SUPPLEMENTARY INFORMATION: E:\FR\FM\01AUR1.SGM 01AUR1 Federal Register / Vol. 82, No. 146 / Tuesday, August 1, 2017 / Rules and Regulations Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB–135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. The NPRM published in the Federal Register on April 20, 2017 (82 FR 18590) (‘‘the NPRM’’). ˆ The Agencia Nacional de Aviacao ¸˜ Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian Airworthiness Directive 2016–07–01, dated July 18, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB–135ER, –135KE, –135KL, –135LR, –145, –145ER, –145MR, –145LR, –145XR, –145MP, and –145EP airplanes. The MCAI states: ANAC was informed about occurrences in which airplanes that incorporated SB 145– 27–0115, which changes the Gust Lock lever format, managed to takeoff, or performed [rejected take-offs] RTOs, in such a configuration that the Gust Lock lever prevented the thrust levers full excursion, thus limiting the engine power to about 70% of the nominal takeoff power. Analyses and simulations conducted by the manufacturer confirmed this as a possible scenario in case some verification procedures prior to and during takeoff, for whatever reason, are not properly performed. After evaluation, the conclusion was that the incorporation of SB 145–27–0115 would take away an important tactile cue regarding the thrust levers position, which, in a timely manner, would alert the crew of an improper takeoff configuration. During takeoffs, or attempts thereof, in such condition, the airplane would have a reduced performance, which would increase the required takeoff distance or the RTO distance, and reduce the airplane capacity to clear obstacles. Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this [Brazilian] AD in the indicated time limit. Required actions include replacing a certain gust lock lever. 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–2017– 0250. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the NPRM and the FAA’s response to that comment. Request To Revise the Compliance Time Air Line Pilots Association, International (ALPA) requested that the compliance time in the NPRM be revised. ALPA stated that since the Embraer service information was published 19 months prior, operators have been provided ample time to perform inspections to determine whether a corrective action is required. ALPA commented that, therefore, it is in partial support of the NPRM and suggested an inspection compliance time of 12 months or 2,500 flight hours after the effective date of the AD, and a repair compliance time of 24 months or 5,000 hours after the effective date of the AD. We disagree with the commenter’s request. In developing an appropriate compliance time, we considered the safety implications, parts availability, and normal maintenance schedules for timely accomplishment of inspecting and replacing the gust lock lever. Further, we arrived at the proposed compliance time with operator and manufacturer concurrence. Since the actions specified in the Brazilian AD and service information are not mandatory in the U.S., the FAA must issue a final rule to mandate those actions in order to address the identified unsafe condition. In consideration of all 35639 of these factors, we determined that the compliance time, as proposed, represents an appropriate time in which the gust lock lever can be inspected and replaced in a timely manner within the fleet, while still maintaining an adequate level of safety. We have not changed this AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 We have reviewed Embraer Service Bulletin 145–27–0126, dated October 6, 2015. This service information describes procedures for replacement of a certain gust lock lever for one with an alternative format. We have also reviewed Embraer Service Bulletin 145–27–0115, Revision 03, dated October 5, 2015. This service information describes modification procedures involving replacement of the gust lock lever with a new gust lock lever enabling both engine thrust levers to be advanced at the same angle as that of the electromechanical gust lock lever. 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 668 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Inspection ................................ mstockstill on DSK30JT082PROD with RULES Action 1 work-hour × $85 per hour = $85 .........................................

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. Regulatory Findings We determined that 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. mstockstill on DSK30JT082PROD with RULES List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: VerDate Sep<11>2014 17:30 Jul 31, 2017 Jkt 241001 Parts cost $6,315 Cost per product $6,400 PART 39—AIRWORTHINESS DIRECTIVES dated October 5, 2015, to determine whether the actions specified in Embraer Service Bulletin 145–27–0115 have been done. 1. The authority citation for part 39 continues to read as follows: (h) Corrective Action ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ 2017–15–16 Empresa Brasileira de Aeronautica S.A. (Embraer): Amendment 39–18976; FAA–2017–0250; Directorate Identifier 2016–NM–158–AD. (a) Effective Date This AD is effective September 5, 2017. (b) Affected ADs None. (c) Applicability This AD applies to all Empresa Brasileira de Aeronautica S.A.

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 The Boeing Company Model 787–9 airplanes. The NPRM published in the Federal Register on November 28, 2016 (81 FR 85448) (‘‘the NPRM’’). The NPRM was prompted by a determination that the shoulder bolt used on the outboard clevis of the forward support fitting of the RAT might not be long enough to allow for proper installation of the RAT; therefore, the clevis of the joint could be clamped together, resulting in reduced fatigue life and possible fracture of the clevis. The NPRM proposed to require inspecting for cracking of the clevis of the forward support fitting of the RAT, installing a longer shoulder bolt, and replacing the forward support fitting with a new fitting if any cracking is found. We are issuing this AD to prevent fracture of the clevis of the forward support fitting of the RAT, which could result in the RAT departing the airplane during a dual nonrestartable engine loss, and consequent loss of control of the airplane, or injury to maintenance crews during periodic RAT ground tests. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM Boeing and Ahmed Ahmed Hamdy concur with the content of the NPRM. E:\FR\FM\01AUR1.SGM 01AUR1

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Empresa Brasileira de 
Aeronautica S.A. (Embraer) Model EMB-135ER, -135KE, -135KL, -135LR, -
145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes. The 
NPRM published in the Federal Register on April 20, 2017 (82 FR 18590) 
(``the NPRM'').
    The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), 
which is the aviation authority for Brazil, has issued Brazilian 
Airworthiness Directive 2016-07-01, dated July 18, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Empresa 
Brasileira de Aeronautica S.A. (Embraer) Model EMB-135ER, -135KE, -
135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP 
airplanes. The MCAI states:

