Airworthiness Directives; The Boeing
Company Airplanes
Federal Aviation
Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
The Boeing Company Model 777–200
and –300 series airplanes equipped with
Rolls-Royce Trent 800 series engines.
This AD was prompted by reports of
heat damage to the strut aft fairing heat
shield primary seal, as well as heat and
wear damage to the heat shield
insulation blankets. This AD requires
repetitive inspections for cracks and
heat damage to the strut aft fairing lower
spar web structure (a flammable fluid
zone barrier), for wear to the heat shield
primary seal, and, as applicable, for heat
and wear damage to heat shield
insulation blankets; and related
investigative and corrective actions if
necessary. This AD also provides
optional terminating action for the
repetitive inspections. We are issuing
this AD to detect and correct cracks and
heat damage to the strut aft fairing lower
spar web structure (a flammable fluid
zone barrier), wear to the heat shield
primary seal, and heat and wear damage
to heat shield insulation blankets,
which could lead to through-cracks in
the aft fairing lower web structure and
heating of the aft fairing lower web
structure, and consequent uncontrolled
fire in the aft fairing, fuel tank ignition
or possible departure of the engine.
DATES: This AD is effective June 15,
2016.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of June 15, 2016.

Comments
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 777–200 and –300 series
airplanes equipped with Rolls-Royce
Trent 800 series engines. The NPRM
published in the Federal Register on
March 12, 2015 (80 FR 12954) (‘‘the
NPRM’’). The NPRM was prompted by
reports of heat damage to the strut aft
fairing heat shield primary seal, as well
as heat and wear damage to the heat
shield insulation blankets. The NPRM
proposed to require repetitive
inspections for cracks and heat damage
to the strut aft fairing lower spar web
structure (a flammable fluid zone
barrier), for wear to the heat shield
primary seal, and, as applicable, for heat
and wear damage to heat shield
insulation blankets; and related
investigative and corrective actions if
necessary. The NPRM also provided
VerDate Sep<11>2014
15:15 May 10, 2016
Jkt 238001
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. Marc
Philippi stated that he supports the
NPRM.
Request To Clarify Precipitating Event
and Unsafe Condition
Boeing requested that we revise the
and parts of the Discussion
section of the NPRM to clarify that we
received reports of heat damage to the
strut aft fairing heat shield primary seal
as well as heat and wear damage to the
heat shield insulation blankets. Boeing
also requested that we revise the
SUMMARY of the NPRM and paragraph (e)
of the proposed AD to clarify that the
unsafe condition could lead to throughcracks in the aft fairing lower web
structure and heating of the aft fairing
lower web structure. Boeing further
requested that we revise the Discussion
section of the NPRM to indicate that the
design of the strut aft fairing #1 heat
shield (a titanium pan casting) and #1
heat shield insulation blanket allows
hot turbulent gas from the exhaust
nozzle to cause wear and degradation of
the front face of the #1 insulation
blanket, enter the heat shield cavity (the
space or cavity between the heat shields
and insulation blankets), and contact
the strut aft fairing lower spar web
structure. Boeing additionally pointed
out that continuous exposure to hot
turbulent gas further damages the
primary seal and #1 insulation blanket,
increasing the temperature in the heat
shield cavity, and causes damage to the
insulation blankets and lower web
structure.
We agree that the requested changes
provide clarity about the unsafe
condition and consistency to the entire
AD, and have revised the SUMMARY of
this final rule and paragraph (e) of this
AD accordingly. However, the requested
revisions to the Discussion section of
the NPRM are not included since certain
SUMMARY
PO 00000
Frm 00010
Fmt 4700
Sfmt 4700
paragraphs of the Discussion section of
NPRMs are not restated in final rules.
Request To Remove References to the
Lower Spar Web Structure as a
Firewall
Boeing requested that we remove
references to the strut aft fairing lower
spar web structures as a firewall from
the preamble of the NPRM and
paragraph (e) of the proposed AD.
Boeing indicated that the strut aft fairing
lower spar web structure acts as a
flammable fluid zone barrier, not a
firewall. Boeing pointed out that a fire
zone is defined as a region where
flammable fluid and/or vapor leakage
can occur where there is an ignition
source present. Boeing also pointed out
that a flammable fluid leakage zone is
defined as an area in which flammable
fluid and/or vapor leakage can occur,
but where no ignition sources are
present, and that since there are no
ignition sources present in the strut aft
fairing cavity, The Boeing Company 777
strut fire protection document defines
the strut aft fairing cavity as a
flammable fluid leakage zone.
