RIN 2120-AA64
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.
