(2) Installation of Supplemental Type Certificate (STC) ST01920SE (http:// rgl.faa.gov/Regulatory_and_Guidance_ Library/rgstc.nsf/0/ 59027F43B9A7486E86257B1D006591EE? OpenDocument&Highlight=st01920se) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01920SE 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 Air Transport Association (ATA) of America Code 53, Fuselage. (e) Unsafe Condition This AD was prompted by an evaluation by the design approval holder indicating that the skin lap splice is subject to widespread fatigue damage. We are issuing this AD to detect and correct fatigue cracking of this skin lap splice, which could grow and result in possible rapid decompression and reduced structural integrity of the airplane. Lhorne on DSK30JT082PROD with RULES (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Inspection and Corrective Actions At the applicable time specified in paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 767–53A0260, dated August 26, 2014, except as required by paragraph (i) of this AD: Do a detailed inspection and a surface high frequency eddy current (HFEC) inspection at section 41, stringer S–2R skin lap splice from body station (STA) 368 to STA 434, for any cracking, and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 767–53A0260, dated August 26, 2014. Do all applicable corrective actions before further flight. Repeat the inspections thereafter at the applicable times specified in paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 767–53A0260, dated August 26, 2014. If any existing external repair is found in the inspection area, then the inspections in Part 1 of the Accomplishment Instructions of Boeing Alert Service Bulletin 767–53A0260, dated August 26, 2014, are not required in the area hidden by the repair, provided that the repair was previously approved by the Manager, Seattle Aircraft Certification Office (ACO), or by the Authorized Representative of the Boeing Commercial Airplanes Organization Designation Authorization (ODA), or installed as specified in Part 2 of the Accomplishment Instructions of Boeing Alert Service Bulletin 767–53A0260, dated August 26, 2014. Inspections in Part 1 of the Accomplishment Instructions of Boeing Alert Service Bulletin 767–53A0260, dated August VerDate Sep<11>2014 12:31 Oct 17, 2016 Jkt 241001 71591 26, 2014, remain applicable in areas not hidden by the repair. still be done as specified, and the airplane can be put back in an airworthy condition.

Repairs identified in Part 2 of Boeing Alert Service Bulletin 767–53A0260, dated August 26, 2014, specify post-repair airworthiness limitation inspections for compliance with 14 CFR 25.57l(a)(3) at the repaired locations, which support compliance with 14 CFR 121.1109(c)(2) or 129.109(b)(2). As airworthiness limitations, these inspections are required by maintenance and operational rules. It is therefore unnecessary to mandate them in this AD. Deviations from these inspections require FAA approval, but do not require an AMOC. (i) Exception to the Service Information Where Boeing Alert Service Bulletin 767– 53A0260, dated August 26, 2014, specifies a compliance time ‘‘after the original issue date of this service bulletin,’’ this AD requires compliance within the specified compliance time after the effective date of this AD.

