Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

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.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of 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 http://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 
Time Limits/

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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> 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.