We agree with the commenter, and
have revised the preamble of this final
rule and paragraph (e) of this AD
accordingly.
Request To Include Information Notice
in the Final Rule
Air New Zealand (ANZ) requested
that we revise paragraph (h) of the
proposed AD to include reference to
Boeing Information Notice 777–54–0030
IN 01, dated April 7, 2015. ANZ pointed
out that Boeing Information Notice 777–
54–0030 IN 01, dated April 7, 2015,
includes a statement to clarify part
interchangeability and part
intermixability. ANZ also pointed out
that Boeing Service Bulletin 777–54–
0030, dated May 27, 2014, does not
include the statement to clarify part
interchangeability and part
intermixability and that the
modification included in the optional
terminating action could therefore
potentially be removed by installing
older design parts as specified in Boeing
Service Bulletin 777–54A0031, Revision
1, dated May 9, 2014. ANZ noted that
Boeing Information Notice 777–54–0030
IN 01, dated April 7, 2015, is not
approved by the FAA or any other
regulatory authority.
We acknowledge that Boeing
Information Notice 777–54–0030 IN 01,
dated April 7, 2015, contains the
updated part interchangeability and part
intermixability restriction statement for
certain parts (such as insulation
blankets). Boeing has issued Boeing
Service Bulletin 777–54–0030, Revision
E:\FR\FM\11MYR1.SGM
11MYR1
Federal Register / Vol. 81, No. 91 / Wednesday, May 11, 2016 / Rules and Regulations
jstallworth on DSK7TPTVN1PROD with RULES
1, dated September 30, 2015, which
contains the information specified in
Boeing Information Notice 777–54–0030
IN 01, dated April 7, 2015. Once an
airplane has been modified as specified
in Boeing Service Bulletin 777–54–
0030, dated May 27, 2014, or Boeing
Service Bulletin 777–54–0030, Revision
1, dated September 30, 2015 (optional
terminating action of installing
redesigned or newer insulation blankets,
and other associated parts), and the
operator has shown compliance with
paragraph (h)(1) of this AD, the
modification cannot be removed
without requesting approval of an
Alternative Method of Compliance
(AMOC). Any change to install the older
design parts would invalidate the
terminating action accomplished as
specified in Boeing Service Bulletin
777–54–0030, dated May 27, 2014, or
Boeing Service Bulletin 777–54–0030,
Revision 1, dated September 30, 2015.
Therefore, we have revised paragraph
(h)(1) of this AD to refer to Boeing
Service Bulletin 777–54–0030, Revision
1, dated September 30, 2015, and
provided credit for actions
accomplished using Boeing Service
Bulletin 777–54–0030, dated May 27,
2014, in paragraph (j)(2) of this AD.
ANZ stated that they believe the
AMOC statement in the impending
Airworthiness Notice should include
Boeing Information Notice 777–54–0030
IN 01, dated April 7, 2015. We infer that
ANZ is requesting an AMOC for that
information notice.
We disagree with giving AMOC
approval for Boeing Information Notice
777–54–0030 IN 01, dated April 7, 2015,
because we are requiring Boeing Service
Bulletin 777–54–0030, Revision 1, dated
September 30, 2015, that already
includes the information contained in
Boeing Information Notice 777–54–0030
IN 01, dated April 7, 2015.
Request for Revised Service
Information and Credit
ANZ requested that we revise
paragraph (j) of the proposed AD to
include credit for actions accomplished
as specified in Boeing Service Bulletin
777–54–0030, dated May 27, 2014. ANZ
pointed out that they have
accomplished the actions required by
paragraph (h)(1) of the proposed AD, on
multiple 777–200 airplanes in their
fleet, as specified in Boeing Service
Bulletin 777–54–0030, dated May 27,
2014. ANZ also stated that they believe
that credit for accomplishing the actions
required by paragraph (h)(1) of the
proposed AD, as specified in Boeing
Service Bulletin 777–54–0030, dated
May 27, 2014, should be added to
paragraph (j) of the proposed AD.
