SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017–15–04, Amendment 39–18964 (82 FR 33785, PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 July 21, 2017) (‘‘AD 2017–15–04’’). AD 2017–15–04 applied to certain The Boeing Company Model 787–8 and 787– 9 airplanes. The NPRM published in the Federal Register on July 2, 2019 (84 FR 31526). The NPRM was prompted by a determination that discrepant EMAs could be installed on airplanes outside the original applicability of AD 2017– 15–04. The NPRM proposed to continue to require replacement of affected EMAs. The NPRM also proposed to expand the applicability to include all The Boeing Company Model 787 series airplanes, and add a new requirement to identify, for certain airplanes, the part number of EMAs and to replace affected EMAs. The FAA is issuing this AD to address chafing and consequent wire damage that could result in a potential source of ignition in the flammable leakage zone and a consequent fire or explosion. Comments The FAA 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 United Airlines stated that it has no objection to the NPRM. Request To Withdraw the NPRM Boeing requested that the FAA withdraw the NPRM and retain AD 2017–15–04. Boeing stated that the proposal to expand the applicability to include all Boeing Model 787 series airplanes is not necessary. Boeing pointed out that discrepant spoiler EMAs are only applicable to Model 787–8 and 787–9 airplanes, which is the current applicability of AD 2017–15–04. Boeing further pointed out that the changes to the spoiler EMAs, as described in Boeing Service Bulletin B787–81205–SB270030–00, is the baseline for that model, and was incorporated in production on the first Model 787–10 airplane and on. Boeing also stated that the Illustrated Parts Data (IPD) defines the effectivity of the new spoiler EMA part numbers (P/Ns) by line number, and shows that only the C99144–006 P/N is allowed on Model 787–10 airplanes. Boeing asserted that all documentation available to operators specifically states that spoiler EMA P/N C99144–006 is the only approved P/N for Model 787–10 airplanes. The FAA does not agree with the request to withdraw the NPRM. EMAs are rotable parts that could later be installed on Boeing Model 787 series airplanes that previously did not have affected EMAs installed. Existing in- E:\FR\FM\06FER1.SGM 06FER1 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations effectivity of ‘‘all’’ would not be necessary to address this issue. At this time, however, AC 120–77 is approved FAA policy that provides certain flexibility for rotable parts. Therefore, the applicability of this AD remains all The Boeing Company Model 787 series airplanes. The FAA has not changed this AD in this regard. service maintenance practices allow for the possibility of discrepant parts being installed on Boeing Model 787 airplanes not affected by AD 2017–15–04. Therefore, the FAA included all Boeing Model 787 series airplanes in the applicability to ensure the unsafe condition is addressed if an affected EMA is installed on a Boeing Model 787–10 airplane. The FAA has not changed this AD in this regard. Request To Revise Summary and ‘‘Actions Since AD 2017–15–04 Was Issued’’ Section Request To Change Applicability of the NPRM Boeing acknowledges there is a difference between the Boeing service information and the NPRM in capturing airplane effectivity. Boeing noted that there may be instances where operators are rotating parts outside of type design, beyond effectivity limits, or installing EMAs onto airplane configurations in which service information and design changes have already been incorporated. Boeing stated it understands the FAA’s concerns regarding the possibility of parts being rotated outside the effectivity contained in the Boeing service information. As a result, Boeing expressed its desire to seek an alternative solution to address the concerns of the FAA. Boeing recommended a collaboration between airline partners, other original equipment manufacturers, and civil aviation authorities to develop an action to implement safe, fair, and consistent policy to address concerns on rotable parts for the industry. Boeing stated it seeks to implement an industrystandard policy on rotable parts. The FAA is aware that airlines want to maintain the flexibility that is reflected in FAA Advisory Circular (AC) 120–77, dated October 7, 2002 (see paragraph 11(a)(4) of AC 120–77). If this flexibility is no longer allowed with regard to rotable parts, then ADs with an Boeing requested that the FAA revise the wording in the SUMMARY from ‘‘. . . discrepant EMAs may have been installed on airplanes outside the original applicability . . .’’ to ‘‘. . . discrepant EMAs could be installed on airplanes outside the original applicability . . . .’’ Boeing reasoned that the wording in the NPRM implies that the FAA has indication that discrepant EMAs have been installed inservice. Boeing infers that the intent of the phrase in the SUMMARY is a hypothetical statement that discrepant EMAs could be installed, and this intent was stated more clearly in the ‘‘Actions Since AD 2017–15–04 Was Issued’’ section of the NPRM. The FAA partially agrees with the commenter’s request. The FAA agrees that the proposed wording more closely matches the intent of the wording in the ‘‘Actions Since AD 2017–15–04 Was Issued’’ section of the NPRM. However, since neither that section of the SUMMARY nor the ‘‘Actions Since AD 2017–15–04 Was Issued’’ section of the Discussion appear in the final rule, the FAA has not changed this final rule as requested. The FAA has, however, revised the statement of what prompted the AD in the Discussion section of this final rule to address the commenter’s request. 6739 Conclusion The FAA 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. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. The FAA 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 The FAA reviewed Boeing Alert Service Bulletin B787–81205– SB270030–00, Issue 002, dated April 7, 2017. The service information describes procedures for replacing affected EMAs with new EMAs. This AD also requires Boeing Service Bulletin B787–81205–SB270030–00, Issue 001, dated October 22, 2015, which the Director of the Federal Register approved for incorporation by reference as of August 25, 2017 (82 FR 33785, July 21, 2017). These documents are distinct since they apply to different airplanes. 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 The FAA estimates that this AD would affect 93 airplanes of U.S. registry. The agency estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Parts cost EMA replacement (retained actions from AD 2017–15– 04). Inspection/records check ....... 32 work-hours × $85 per hour = $2,720 per EMA replacement. 1 work-hour × $85 per hour = $85. Cost per product Cost on U.S. operators (*) $2,720 * per EMA replacement. $252,960 * per EMA replacement. $0 $85 per inspection cycle ........ $7,905. * Parts cost is not included in the service information, but Boeing has indicated that existing parts can be modified to become the new parts. lotter on DSKBCFDHB2PROD with RULES 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 VerDate Sep<11>2014 19:34 Feb 05, 2020 Jkt 250001 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 PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 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 E:\FR\FM\06FER1.SGM 06FER1 6740 Federal Register / Vol. 85, No. 25 / Thursday, February 6, 2020 / Rules and Regulations unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings The FAA has 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) 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.

