For the reasons discussed above, I certify this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ 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): ■ The Boeing Company: Docket No. FAA– 2019–0583; Product Identifier 2019– NM–063–AD. (a) Comments Due Date The FAA must receive comments by September 23, 2019. (b) Affected ADs None. khammond on DSKBBV9HB2PROD with PROPOSALS (c) Applicability This AD applies to The Boeing Company Model 787–8 airplanes, certificated in any category, as identified in Boeing Alert Requirements Bulletin B787–81205– SB570036–00 RB, Issue 001, dated December 14, 2018. (d) Subject Air Transport Association (ATA) of America Code 57, Wings. (e) Unsafe Condition This AD was prompted by a report of an escapement from the wing spar terminal fitting supplier indicating that the engineering requirements provided by Boeing for controlling machine mismatch were incorrect for part faying surfaces, which can result in a reduced fatigue capability at the interface of the side of body (SOB) rib.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2010–26–01, which applies to certain The Boeing Company Model 777–200 series airplanes. AD 2010–26–01 requires installing a new insulation blanket on the latch beam firewall of each thrust reverser (T/R) half. Since AD 2010–26–01 was issued, the agency received a report that the T/R affected by AD 2010–26–01 has the potential to be installed on airplanes outside of the applicability of that AD. This proposed AD would retain the requirements of 2010–26–01. This proposed AD would also add airplanes to the applicability. For those airplanes, this proposed AD would require an inspection to determine if the installed T/R has an affected part number and, if an affected part number is found, installation of a new insulation blanket. The FAA is proposing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2019–0602; Product Identifier 2019–NM–016–AD’’ at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this NPRM. The FAA will consider all comments received by the closing date and may amend this NPRM because of those comments. The FAA will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion The FAA issued AD 2010–26–01, Amendment 39–16540 (75 FR 78594, December 16, 2010) (‘‘AD 2010–26– 01’’), for certain Model 777–200 series airplanes. AD 2010–26–01 requires installing a new insulation blanket on the latch beam firewall of each T/R half. AD 2010–26–01 resulted from an inflight shutdown due to an engine fire indication; an under-cowl engine fire was extinguished after landing. We issued AD 2010–26–01 to prevent a fire from entering the cowl or strut area, which could weaken T/R parts and result in reduced structural integrity of the T/R, possible separation of T/R parts during flight, and consequent damage to the airplane and injury to people or damage to property on the ground. Actions Since AD 2010–26–01 Was Issued Since AD 2010–26–01 was issued, the agency received a report that the T/R affected by AD 2010–26–01 has the potential to be installed on airplanes outside of the applicability of that AD. Therefore, the applicability in this proposed AD has been revised to specify The Boeing Company Model 777–200 series airplanes, equipped with General Electric Company (GE) GE90–76B, –85B, –90B, or –94B engines. Related Service Information Under 1 CFR Part 51 The FAA reviewed Boeing Service Bulletin 777–78A0066, Revision 3, dated April 28, 2011. This service information describes procedures for installing a new insulation blanket on the latch beam firewall of each T/R half. The installation includes, for certain airplanes, inspecting to determine if fitting part number 315W1436–4 is installed on the aft latch beam of the right side T/R and, for affected fittings, cutting the clevis from the affected fitting. This proposed AD would also require Boeing Alert Service Bulletin 777– 78A0066, Revision 2, dated April 8, 2010, which the Director of the Federal Register approved for incorporation by reference as of January 20, 2011 (75 FR 78594, December 16, 2010). 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. FAA’s Determination The FAA is proposing this AD because the agency 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 retain all requirements of AD 2010–26–01. This proposed AD would also add airplanes to the applicability. For those airplanes, this proposed AD would require an inspection to determine if the installed T/R has an affected part number and, if an affected part number is found, installation of a new insulation blanket. Costs of Compliance The FAA estimates that this proposed AD affects 25 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSKBBV9HB2PROD with PROPOSALS ESTIMATED COSTS Action Blanket installation (retained actions 7 work-hours × $85 per hour = $595 from AD 2010–26–01) (21 airplanes). Inspection and blanket installation Up to 13 work-hours × $85 per hour = (new proposed action) (4 airplanes). Up to $1,105.