VerDate Sep<11>2014
15:15 May 10, 2016
Jkt 238001
We agree with the request to include
actions accomplished as specified in
Boeing Service Bulletin 777–54–0030,
dated May 27, 2014, in paragraph (j) of
this AD. Therefore, as stated previously,
we have revised this final rule to
provide credit for actions accomplished
using Boeing Service Bulletin 777–54–
0030, dated May 27, 2014, in paragraph
(j)(2) of this AD.
Request To Correct a Typographical
Error
Boeing requested that we correct a
typographical error by inserting missing
dollar signs in the Cost of Compliance
column of the On-Condition Costs table.
We agree and have revised this final
rule to include the missing information.
29121
2013, correctly show all nine insulation
blankets for doing the actions,
paragraph 2., ‘‘Material Information’’
only lists eight insulation blankets and
is missing part number 313W5421–29.
Therefore, we have clarified paragraph
(j)(1) of this AD to specify that credit for
previous actions are acceptable,
provided that insulation blanket part
number 313W5421–29 is inspected and
reinstalled, or replaced with a new
insulation blanket; as applicable, as
specified in the Accomplishment
Instructions of Boeing Alert Service
Bulletin 777–54A0031, dated June 7,
2013.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this AD
with the changes described previously
and 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.
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this AD.
Clarification of Actions
Boeing issued Information Notice
777–54A0031 IN 01, dated September
24, 2015, to clarify access information
when removing and installing pan
casting number 6. Information Notice
777–54A0031 IN 01, dated September
24, 2015, specifies that when removing
pan casting number 6 in FIGURE 9 and
FIGURE 10 of Boeing Service Bulletin
777–54A0031, Revision 1, dated May 9,
2014, it is acceptable to remove and
keep the bracket attached to the drain
lines or remove the P-clamps for access.
We refer to Boeing Service Bulletin 777–
54A0031, Revision 1, dated May 9,
2014, as the appropriate source of
service information for accomplishing
the actions required by paragraph (g) of
this AD. Note 12 in Paragraph 3.A.,
‘‘General Information,’’ of Boeing Alert
Service Bulletin 777–54A0031, dated
June 7, 2013; and Revision 1, dated May
9, 2014; contains statements informing
and permitting removal of more parts
for access when necessary. Also,
operators may have been performing
these same or similar access steps when
removing pan casting number 6. Thus,
the clarification in the information
notice is neither new nor additional
work. Further, this clarification of
access information is already included
in Boeing Service Bulletin 777–54–
0030, Revision 1, dated September 30,
2015, which is the appropriate source of
service information for accomplishing
the actions required by paragraph (h)(1)
of this AD. Therefore, we have
determined it is not necessary to
include reference to Information Notice
777–54A0031 IN 01, dated September
24, 2015, in the regulatory text of this
AD.

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.

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 777-200 and -300 series airplanes equipped with Rolls-Royce Trent
800 series engines. The NPRM published in the Federal Register on March
12, 2015 (80 FR 12954) (``the NPRM''). The NPRM was prompted by reports
of heat damage to the strut aft fairing heat shield primary seal, as
well as heat and wear damage to the heat shield insulation blankets.
The NPRM proposed to require repetitive inspections for cracks and heat
damage to the strut aft fairing lower spar web structure (a flammable
fluid zone barrier), for wear to the heat shield primary seal, and, as
applicable, for heat and wear damage to heat shield insulation
blankets; and related investigative and corrective actions if
necessary. The NPRM also provided optional terminating action for the
repetitive inspections. We are issuing this AD to detect and correct
cracks and heat damage to the strut aft fairing lower spar web
structure (a flammable fluid zone barrier), wear to the heat shield
primary seal, and heat and wear damage to heat shield insulation
blankets, which could lead to through-cracks in the aft fairing lower
web structure and heating of the aft fairing lower web structure, and
consequent uncontrolled fire in the aft fairing, fuel tank ignition or
possible departure of the engine.
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. Marc Philippi stated that he
supports the NPRM.
