We are superseding Airworthiness Directive (AD) 2014-07-04R1 for certain Model S-92A helicopters. AD 2014-07-04R1 required repetitive inspections in the upper deck area for incorrectly installed clamps and chafing between the electrical wires and the hydraulic lines and replacing any unairworthy wires or hydraulic lines. This new AD requires altering the wiring system in the upper deck area to correct the unsafe condition described in AD 2014-07-04R1. We are issuing this AD to prevent a fire in an area of the helicopter without extinguishing capability and subsequent loss of control of the helicopter.

Airworthiness Directives; Sikorsky Aircraft Corporation 
(Sikorsky) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-07-04R1 
for certain Model S-92A helicopters. AD 2014-07-04R1 required 
repetitive inspections in the upper deck area for incorrectly installed 
clamps and chafing between the electrical wires and the hydraulic lines 
and replacing any unairworthy wires or hydraulic lines. This new AD 
requires altering the wiring system in the upper deck area to correct 
the unsafe condition described in AD 2014-07-04R1. We are issuing this 
AD to prevent a fire in an area of the helicopter without extinguishing 
capability and subsequent loss of control of the helicopter.

DATES: This AD is effective May 5, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 5, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to remove AD 2014-07-04R1, Amendment 39-17964 (79 FR 54893, 
September 15, 2014) and add a new AD. AD 2014-07-04R1 applied to 
certain serial-numbered Sikorsky S92A helicopters and required 
repetitively inspecting the upper deck area for incorrectly installed 
clamps and for chafing between the electrical wires and hydraulic 
lines.
    The NPRM published in the Federal Register on September 25, 2015 
(80 FR 57751). The NPRM was prompted by an alteration developed by 
Sikorsky that separates and re-routes the engine inlet feeder lines. 
The NPRM proposed to require this alteration to prevent chafing between 
the electrical lines and hydraulic hoses, which could result in a fire 
in an area of the helicopter without extinguishing capability and 
subsequent loss of control of the helicopter.
    Since the NPRM was issued, the mailing address for the Boston 
Aircraft Certification Office has changed. We have revised this contact 
information in this final rule to reflect the new mailing address.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM (80 FR 57751, 
September 25, 2015).

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 
helicopters of these same type designs and that air safety and the 
public interest require adopting the AD requirements as proposed.

Related Service Information Under 1 CFR Part 51

    Sikorsky has issued Special Service Instructions SSI No. 92-070A, 
Revision A, dated April 25, 2014 (SSI 92-070A), which contains 
procedures to alter the wiring system in the upper deck area to prevent 
chafing. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by means identified in the ADDRESSES section.

Other Related Service Information

    We also reviewed Sikorsky Alert Service Bulletin ASB 92-20-003, 
Basic Issue, dated May 5, 2014 (ASB 92-20-003). ASB 92-20-003 specifies 
a one-time modification of the upper deck wiring harnesses to prevent 
possible chafing by complying with SSI 92-070A.

Differences Between This AD and the Service Information

    The service information provides a compliance date of November 5, 
2015; this AD requires a compliance time of 150 hours time-in-service. 
Also, the service information requires submitting

[[Page 18468]]

certain documentation to the manufacturer, and this AD does not.

Costs of Compliance

    We estimate that this AD will affect 20 helicopters of U.S. 
Registry.
    We estimate that operators may incur the following costs in order 
to comply with this AD. Labor costs are estimated at $85 per work-hour. 
Rerouting the upper deck wiring system and replacing and installing new 
parts will take 58 work-hours and $8,000 in required parts, for a total 
cost of $12,930 per helicopter and $258,600 for the 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

    We have determined that 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 a regulatory distinction is required, 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.

adding the following new AD:

2016-07-01 Sikorsky Aircraft Corporation: Amendment 39-18446; Docket 
No. FAA-2015-3942; Directorate Identifier 2014-SW-064-AD.

(b) Unsafe Condition

    This AD defines the unsafe condition as an incorrectly installed 
clamp that does not provide adequate clearance to prevent chafing 
between the high voltage electrical lines and the hydraulic hoses. 
This condition could result in a fire in an area of the helicopter 
without extinguishing capability and subsequent loss of control of 
the helicopter.

(c) Affected ADs

    This AD supersedes AD 2014-07-04R1, Amendment 39-17964 (79 FR 
54893, September 15, 2014).

(d) Effective Date

    This AD becomes effective May 5, 2016.