PART 39—AIRWORTHINESS DIRECTIVES (c) Applicability This AD applies to all The Boeing Company Model 787 series airplanes, certificated in any category. This AD was prompted by wire harness chafing on the electro-mechanical actuators (EMAs) for certain spoilers due to insufficient separation with adjacent structure. The FAA is issuing this AD to address chafing and consequent wire damage that could result in a potential source of ignition in the flammable leakage zone and a consequent fire or explosion. (h) New Definition Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: § 39.13 (e) Unsafe Condition For airplanes not identified in paragraph (g) of this AD with an original airworthiness certificate or an original export certificate of airworthiness dated before or on the effective date of this AD, do the actions specified in paragraphs (i)(1) and (2) of this AD. (1) Within 40 months after the effective date of this AD, perform a general visual inspection of the EMAs for spoilers 4, 5, 10, and 11 to determine the part number. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the EMA can be conclusively determined from that review. (2) If the EMA is an affected part: Within 40 months after the effective date of this AD, replace the EMA in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin B787–81205–SB270030–00, Issue 002, dated April 7, 2017. (l) Alternative Methods of Compliance (AMOCs) (1) The Manager, Seattle 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 (m)(1) of this AD. Information may be emailed to: 9ANM-Seattle-ACO-AMOC-Requests@faa.gov. (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. (3) An AMOC that provides an acceptable level of safety may be used for any repair, modification, or alteration required by this AD if it is approved by The Boeing Company Organization Designation Authorization (ODA) that has been authorized by the Manager, Seattle ACO Branch, FAA, to make those findings. To be approved, the repair method, modification deviation, or alteration deviation must meet the certification basis of the airplane, and the approval must specifically refer to this AD. (4) AMOCs approved previously for AD 2017–15–04 are approved as AMOCs for the corresponding provisions of paragraph (g) of this AD. (5) For service information that contains steps that are labeled as Required for Compliance (RC), the provisions of paragraphs (l)(5)(i) and (ii) of this AD apply. (i) The steps labeled as RC, including substeps under an RC step and any figures identified in an RC step, must be done to comply with the AD. If a step or substep is labeled ‘‘RC Exempt,’’ then the RC requirement is removed from that step or substep. An AMOC is required for any deviations to RC steps, including substeps and identified figures. (ii) Steps not labeled as RC may be deviated from using accepted methods in accordance with the operator’s maintenance or inspection program without obtaining approval of an AMOC, provided the RC steps, including substeps and identified figures, can still be done as specified, and the airplane can be put back in an airworthy condition.

SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0312, dated December 20, 2019 (‘‘EASA AD 2019–0312’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A330–200 Freighter series airplanes; Model A330– 200 series airplanes; Model A330–300 series airplanes; Model A340–200 series airplanes; Model A340–300 series airplanes; Airbus SAS Model A340–541 and –542 airplanes; and Airbus SAS Model A340–642 and –643 airplanes. Model A340–542 and –643 airplanes are not certified by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. This AD was prompted by the absence of a requirement to remove certain Emergency Procedures relating to the undue activation of Alpha Protection (Alpha Prot) in the existing AFM after accomplishing the AFM revision specified in AD 2014–25–52, Amendment 39–18066 (80 FR 3161, January 22, 2015) (‘‘AD 2014–25–52’’). The FAA is issuing this AD to address this condition, which, under certain conditions, could lead to the incorrect application of the procedure by the flight crew, possibly resulting in increased flight crew workload and consequent reduced control of the airplane. See the MCAI for additional background information. Relationship Between This AD and AD 2014–25–52, AD 2016–12–15, Amendment 39–18564 (81 FR 40160, June 21, 2016) (‘‘AD 2016–12–15’’), and AD 2018–21–07, Amendment 39–19465 (83 FR 51825, October 15, 2018) (‘‘AD 2018–21–07’’) AD 2014–25–52 requires revising the AFM to incorporate procedures to advise the flight crew of emergency E:\FR\FM\06FER1.SGM 06FER1

04, which applied to certain The Boeing Company Model 787-8 and 787-9 
airplanes. AD 2017-15-04 required replacement of affected 
electromechanical actuators (EMAs). This AD retains the requirements of 
AD 2017-15-04; expands the applicability to include all The Boeing 
Company Model 787 series airplanes; and adds a new requirement to 
identify, for certain airplanes, the part number of EMAs and to replace 
affected EMAs. This AD was prompted by wire harness chafing on the EMAs 
for certain spoilers due to insufficient separation with adjacent 
structure. The FAA is issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective March 12, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 12, 
2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of August 
25, 2017 (82 FR 33785, July 21, 2017).

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2017-15-04, Amendment 39-18964 (82 FR 
33785, July 21, 2017) (``AD 2017-15-04''). AD 2017-15-04 applied to 
certain The Boeing Company Model 787-8 and 787-9 airplanes. The NPRM 
published in the Federal Register on July 2, 2019 (84 FR 31526). The 
NPRM was prompted by a determination that discrepant EMAs could be 
installed on airplanes outside the original applicability of AD 2017-
15-04. The NPRM proposed to continue to require replacement of affected 
EMAs. The NPRM also proposed to expand the applicability to include all 
The Boeing Company Model 787 series airplanes, and add a new 
requirement to identify, for certain airplanes, the part number of EMAs 
and to replace affected EMAs. The FAA is issuing this AD to address 
chafing and consequent wire damage that could result in a potential 
source of ignition in the flammable leakage zone and a consequent fire 
or explosion.

Comments

    The FAA 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

    United Airlines stated that it has no objection to the NPRM.

Request To Withdraw the NPRM

    Boeing requested that the FAA withdraw the NPRM and retain AD 2017-
15-04. Boeing stated that the proposal to expand the applicability to 
include all Boeing Model 787 series airplanes is not necessary. Boeing 
pointed out that discrepant spoiler EMAs are only applicable to Model 
787-8 and 787-9 airplanes, which is the current applicability of AD 
2017-15-04. Boeing further pointed out that the changes to the spoiler 
EMAs, as described in Boeing Service Bulletin B787-81205-SB270030-00, 
is the baseline for that model, and was incorporated in production on 
the first Model 787-10 airplane and on. Boeing also stated that the 
Illustrated Parts Data (IPD) defines the effectivity of the new spoiler 
EMA part numbers (P/Ns) by line number, and shows that only the C99144-
006 P/N is allowed on Model 787-10 airplanes. Boeing asserted that all 
documentation available to operators specifically states that spoiler 
EMA P/N C99144-006 is the only approved P/N for Model 787-10 airplanes.
    The FAA does not agree with the request to withdraw the NPRM. EMAs 
are rotable parts that could later be installed on Boeing Model 787 
series airplanes that previously did not have affected EMAs installed. 
Existing in-

[[Page 6739]]

service maintenance practices allow for the possibility of discrepant 
parts being installed on Boeing Model 787 airplanes not affected by AD 
2017-15-04. Therefore, the FAA included all Boeing Model 787 series 
airplanes in the applicability to ensure the unsafe condition is 
addressed if an affected EMA is installed on a Boeing Model 787-10 
airplane. The FAA has not changed this AD in this regard.

