Airworthiness Directives; the Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 767-200, -300, -300F, and -400ER series 
airplanes. This AD was prompted by reports of cracked and corroded nuts 
on an outboard flap support rib. This AD requires, for certain 
airplanes, repetitive inspections of the cap seal for damaged sealant 
on nuts common to certain outboard flap support ribs, and related 
investigative and corrective actions if necessary. For certain other 
airplanes, this AD also requires repetitive inspections of the cap seal 
for damaged sealant on nuts common to certain outboard flap support 
ribs, related investigative and corrective actions if necessary, and if 
necessary, a detailed inspection to determine the nut type installed in 
the outboard flap support rib and corrective actions. This AD also 
provides terminating action for the repetitive inspections under 
certain conditions. We are issuing this AD to detect and correct 
cracked and corroded nuts and bolts and the installation of incorrect 
nuts on certain outboard flap support ribs, which could lead to 
additional nut and bolt damage in the joint, result in loss of an 
outboard flap, and adversely affect continued safe flight and landing 
of the airplane.

DATES: This AD is effective October 22, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of October 22, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM published in the Federal Register on April 10, 2013 (78 FR 
21276). The NPRM proposed to require, for certain airplanes, repetitive 
inspections of the cap seal for damaged sealant on nuts common to 
certain outboard flap support ribs, related investigative and 
corrective actions if necessary, and replacement of all fasteners in 
the support ribs, which terminates the repetitive inspections. For 
certain other airplanes, the NPRM proposed to require repetitive

[[Page 57050]]

inspections of the cap seal for damaged sealant on nuts common to 
certain outboard flap support ribs, related investigative and 
corrective actions if necessary, and if necessary, a detailed 
inspection to determine the nut type installed in the outboard flap 
support rib and corrective actions. For those airplanes, the NPRM also 
proposed to provide for optional replacement of all fasteners in the 
support ribs, which would terminate the repetitive inspections.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(78 FR 21276, April 10, 2013) and the FAA's response to each comment.

Request To Refer to Revised Service Information

    Japan Airlines, UPS, and Boeing stated that Boeing has issued 
revised service information and requested that the service information 
referenced in the NPRM (78 FR 21276, April 10, 2013) be updated to 
refer to Boeing Service Bulletin 767-57A0131, Revision 1, dated May 8, 
2013.
    We agree with the commenters' requests and have revised paragraphs 
(c), (g), (h), (i), and (j) of this final rule to include Boeing 
Service Bulletin 767-57A0131, Revision 1, dated May 8, 2013. We have 
also added a new paragraph (k) of this AD to provide credit for actions 
accomplished before the effective date of this AD using Boeing Alert 
Service Bulletin 767-57A0131, dated October 30, 2012, and reidentified 
the subsequent paragraphs.

Clarification Regarding the Installation of Winglets

    Aviation Partners Boeing and UPS stated that the installation of 
winglets per Supplemental Type Certificate (STC) ST01920SE (http://
rgl.faa.gov/Regulatory--and--Guidance--Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect 
the accomplishment of the manufacturer's service instructions.
    We agree with the commenters' statements that the installation of 
winglets as specified in STC ST01920SE (http://rgl.faa.gov/Regulatory--
and--Guidance--Library/rgstc.nsf/0/59027f43b9a7486e86257b1d006591ee/
$FILE/ST01920SE.pdf) does not affect accomplishment of the requirements 
of this AD, and for airplanes on which STC ST01920SE is installed, a 
``change in product'' AMOC approval request is not necessary to comply 
with the requirements of section 39.17 of the Federal Aviation 
Regulations (14 CFR 39.17). We have added this provision in new 
paragraph (c)(2) of this final rule.

Request To Correct a Reference to a Table Number

    UPS noted a typographical error in paragraph (h)(1)(i) of the NPRM 
(78 FR 21276, April 10, 2013). The inspection intervals are identified 
in table 2 of paragraph 1.E., ``Compliance,'' of Boeing Service 
Bulletin 767-57A0131, Revision 1, dated May 8, 2013, and the NPRM 
erroneously referred to table 1.
    We agree there is an error and have revised paragraph (h)(1)(i) of 
this AD to refer to table 2 of paragraph 1.E., ``Compliance,'' of 
Boeing Service Bulletin 767-57A0131, Revision 1, dated May 8, 2013.