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. The FAA is 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 proposed 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. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: khammond on DSKBBV9HB2PROD with PROPOSALS Regulatory Findings The FAA has 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 that the proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Will not affect intrastate aviation in Alaska, and (3) 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.

ACTION: Proposed rule. AGENCY: The Environmental Protection Agency (EPA) is proposing to revise certain New Source Review (NSR) applicability regulations to clarify the requirements that apply to sources proposing to undertake a physical or operational change (i.e., a project) under the NSR preconstruction permitting program. Under this program, an existing major source proposing to undertake a project must determine whether that project will constitute a major modification following a two-step applicability test and thus be subject to the NSR preconstruction permitting requirements. The first step is to determine if the proposed project will cause a ‘‘significant emissions increase’’ of a regulated NSR pollutant (Step 1). If the proposed project is projected to cause such an increase, the second step is to determine if there is a ‘‘significant net emissions increase’’ of that pollutant (Step 2). In this action, we are proposing to revise our NSR applicability regulations to make it clear that both emissions increases and emissions decreases that result from a given proposed project are to be considered at Step 1 of the NSR major modification applicability test. In addition, this proposal replaces and withdraws the agency’s 2006 Project Netting Proposal. DATES: SUMMARY: E:\FR\FM\09AUP1.SGM 09AUP1

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2010-26-01, which applies to certain The Boeing Company Model 777-200 
series airplanes. AD 2010-26-01 requires installing a new insulation 
blanket on the latch beam firewall of each thrust reverser (T/R) half. 
Since AD 2010-26-01 was issued, the agency received a report that the 
T/R affected by AD 2010-26-01 has the potential to be installed on 
airplanes outside of the applicability of that AD. This proposed AD 
would retain the requirements of 2010-26-01. This proposed AD would 
also add airplanes to the applicability. For those airplanes, this 
proposed AD would require an inspection to determine if the installed 
T/R has an affected part number and, if an affected part number is 
found, installation of a new insulation blanket. The FAA is proposing 
this AD to address the unsafe condition on these products.

Discussion

    The FAA issued AD 2010-26-01, Amendment 39-16540 (75 FR 78594, 
December 16, 2010) (``AD 2010-26-01''), for certain Model 777-200 
series airplanes. AD 2010-26-01 requires installing a new insulation 
blanket on the latch beam firewall of each T/R half. AD 2010-26-01 
resulted from an in-flight shutdown due to an engine fire indication; 
an under-cowl engine fire was extinguished after landing. We issued AD 
2010-26-01 to prevent a fire from entering the cowl or strut area, 
which could weaken T/R parts and result in reduced structural integrity 
of the T/R, possible separation of T/R parts during flight, and 
consequent damage to the airplane and injury to people or damage to 
property on the ground.

Actions Since AD 2010-26-01 Was Issued

    Since AD 2010-26-01 was issued, the agency received a report that 
the T/R affected by AD 2010-26-01 has the potential to be installed on 
airplanes outside of the applicability of that AD. Therefore, the 
applicability in this proposed AD has been revised to specify The 
Boeing Company Model 777-200 series airplanes, equipped with General 
Electric Company (GE) GE90-76B, -85B, -90B, or -94B engines.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Service Bulletin 777-78A0066, Revision 3, 
dated April 28, 2011. This service information describes procedures for 
installing a new insulation blanket on the latch beam firewall of each 
T/R half. The installation includes, for certain airplanes, inspecting 
to determine if fitting part number 315W1436-4 is installed on the aft 
latch beam of the right side T/R and, for affected fittings, cutting 
the clevis from the affected fitting.
    This proposed AD would also require Boeing Alert Service Bulletin 
777-78A0066, Revision 2, dated April 8, 2010, which the Director of the 
Federal Register approved for incorporation by reference as of January 
20, 2011 (75 FR 78594, December 16, 2010).
    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.

