[FR Doc. 2016–03135 Filed 2–17–16; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration wgreen on DSK2VPTVN1PROD with PROPOSALS 14 CFR Part 39 [Docket No. FAA–2016–3697; Directorate Identifier 2015–NM–143–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. AGENCY: VerDate Sep<11>2014 14:30 Feb 17, 2016 Jkt 238001 Notice of proposed rulemaking (NPRM). ACTION: We propose to supersede Airworthiness Directive (AD) 2011–01– 15, which applies to certain The Boeing Company Model 757–200, –200CB, and –300 series airplanes. AD 2011–01–15 currently requires repetitive inspections for cracking of the fuselage skin of the crown skin panel along the chem-milled step at stringers S–4L (left) and S–4R (right), from stations (STA) 297 through STA 439, and repair, if necessary. AD 2011–01–15 also includes terminating action for the repetitive inspections of the repaired areas only. Since we issued AD 2011–01–15, we received 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. This proposed AD would add repetitive inspections for cracking in additional areas and repair if necessary. This proposed AD would also remove airplanes from the applicability in AD 2011–01–15. This proposed AD would also add an optional skin panel replacement which would terminate all inspections and an optional preventative modification that would terminate certain inspections. We are proposing this AD to detect and correct fatigue cracking of the fuselage skin of the crown skin panel, which could result in pressure venting and consequent rapid decompression of the airplane. DATES: We must receive comments on this proposed AD by April 4, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Discussion On December 28, 2010, we issued AD 2011–01–15, Amendment 39–16572 (76 FR 1351, January 10, 2011), for certain The Boeing Company Model 757–200, –200CB, and –300 series airplanes. AD 2011–01–15 requires repetitive inspections for cracking of the fuselage skin of the crown skin panel along the E:\FR\FM\18FEP1.SGM 18FEP1 8158 Federal Register / Vol. 81, No. 32 / Thursday, February 18, 2016 / Proposed Rules chem-milled step at stringers S–4L and S–4R, from stations (STA) 297 through STA 439, and repair if necessary. AD 2011–01–15 also includes 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. We issued AD 2011–01–15 to detect and correct fatigue cracking of the fuselage skin of the crown skin panel, which could result in pressure venting and consequent rapid decompression of the airplane. Actions Since AD 2011–01–15, Amendment 39–16572 (76 FR 1351, January 10, 2011), Was Issued The preamble to AD 2011–01–15, Amendment 39–16572 (76 FR 1351, January 10, 2011), specifies that we consider the requirements ‘‘interim action.’’ AD 2011–01–15 explains that we might consider further rulemaking if final action is later identified. We now have determined that it is necessary to initiate further rulemaking to add repetitive inspections for cracking in additional areas for certain airplanes, and repair if necessary. We have removed Model 757–200 CB series airplanes from the applicability because the crown skins on those airplanes are manufactured differently and therefore are not affected by the identified unsafe condition. We have also determined that the external detailed inspection that is allowed as an option in AD 2011–01–15, Amendment 39–16572 (76 FR 1351, January 12, 2011), does not adequately address the identified unsafe condition. Only eddy current inspections are adequate to address the identified unsafe condition. the service information described previously. For information on the procedures and compliance times, see this service information at https:// www.regulations.gov by searching for and locating Docket No. FAA–2016– 3697. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Special Attention Service Bulletin 757–53– 0097, Revision 2, dated July 28, 2015. The 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. Explanation of ‘‘RC’’ Steps in Service Information 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 FAA worked in conjunction with industry, under the Airworthiness Directive Implementation Aviation Rulemaking Committee (ARC), to enhance the AD system. One enhancement was a new process for annotating which steps in the service information are required for compliance with an AD. Differentiating these steps from other tasks in the service information is expected to improve an owner’s/operator’s understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The steps identified as RC (required for compliance) in any service information identified previously have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition. Costs of Compliance We estimate that this proposed AD affects 652 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Parts cost Inspections (Zone 1) [Retained actions from AD 2011–01–15, Amendment 39-16572 (76 FR 1351, January 10, 2011)]. Inspections (Zones 2 and 3) [new proposed action]. Optional modification ............................ wgreen on DSK2VPTVN1PROD with PROPOSALS Labor cost 2 work-hour × $85 per hour = $170 per inspection cycle. $0 .......................... $170 per inspection cycle. $110,840 per inspection cycle. Up to 4 work-hours × $85 per hour = Up to $340 per inspection cycle. Up to 615 work-hours × $85 per hour = Up to $52,275. $0 .......................... Up to $340 per inspection cycle. Up to $78,771 ....... $221,680 per inspection cycle. Up to $51,358,692. We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this proposed AD. We have received no definitive data that would enable us to provide a cost estimate for the optional replacement 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 VerDate Sep<11>2014 14:30 Feb 17, 2016 Jkt 238001 Up to $26,496 ....... 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 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 Cost per product Cost on U.S. operators Action products identified in this rulemaking action. Regulatory Findings We have 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 that the proposed regulation: E:\FR\FM\18FEP1.SGM 18FEP1 Federal Register / Vol. 81, No. 32 / Thursday, February 18, 2016 / Proposed Rules (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 Air transportation, Aircraft, Aviation safety, Incorporation by 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 1.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330–200 and –300 series airplanes; and Model A340–200 and –300 series airplanes. This proposed AD was prompted by a determination that the compliance times for certain postrepair inspections and certain allowable damage limits (ADLs) must be reduced in order to address fatigue. This proposed AD would require identifying any repairs and ADLs used to assess or control any structural damage on certain structural areas, and corrective action if necessary. We are proposing this AD to prevent fatigue damage on primary structure and structural repairs, which could result in reduced structural integrity of the airplane. DATES: We must receive comments on this proposed AD by April 4, 2016. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2011-01-
15, which applies to certain The Boeing Company Model 757-200, -200CB, 
and -300 series airplanes. AD 2011-01-15 currently requires repetitive 
inspections for cracking of the fuselage skin of the crown skin panel 
along the chem-milled step at stringers S-4L (left) and S-4R (right), 
from stations (STA) 297 through STA 439, and repair, if necessary. AD 
2011-01-15 also includes terminating action for the repetitive 
inspections of the repaired areas only. Since we issued AD 2011-01-15, 
we received 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. This proposed AD would add 
repetitive inspections for cracking in additional areas and repair if 
necessary. This proposed AD would also remove airplanes from the 
applicability in AD 2011-01-15. This proposed AD would also add an 
optional skin panel replacement which would terminate all inspections 
and an optional preventative modification that would terminate certain 
inspections. We are proposing this AD to detect and correct fatigue 
cracking of the fuselage skin of the crown skin panel, which could 
result in pressure venting and consequent rapid decompression of the 
airplane.

