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 installing an engine flame detector bracket assembly and 
harness assembly. This AD was prompted by reports of false fire 
warnings. The actions of this AD are intended to prevent an unsafe 
condition on these products.

DATES: This AD is effective August 25, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain documents listed in this AD as of August 25, 2017.

ADDRESSES: For service information identified in this final rule,

SUPPLEMENTARY INFORMATION:

Discussion

    On December 27, 2016, at 81 FR 95066, 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 Sikorsky Model 
S-92A helicopters, serial numbers 920006 through 920298. The NPRM 
proposed to require installing a No. 2 engine outboard flame detector 
bracket assembly (bracket) and a No. 2 engine flame detector harness 
assembly (harness), if not already installed or if the bracket was not 
installed before the harness. The proposed AD was prompted by reports 
of false fire indications from the No. 2 engine outboard flame 
detectors. The proposed requirements were intended to prevent a false 
fire warning, which could result in an unnecessary emergency landing or 
ditching.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no 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 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

    We reviewed Sikorsky S-92 Customer Service Notice 92-094, Revision 
B, dated June 14, 2016, which provides procedures for installing 
harness part number (P/N) 92310-04201-041.
    We also reviewed Sikorsky Special Service Instructions No. 92-107G, 
Revision G, dated February 25, 2016, (SSI No. 92-107G) which specifies 
installing new brackets, P/N 92070-30033-011, 92070-30033-014, and 
92070-30033-015, to increase the stability of the No. 2 engine outboard 
flame detector.
    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.

Other Related Service Information

    We reviewed Sikorsky S-92 Alert Service Bulletin (ASB) 92-26-006, 
Basic Issue, dated February 25, 2016. This service information provides 
instructions for installing a new bracket by complying with SSI No. 92-
107G. We also reviewed S-92 ASB 92-26-007, Basic Issue, dated June 14, 
2016. This service information specifies installing harness P/N 92310-
04201-041 after or concurrently with the new bracket.

Costs of Compliance

    We estimate that this AD affects 50 helicopters of U.S. Registry 
and that labor costs average $85 per work-hour. Based on these 
estimates, we expect that installing a new bracket and harness requires 
15.25 work hours for a labor cost of about $1,296. Parts cost $100 for 
a total cost of about $1,396 per helicopter and $69,800 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.
