Amendment 39-17292; AD 2012-25-11]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
for certain The Boeing Company Model 757-200, -200CB, and -300 series
airplanes. That AD currently requires initial and repetitive
inspections of the fuselage skin and bear strap at the forward, upper
corner of the L1 entry door cutout for cracking, and repair if
necessary. That action also provides an optional terminating action for
the repetitive inspections. That AD also requires additional
inspections for airplanes having repairs or preventative modifications
installed and inspections for certain other airplanes. This AD requires
the previous actions with additional airplane group configurations
added to paragraph (n) of this AD. This AD was prompted by a
determination that certain airplane group configurations in paragraph
(n) of the existing AD were inadvertently removed in the final rule. We
are issuing this AD to detect and correct cracking of the fuselage skin
and bear strap at the forward upper corner of the L1 entry door cutout,
which could result in reduced structural integrity of the L1 entry
door, and consequent rapid decompression of the airplane.
DATES: This AD is effective January 10, 2013.

SUPPLEMENTARY INFORMATION:
Discussion
On July 23, 2012, we issued AD 2012-15-15, Amendment 39-17144 (77
FR 52212, August 29, 2012), which superseded AD 2004-09-32, Amendment
39-13622 (69 FR 25481, May 7, 2004), for certain The Boeing Company
Model 757-200, -200CB, and -300 series airplanes. AD 2012-15-15
requires initial and repetitive inspections of the fuselage skin and
bear strap at the forward, upper corner of the L1 entry door cutout for
cracking, and repair if necessary. That action also provides an
optional terminating action for the repetitive inspections. That AD
also requires additional inspections for airplanes having repairs or
preventative modifications installed and inspections for certain other
airplanes. That AD resulted from reports of additional cracking in the
fuselage skin. We issued that AD to detect and correct cracking of the
fuselage skin and bear strap at the forward upper corner of the L1
entry door cutout, which could result in reduced structural integrity
of the L1 entry door, and consequent rapid decompression of the
airplane.
Actions Since AD Was Issued
Since we issued AD 2012-15-15, Amendment 39-17144 (77 FR 52212,
August 29, 2012), it was noted that certain airplane group
configurations included in paragraph (n) of the NPRM were inadvertently
removed in the final rule. This AD includes Group 1, Configuration 4,
and Group 2, Configuration 3, in paragraph (n) of this AD.
FAA's Determination
We are issuing 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.
AD Requirements
This AD requires retaining all requirements of AD 2012-15-15,
Amendment 39-17144 (77 FR 52212, August 29, 2012).
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this
[[Page 75828]]
rule because all actions of AD 2012-15-15, Amendment 39-17144 (77 FR
52212, August 29, 2012), are retained and include certain airplane
group configurations in paragraph (n) of this AD that were specified in
the NPRM (76 FR 81890, December 29, 2011), but were inadvertently
removed in the final rule of AD 2012-15-15. Therefore, we find that
notice and opportunity for prior public comment are unnecessary and
that good cause exists for making this amendment effective in less than
30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments before it becomes effective. However, we invite
you to send any written data, views, or arguments about this AD. Send
your comments to an address listed under the ADDRESSES section. Include
the docket number FAA-2012-1228 and directorate identifier 2012-NM-190-
AD at the beginning of your comments. We specifically invite comments
on the overall regulatory, economic, environmental, and energy aspects
of this AD. We will consider all comments received by the closing date
and may amend this AD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
Costs of Compliance
We estimate that this AD affects 591 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
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.