DATES: We must receive comments on this proposed AD by April 4, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    On December 28, 2010, we issued AD 2011-01-15, Amendment 39-16572 
(76 FR 1351, January 10, 2011), for certain The Boeing Company Model 
757-200, -200CB, and -300 series airplanes. AD 2011-01-15 requires 
repetitive inspections for cracking of the fuselage skin of the crown 
skin panel along the

[[Page 8158]]

chem-milled step at stringers S-4L and S-4R, from stations (STA) 297 
through STA 439, and repair if necessary. AD 2011-01-15 also includes 
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. We issued AD 2011-01-15 to detect and 
correct fatigue cracking of the fuselage skin of the crown skin panel, 
which could result in pressure venting and consequent rapid 
decompression of the airplane.

Actions Since AD 2011-01-15, Amendment 39-16572 (76 FR 1351, January 
10, 2011), Was Issued

    The preamble to AD 2011-01-15, Amendment 39-16572 (76 FR 1351, 
January 10, 2011), specifies that we consider the requirements 
``interim action.'' AD 2011-01-15 explains that we might consider 
further rulemaking if final action is later identified. We now have 
determined that it is necessary to initiate further rulemaking to add 
repetitive inspections for cracking in additional areas for certain 
airplanes, and repair if necessary.
    We have removed Model 757-200 CB series airplanes from the 
applicability because the crown skins on those airplanes are 
manufactured differently and therefore are not affected by the 
identified unsafe condition.
    We have also determined that the external detailed inspection that 
is allowed as an option in AD 2011-01-15, Amendment 39-16572 (76 FR 
1351, January 12, 2011), does not adequately address the identified 
unsafe condition. Only eddy current inspections are adequate to address 
the identified unsafe condition.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 757-53-0097, 
Revision 2, dated July 28, 2015. The 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.

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. For information on the 
procedures and compliance times, see this service information at https://www.regulations.gov by searching for and locating Docket No. FAA-2016-
3697.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(ARC), to enhance the AD system. One enhancement was a new process for 
annotating which steps in the service information are required for 
compliance with an AD. Differentiating these steps from other tasks in 
the service information is expected to improve an owner's/operator's 
understanding of crucial AD requirements and help provide consistent 
judgment in AD compliance. The steps identified as RC (required for 
compliance) in any service information identified previously have a 
direct effect on detecting, preventing, resolving, or eliminating an 
identified unsafe condition.

Costs of Compliance

    We estimate that this proposed AD affects 652 airplanes of U.S. 
registry.
    We estimate the following costs to comply with 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 have 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 that the proposed 
regulation:

[[Page 8159]]

    (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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the

2011, which is not incorporated by reference in this AD.

(m) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles 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 (m)(1) of this AD. 
Information may be emailed to: 9-ANM-LAACO-AMOC-Requests@faa.gov.
    (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, to make those findings. For a repair 
method 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) AMOCs approved for AD 2011-01-15, Amendment 39-16572 (76 FR 
1351, January 10, 2011), are not approved as AMOCs for the 
corresponding provisions of paragraph (g) of this AD.
    (5) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(m)(5)(i) and (m)(5)(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.
