[Docket No. FAA-2017-1120; Product Identifier 2017-CE-030-AD]
RIN 2120-AA64


Airworthiness Directives; Textron Aviation Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Textron Aviation Inc. Models 510, 680, and 680A airplanes 
equipped with certain part number brake assemblies. This proposed AD 
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. This proposed AD would require inspection of 
the brake pad wear indicator pins and replacement of the brake assembly 
if any pin is set incorrectly. We are proposing this AD to address the 
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by January 25, 
2018.

Discussion

    We received information from UTC Aerospace Systems (UTC) that brake 
pad wear indicator pins were set incorrectly on 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. 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.

Related Service Information Under 1 CFR Part 51

    We reviewed UTC Service Bulletin 2-1706-1-32-1, Revision 1, dated 
July 18, 2017; and UTC 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 service bulletins are included 
as attachments to the Textron service letters.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

[[Page 58141]]

Costs of Compliance

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

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

 for Model 510.
----------------------------------------------------------------------------------------------------------------

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

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

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

    According to the manufacturer, the costs of this proposed 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 and domestic 
business jet transport airplanes to the Director of the Policy and 
Innovation Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD 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.
    For the reasons discussed above, I certify 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),
    (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 bulletins directly from UTC using the contact

[[Page 58142]]

information found in paragraph (k)(2) of this AD.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 32, Landing Gear.

(e) Unsafe Condition

    This AD was prompted by information received from UTC that brake 
pad wear indicator pins were set incorrectly. We are issuing this AD 
to detect and correct wear indicator pins that were set at an 
incorrect length. The unsafe 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.

(f) Compliance

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

(g) Inspection

    (1) For Model 510 airplanes: Within 75 landings after the 
effective date of this AD or within 90 days after the effective date 
of this AD, whichever occurs first, inspect the brake pad wear 
indicator pins, P/N 2-1706-1, for correct length following UTC 
Service Bulletin 2-1706-1-32-1, Revision 1, July 18, 2017.
    (2) For Models 680 and 680A airplanes: Within 200 landings after 
the effective date of this AD or within 90 days after the effective 
date of this AD, whichever occurs first, inspect the brake pad wear 
indicator pins, P/N 2-1675-1, for correct length following UTC 
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.

(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 for FAA-approved 
replacement instructions approved specifically for this AD. You may 
use the contact information listed in paragraph (k)(2) of this AD, 
as applicable.

(i) Special Flight Permit

    We allow a special flight permit per 14 CFR 39.23 for the 
replacement of the brake assembly required in paragraph (h) of this 
AD provided the wear indicator pin length extends a minimum of 0.200 
inches beyond the brake assembly housing with the brakes engaged.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Wichita ACO Branch, FAA, has the authority to 
approve AMOCs for this AD, if requested using the procedures found 
in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request 
to your principal inspector or local Flight Standards District 
Office, as appropriate. If sending information directly to the 
manager of the certification office, send it to the attention of the 
person identified in paragraph (k)(1) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