Request To Clarify Precipitating Event and Unsafe Condition
Boeing requested that we revise the SUMMARY and parts of the
Discussion section of the NPRM to clarify that we received reports of
heat damage to the strut aft fairing heat shield primary seal as well
as heat and wear damage to the heat shield insulation blankets. Boeing
also requested that we revise the SUMMARY of the NPRM and paragraph (e)
of the proposed AD to clarify that the unsafe condition could lead to
through-cracks in the aft fairing lower web structure and heating of
the aft fairing lower web structure. Boeing further requested that we
revise the Discussion section of the NPRM to indicate that the design
of the strut aft fairing #1 heat shield (a titanium pan casting) and #1
heat shield insulation blanket allows hot turbulent gas from the
exhaust nozzle to cause wear and degradation of the front face of the
#1 insulation blanket, enter the heat shield cavity (the space or
cavity between the heat shields and insulation blankets), and contact
the strut aft fairing lower spar web structure. Boeing additionally
pointed out that continuous exposure to hot turbulent gas further
damages the primary seal and #1 insulation blanket, increasing the
temperature in the heat shield cavity, and causes damage to the
insulation blankets and lower web structure.
We agree that the requested changes provide clarity about the
unsafe condition and consistency to the entire AD, and have revised the
SUMMARY of this final rule and paragraph (e) of this AD accordingly.
However, the requested revisions to the Discussion section of the NPRM
are not included since certain paragraphs of the Discussion section of
NPRMs are not restated in final rules.
Request To Remove References to the Lower Spar Web Structure as a
Firewall
Boeing requested that we remove references to the strut aft fairing
lower spar web structures as a firewall from the preamble of the NPRM
and paragraph (e) of the proposed AD. Boeing indicated that the strut
aft fairing lower spar web structure acts as a flammable fluid zone
barrier, not a firewall. Boeing pointed out that a fire zone is defined
as a region where flammable fluid and/or vapor leakage can occur where
there is an ignition source present. Boeing also pointed out that a
flammable fluid leakage zone is defined as an area in which flammable
fluid and/or vapor leakage can occur, but where no ignition sources are
present, and that since there are no ignition sources present in the
strut aft fairing cavity, The Boeing Company 777 strut fire protection
document defines the strut aft fairing cavity as a flammable fluid
leakage zone.
We agree with the commenter, and have revised the preamble of this
final rule and paragraph (e) of this AD accordingly.
Request To Include Information Notice in the Final Rule
Air New Zealand (ANZ) requested that we revise paragraph (h) of the
proposed AD to include reference to Boeing Information Notice 777-54-
0030 IN 01, dated April 7, 2015. ANZ pointed out that Boeing
Information Notice 777-54-0030 IN 01, dated April 7, 2015, includes a
statement to clarify part interchangeability and part intermixability.
ANZ also pointed out that Boeing Service Bulletin 777-54-0030, dated
May 27, 2014, does not include the statement to clarify part
interchangeability and part intermixability and that the modification
included in the optional terminating action could therefore potentially
be removed by installing older design parts as specified in Boeing
Service Bulletin 777-54A0031, Revision 1, dated May 9, 2014. ANZ noted
that Boeing Information Notice 777-54-0030 IN 01, dated April 7, 2015,
is not approved by the FAA or any other regulatory authority.
We acknowledge that Boeing Information Notice 777-54-0030 IN 01,
dated April 7, 2015, contains the updated part interchangeability and
part intermixability restriction statement for certain parts (such as
insulation blankets). Boeing has issued Boeing Service Bulletin 777-54-
0030, Revision
[[Page 29121]]
1, dated September 30, 2015, which contains the information specified
in Boeing Information Notice 777-54-0030 IN 01, dated April 7, 2015.
Once an airplane has been modified as specified in Boeing Service
Bulletin 777-54-0030, dated May 27, 2014, or Boeing Service Bulletin
777-54-0030, Revision 1, dated September 30, 2015 (optional terminating
action of installing redesigned or newer insulation blankets, and other
associated parts), and the operator has shown compliance with paragraph
(h)(1) of this AD, the modification cannot be removed without
requesting approval of an Alternative Method of Compliance (AMOC). Any
change to install the older design parts would invalidate the
terminating action accomplished as specified in Boeing Service Bulletin
777-54-0030, dated May 27, 2014, or Boeing Service Bulletin 777-54-
0030, Revision 1, dated September 30, 2015.
Therefore, we have revised paragraph (h)(1) of this AD to refer to
Boeing Service Bulletin 777-54-0030, Revision 1, dated September 30,
2015, and provided credit for actions accomplished using Boeing Service
Bulletin 777-54-0030, dated May 27, 2014, in paragraph (j)(2) of this
AD.
ANZ stated that they believe the AMOC statement in the impending
Airworthiness Notice should include Boeing Information Notice 777-54-
0030 IN 01, dated April 7, 2015. We infer that ANZ is requesting an
AMOC for that information notice.
