We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-200 and -300 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the frame-to-floor-beam joints and frames common to shear ties at certain locations of fuselage structure are subject to widespread fatigue damage (WFD). This AD requires inspections for cracking of certain frame inner chords and webs common to the floor beam joint and at frames common to the shear ties at certain sections, and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.

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 all The
Boeing Company Model 767-200 and -300 series airplanes. This AD was
prompted by an evaluation by the design approval holder (DAH)
indicating that the frame-to-floor-beam joints and frames common to
shear ties at certain locations of fuselage structure are subject to
widespread fatigue damage (WFD). This AD requires inspections for
cracking of certain frame inner chords and webs common to the floor
beam joint and at frames common to the shear ties at certain sections,
and corrective action if necessary. We are issuing this AD to address
the unsafe condition on these products.

DATES: This AD is effective April 7, 2017.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 7,
2017.

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 all The Boeing Company
Model 767-200 and -300 series airplanes. The NPRM published in the
Federal Register on July 7, 2016 (81 FR 44246). The NPRM was prompted
by an evaluation by the DAH indicating that the frame-to-floor-beam
joints and frames common to shear ties at certain locations of fuselage
structure are subject to WFD. The NPRM proposed to require repetitive
inspections for cracking of the frame inner chords and webs common to
the floor beam joint and at frames common to the shear ties at certain
sections on the left and right fuselage sides, and corrective action if
necessary. We are issuing this AD to detect and correct cracking of the
frame inner chords and webs common to the floor beam joint and at
frames common to the shear ties at certain sections on the left and
right fuselage sides, which could result in reduced 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 and
the FAA's response to each comment.

Support for the NPRM

Boeing and United Airlines expressed support for the NPRM.

Effect of Winglets on Accomplishment of the Proposed Actions

Aviation Partners Boeing stated that accomplishing the Supplemental
Type Certificate (STC) ST01920SE does not affect the ability to
accomplish the actions specified in the NPRM.
We concur with the commenter. We have redesignated paragraph (c) of
the proposed AD as (c)(1) and added 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.

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:

[[Page 12411]]

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 Boeing Alert Service Bulletin 767-53A0265, Revision 1,
dated March 18, 2016. The service information describes procedures for
doing a detailed inspection and a surface high frequency eddy current
(HFEC) inspection for cracking of the frame inner chord and web common
to the floor beam joint in sections 41 and 43 on the left and right
sides, a detailed inspection and a surface HFEC inspection for cracking
of the section 43 and 46 frames common to the shear ties on the left
and right sides, and repair. 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 306 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspections............... Up to 350 work-hours x $0 Up to $29,750 per Up to $9,103,500 per
$85 per hour = $29,750 inspection cycle. inspection cycle.
per inspection cycle.
----------------------------------------------------------------------------------------------------------------

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

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.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

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):

2017-05-06 The Boeing Company: Amendment 39-18816; Docket No. FAA-
2016-7423; Directorate Identifier 2016-NM-034-AD.

(a) Effective Date

This AD is effective April 7, 2017.

(b) Affected ADs

None.

(1) This AD applies to all The Boeing Company Model 767-200 and
-300 series airplanes, certificated in any category.
(2) Installation of Supplemental Type Certificate (STC)
ST01920SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/59027f43b9a7486e86257b1d006591ee/$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

Air Transport Association (ATA) of America Code 53; Fuselage.

(e) Unsafe Condition

This AD was prompted by an evaluation by the design approval
holder (DAH) indicating that the frame-to-floor-beam joints and
frames common to shear ties at certain locations of fuselage
structure are subject to widespread fatigue damage (WFD). We are
issuing this AD to detect and correct cracking of the frame inner
chords and webs common to the floor beam joint and at frames common
to the shear ties at certain sections on the left and right fuselage
sides, which could result in reduced structural integrity of the
airplane.

(f) Compliance

Comply with this AD within the compliance times specified,
unless already done.

(g) Inspections and Corrective Actions

Except as provided by paragraph (h) of this AD, at the
applicable time specified in paragraph 1.E., ``Compliance,'' of
Boeing Alert Service Bulletin 767-53A0265, Revision 1, dated March
18, 2016 (``ASB 767-53A0265, R1''): Do the actions required in
paragraphs (g)(1) and (g)(2) of this AD, and

[[Page 12412]]

do all applicable corrective actions, in accordance with the
Accomplishment Instructions of ASB 767-53A0265, R1. Do all
applicable corrective actions before further flight. Repeat the
inspections specified in paragraphs (g)(1) and (g)(2) of this AD
thereafter at the applicable intervals specified in paragraph 1.E.,
``Compliance,'' of ASB 767-53A0265, R1.
(1) Do a detailed inspection and a surface high frequency eddy
current (HFEC) inspection for cracking of the frame inner chord and
web common to the floor beam joint in sections 41 and 43 on the left
and right sides.
(2) Do a detailed inspection and a surface HFEC inspection for
cracking of the section 43 and 46 frames common to the shear ties on
the left and right sides.

(h) Service Information Exception

Where ASB 767-53A0265, R1 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) Credit for Previous Actions

This paragraph provides credit for the actions specified in
paragraph (g) of this AD, if those actions were performed before the
effective date of this AD using Boeing Alert Service Bulletin 767-
53A0265, dated March 18, 2015.

(j) 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 (k)(1) of this AD.
Information may be emailed to: 9-ANM-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 Commercial Airplanes Organization
Designation Authorization (ODA) that has been authorized by the
Manager, Seattle ACO, 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) For service information that contains steps that are labeled
as Required for Compliance (RC), the provisions of paragraphs
(j)(4)(i) and (j)(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. 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.
