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 Textron Aviation 
Inc. (Textron) Models 510, 680, and 680A airplanes equipped with brake 
assemblies, part numbers (P/Ns) 2-1706-1 and 2-1675-1, with certain 
serial numbers. The NPRM published in the Federal Register on December 
11, 2017 (82 FR 58140). The NPRM was prompted by a report that brake 
pad wear indicator pins were set incorrectly, which could lead to brake 
pad wear beyond the acceptable limits without indication. Brakes 
overhauled by UTC may have wear indicator pins set longer than 
specified. UTC discovered this condition during their inspection of 
incoming brakes. This condition, if not corrected, could result in 
brake pad wear beyond the acceptable limits without indication and 
consequent loss of braking ability, which could lead to a runway 
excursion. We are issuing this AD to address the unsafe condition on 
these products.

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 Clarification for FAA-Approved Replacement Instructions

    Mark Mitcheson of NetJets Aviation requested specifics on ``FAA-
approved replacement instructions approved specifically for this AD.'' 
We infer he wants clarification of the intent of this statement.
    We agree that the language quoted by the commenter and used in the 
NPRM was confusing. We intended to direct those responsible for 
complying with the requirements of the AD to the type certificate 
holder, in this case Textron Aviation Inc., to obtain the replacement 
instructions (i.e., maintenance manuals) specific to the applicable 
airplane models affected by this AD.
    We modified in this AD the language quoted by the commenter to more 
accurately reflect our intent.

Request Parts Installation Prohibition

    Mark Mitcheson requested whether the AD should prohibit the 
installation of the affected parts.
    We partially agree. We agree operators should avoid installing the 
affected part because parts that do not meet type design could 
introduce the unsafe condition onto the airplane. However, we disagree 
with adding a specific requirement to the AD prohibiting the 
installation of the affected part. This AD requires inspection of the 
installed affected parts, and, if an affected part is installed, the 
airplane will immediately be subject to the requirements of this AD.

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 change described previously and minor 
editorial changes. We have determined that these changes:
     [Agr]re 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

    We reviewed UTC Aerospace Systems Service Bulletin 2-1706-1-32-1, 
Revision 1, dated July 18, 2017; and UTC Aerospace Systems Service 
Bulletin 2-1675-32-2, Revision 1, dated July 18, 2017. For the 
applicable models, the service information identifies the affected 
serial number brake assemblies and describes procedures for inspecting 
the wear indicator pins. 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. These UTC service bulletins are included as 
attachments with the Textron service letters discussed in the Other 
Related Service Information paragraph.

Other Related Service Information

    We also reviewed Textron Aviation Inc. Service Letters SL510-32-08, 
SL680-32-15, and SL680A-32-05, all dated July 21, 2017. For the 
applicable airplane models, these service letters direct the operators 
to use Goodrich Service Bulletins 2-1706-1-32-1 and 2-1675-32-2. 
However, the Goodrich Service Bulletins that the Textron Aviation Inc. 
Service Letters refer to and intend for operators to use are titled UTC 
Aerospace Systems Service Bulletin 2-1706-1-32-1, Revision 1, dated 
July 18, 2017; and UTC Aerospace Systems Service Bulletin 2-1675-32-2, 
Revision 1, dated July 18, 2017. The UTC Aerospace Systems service 
bulletins are included as attachments to the Textron service letters.

Costs of Compliance

    We estimate that this AD affects 668 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

 510.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacement 
that would be required based on the results of the inspection. We have 
no way of determining the number of airplanes that might need these 
replacements:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per

Replacement of the brake assembly for        8 work-hours x $85 per hour = $680.        $106,164        $106,844
 Models 680 and 680A.
Replacement of the brake assembly for Model  3 work-hours x $85 per hour = $255.          10,828          11,083
 510.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, 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 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 small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
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 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.

Service Bulletin 2-1675-32-2, Revision 1, July 18, 2017.
    (3) The compliance times in this AD are presented in landings. 
If you do not keep a record of the total number of landings, then 
multiply the total number of hours time-in-service (TIS) after the 
effective date by 0.85 for Model 510 airplanes and multiply the 
total number of hours TIS after the effective date by 0.73 for 
Models 680 and 680A airplanes to estimate the number of landings.
    (4) UTC Service Bulletin 2-1706-1-32-1, Revision 1, July 18, 
2017, and UTC Service Bulletin 2-1675-32-2, Revision 1, July 18, 
2017, both contain a requirement to complete an attached form and 
return the form to UTC Aerospace Systems. This AD does not require 
completing the attached form and returning it to UTC Aerospace 
Systems.

(h) Replacement

    If any brake pad wear indicator pin is found to have an 
incorrect length during the inspection required in paragraph (g) of 
this AD, before further flight, contact Textron Aviation, Inc. for 
replacement instructions that the FAA accepted for compliance with 
this AD. You may use the contact information listed in paragraph 
(l)(3) of this AD, as applicable.
