Federal Register Volume 83, Issue 51 (March 15, 2018)

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the side panel-to-frame attachments and frames of the aft cargo compartment are subject to widespread fatigue damage (WFD). This AD requires an inspection of the side panel-to-frame attachments and frames to verify that certain modifications have been done, and applicable on-condition actions. 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 certain 
The Boeing Company Model 757-200 series airplanes. This AD was prompted 
by an evaluation by the design approval holder (DAH) indicating that 
the side panel-to-frame attachments and frames of the aft cargo 
compartment are subject to widespread fatigue damage (WFD). This AD 
requires an inspection of the side panel-to-frame attachments and 
frames to verify that certain modifications have been done, and 
applicable on-condition actions. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective April 19, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 19, 
2018.

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 757-200 series airplanes. The NPRM published in the Federal 
Register on August 25, 2017 (82 FR 40508). The NPRM was prompted by an 
evaluation by the DAH indicating that the side panel-to-frame 
attachments and frames of the aft cargo compartment are subject to WFD. 
The NPRM proposed to require an inspection of the side panel-to-frame 
attachments and frames to verify that certain modifications have been 
done, and applicable on-condition actions. We are issuing this AD to 
prevent fatigue cracking at the attachment points of the side panel-to-
frame attachments of the aft cargo compartment, which could result in 
reduced structural integrity of the body frames, and consequent rapid 
decompression of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. 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 agreed with the content of the NPRM.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that accomplishing the supplemental 
type certificate (STC) ST01518SE does not affect the actions specified 
in the NPRM.
    We concur with the commenter. We have redesignated paragraph (c) of 
the proposed AD as paragraph (c)(1) of this AD and added paragraph 
(c)(2) to this AD to state that installation of STC ST01518SE does not 
affect the ability to accomplish the actions required by this AD. 
Therefore, for airplanes on which STC ST01518SE 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.

Request To Provide Instructions for Previously Repaired Areas

    FedEx Express asked that instructions to address previously 
repaired areas on which the modification has not been incorporated be 
added to Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated 
January 25, 2017, before issuing the proposed AD.
    We do not agree with the commenter's request. To wait for Boeing to 
update the service bulletin, as requested, would delay the issuance of 
the final rule. However, to delay this action would be inappropriate 
since we have determined that an unsafe condition exists and that the 
actions required by this AD must be done to ensure continued safety. If 
a previously repaired area does not incorporate the modification 
required by this AD, and the modification cannot be done on the 
previously repaired area, operators must request an alternative method 
of compliance (AMOC) using the procedures specified in paragraph (j) of 
this AD. We have made no change to 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 
this final rule 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 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 final 
rule.

    Related Service Information Under 1 CFR Part 51
    We reviewed Boeing Alert Service Bulletin 757-53A0012, Revision 1, 
dated January 25, 2017. The service information describes procedures 
for a general visual inspection of the side panel-to-frame attachments 
and frames to verify that certain modifications have been done. The 
service information also describes procedures for on-condition actions, 
which include repetitive inspections for cracking, repairs, and 
modifications. 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 13 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 hour               $0             $85          $1,105
                                      = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
actions that are required. We have no way of determining the number of 
aircraft that might need these on-condition actions.

                Estimated Costs of On-Condition Actions *
------------------------------------------------------------------------
           Labor cost                 Parts cost       Cost per product
------------------------------------------------------------------------
Up to 45 work-hours x $85 per     Unavailable.......  Up to $3,825.
 hour = Up to $3,825.
------------------------------------------------------------------------
* The costs in the table do not include the cost estimate for on-
  condition repairs. We have received no definitive data that would
  enable us to provide cost estimates for the on-condition repairs
  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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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):

2018-06-08 The Boeing Company: Amendment 39-19228; Docket No. FAA-
2017-0778; Product Identifier 2017-NM-038-AD.

(a) Effective Date

    This AD is effective April 19, 2018.

(b) Affected ADs

    None.

(c) Applicability

    (1) This AD applies to The Boeing Company Model 757-200 series 
airplanes, certificated in any category, as identified in Boeing 
Alert Service Bulletin 757-53A0012, Revision 1, dated January 25, 
2017.
    (2) Installation of Supplemental Type Certificate (STC) 
ST01518SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/312bc296830a925c86257c85006d1b1f/$FILE/ST01518SE.pdf) 
does not affect the ability to accomplish the actions required by 
this AD. Therefore, for airplanes on which STC ST01518SE 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.

[[Page 11399]]

(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 indicating that the side panel-to-frame attachments and 
frames of the aft cargo compartment are subject to widespread 
fatigue damage. We are issuing this AD to prevent fatigue cracking 
at the attachment points of the side panel-to-frame attachments of 
the aft cargo compartment, which could result in reduced structural 
integrity of the body frames, and consequent rapid decompression of 
the airplane.

(f) Compliance

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

(g) One-Time General Visual Inspection and Corrective Actions

    Except as required by paragraph (h) of this AD: At the 
applicable times specified in paragraph 1.E., ``Compliance,'' of 
Boeing Alert Service Bulletin 757-53A0012, Revision 1, dated January 
25, 2017, do all applicable actions identified as ``RC'' (required 
for compliance) in, and in accordance with, the Accomplishment 
Instructions of Boeing Alert Service Bulletin 757-53A0012, Revision 
1, dated January 25, 2017.

(h) Exceptions to Service Information Specifications

    (1) For purposes of determining compliance with the requirements 
of this AD: Where Boeing Alert Service Bulletin 757-53A0012, 
Revision 1, dated January 25, 2017, uses the phrase ``the Revision 1 
date of this service bulletin,'' this AD requires using ``the 
effective date of this AD.''
    (2) Where Boeing Alert Service Bulletin 757-53A0012, Revision 1, 
dated January 25, 2017, specifies contacting Boeing, and specifies 
that action as RC: This AD requires repair using a method approved 
in accordance with the procedures specified in paragraph (j) of this 
AD.

(i) Terminating Action for Inspections

    Accomplishment of a modification in accordance with the 
Accomplishment Instructions of Boeing Alert Service Bulletin 757-
53A0012, Revision 1, dated January 25, 2017, terminates the 
inspections required by paragraph (g) of this AD at the modified 
location only.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles ACO Branch, 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 certification office, send it to the attention of 
the person identified in paragraph (k) 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 Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Los Angeles ACO Branch, 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 (h)(2) 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) 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.
