[Docket No. FAA–2016–7426; Directorate Identifier 2015–NM–199–AD] RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737–100, –200, and –200C series airplanes. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require repetitive detailed, SUMMARY: PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 45075 high frequency eddy current (HFEC), and ultrasonic inspections of the center section rear spar upper clevis lugs and horizontal stabilizer rear spar upper lugs, as applicable, for any cracking, and related investigative and corrective actions if necessary. For certain airplanes, this proposed AD would require replacement of the center section rear spar upper chord with a new part and a serviceable center section assembly. This proposed AD would also require repetitive HFEC and fluorescent dye penetrant inspections of the center section for cracking of the front and rear spar upper clevis lugs or horizontal stabilizer front and rear spar upper lugs, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct cracking in the rear spar upper clevis lugs of the center section, and in the rear spar upper lugs of the horizontal stabilizer which could result in the loss of structural integrity and controllability of the airplane.

SUPPLEMENTARY INFORMATION: mstockstill on DSK3G9T082PROD with PROPOSALS Comments Invited We invite you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2016–7426; Directorate Identifier 2015– NM–199–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion As described in FAA Advisory Circular 120–104 (https://www.faa.gov/ documentLibrary/media/Advisory_ Circular/120-104.pdf), several programs have been developed to support initiatives that will ensure the continued airworthiness of aging airplane structure. The last element of those initiatives is the requirement to establish a LOV of the engineering data that support the structural maintenance program under 14 CFR 26.21. This proposed AD is the result of an assessment of the previously established programs by the DAH during the process of establishing the LOV for the affected airplanes. The actions specified in this proposed AD are necessary to complete certain programs to ensure the continued airworthiness of aging airplane structure and to support an airplane reaching its LOV. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its LOV of the engineering data that support the established structural maintenance program. An operator detected a cracked center section at the rear spar upper chord clevis lug. This condition, if not corrected, could result in cracking in the rear spar clevis lugs of the horizontal stabilizer center section, which could result in loss of structural integrity and controllability of the airplane. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 737–55A1033, Revision 2, dated August 7, 2015. The service information describes procedures for repetitive detailed, HFEC, and ultrasonic inspections of the center section rear spar upper clevis lugs and rear spar upper lugs of the horizontal stabilizer; HFEC and fluorescent dye penetrant inspections for cracking in the front and rear spar upper clevis lugs of the center section and the front and rear spar upper lugs of the horizontal stabilizer. For certain airplanes, the service information describes procedures for replacement of the center section rear spar upper chord with a new part and replacing the center section with a serviceable center section assembly, or installing bushings and sleeves as applicable. 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, except as discussed under ‘‘Differences Between This Proposed AD and the Service Information.’’ 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– 7426. The phrase ‘‘related investigative actions’’ is used in this NPRM. Related investigative actions are follow-on actions that (1) are related to the primary action, and (2) further investigate the nature of any condition found. Related investigative actions in an AD could include, for example, inspections. The phrase ‘‘corrective actions’’ is also used in this NPRM. Corrective actions are actions that correct or address any condition found. Corrective actions in an AD could include, for example, repairs. Differences Between This Proposed AD and the Service Information Boeing Alert Service Bulletin 737– 55A1033, Revision 2, dated August 7, 2015, specifies to contact the manufacturer for certain instructions, but this proposed AD would require accomplishment of repair methods, modification deviations, and alteration deviations in one of the following ways: • In accordance with a method that we approve; or • Using data that meet the certification basis of the airplane, and that have been approved by the Boeing Commercial Airplanes Organization Designation Authorization (ODA) whom we have authorized to make those findings. Where Boeing Alert Service Bulletin 737–55A1033, Revision 2, dated August 7, 2015, specifies a compliance time or repeat interval as ‘‘Horizontal Stabilizer Center Section flight cycles’’ or ‘‘Horizontal Stabilizer flight cycles,’’ this AD requires compliance for the corresponding time or repeat interval in airplane flight cycles. Costs of Compliance We estimate that this proposed AD affects 84 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Repetitive detailed, HFEC, and ultrasonic inspections. 9 work-hours × $85 per hour = $765 per inspection cycle.

Repair and replacement ....................................... 101 work-hours × $85 per hour = $8,585 ............ $0 Up to 252 work-hours × $85 per hour = $21,420 per inspection cycle. 25,000 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. mstockstill on DSK3G9T082PROD with PROPOSALS We 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 this proposed regulation: (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 18:07 Jul 11, 2016 (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.