Lhorne on DSK30JT082PROD with RULES FOR FURTHER INFORMATION CONTACT: SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 12:31 Oct 17, 2016 Jkt 241001 Discussion On May 13, 2016, at 81 FR 29817, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Sikorsky Model S–92A helicopters. Sikorsky has informed us that the inadvertent tripping of inertia switches has caused several engine and auxiliary power unit fire bottle discharges during taxi, flight, and landing operations. Because these discharges are undetected, the fire bottles remain unavailable in the event of a fire. The NPRM proposed to require altering the fire bottle inertia switch wiring to disable the automatic feature of the fire extinguishing system and performing a cartridge functional test. The proposed requirements were intended to prevent an unintentional and undetected fire bottle discharge and subsequent unavailability of fire suppression in the event of a fire. Since the NPRM was issued, the email address for Sikorsky has changed. We have revised this email address throughout this final rule. Comments We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM. FAA’s Determination We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of the same type design and that air safety and the public interest require adopting the AD requirements as proposed. Related Service Information Under 1 CFR Part 51 We reviewed Sikorsky Alert Service Bulletin 92–26–005A, Revision A, dated June 27, 2014 (ASB 92–26–005A). ASB 92–26–005A specifies performing a onetime alteration of the fire bottle inertia switch wiring to disable the automatic actuation feature of the fire extinguishing system. ASB 92–26–005A includes figures that depict the wiring and electrical connector pin changes. 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. Other Related Service Information We also reviewed Sikorsky Alert Service Bulletin 92–26–005, Basic Issue, dated June 18, 2014 (ASB 92–26–005). ASB 92–26–005 contains the same PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 procedures as ASB 92–26–005A. However, ASB 92–26–005A contains an additional figure. Differences Between This AD and the Service Information This AD has a compliance date within 90 days, and the service information has a calendar date, which has already passed. This AD does not require performing a cartridge functional test prior to alteration. The service information does specify performing a cartridge functional test prior to alteration. Costs of Compliance We estimate that this AD will affect 80 helicopters of U.S. Registry. We estimate that operators may incur the following costs to comply with this AD. Labor costs are estimated at $85 per work-hour. Altering the fire bottle switch and performing a cartridge functional test will take about 2 workhours. No parts are needed for an estimated cost of $170 per helicopter and $13,600 for the U.S. fleet. 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; E:\FR\FM\18OCR1.SGM 18OCR1 Federal Register / Vol. 81, No. 201 / Tuesday, October 18, 2016 / Rules and Regulations (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 to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:

Discussion

    On May 13, 2016, at 81 FR 29817, the Federal Register published our 
notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR 
part 39 by adding an AD that would apply to certain serial-numbered 
Sikorsky Model S-92A helicopters. Sikorsky has informed us that the 
inadvertent tripping of inertia switches has caused several engine and 
auxiliary power unit fire bottle discharges during taxi, flight, and 
landing operations. Because these discharges are undetected, the fire 
bottles remain unavailable in the event of a fire.
    The NPRM proposed to require altering the fire bottle inertia 
switch wiring to disable the automatic feature of the fire 
extinguishing system and performing a cartridge functional test. The 
proposed requirements were intended to prevent an unintentional and 
undetected fire bottle discharge and subsequent unavailability of fire 
suppression in the event of a fire.
    Since the NPRM was issued, the email address for Sikorsky has 
changed. We have revised this email address throughout this final rule.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM.

FAA's Determination

    We have reviewed the relevant information and determined that an 
unsafe condition exists and is likely to exist or develop on other 
products of the same type design and that air safety and the public 
interest require adopting the AD requirements as proposed.

Related Service Information Under 1 CFR Part 51

    We reviewed Sikorsky Alert Service Bulletin 92-26-005A, Revision A, 
dated June 27, 2014 (ASB 92-26-005A). ASB 92-26-005A specifies 
performing a one-time alteration of the fire bottle inertia switch 
wiring to disable the automatic actuation feature of the fire 
extinguishing system. ASB 92-26-005A includes figures that depict the 
wiring and electrical connector pin changes.
    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.

Other Related Service Information

    We also reviewed Sikorsky Alert Service Bulletin 92-26-005, Basic 
Issue, dated June 18, 2014 (ASB 92-26-005). ASB 92-26-005 contains the 
same procedures as ASB 92-26-005A. However, ASB 92-26-005A contains an 
additional figure.

Differences Between This AD and the Service Information

    This AD has a compliance date within 90 days, and the service 
information has a calendar date, which has already passed. This AD does 
not require performing a cartridge functional test prior to alteration. 
The service information does specify performing a cartridge functional 
test prior to alteration.

Costs of Compliance

    We estimate that this AD will affect 80 helicopters of U.S. 
Registry.
    We estimate that operators may incur the following costs to comply 
with this AD. Labor costs are estimated at $85 per work-hour. Altering 
the fire bottle switch and performing a cartridge functional test will 
take about 2 work-hours. No parts are needed for an estimated cost of 
$170 per helicopter and $13,600 for the U.S. fleet.

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;

[[Page 71593]]

    (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 to the extent 
that it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
