We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 767-200 and -300 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the aft pressure bulkhead web to pressure chord joint is subject to widespread fatigue damage (WFD). This proposed AD would require repetitive high frequency eddy current (HFEC) inspections of the aft pressure bulkhead web, at fasteners common to the bulkhead web and pressure chord, around the entire circumference of the pressure chord for any crack, and repair of cracks. We are proposing this AD to detect and correct cracks in the aft pressure bulkhead web. Such cracking could result in the loss of structural integrity of the airplane.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
The Boeing Company Model 767-200 and -300 series airplanes. This 
proposed AD was prompted by an evaluation by the design approval holder 
(DAH) indicating that the aft pressure bulkhead web to pressure chord 
joint is subject to widespread fatigue damage (WFD). This proposed AD 
would require repetitive high frequency eddy current (HFEC) inspections 
of the aft pressure bulkhead web, at fasteners common to the bulkhead 
web and pressure chord, around the entire circumference of the pressure 
chord for any crack, and repair of cracks. We are proposing this AD to 
detect and correct cracks in the aft pressure bulkhead web. Such 
cracking could result in the loss of structural integrity of the 
airplane.

Discussion

    Structural fatigue damage is progressive. It begins as minute 
cracks, and those cracks grow under the action of repeated stresses. 
This can happen because of normal operational conditions and design 
attributes, or because of isolated situations or incidents such as 
material defects, poor fabrication quality, or corrosion pits, dings, 
or scratches. Fatigue damage can occur locally, in small areas or 
structural design details, or globally. Global fatigue damage is 
general degradation of large areas of structure with similar structural 
details and stress levels. Multiple-site damage is global damage that 
occurs in a large structural element such as a single rivet line of a 
lap splice joining two large skin panels. Global damage can also occur 
in multiple elements such as adjacent frames or stringers. Multiple-
site-damage and multiple-element-damage cracks are typically too small 
initially to be reliably detected with normal inspection methods. 
Without intervention, these cracks will grow, and eventually compromise 
the structural integrity of the airplane, in a condition known as WFD. 
As an airplane ages, WFD will likely occur, and will certainly occur if 
the airplane is operated long enough without any intervention.
    The FAA's WFD final rule (75 FR 69746, November 15, 2010) became 
effective on January 14, 2011. The WFD rule requires certain actions to 
prevent structural failure due to WFD throughout the operational life 
of certain existing transport category airplanes and all of these 
airplanes that will be certificated in the future. For existing and 
future airplanes subject to the WFD rule, the rule requires that DAHs 
establish a limit of validity (LOV) of the engineering data that 
support the structural maintenance program. Operators affected by the 
WFD rule may not fly an airplane beyond its LOV, unless an extended LOV 
is approved.
    The WFD rule (75 FR 69746, November 15, 2010) does not require 
identifying and developing maintenance actions if the DAHs can show 
that such actions are not necessary to prevent WFD before the airplane 
reaches the LOV. Many LOVs, however, do depend on accomplishment of 
future maintenance actions. As stated in the WFD rule, any maintenance 
actions necessary to reach the LOV will be mandated by airworthiness 
directives through separate rulemaking actions.
    In the context of WFD, this action is necessary to enable DAHs to 
propose LOVs that allow operators the longest operational lives for 
their airplanes, and still ensure that WFD will not occur. This 
approach allows for an implementation strategy that provides 
flexibility to DAHs in determining the timing of service information 
development (with FAA approval), while providing operators with 
certainty regarding the LOV applicable to their airplanes.
    The FAA has received a report indicating that an evaluation by the 
DAH has indicated that the aft pressure bulkhead web to pressure chord 
joint is subject to WFD. This condition, if not corrected could result 
in cracks from the aft pressure bulkhead web to pressure chord joint 
and possible loss of structural integrity of the airplane.