We disagree with giving AMOC approval for Boeing Information Notice
777-54-0030 IN 01, dated April 7, 2015, because we are requiring Boeing
Service Bulletin 777-54-0030, Revision 1, dated September 30, 2015,
that already includes the information contained in Boeing Information
Notice 777-54-0030 IN 01, dated April 7, 2015.
Request for Revised Service Information and Credit
ANZ requested that we revise paragraph (j) of the proposed AD to
include credit for actions accomplished as specified in Boeing Service
Bulletin 777-54-0030, dated May 27, 2014. ANZ pointed out that they
have accomplished the actions required by paragraph (h)(1) of the
proposed AD, on multiple 777-200 airplanes in their fleet, as specified
in Boeing Service Bulletin 777-54-0030, dated May 27, 2014. ANZ also
stated that they believe that credit for accomplishing the actions
required by paragraph (h)(1) of the proposed AD, as specified in Boeing
Service Bulletin 777-54-0030, dated May 27, 2014, should be added to
paragraph (j) of the proposed AD.
We agree with the request to include actions accomplished as
specified in Boeing Service Bulletin 777-54-0030, dated May 27, 2014,
in paragraph (j) of this AD. Therefore, as stated previously, we have
revised this final rule to provide credit for actions accomplished
using Boeing Service Bulletin 777-54-0030, dated May 27, 2014, in
paragraph (j)(2) of this AD.
Request To Correct a Typographical Error
Boeing requested that we correct a typographical error by inserting
missing dollar signs in the Cost of Compliance column of the On-
Condition Costs table.
We agree and have revised this final rule to include the missing
information.
Clarification of Actions
Boeing issued Information Notice 777-54A0031 IN 01, dated September
24, 2015, to clarify access information when removing and installing
pan casting number 6. Information Notice 777-54A0031 IN 01, dated
September 24, 2015, specifies that when removing pan casting number 6
in FIGURE 9 and FIGURE 10 of Boeing Service Bulletin 777-54A0031,
Revision 1, dated May 9, 2014, it is acceptable to remove and keep the
bracket attached to the drain lines or remove the P-clamps for access.
We refer to Boeing Service Bulletin 777-54A0031, Revision 1, dated May
9, 2014, as the appropriate source of service information for
accomplishing the actions required by paragraph (g) of this AD. Note 12
in Paragraph 3.A., ``General Information,'' of Boeing Alert Service
Bulletin 777-54A0031, dated June 7, 2013; and Revision 1, dated May 9,
2014; contains statements informing and permitting removal of more
parts for access when necessary. Also, operators may have been
performing these same or similar access steps when removing pan casting
number 6. Thus, the clarification in the information notice is neither
new nor additional work. Further, this clarification of access
information is already included in Boeing Service Bulletin 777-54-0030,
Revision 1, dated September 30, 2015, which is the appropriate source
of service information for accomplishing the actions required by
paragraph (h)(1) of this AD. Therefore, we have determined it is not
necessary to include reference to Information Notice 777-54A0031 IN 01,
dated September 24, 2015, in the regulatory text of this AD.
Clarification of Credit
Although the Accomplishment Instructions of Boeing Alert Service
Bulletin 777-54A0031, dated June 7, 2013, correctly show all nine
insulation blankets for doing the actions, paragraph 2., ``Material
Information'' only lists eight insulation blankets and is missing part
number 313W5421-29. Therefore, we have clarified paragraph (j)(1) of
this AD to specify that credit for previous actions are acceptable,
provided that insulation blanket part number 313W5421-29 is inspected
and reinstalled, or replaced with a new insulation blanket; as
applicable, as specified in the Accomplishment Instructions of Boeing
Alert Service Bulletin 777-54A0031, dated June 7, 2013.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and 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.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Related Service Information Under 1 CFR Part 51
We reviewed the following service information:
Boeing Service Bulletin 777-54A0031, Revision 1, dated May
9, 2014.
Boeing Service Bulletin 777-54-0030, Revision 1, dated
September 30, 2015.
The service information describes procedures for repetitive
inspections for heat damage to the strut aft fairing lower spar web
structure (a flammable fluid zone barrier) and heat shield primary
seal, and heat and wear damage to heat shield insulation blankets; and
related investigative and corrective actions. 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 57 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
[[Page 29122]]

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

$9,350.
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, some of 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.
Regulatory Findings
