Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2011-01-15, 
which applied to certain The Boeing Company Model 757-200, -200CB, and 
-300 series airplanes. AD 2011-01-15 required repetitive inspections 
for cracking of the fuselage skin of the crown skin panel along the 
chem-milled step at certain stringers, and repair if necessary. This AD 
adds repetitive inspections for cracking in additional areas, and 
repair if necessary; removes airplanes from the applicability; adds an 
optional skin panel replacement, which terminates all inspections; adds 
an optional preventive modification, which terminates certain 
inspections; and reduces the compliance time for certain inspections. 
This AD was prompted by reports of the initiation of new fatigue 
cracking in the fuselage skin of the crown skin panel along locally 
thinned channels adjacent to the chem-milled steps. We are issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective November 6, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 6, 
2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2011-01-15, Amendment 39-16572 (76 FR 1351, 
January 10, 2011) (``AD 2011-01-15''). AD 2011-01-15 applied to certain 
The Boeing Company Model 757-200, -200CB, and -300 series airplanes. AD 
2011-01-15 required repetitive inspections for cracking of the fuselage 
skin of the crown skin panel along the chem-milled step at stringers S-
4L and S-4R, from station (STA) 297 through STA 439, and repair if 
necessary. AD 2011-01-15 also included terminating action for the 
repetitive inspections of the repaired areas only. AD 2011-01-15 
resulted from reports of cracking in the fuselage skin of the crown 
skin panel. The NPRM published in the Federal Register on February 18, 
2016 (81 FR 8157) (``The NPRM''). The NPRM was prompted by reports of 
the initiation of new fatigue cracking in the fuselage skin of the 
crown skin panel along locally thinned channels adjacent to the chem-
milled steps. The NPRM proposed to add repetitive inspections for 
cracking in additional areas, and repair if necessary. The NPRM also 
proposed to remove airplanes from the applicability in AD 2011-01-15. 
The NPRM also proposed to add an optional skin panel replacement, which 
would terminate all inspections, and an optional preventive 
modification, which would terminate certain inspections.
    We issued a supplemental NPRM (SNPRM) that published in the Federal 
Register on May 5, 2017 (82 FR 21146). The SNPRM proposed to reduce the 
compliance time for certain inspections.
    We are issuing this AD to correct the unsafe condition on these 
products.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the SNPRM and 
the FAA's response to each comment.

Supportive Comment

    United Airlines and Boeing concurred with the SNPRM.

Request for Alternative Method of Compliance (AMOC)

    VT Mobile Aerospace Engineering (MAE) Inc. stated that the proposed 
AD (in the SNPRM) affects Model 757-200 airplanes that were modified 
using certain VT MAE supplemental type certificates (STCs). VT MAE 
noted that its design at certain inspection locations is not identical 
to that of the Boeing STC design at those locations. Therefore, VT MAE 
plans to issue new service information to address the unsafe condition, 
and plans to request approval of an AMOC from the FAA for use of the 
new service information.
    FedEx stated that its airplanes have been modified in accordance 
with the VT MAE STC, and once this AMOC is approved to address this 
issue, FedEx will use it to comply with the requirements in the 
proposed AD (in the SNPRM).
    We acknowledge the commenters' remarks. Under the provisions of 
paragraph (n) of this AD, we will consider requests for approval of an 
AMOC that addresses the VT MAE STCs, if appropriate data are submitted 
to substantiate that the method would provide an acceptable level of 
safety. 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 AD as proposed, except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 757-53-0097, 
Revision 3, dated December 2, 2016. This service information describes 
procedures for repetitive external sliding probe eddy current (EC) and 
external spot-probe-medium-frequency EC inspections for cracking of the 
crown skin panel, repair, a preventive modification, and replacement of 
the crown skin panel. 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 652 airplanes of U.S. registry.
    We estimate the following costs to comply with 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

[[Page 45699]]

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

    We have determined that 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 removing Airworthiness Directive (AD) 
2011-01-15, Amendment 39-16572 (76 FR 1351, January 10, 2011), and 
adding the following new AD:

2017-20-05 The Boeing Company: Amendment 39-19062; Docket No. FAA-
2016-3697; Product Identifier 2015-NM-143-AD.

(a) Effective Date

    This AD is effective November 6, 2017.

(b) Affected ADs

    This AD replaces AD 2011-01-15, Amendment 39-16572 (76 FR 1351, 
January 10, 2011) (``AD 2011-01-15'').

(c) Applicability

    (1) This AD applies to The Boeing Company Model 757-200 and -300 
series airplanes, certificated in any category, as identified in 
Boeing Special Attention Service Bulletin 757-53-0097, Revision 3, 
dated December 2, 2016.
    (2) Installation of Supplemental Type Certificate (STC) 
ST01518SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgSTC.nsf/0/38B606833BBD98B386257FAA00602538?OpenDocument&Highlight=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.

(d) Subject
