Federal Register Abstract
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767 airplanes. This AD was prompted by reports that six fasteners may not have been installed in the left and right stringer 37 (S-37) between body stations (BS) 428 and 431 lap splices on certain airplanes. This AD requires a general visual inspection of S-37 lap splices for missing fasteners, and all applicable related investigative and corrective actions. We are issuing this AD to detect and correct missing fasteners, which could result in cracks in the fuselage skin that could adversely affect the structural integrity of the airplane.

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 767 airplanes. The NPRM published in the Federal Register on
December 29, 2014 (79 FR 77970). The NPRM was prompted by reports that
six fasteners may not have been installed in the left and right S-37
between BS 428 and 431 lap splices on certain airplanes. The NPRM
proposed to require a general visual inspection of S-37 lap splices for
missing fasteners, and all applicable related investigative and
corrective actions. We are issuing this AD to detect and correct
missing fasteners, which could result in cracks in the fuselage skin
that could adversely affect the structural integrity of the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM (79
FR 77970, December 29, 2014) and the FAA's response to each comment.
Support for the NPRM (79 FR 77970, December 29, 2014)
Boeing and Debra Abdou supported the NPRM (79 FR 77970, December
29, 2014). FedEx Express explained that the NPRM will not impact them.
United Airlines stated that it has no comment on the NPRM.
Request for Credit for Previous Actions
United Parcel Service (UPS) requested that we revise the NPRM (79
FR 77970, December 29, 2014), to clarify that no further actions are
required for airplanes that have previously accomplished inspections
and corrective actions as specified in Boeing Message TBC-UPS-13-0004-
01B (Service Request 1-2412169241), dated February 1, 2013.
UPS explained that, prior to the release of Boeing Alert Service
Bulletin 767-53A0251, dated August 7, 2013, Boeing had released Boeing
Fleet Team Digest article 767-FTD-53-12003, dated September 21, 2012;
and Boeing Message TBC-UPS-13-0004-01B (Service Request 1-2412169241),
dated February 1, 2013; to address the discrepant condition and provide
applicable corrective actions. UPS stated that it has previously
accomplished inspections and corrective actions on all affected UPS
Model 767-300F series airplanes in accordance with Boeing Fleet Team
Digest article 767-FTD-53-12003 dated September 21, 2012, and Boeing
Message TBC-UPS-13-0004-01B (Service Request 1-2412169241), dated
February 1, 2013. Per Boeing Message TBC-UPS-13-0004-01B (Service
Request 1-2412169241), dated February 1, 2013, the following corrective
actions are to be accomplished prior to further flight if the affected
fasteners are found missing:
<bullet> Remove the center row and adjacent fasteners around the
missing fastener locations.
<bullet> Perform open-hole high frequency eddy current (HFEC)
inspection for damages.
<bullet> If no damage is found, install BACR15FV6KE* rivets per the
Boeing installation drawing.
<bullet> If damage is found, repair per the service repair manual
section defined in the future service bulletin.
UPS reasoned that, as indicated in Boeing Message TBC-UPS-13-0004-
01B (Service Request 1-2412169241), dated February 1, 2013, the
additional detailed inspection shown in Figure 2, Step 1, of Boeing
Alert Service Bulletin 767-53A0251, dated August 7, 2013, is not
required to detect damages resulting from the discrepant condition. UPS
expressed that, as supported by Boeing Message TBC-UPS-13-0004-01B
(Service Request 1-2412169241), dated February 1, 2013, the open-hole
HFEC inspection is sufficient for detecting and eliminating damage
resulting from the identified unsafe condition. UPS pointed out that
standard maintenance procedures ensure that the external and internal
areas accessed and disturbed during accomplishment of the repair are
restored to normal configuration. Furthermore, UPS explained that
supplemental internal and external inspections of the affected area are
accomplished per UPS maintenance program as specified in Boeing
Maintenance Planning Document Items 53-460-00, 53-648-00, 53-800-00,
and 53-820-00.
We disagree to provide credit for certain actions required by this
AD if those actions were performed before the effective date of this AD
using Boeing Message TBC-UPS-13-0004-01B (Service Request 1-2412169241)
dated February 1, 2013. It is possible that individual instructions
provided to the specific operator via Boeing Message TBC-UPS-13-0004-
01B (Service Request 1-2412169241), dated February 1, 2013, may have
different instructions than those specified in the Accomplishment
Instructions of Boeing Alert Service Bulletin 767-53A0251, dated August
7, 2013. However, under the provisions of paragraph (i) of this AD, we
will consider requests for approval of credit for certain actions if
sufficient data are submitted to substantiate that the change would
provide an acceptable level of safety. We have made no changes to this
AD in this regard.
Effect of Winglets on AD
Aviation Partners Boeing stated that accomplishing the supplemental
type certificate (STC) ST01920SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect
the actions specified in the NPRM (79 FR 77970, December 29, 2014). We
concur with the commenter. We have redesignated paragraph (c) of the
proposed AD as paragraph (c)(1) and added new paragraph (c)(2) to this
AD to state that installation of STC ST01920SE does not affect the
ability to accomplish the actions required by this final rule.
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.
Related Service Information Under 1 CFR Part 51
Boeing has issued Boeing Alert Service Bulletin 767-53A0251, dated
August 7, 2013. The service information describes procedures for an
external general visual inspection of the S-37 lap splice for missing
fasteners, detailed and open-hole inspections of the skin for any
crack, corrosion, or other discrepancy; determining if the crack,
corrosion, or other discrepancy is within the repair limits, and
repairing. This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means
[[Page 58348]]
identified in the ADDRESSES section of this AD.
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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (79 FR 77970, December 29, 2014) for correcting the unsafe
condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 77970, December 29, 2014).
Costs of Compliance
We estimate that this AD affects 23 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
General visual inspection........... 1 work-hour x $85 per $0 $85 $1,955
hour = $85.
----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary inspections/
installations that would be required based on the results of the
required inspection. We have no way of determining the number of
aircraft that might need these inspections/installations:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Detailed and HFEC inspections and fastener 13 work-hours x $85 per hour = * $1,105
installation. $1,105.
----------------------------------------------------------------------------------------------------------------
* All parts that are required are supplied by the operator. This cost is minimal, and we have no way to
determine what the operators would pay for these parts.
We have received no definitive data that would enable us to provide
cost estimates for the repairs specified in this AD.
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 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.