Request To Clarify Terminating Action

    UPS noted that paragraph (i) of the NPRM (78 FR 21276, April 10, 
2013) implies that the only terminating action for the repetitive 
inspections proposed by paragraph (h) of the NPRM is replacement of all 
fasteners within a support rib. UPS stated that the Boeing service 
information provides terminating action by replacing fasteners at all 
discrepant or corroded locations and/or the verification of correct nut 
type at all other locations. UPS requested that these corrective 
actions be identified as terminating action for the inspections 
proposed by paragraph (h) of the NPRM for the associated support rib.
    We agree that clarification is needed regarding terminating action 
for the repetitive inspections required by paragraph (h) of this final 
rule. We have changed the header of paragraph (i) of this final rule to 
``Terminating Action for Repetitive Inspections'' and split the 
paragraph into three subparagraphs. Paragraph (i)(1) of this final rule 
states that, if during any inspection required by paragraphs (g) or (h) 
of this AD, any cracking is found, all fasteners within a support rib 
must be replaced to terminate the repetitive inspections for that 
support rib only. New paragraph (i)(2) of this final rule states that 
if a discrepancy other than cracking is found (e.g., corrosion) during 
any inspection required by paragraph (g) of this final rule, all 
fasteners within a support rib must be replaced to terminate the 
repetitive inspections for that support rib only. New paragraph (i)(3) 
of this final rule states that if a discrepancy other than cracking is 
found (e.g., corrosion) during any inspection required by paragraph (h) 
of this final rule, replacing the affected fastener terminates the 
repetitive inspections for only that fastener within that support rib.

Request To Combine Paragraphs (h)(1) and (h)(2) of the NPRM (78 FR 
21276, April 10, 2013)

    UPS stated that the intent of paragraph (h) of the NPRM (78 FR 
21276, April 10, 2013) is to identify the requirements of the initial 
inspection, and the intent of paragraphs (h)(1) and (h)(2) of the NPRM 
is to identify the requirements of the repetitive inspections based on 
the findings of the initial inspection. UPS stated that the 
investigative and corrective actions applicable to paragraph (h)(1) of 
the NPRM are the same as those in paragraph (h)(2) of the NPRM and 
suggested that these two paragraphs could be combined without affecting 
the intent of this AD.
    We do not agree that paragraphs (h)(1) and (h)(2) of this final 
rule can be combined. Paragraph (h)(1) of this final rule describes 
actions based on the findings of the cap seal detailed inspections, and 
paragraph (h)(2) of this final rule addresses actions based on the 
findings of the inspections for the nuts, bolts, and washers on the 
support ribs. We have not changed this final rule in this regard.

Request To Change Compliance Time for Initial Detailed Inspection

    UPS requested that the threshold for conducting the initial 
detailed inspection of the cap seal required by paragraphs (g) and (h) 
of the NPRM (78 FR 21276, April 10, 2013) be extended from 12 months to 
24 months. UPS commented that if it is not possible to extend the 
threshold for the initial inspection, then the text should be revised 
to read ``12 months after the AD effective date or within the 
appropriate total years of aircraft service-life''--whichever occurs 
later. UPS requested this change to reflect the reported technical data 
as well as to give operators time to schedule the task at a facility 
capable of accomplishing the scope of the work.
    We do not agree with UPS's request to extend the threshold for the 
initial detailed inspection. We have determined that the compliance 
time, as proposed, represents the maximum interval of time allowable 
for the affected airplanes to continue to safely operate before the 
initial inspection is done. Since maintenance schedules vary among 
operators, there would be no assurance that the airplane would be 
modified during that maximum interval. We have not changed this final 
rule in this regard.

[[Page 57051]]

    Furthermore, we do not agree with UPS's request to revise the 
compliance time text to include ``or within the appropriate total years 
of aircraft service-life''--whichever occurs later. The installation of 
an incorrect nut during production, and the possibility of the nut 
cracking due to being overtorqued, is unrelated to the age of the 
airplane. We have not changed this final rule in this regard.

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 (78 FR 21276, April 10, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 21276, April 10, 2013).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 440 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

have no way of determining the number of aircraft that might need these 
actions.

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

    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

    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, 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.

List of Subjects in 14 CFR Part 39

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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 adding the following new airworthiness 
directive (AD):

2013-18-02 The Boeing Company: Amendment 39-17575; Docket No. FAA-
2013-0301; Directorate Identifier 2013-NM-025-AD.

(a) Effective Date

    This AD is effective October 22, 2013.

(b) Affected ADs

    None.

(c) Applicability

    (1) This AD applies to The Boeing Company Model 767-200, 767-
300, 767-300F, and 767-400ER series airplanes; certificated in any 
category; as identified in Boeing Service Bulletin 767-57A0131,

[[Page 57052]]

$FILE/ST01920SE.pdf) does not affect the ability to accomplish the 
actions required by this AD. Therefore, for airplanes on which STC 
ST01920SE is installed, a ``change in product'' alternative method 
of compliance (AMOC) approval request is not necessary to comply 
with the requirements of 14 CFR 39.17.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 57, Wings.

(e) Unsafe Condition

an outboard flap support rib. We are issuing this AD to detect and 
correct cracked and corroded nuts and bolts and the installation of 
incorrect nuts on certain outboard flap support ribs, which could 
lead to additional nut and bolt damage in the joint, result in loss 
of an outboard flap, and adversely affect continued safe flight and 
landing of the airplane.
