Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER 
series airplanes. That AD currently requires inspecting for scribe 
lines in the skin along lap joints, butt joints, certain external 
doublers, and the large cargo door hinges, and doing related 
investigative and corrective actions if necessary. This new AD adds an 
inspection for scribe lines where external decals have been applied or 
removed across lap joints, large cargo door hinges, and external 
doublers, and related investigative and corrective actions if 
necessary. This AD was prompted by a determination that scribe lines 
could occur where external decals are installed or removed across lap 
joints, large cargo door hinges, or external doublers. We are issuing 
this AD to detect and correct scribe lines, which can develop into 
fatigue cracks in the skin. Undetected fatigue cracks can grow and 
cause sudden decompression of the airplane.

DATES: This AD is effective May 20, 2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2009-24-08, Amendment 39-16096 (74 FR 62217, 
November 27, 2009). That AD applies to the specified products. The NPRM 
published in the Federal Register on May 31, 2012 (77 FR 32057). That 
NPRM proposed to continue to require inspecting for scribe lines in the 
skin along lap joints, butt joints, certain external doublers, and the 
large cargo door hinges, and doing related investigative and corrective 
actions if necessary. Additionally, that NPRM proposed to add an 
inspection for scribe lines where external decals have been applied or 
removed across lap joints, large cargo door hinges, and external 
doublers, and related investigative and corrective actions if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 32057, May 31, 2012) and the FAA's response to each comment.

Requests To Change Compliance Time

    American Airlines (AAL), British Airways, Boeing, and Emirates 
Airlines requested that we change paragraph (l) of the NPRM (77 FR 
32057, May 31, 2012) to specify accomplishing the decal inspection at 
the compliance time described in Boeing Service Bulletin 777-53A0054, 
Revision 1, dated November 4, 2010, rather than the proposed ``within 
24 months after the effective date of this AD.'' The commenters stated 
that the initial compliance time in Boeing Service Bulletin 777-
53A0054, Revision 1, dated November 4, 2010, for the scribe line 
inspection is significantly later.
    We agree to change the compliance time for the reason the 
commenters stated. We have changed the compliance time in paragraph (l) 
of this AD to specify that the decal inspection must be done within 24 
months after the effective date of this AD, or at the applicable time 
specified in Boeing Service Bulletin 777-53A0054, Revision 1, dated 
November 4, 2010, for the scribe line inspection, whichever is later. 
We have also added a provision to paragraph (l) of this AD indicating 
that a review of airplane maintenance records is acceptable in lieu of 
the decal inspection if a record of all decal activities (installation 
or removal locations) can be conclusively determined from that review.

Request To Add Certain Exceptions

    AAL requested that we revise the NPRM (77 FR 32057, May 31, 2012) 
to state that the inspections described in Boeing Service Bulletin 777-
53A0054, Revision 1, dated November 4, 2010, are necessary only in 
``those areas that have been previously repaired and then the repair 
has been stripped and repainted.'' AAL asserted that the inspection 
exceptions described in NOTES 1. through 5. in paragraph 1.E., 
``Compliance,'' of Boeing Alert Service Bulletin 777-53A0054, dated 
August 7, 2008, apply to paragraph (g) of the NPRM, and that these 
notes state ``For each repair, if the operator can show that the 
airplane has never been stripped or repainted since the repair has been 
installed, then the repair inspections for that specific repair are not 
required.''
    We partially agree with the commenter's request. Note 1 to 
paragraph (g) of the NPRM (77 FR 32057, May 31, 2012) already allows 
such an exception, which is stated in NOTE 5 of paragraph 1.E., 
``Compliance,'' of Boeing Alert Service Bulletin 777-53A0054, dated 
August 7, 2008. We have changed paragraph (g) in the NPRM to paragraph 
(g)(1) in this AD and have also changed Note 1 to paragraph (g) of the 
NPRM to paragraph (g)(2) in this AD. Since we have revised paragraph 
(g)(1) of this AD to reference Revision 1 of Boeing Service Bulletin 
777-53A0054, dated November 4, 2010, as an appropriate source of 
service information, we have revised paragraph (g)(2) of this AD to 
state that the inspection exceptions described in NOTES 1. through 6. 
in paragraph 1.E., ``Compliance,'' of Boeing Service Bulletin 777-
53A0054, Revision 1, dated November 4, 2010, apply to paragraph (g)(1) 
of this AD.

Request To Exclude Service Bulletin Step

    AAL requested that we exclude the service information step of 
putting the airplane back in a serviceable condition, because that step 
does not affect the unsafe condition that the NPRM (77 FR 32057, May 
31, 2012) seeks to address. Additionally, AAL explained that most 
operators will accomplish these inspections as part of a heavy 
maintenance visit, and returning the airplane to a serviceable 
condition will not be possible in the context of that statement, but 
will rather occur at a point in time well after these inspections are 
complete.
    We agree with the request to state that the phrase ``Put the 
airplane back to serviceable condition,'' which is referenced in the 
service information specified in this final rule, is not mandated by 
this final rule. Other regulations require restoring the airplane to 
serviceable condition before further flight. Therefore, we have added 
exception phrasing in paragraphs (g)(1), (l), and (m) of this AD; and 
added new paragraph (n)(3) in this final rule.

