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.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is revising airworthiness directive (AD) 2014-07-04

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.

    This AD applies to Model S-92A helicopters, serial numbers 
920006 through 920084, certificated in any category.

(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

AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(f) Required Actions

    (1) Within 5 hours time-in-service, inspect the electrical wires 
and the hydraulic lines in the upper deck of the helicopter for 
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.
    (2) Within 5 hours TIS, inspect each clamp for correct 
installation as shown in Figures 1 through 13 of Sikorsky Aircraft 
Corporation Alert Service Bulletin No. 92-20-001, dated October 27,

further flight, install clamps by following the Accomplishment 
Instructions, paragraph 3.A.(4) through 3.A.(17) of the ASB.
    (3) After each maintenance that requires removing clamps, comply 
with paragraphs (f)(1) and (f)(2) of this AD.