    ANAC was informed about occurrences in which airplanes that 
incorporated SB 145-27-0115, which changes the Gust Lock lever 
format, managed to takeoff, or performed [rejected take-offs] RTOs, 
in such a configuration that the Gust Lock lever prevented the 
thrust levers full excursion, thus limiting the engine power to 
about 70% of the nominal takeoff power. Analyses and simulations 
conducted by the manufacturer confirmed this as a possible scenario 
in case some verification procedures prior to and during takeoff, 
for whatever reason, are not properly performed. After evaluation, 
the conclusion was that the incorporation of SB 145-27-0115 would 
take away an important tactile cue regarding the thrust levers 
position, which, in a timely manner, would alert the crew of an 
improper takeoff configuration. During takeoffs, or attempts 
thereof, in such condition, the airplane would have a reduced 
performance, which would increase the required takeoff distance or 
the RTO distance, and reduce the airplane capacity to clear 
obstacles.
    Since this condition may occur in other airplanes of the same 
type and affects flight safety, a corrective action is required. 
Thus, sufficient reason exists to request compliance with this 
[Brazilian] AD in the indicated time limit.

Required actions include replacing a certain gust lock lever. 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-2017-
0250.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM and 
the FAA's response to that comment.

Request To Revise the Compliance Time

    Air Line Pilots Association, International (ALPA) requested that 
the compliance time in the NPRM be revised. ALPA stated that since the 
Embraer service information was published 19 months prior, operators 
have been provided ample time to perform inspections to determine 
whether a corrective action is required. ALPA commented that, 
therefore, it is in partial support of the NPRM and suggested an 
inspection compliance time of 12 months or 2,500 flight hours after the 
effective date of the AD, and a repair compliance time of 24 months or 
5,000 hours after the effective date of the AD.
    We disagree with the commenter's request. In developing an 
appropriate compliance time, we considered the safety implications, 
parts availability, and normal maintenance schedules for timely 
accomplishment of inspecting and replacing the gust lock lever. 
Further, we arrived at the proposed compliance time with operator and 
manufacturer concurrence. Since the actions specified in the Brazilian 
AD and service information are not mandatory in the U.S., the FAA must 
issue a final rule to mandate those actions in order to address the 
identified unsafe condition. In consideration of all of these factors, 
we determined that the compliance time, as proposed, represents an 
appropriate time in which the gust lock lever can be inspected and 
replaced in a timely manner within the fleet, while still maintaining 
an adequate level of safety. We have not changed this AD in this 
regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We have reviewed Embraer Service Bulletin 145-27-0126, dated 
October 6, 2015. This service information describes procedures for 
replacement of a certain gust lock lever for one with an alternative 
format.
    We have also reviewed Embraer Service Bulletin 145-27-0115, 
Revision 03, dated October 5, 2015. This service information describes 
modification procedures involving replacement of the gust lock lever 
with a new gust lock lever enabling both engine thrust levers to be 
advanced at the same angle as that of the electromechanical gust lock 
lever.
    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 668 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                      = $85.
----------------------------------------------------------------------------------------------------------------

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

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.

Regulatory Findings

    We determined that 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2017-15-16 Empresa Brasileira de Aeronautica S.A. (Embraer): 
Amendment 39-18976; FAA-2017-0250; Directorate Identifier 2016-NM-
158-AD.

(a) Effective Date

    This AD is effective September 5, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Empresa Brasileira de Aeronautica S.A. 
(Embraer) Model EMB-135ER, -135KE, -135KL, -135LR, -145, -145ER, -
145MR, -145LR, -145XR, -145MP, and -145EP airplanes, certificated in 
any category.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
controls.

(e) Reason

    This AD was prompted by a report of airplanes with modified gust 
lock levers that performed take-offs or rejected take-offs (RTOs), 
in such a configuration that the gust lock lever prevented the 
thrust lever's full excursion, thus limiting the engine power to 
about 70% of the nominal take-off power. We are issuing this AD to 
prevent incorrect configuration of the gust lock lever, which could 
reduce the airplane's performance during take-offs or attempted 
take-offs, increase the required take-off distance or the RTO 
distance, and reduce the airplane's capacity to clear obstacles.

(f) Compliance

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

(g) Inspection

    Within 5,000 flight hours or 24 months after the effective date 
of this AD, whichever occurs first: Check the airplane maintenance 
records to determine whether the actions specified in Embraer 
Service Bulletin 145-27-0115 have been done. If the records review 
is inconclusive, inspect the engine control box assembly against the 
Accomplishment Instructions of Embraer Service Bulletin 145-27-0115, 
Revision 03, dated October 5, 2015, to determine whether the actions 
specified in Embraer Service Bulletin 145-27-0115 have been done.

(h) Corrective Action

    If the check or inspection required by paragraph (g) of this AD 
indicates that the actions in Embraer Service Bulletin 145-27-0115 
have been done: Within 5,000 flight hours or 24 months after the 
effective date of this AD, whichever occurs first, replace the gust 
lock lever, in accordance with the Accomplishment Instructions of 
Embraer Service Bulletin 145-27-0126, dated October 6, 2015.

(i) Acceptable Alternative

    Modification of the airplane to a pre-modification condition 
(configuration before incorporating Embraer Service Bulletin 145-27-
0115), within the compliance times specified in paragraph (h) of 
this AD, in accordance with a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; 
or the Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC); 
or ANAC's authorized Designee, is acceptable for compliance with 
paragraph (h) of this AD.

(j) Prohibited Modification

    As of the effective date of this AD, do not accomplish the 
actions specified in Embraer Service Bulletin 145-27-0115 on any 
airplane.

(k) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, 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