Background Over the last few years, we have revised many of our regulations to bolster program integrity and clarify our policy, procedures, and expectations. For example, on June 25, 2014, we made changes to when a claimant must object to appearing at a hearing by video teleconferencing.1 As another example, we published a final rule on March 20, 2015, that clarified a claimant’s duty to inform us about or submit all evidence that relates to whether or not he or she is blind or disabled, subject to two exceptions for privileged communications.2 We made these and other changes specifically to strengthen the integrity of our programs. As we explained in the final rule on March 20, 2015, ‘‘we believe program integrity requires us to obtain complete medical evidence (favorable or unfavorable) in disability claims.’’ 3 Although that statement refers to medical evidence, we reiterate in this proposed rule that a complete evidentiary record is necessary for us to make an informed and accurate disability determination or decision, and bolsters program integrity by improving consistency in the adjudication of claims at all levels of the administrative review process. As we look ahead, we continue to evaluate our regulatory and sub-regulatory policies to assess where we can make changes to improve accuracy and efficiency in our administrative review processes. To that end, we are now proposing the changes outlined below. As we discuss in detail below, we have now had time to implement helpful systems changes and review a study performed by the Administrative Conference of the United States (ACUS), in which ACUS evaluated available data and considered various internal and external stakeholder opinions about the impact of our Part 405 rules.4 We are 1 79 FR 35926. 80 FR 14828, 20 CFR 404.1512, 416.912. 3 80 FR at 14833. 4 See Report from Office of the Chairman of the Administrative Conference of the United States, SSA Disability Benefits Adjudication Process: Assessing the Impact of the Region 1 Pilot Program (Dec. 23, 2013) (‘‘ACUS Report’’), available at https://acus.gov/sites/default/files/documents/ Assessing%20Impact%20of%20Region%20 I%20Pilot%20Program%20Report_12_23_13_ final.pdf.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 737-100, -200, and -200C series 
airplanes. This proposed AD is intended to complete certain mandated 
programs intended to support the airplane reaching its limit of 
validity (LOV) of the engineering data that support the established 
structural maintenance program. This proposed AD would require 
repetitive detailed, high frequency eddy current (HFEC), and ultrasonic 
inspections of the center section rear spar upper clevis lugs and 
horizontal stabilizer rear spar upper lugs, as applicable, for any 
cracking, and related investigative and corrective actions if 
necessary. For certain airplanes, this proposed AD would require 
replacement of the center section rear spar upper chord with a new part 
and a serviceable center section assembly. This proposed AD would also 
require repetitive HFEC and fluorescent dye penetrant inspections of 
the center section for cracking of the front and rear spar upper clevis 
lugs or horizontal stabilizer front and rear spar upper lugs, and 
related investigative and corrective actions if necessary. We are 
proposing this AD to detect and correct cracking in the rear spar upper 
clevis lugs of the center section, and in the rear spar upper lugs of 
the horizontal stabilizer which could result in the loss of structural 
integrity and controllability of the airplane.

DATES: We must receive comments on this proposed AD by August 26, 2016.

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

SUPPLEMENTARY INFORMATION:

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2016-7426; 
Directorate Identifier 2015-NM-199-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD because of those comments.
    We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this proposed AD.

Discussion

    As described in FAA Advisory Circular 120-104 (https://www.faa.gov/documentLibrary/media/Advisory_Circular/120-104.pdf), several programs 
have been developed to support initiatives that will ensure the 
continued airworthiness of aging airplane structure. The last element 
of those initiatives is the requirement to establish a LOV of the 
engineering data that support the structural maintenance program under 
14 CFR 26.21. This proposed AD is the result of an assessment of the 
previously established programs by the DAH during the process of 
establishing the LOV for the affected airplanes. The actions specified 
in this proposed AD are necessary to complete certain programs to 
ensure the continued airworthiness of aging airplane structure and to 
support an airplane reaching its LOV.
    This proposed AD is intended to complete certain mandated programs 
intended to support the airplane reaching its LOV of the engineering 
data that support the established structural maintenance program. An 
operator detected a cracked center section at the rear spar upper chord 
clevis lug. This condition, if not corrected, could result in cracking 
in the rear spar clevis lugs of the horizontal stabilizer center 
section, which could result in loss of structural integrity and 
controllability of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 737-55A1033, Revision 2, 
dated August 7, 2015. The service information describes procedures for 
repetitive detailed, HFEC, and ultrasonic inspections of the center 
section rear spar upper clevis lugs and rear spar upper lugs of the 
horizontal stabilizer; HFEC and fluorescent dye penetrant inspections 
for cracking in the front and rear spar upper clevis lugs of the center 
section and the front and rear spar upper lugs of the horizontal 
stabilizer. For certain airplanes, the service information describes 
procedures for replacement of the center section rear spar upper chord 
with a new part and replacing the center section with a serviceable 
center section assembly, or installing bushings and sleeves as 
applicable. 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, except as discussed 
under ``Differences Between This Proposed AD and the Service 
Information.'' 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-2016-7426.
    The phrase ``related investigative actions'' is used in this NPRM. 
Related investigative actions are follow-on actions that (1) are 
related to the primary action, and (2) further investigate the nature 
of any condition found. Related investigative actions in an AD could 
include, for example, inspections.
    The phrase ``corrective actions'' is also used in this NPRM. 
Corrective actions are actions that correct or address any condition 
found. Corrective actions in an AD could include, for example, repairs.

Differences Between This Proposed AD and the Service Information

    Boeing Alert Service Bulletin 737-55A1033, Revision 2, dated August 
7, 2015, specifies to contact the manufacturer for certain 
instructions, but this proposed AD would require accomplishment of 
repair methods, modification deviations, and alteration deviations in 
one of the following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) whom we have 
authorized to make those findings.
    Where Boeing Alert Service Bulletin 737-55A1033, Revision 2, dated 
August 7, 2015, specifies a compliance time or repeat interval as 
``Horizontal Stabilizer Center Section flight cycles'' or ``Horizontal 
Stabilizer flight cycles,'' this AD requires compliance for the 
corresponding time or repeat interval in airplane flight cycles.

Costs of Compliance

    We estimate that this proposed AD affects 84 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    We estimate the following costs to do any necessary inspections, 
repairs, and replacements that would be required based on the results 
of the proposed inspection. We have no way of determining the number of 
aircraft that might need these inspections, repairs, and replacements:

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 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 this proposed 
regulation:
    (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.