Related Service Information Under 1 CFR part 51

    We reviewed Boeing Alert Service Bulletin 767-53A0268, dated April 
1, 2015. This service information describes procedures for repetitive 
high frequency eddy current (HFEC) inspections of all visible locations 
of the aft pressure bulkhead web, at fasteners common to the bulkhead 
web and pressure chord, and around the entire circumference of the 
pressure chord for any crack, and repair of cracks. 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.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.'' For information on the procedures and compliance times, 
see this service information at http://www.regulations.gov by searching 
for and locating Docket No. FAA-2016-4221.

Differences between This Proposed AD and the Service Information

    Boeing Alert Service Bulletin 767-53A0268, dated April 1, 2015, 
specifies to contact the manufacturer for instructions on how to repair 
certain conditions, but this proposed AD would require repairing those 
conditions in one of the following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) whom we have 
authorized to make those findings.
    The applicability in this proposed AD is not limited to airplanes 
identified in Boeing Alert Service Bulletin 767-53A0268, dated April 1, 
2015. That service information does not contain a comprehensive list of 
the airplanes that are subject to the identified unsafe condition. This 
proposed AD would therefore apply to all Model 767-200 and -300 series 
airplanes.

Costs of Compliance

    We estimate that this proposed AD affects 296 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

[[Page 12049]]



                                                                     Estimated Costs
--------------------------------------------------------------------------------------------------------------------------------------------------------
                                                                                     Cost per
                Action                        Labor cost           Parts cost        product                      Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection...........................  57 work-hours x $85 per              $0           $4,845   $1,434,120 per inspection cycle.
                                        hour = $4,845 per
                                        inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    The size of any repair area needs to be determined before material 
and work-hour costs can be calculated. We have received no definitive 
data that would enable us to provide cost estimates for the on-
condition actions specified in this proposed 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 determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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):

The Boeing Company: Docket No. FAA-2016-4221; Directorate Identifier 
2015-NM-167-AD.

(a) Comments Due Date

    We must receive comments by April 22, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 767-200 and -300 
series airplanes, certificated in any category.

(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 aft pressure bulkhead web to 
pressure chord joint is subject to widespread fatigue damage (WFD). 
We are issuing this AD to detect and correct cracks in the aft 
pressure bulkhead web to pressure chord joint which could result in 
the loss of structural integrity of the airplane.

(f) Compliance

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

(g) Repetitive Inspections

    Except as required by paragraph (h) of this AD, at the 
applicable time specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin 767-53A0268, dated April 1, 2015, 
perform a surface high frequency eddy current (HFEC) inspection for 
cracking of the aft pressure bulkhead web, at fasteners common to 
the bulkhead web and pressure chord, around the entire circumference 
of the pressure chord, in accordance with the Accomplishment 
Instructions of Boeing Alert Service Bulletin 767-53A0268, dated 
April 1, 2015. For this AD, Group 2, Configuration 2, as specified 
in Boeing Alert Service Bulletin 767-53A0268, dated April 1, 2015, 
includes airplanes with the aft pressure bulkhead replaced as 
specified in Boeing Alert Service Bulletin 767-53A0267. Repeat the 
inspection thereafter at the applicable time specified in paragraph 
1.E., ``Compliance,'' of Boeing Alert Service Bulletin 767-53A0268, 
dated April 1, 2015.

(h) Service Information Exception

    Where Boeing Alert Service Bulletin 767-53A0268, dated April 1, 
2015, 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) Crack Repair

    If any crack is found during any inspection required by 
paragraph (g) of this AD, before further flight, repair the crack 
using a method approved in accordance with the procedures specified 
in paragraph (j) of this AD. Although Boeing Alert Service Bulletin 
767-53A0268, dated April 1, 2015, specifies to contact Boeing for 
repair instructions, and specifies that action as ``RC'' (Required 
for Compliance), this AD requires repair as specified in this 
paragraph. Installation of a repair terminates the inspections 
required by paragraph (g) of this AD in the area covered by the 
repair only.

(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: [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

[[Page 12050]]

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) Except as required by paragraph (i) of this AD: For service 
information that contains steps that are labeled as RC, the 
provisions of paragraphs (j)(4)(i) and (j)(4)(ii) 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 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