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):
2015-19-12 The Boeing Company: Amendment 39-18274; Docket No. FAA-
2014-0929; Directorate Identifier 2014-NM-118-AD.
(a) Effective Date
This AD is effective November 3, 2015.
(b) Affected ADs
None.
(c) Applicability
(1) This AD applies to The Boeing Company Model 767-200, -300, -
300F, and -400ER series airplanes, certificated in any category, as
identified in Boeing Alert Service Bulletin 767-53A0251, dated
August 7, 2013.
(2) Installation of Supplemental Type Certificate (STC)
[ST01920SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/59027f43b9a7486e86257b1d00659v1ee/$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
[[Page 58349]]
request is not necessary to comply with the requirements of 14 CFR
39.17.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by reports that six fasteners may not have
been installed in the left and right stringer 37 (S-37) between body
stations (BS) 428 and 431 lap splices on certain airplanes. We are
issuing this AD to detect and correct missing fasteners, which could
result in cracks in the fuselage skin that could adversely affect
the structural integrity of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspections, Related Investigative Actions, and Corrective Actions
Except as provided by paragraph (h)(2) of this AD, at the
applicable time specified in paragraph 1.E., ``Compliance,'' of
Boeing Alert Service Bulletin 767-53A0251, dated August 7, 2013: Do
an external general visual inspection of the S-37 lap splice for
missing fasteners, and do all applicable related investigative and
corrective actions, in accordance with the Accomplishment
Instructions of Boeing Alert Service Bulletin 767-53A0251, dated
August 7, 2013, except as provided by paragraph (h)(1) of this AD.
Do all applicable related investigative and corrective actions
before further flight.
(h) Exceptions to Service Information Specifications
(1) Although Boeing Alert Service Bulletin 767-53A0251, dated
August 7, 2013, specifies to contact Boeing for repair instructions,
and specifies that action as ``RC'' (Required for Compliance), this
AD requires repair before further flight using a method approved in
accordance with the procedures specified in paragraph (i)(1) of this
AD.
(2) Where Paragraph 1.E., ``Compliance,'' of Boeing Alert
Service Bulletin 767-53A0251, dated August 7, 2013, specifies a
compliance time ``after the original issue date of this service
bulletin,'' this AD requires compliance within the specified
compliance time after the effective date of this AD.
(i) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Seattle Aircraft Certification Office (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 paragraph (j) of this AD.

(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) Except as required by paragraph (h)(1) of this AD: For
service information that contains steps that are labeled as Required
for Compliance (RC), the provisions of paragraphs (i)(4)(i) and
(i)(4)(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. 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
