Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

––––––––––––––––––––––––––––––––––

SUMMARY: We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation
(Sikorsky) Model S-92A helicopters. This AD requires altering the fire bottle inertia switch wiring
and performing a cartridge functional test of the fire extinguishing system. This AD was prompted by
the inadvertent tripping of inertia-switches that has led to unintentional discharging of the fire bottles,
leaving the helicopter's auxiliary power unit and engines without fire protection. The actions are
intended to prevent unintentional and undetected fire bottle discharges and subsequent unavailability
of fire suppression in case of a fire.

DATES: This AD is effective November 22, 2016.
The Director of the Federal Register approved the incorporation by reference of a certain
document listed in this AD as of November 22, 2016.

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;
(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.

SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company
Model 747-400, 747-400D, and 747-400F series airplanes. This AD was prompted by a
determination that a certain fastener type in the fuel tank walls has insufficient bond to the structure,
and an electrical wiring short could cause arcing to occur at the ends of fasteners in the fuel tanks.
This AD requires the installation of new clamps and polytetrafluoroethylene (TFE) sleeves on the
wire bundles of the front spars and rear spars of the wings. This AD also requires inspecting the
existing TFE sleeves under the wire bundle clamps for correct installation, and replacement if
necessary. We are issuing this AD to prevent potential ignition sources in the fuel tank in the event of
a lightning strike or high-powered short circuit, and consequent fire or explosion.

DATES: This AD is effective November 14, 2016.
The Director of the Federal Register approved the incorporation by reference of a certain
publication listed in this AD as of November 14, 2016.

SUPPLEMENTARY INFORMATION:

Discussion

     We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD
that would apply to certain The Boeing Company Model 747-400, 747-400D, and 747-400F series
airplanes. The NPRM published in the Federal Register on March 1, 2016 (81 FR 10537) (''the
NPRM''). The NPRM was prompted by a determination that a certain fastener type in the fuel tank
walls has insufficient bond to the structure, and an electrical wiring short could cause arcing to occur
at the ends of fasteners in the fuel tanks. The NPRM proposed to require the installation of new
clamps and TFE sleeves on the wire bundles of the front spars and rear spars of the wings. The
NPRM also proposed to require inspecting the existing TFE sleeves under the wire bundle clamps for
correct installation, and replacement if necessary. We are issuing this AD to prevent potential ignition
sources in the fuel tank in the event of a lightning strike or high-powered short circuit, and
consequent fire or explosion.

Comments

     We gave the public the opportunity to participate in developing this AD. The following presents
the comments received on the NPRM and the FAA's response to each comment.

Support for the NPRM

    Boeing supported the content of the NPRM. United Airlines had no objection to the NPRM.

Conclusion

    We reviewed the relevant data, considered the comments received, and determined that air safety
and the public interest require adopting this AD as proposed, except for minor editorial changes. We
have determined that these minor changes:
   • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe
       condition; and
   • Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 747-28-2324, Revision 1, dated July 27,
2015. The service information describes procedures for installing new clamps and TFE sleeves on the
                                                   2

wire bundles of the front spars and rear spars of the wings. The service information also describes
procedures for inspecting TFE sleeves under the wire bundle clamps that were installed using the
procedures specified in Boeing Special Attention Service Bulletin 747-28-2324, dated November 3,
2014, for correct installation, and replacing them if necessary. 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.

Costs of Compliance

We estimate that this AD affects 135 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs
Action Labor cost Parts Cost per Cost on U.S.
cost product operators
Installation of wire Up to 7 work-hours × $85 $138 Up to $733 Up to $98,955.
bundle clamps per hour = $595
Inspection Up to 5 work-hours × $85 0 Up to $425 Up to $57,375.
per hour = $425

We have received no definitive data that enables us to provide cost estimates for the on-condition
actions specified in this AD.

Authority for This Rulemaking

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.
