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the 
Federal Register on August 16, 2018 (83 FR 40703). The NPRM was 
prompted by in-service findings that a cotter pin at the main fitting 
joint of the NLG retraction actuator to the NLG strut showed evidence 
of shearing after an NLG retraction-extension cycling. The NPRM 
proposed to require revision of the existing maintenance or inspection 
program, as applicable, a general visual inspection for damage of a 
certain cotter pin present on certain configurations of the NLG strut 
assembly and for the modification number shown on the identification 
plate for the NLG strut, and modification of the NLG retraction 
actuator hardware on any damaged NLG strut assembly.
    We are issuing this AD to address shearing of the cotter pin at the 
main fitting joint of the NLG retraction actuator to the NLG strut, 
which could lead to a loss of hardware and result in an actuator 
disconnect and the NLG failing to retract or extend, or in an undamped 
freefall, which could adversely affect the airplane's continued safe 
flight and landing.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2018-05, dated January 
23, 2018 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-
1A11 airplanes. The MCAI states:

    There have been in-service findings whereby the cotter pin at 
the retraction actuator to nose landing gear (NLG) strut main 
fitting was observed to be damaged after a NLG retraction-extension 
cycling. This condition could lead to a loss of hardware and result 
in an actuator disconnect resulting in a failure to retract or 
extend, or in an undamped freefall of the NLG [which could adversely 
affect the airplane's continued safe flight and landing].
    This [Canadian] AD mandates a revision to the approved 
maintenance schedule. This [Canadian] AD also mandates a visual 
inspection of the cotter pin for certain configurations of NLG strut 
assembly, and if found damaged, the incorporation of a modification 
which introduces a new castellated nut, spacer, end plate and sleeve 
to the NLG retraction actuator to main fitting joint.

    You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0710.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Request To Clarify Effectivity of Inspection and Modification 
Requirements

    NetJets stated that they were not able to find paragraph 1.A, 
``Effectivity,'' in the proposed AD, which was referenced in paragraph 
(h)(2) of the proposed AD.
    We infer from the commenter's statement that they request the 
language in paragraph (h)(2) of the proposed AD be revised to clarify 
the reference to paragraph 1.A, ``Effectivity.'' We agree to clarify. 
Paragraph (h)(2) of the proposed AD directs operators to the applicable 
Bombardier service information specified in figure 2 to paragraph (h) 
of this AD. Each Bombardier service information referenced in figure 2 
to paragraph (h) of this AD contains paragraph 1.A, ``Effectivity,'' 
which operators must use to determine the applicability of the actions 
required in paragraph (h)(1) to their specific airplane configuration. 
Paragraph 1.A, ``Effectivity,'' can be found in Paragraph 1, ``Planning 
Information,'' in the applicable Bombardier service information. We 
have not changed the AD in this regard.

Request To Refer to New Service Information

    NetJets observed that the service information specified in figure 1 
to paragraph (g) of the proposed AD is out of date and requested that 
we update those references to the latest revision. Netjets noted that 
at least one of the service bulletins has been revised since the NPRM 
was released.
    We agree with the request to refer to the latest service 
information, which adds a note to clarify the level at which time 
tracking of non-serialized parts should be done, and increases the 
interval at which certain inspections must be conducted. We have 
determined that the revised actions have no effect on airplanes on 
which the earlier actions were completed. Each service bulletin in 
figure 1 to paragraph (g) of the AD has been revised since the NPRM was 
released, and we have revised the preamble and figure 1 to paragraph 
(g) of this AD accordingly. We have coordinated this with TCCA.
    Because the revised service information does not include any 
additional actions, we have revised paragraph (j) of this AD to provide 
credit for specified actions performed before the effective date of 
this AD in accordance with Airworthiness Limitation (AWL) Task 32-33-
01-111, ``Restoration of the Nose Landing Gear Shock-Strut Assembly to 
Retraction-Actuator Main-Fitting Joint,'' of Bombardier Global 5000

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule with the changes described previously and minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Costs of Compliance

    We estimate that this AD affects 60 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
4 work-hours x $85 per hour = $340...........................              $0             $340          $20,400
----------------------------------------------------------------------------------------------------------------

    We have determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although we recognize that this number may vary from operator to 
operator. In the past, we have estimated that this action takes 1 work-
hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), we have 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, we estimate the total cost per operator 
to be $7,650 (90 work-hours x $85 per work-hour).
    We estimate the following costs to do the necessary on-condition 
action that would be required based on the results of any required 
actions. We have no way of determining the number of aircraft that 
might need this on-condition action:

                                     Estimated Costs of On-Condition Action
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                                  Labor cost                                       Parts cost        product
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85..............................................         $10,847          $10,932
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all known costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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.
    For the reasons discussed above, I certify that this AD:
    (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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

condition, which could lead to a loss of hardware and result in an 
actuator disconnect and the NLG failing to retract or extend, or in 
an undamped freefall, which could adversely affect the airplane's 
continued safe flight and landing.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Maintenance or Inspection Program Revision

    Within 30 days after the effective date of this AD: Revise the 
existing maintenance or inspection program, as applicable, to 
incorporate the information specified in Airworthiness Limitation 
(AWL) Task 32-33-01-111, ``Restoration of the Nose Landing Gear 
Shock-Strut Assembly to Retraction-Actuator Main-Fitting Joint,'' as 
specified in the applicable time limits/maintenance checks (TLMC) 
manual identified in figure 1 to paragraph (g) of this AD, as 
applicable. The initial compliance time for doing the task is at the 
time specified in the applicable TLMC manual listed in figure 1 to
