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.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 3, 
2012 (77 FR 52212, August 29, 2012).
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of May 
24, 2004 (69 FR 25481, May 7, 2004).

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FR 52212, August 29, 2012), which superseded AD 2004-09-32, Amendment 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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:

                                                                     Estimated Costs

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.

specified in paragraph (i) or (l) of this AD, or doing the 
preventive modification specified in paragraph (j) of this AD, 
terminates the inspections required by this paragraph.
    (1) Do a high frequency eddy current (HFEC) inspection for 
cracking of the fuselage skin around the adjacent fasteners.
    (2) Do an HFEC inspection for cracking along the edge of the 
skin and bear strap.
    (3) Do a low frequency eddy current (LFEC) inspection for 
cracking of the bear strap around each fastener.

(h) Retained Repetitive Inspections and Terminating Modification When 
No Crack Is Detected

    This paragraph restates the requirements of paragraph (h) of AD 
2012-15-15, Amendment 39-17144 (77 FR 52212, August 29, 2012), with 
a terminating modification. If no crack is detected during any 
inspection required by paragraph (g) of this AD: Repeat the 
inspections required by paragraph (g) of this AD at intervals not to 
exceed 1,400 flight cycles, until the requirements of paragraph (k) 
of this AD are done. Doing the repair specified in paragraph (i) or 
(l) of this AD, or doing the preventive modification specified in