Request To Change Applicability of the NPRM

    Boeing acknowledges there is a difference between the Boeing 
service information and the NPRM in capturing airplane effectivity. 
Boeing noted that there may be instances where operators are rotating 
parts outside of type design, beyond effectivity limits, or installing 
EMAs onto airplane configurations in which service information and 
design changes have already been incorporated. Boeing stated it 
understands the FAA's concerns regarding the possibility of parts being 
rotated outside the effectivity contained in the Boeing service 
information. As a result, Boeing expressed its desire to seek an 
alternative solution to address the concerns of the FAA. Boeing 
recommended a collaboration between airline partners, other original 
equipment manufacturers, and civil aviation authorities to develop an 
action to implement safe, fair, and consistent policy to address 
concerns on rotable parts for the industry. Boeing stated it seeks to 
implement an industry-standard policy on rotable parts.
    The FAA is aware that airlines want to maintain the flexibility 
that is reflected in FAA Advisory Circular (AC) 120-77, dated October 
7, 2002 (see paragraph 11(a)(4) of AC 120-77). If this flexibility is 
no longer allowed with regard to rotable parts, then ADs with an 
effectivity of ``all'' would not be necessary to address this issue. At 
this time, however, AC 120-77 is approved FAA policy that provides 
certain flexibility for rotable parts. Therefore, the applicability of 
this AD remains all The Boeing Company Model 787 series airplanes. The 
FAA has not changed this AD in this regard.

Request To Revise Summary and ``Actions Since AD 2017-15-04 Was 
Issued'' Section

    Boeing requested that the FAA revise the wording in the SUMMARY 
from ``. . . discrepant EMAs may have been installed on airplanes 
outside the original applicability . . .'' to ``. . . discrepant EMAs 
could be installed on airplanes outside the original applicability . . 
. .'' Boeing reasoned that the wording in the NPRM implies that the FAA 
has indication that discrepant EMAs have been installed in-service. 
Boeing infers that the intent of the phrase in the SUMMARY is a 
hypothetical statement that discrepant EMAs could be installed, and 
this intent was stated more clearly in the ``Actions Since AD 2017-15-
04 Was Issued'' section of the NPRM.
    The FAA partially agrees with the commenter's request. The FAA 
agrees that the proposed wording more closely matches the intent of the 
wording in the ``Actions Since AD 2017-15-04 Was Issued'' section of 
the NPRM. However, since neither that section of the SUMMARY nor the 
``Actions Since AD 2017-15-04 Was Issued'' section of the Discussion 
appear in the final rule, the FAA has not changed this final rule as 
requested. The FAA has, however, revised the statement of what prompted 
the AD in the Discussion section of this final rule to address the 
commenter's request.

Conclusion

    The FAA 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. The FAA has determined that these minor 
changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    The FAA 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

    The FAA reviewed Boeing Alert Service Bulletin B787-81205-SB270030-
00, Issue 002, dated April 7, 2017. The service information describes 
procedures for replacing affected EMAs with new EMAs.
    This AD also requires Boeing Service Bulletin B787-81205-SB270030-
00, Issue 001, dated October 22, 2015, which the Director of the 
Federal Register approved for incorporation by reference as of August 
25, 2017 (82 FR 33785, July 21, 2017).
    These documents are distinct since they apply to different 
airplanes. 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

    The FAA estimates that this AD would affect 93 airplanes of U.S. 
registry. The agency estimates the following costs to comply with 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.
    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

[[Page 6740]]

unsafe condition that is likely to exist or develop on products 
identified in this rulemaking action.

Regulatory Findings

    The FAA has 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) 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.

(h) New Definition

    For the purpose of this AD, an ``affected part'' is an EMA for 
spoiler 4, 5, 10, or 11 having part number (P/N) C99144-004 or 
C99144-005.

(i) New EMA Identification and Replacement

    For airplanes not identified in paragraph (g) of this AD with an 
original airworthiness certificate or an original export certificate 
of airworthiness dated before or on the effective date of this AD, 
do the actions specified in paragraphs (i)(1) and (2) of this AD.
    (1) Within 40 months after the effective date of this AD, 
perform a general visual inspection of the EMAs for spoilers 4, 5, 
10, and 11 to determine the part number. A review of airplane 
maintenance records is acceptable in lieu of this inspection if the 
part number of the EMA can be conclusively determined from that 
review.
    (2) If the EMA is an affected part: Within 40 months after the 
effective date of this AD, replace the EMA in accordance with the 
Accomplishment Instructions of Boeing Alert Service Bulletin B787-
81205-SB270030-00, Issue 002, dated April 7, 2017.

airplane an EMA having P/N C99144-004 or C99144-005.

(k) Credit for Previous Actions

    This paragraph provides credit for the action specified in 
paragraph (i)(2) of this AD, if that action was performed before the 
effective date of this AD using Boeing Service Bulletin B787-81205-
SB270030-00, Issue 001, dated October 22, 2015.

(l) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle 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 (m)(1) of this AD. Information may be 
emailed to: [email protected].
    (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.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by The Boeing Company Organization Designation 
Authorization (ODA) that has been authorized by the Manager, Seattle 
ACO Branch, FAA, to make those findings. To be approved, the repair 
method, modification deviation, or alteration deviation must meet 
the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) AMOCs approved previously for AD 2017-15-04 are approved as 
AMOCs for the corresponding provisions of paragraph (g) of this AD.
    (5) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(l)(5)(i) and (ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
