| aircraft | Sikorsky | S-92A | Airworthiness Directives; Sikorsky Aircraft Corporation (Sikorsky) Helicopters |
Unsafe Condition
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.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Within 5 hours time-in-service, inspect the electrical wires and hydraulic lines in the upper deck for chafing. Replace unairworthy wires or lines if chafing is found. Within 5 hours TIS, inspect each clamp for correct installation as shown in Figures 1 through 13 of ASB No. 92-20-001. If clamps are incorrectly installed or missing, install them following the Accomplishment Instructions in the ASB. After each maintenance requiring clamp removal, repeat the inspections.

-----------------------------------------------------------------------
SUMMARY: The FAA is revising airworthiness directive (AD) 2014-07-04
that published in the Federal Register to correct certain errors. AD
2014-07-04 applied to certain Sikorsky Model S-92A helicopters. The
range of serial numbers in the Applicability section and a reference to
the service information in the Required Actions section of the
regulatory text are incorrect. This document corrects those errors. In
all other respects, the original document remains the same.
DATES: This final rule is effective September 30, 2014.
The Director of the Federal Register approved the incorporation by
reference of a certain document listed in this AD as of May 1, 2014 (79
FR 21385, April 16, 2014).
We must receive comments on this AD by November 14, 2014.
ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The address for the

SUPPLEMENTARY INFORMATION:
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments prior to it becoming effective. However, we
invite you to participate in this rulemaking by submitting written
comments, data, or views. We also invite comments relating to the
economic, environmental, energy, or federalism impacts that resulted
from adopting this AD. The most helpful comments reference a specific
portion of the AD, explain the reason for any recommended change, and
include supporting data. To ensure the docket does not contain
duplicate comments, commenters should send only one copy of written
comments, or if comments are filed electronically, commenters should
submit them only one time. We will file in the docket all comments that
we receive, as well as a report summarizing each substantive public
contact with FAA personnel concerning this rulemaking during the
comment period. We will consider all the comments we receive and may
conduct additional rulemaking based on those comments.
Discussion
AD 2014-07-04, Amendment 39-17818 (79 FR 21385, April 16, 2014),
applied to certain Sikorsky Model S-92A helicopters and required, in
part, repetitively inspecting each clamp for correct installation. Due
to typographical errors when the AD was published, an incorrect serial
number and an incorrect reference to the service information appeared
in the text of the rule.
Specifically, AD 2014-07-04 included the following under paragraph
(a) in the Applicability section: ``This AD applies to Model S-92A
helicopters, serial numbers 92006 through 920084, certificated in any
category.'' As published, the reference to serial number ``92006'' is
incorrect and should be serial number ``920006.''
AD 2014-07-04 also included the following under paragraph (e)(2) in
the Required Actions section: ``(2) Within 5 hours TIS, inspect each
clamp for correct installation as shown in Figures 1 through 14 of
Sikorsky Aircraft Corporation Alert Service Bulletin No. 92-20-001,
dated October 27, 2005 (ASB). If clamps are incorrectly installed or
missing, before further flight, install clamps by following the
Accomplishment Instructions, paragraphs 3.A.(4) through 3.A.(17) of the
ASB.'' As published, the reference to ``Figures 1 through 14'' is
incorrect because there are only 13 figures in the service information.
The FAA has determined that it is appropriate to take action to
revise AD 2014-07-04 to correct the serial numbers and figure
reference. This revision ensures that this AD only applies to those
aircraft subject to the unsafe condition and that it is possible for
operators to comply with the AD by referencing the correct portions of
the service information.
No other part of the preamble or regulatory information has been
changed. The final rule is being reprinted in its entirety for the
convenience of affected operators.
Impact of the Correction
Since this action reduces the number of helicopters to which the AD
is applicable and corrects an obvious error in referencing the service
information, it has no adverse economic impact and imposes no
additional burden on any person. Therefore, we find that notice and
opportunity for prior public comment are unnecessary and that good
cause exists for making this amendment effective in less than 30 days.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the

chafing between electrical wires and hydraulic lines. If there is
chafing between electrical wires and hydraulic lines, before further
flight, replace the unairworthy wires or lines with airworthy wires
or lines.