FAA's Determination

    The FAA is proposing this AD because the agency 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 retain all requirements of AD 2010-26-01. 
This proposed AD would also add airplanes to the applicability. For 
those airplanes, this proposed AD would require an inspection to 
determine if the installed T/R has an affected part number and, if an 
affected part number is found, installation of a new insulation 
blanket.

Costs of Compliance

    The FAA estimates that this proposed AD affects 25 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                                                     Estimated Costs

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.
    The FAA is 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 proposed 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

    The FAA has 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 that the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 removing Airworthiness Directive (AD) 
2010-26-01, Amendment 39-16540 (75 FR 78594, December 16, 2010), and 
adding the following new AD:

The Boeing Company: Docket No. FAA-2019-0602; Product Identifier 
2019-NM-016-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by September 23, 
2019.

(b) Affected ADs

    This AD replaces AD 2010-26-01, Amendment 39-16540 (75 FR 78594, 
December 16, 2010) (``AD 2010-26-01'').

(c) Applicability

    This AD applies to The Boeing Company Model 777-200 series 
airplanes, certificated in any category, equipped with General 
Electric Company (GE) GE90-76B, -85B, -90B, or -94B engines.

(d) Subject

    Air Transport Association (ATA) of America Code 78, Engine 
exhaust.

(e) Unsafe Condition

    This AD was prompted by a report of an in-flight shutdown due to 
an engine fire indication; an under-cowl engine fire was 
extinguished after landing and a determination that additional 
airplanes are affected. The FAA is issuing this AD to prevent a fire 
from entering the cowl or strut area, which could weaken thrust 
reverser (T/R) parts and result in reduced structural integrity of 
the T/R, possible separation of T/R parts during flight, and 
consequent damage to the airplane and injury to people or damage to 
property on the ground.

(f) Compliance

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

(g) Retained Installation of Insulation Blanket, With Revised Service 
Information

    This paragraph restates the requirements of paragraph (g) of AD 
2010-26-01, with revised service information. For airplanes 
identified in Boeing Alert Service Bulletin 777-78A0066, Revision 2, 
dated April 8, 2010: Within 60 months or 4,500 flight cycles after 
January 20, 2011 (the effective date of AD 2010-26-01), whichever is 
first, install a new insulation blanket on the latch beam firewall 
of each T/R half by doing all the applicable actions specified in 
the Accomplishment Instructions of Boeing Service Bulletin 777-
78A0066, Revision 3, dated April 28, 2011.

(h) New Requirement: Installation of Insulation Blanket for Additional 
Airplanes

    For airplanes not identified in paragraph (g) of this AD: Within 
60 months or 4,500 flight cycles after the effective date of this 
AD, whichever is first, inspect to determine if the installed T/R 
has any affected part number as identified in paragraphs (h)(1) 
through (h)(5) of this AD. If an affected T/R is found or if it 
cannot be determined which T/R is installed, within 60 months or 
4,500 flight cycles after the effective date of this AD, whichever 
is first, install a new insulation blanket on the latch beam 
firewall of each T/R half by doing all the applicable actions 
specified in the Accomplishment Instructions of Boeing Service 
Bulletin 777-78A0066, Revision 3, dated April 28, 2011, except as 
specified in paragraph (i) of this AD. A review of airplane 
maintenance records is acceptable in lieu of this inspection if it 
can be conclusively determined from that review that the installed 
T/R is not an affected T/R. A review of airplane maintenance records 
is also acceptable in lieu of this inspection if it can be 
conclusively determined from that review that an affected T/R is 
installed and the actions specified in Boeing Service Bulletin 777-
78A0066, Revision 3, dated April 28, 2011, have already been done on 
that T/R.