Request To Use Alternative Measurement Tools

    AAL requested that we revise the NPRM (77 FR 32057, May 31, 2012) 
to include the use of alternative equivalent measurement tools, rather 
than the specialized tools described in Boeing Service Bulletin 777-
53A0054, Revision 1, dated November 4, 2010.
    We disagree with the commenter's request. To achieve an acceptable 
level

[[Page 22187]]

of safety for the inspections required by this AD, several specialized 
tools were employed. The commenter did not provide any alternative 
tool(s) for our consideration or any standard on how it might be 
determined that a tool might be equivalent to a tool specified in 
Boeing Service Bulletin 777-53A0054, Revision 1, dated November 4, 
2010. Under the provisions of paragraph (q) of this AD, however, we 
will consider requests for approval of an alternative method of 
compliance (AMOC) if sufficient data are submitted to substantiate that 
the proposed alternative measurement tool is equivalent to a 
measurement tool specified in Boeing Service Bulletin 777-53A0054, 
Revision 1, dated November 4, 2010. We have not changed this AD in this 
regard.

Request To Change Compliance Time Wording

    AAL requested that we change the compliance time wording in Boeing 
Service Bulletin 777-53A0054, Revision 1, dated November 4, 2010, from 
``after the original issue date `on' this service bulletin,'' to 
``after the original issue date `of' this service bulletin.''
    We disagree with the request to require Boeing to change the 
wording in Boeing Service Bulletin 777-53A0054, Revision 1, dated 
November 4, 2010. We do not consider delaying this AD action to address 
the identified unsafe condition necessary for this minor wording 
change. 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 
the 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 (77 FR 32057, May 31, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 32057, May 31, 2012).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Costs of Compliance

    We estimate that this AD affects 163 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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.

Regulatory Findings

    We have 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 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.

hinges, and external doublers, in accordance with the Accomplishment 
Instructions of Boeing Service Bulletin 777-53A0054, Revision 1, 
dated November 4, 2010, except as specified in paragraph (n)(3) of 
this AD. A review of airplane maintenance records is acceptable in 
lieu of this inspection if a record of all decal activities 
(installation or removal locations) can be conclusively determined 
from that review.

(m) New Inspection for Scribe Lines and Related Investigative and 
Corrective Actions

    If, during the inspection required by paragraph (l) of this AD, 
any location is found where external decals have been applied or 
removed across lap joints, large cargo door hinges, or external 
doublers: Before further flight, do a detailed exploratory 
inspection for scribe lines at all affected locations, in accordance 
with the Accomplishment Instructions of Boeing Service Bulletin 777-
53A0054, Revision 1, dated November 4, 2010, except as specified in 
paragraph (n)(3) of this AD. Do all applicable related investigative 
and corrective actions at the times specified in Boeing Service 
Bulletin 777-53A0054, Revision 1, dated November 4, 2010, by 
accomplishing all actions specified in the Accomplishment 
Instructions of Boeing Service Bulletin 777-53A0054, Revision 1, 
dated November 4, 2010, except as provided by paragraphs (i) and

(n) Exceptions to Service Information

    (1) Where Boeing Service Bulletin 777-53A0054, Revision 1, dated 
November 4, 2010, specifies a compliance time after the date on that 
service bulletin, paragraphs (l) and (m) of this AD require 
compliance within the specified compliance time after the effective 
date of this AD.
    (2) Where paragraph 1.E., ``Compliance,'' of Boeing Service 
Bulletin 777-53A0054, Revision 1, dated November 4, 2010, specifies 
to ``contact Boeing for inspection requirements for operation beyond 
60,000 total flight-cycles after first repaint,'' for those 
airplanes, this AD requires contacting the Manager, Seattle ACO, for 
all inspection requirements of this AD and for doing the 
requirements.
    (3) Where Boeing Service Bulletin 777-53A0054, Revision 1, dated 
November 4, 2010, specifies to ``Put the airplane back to a 
serviceable condition,'' this AD does not require that action.

 (o) Credit for Previous Actions

    This paragraph provides credit for the actions required by 
paragraph (m) of this AD, if those actions were performed before the 
effective date of this AD using Boeing Alert Service Bulletin 777-
53A0054, dated August 7, 2008.

(p) Paperwork Reduction Act Burden Statement

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty 
for failure to comply with a collection of information subject to 
the requirements of the Paperwork Reduction Act unless that 
collection of information displays a current valid OMB Control 
Number. The OMB Control Number for this information collection is 
2120-0056. Public reporting for this collection of information is 
estimated to be approximately 5 minutes per response, including the 
time for reviewing instructions, completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Comments concerning the accuracy of this 
burden and suggestions for reducing the

[[Page 22189]]

burden should be directed to the FAA at: 800 Independence Ave. SW., 
Washington, DC 20591, Attn: Information Collection Clearance 
Officer, AES-200.

(q) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO, 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 
ACO, send it to the attention of the person identified in the 
Related Information section 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 required by this AD if it is approved by the 
Boeing Commercial Airplanes Organization Designation Authorization 
(ODA) that has been authorized by the Manager, Seattle ACO, to make 
those findings. For a repair method to be approved, the repair must 
meet the certification basis of the airplane, and the approval must 
specifically refer to this AD.
    (4) AMOCs approved for AD 2009-24-08, Amendment 39-16096 (74 FR 
62217, November 27, 2009), are approved as AMOCs for the 
corresponding provisions of this AD, except that AMOCs approved for 
AD 2009-24-08 are not approved for fuselage areas where any decals 
may have been installed or removed on airplanes that have never been 
stripped or repainted since they left the factory.
