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.
sradovich on DSK3GMQ082PROD with RULES
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
VerDate Sep<11>2014
16:05 Jul 20, 2017
Jkt 241001
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
PO 00000
Frm 00007
Fmt 4700
Sfmt 4700
33781
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.

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.
