Download as PDF 48696 Federal Register / Vol. 79, No. 159 / Monday, August 18, 2014 / Proposed Rules deadline for agricultural production facilities issued in December 2007.13 c. Clarification of Terminology— Comments regarding the utility, clarity and accuracy of definitions currently found in 6 CFR 27.105, such as, but not limited to, the definitions of ‘‘A Commercial Grade’’ and ‘‘A Placarded Amount.’’ DHS also seeks comments on the utility of including definitions, and what those definitions should be, for the terms ‘‘material modifications,’’ ‘‘critical asset,’’ and ‘‘site asset;’’ and ‘‘inspection.’’ DHS invites comments on recommendations for additional terms used in the current CFATS regulations that may warrant further clarification. d. Risk Based Performance Standards 14—Comments on whether and how DHS should clarify or modify the 18 RBPS in 6 CFR 27.230, whether DHS should combine and/or eliminate any of the existing RBPS, and whether DHS should adopt any additional RBPS. e. Appendix A—Comments on all aspects of CFATS Appendix A, including: (1) Comments on the possible addition of chemicals to, and/or the deletion or modification of certain COI currently listed in Appendix A; (2) any term utilized in 6 CFR 27.203, and the applicability and/or modification of STQs as the bases for listing COI (e.g., by security issue(s)); and (3) the concentration and mixtures rules associated with Appendix A, which are described in 6 CFR 27.204. f. Small Business Considerations— Comments regarding considerations specific to small businesses. g. Alignment with Other Regulatory Programs—Comments regarding how the Department may be able to better align CFATS and other existing chemical facility regulations, including comments on any duplication or overlap that may exist between CFATS and another regulatory program.15 When providing comments on this topic, DHS encourages commenters to provide the specific citations to the regulatory regimes that may duplicate or overlap with the requirements under CFATS as well as a specific description of the duplicative or overlapping requirements. In addressing these topics, DHS encourages interested parties to provide specific data that documents the potential costs of modifying the existing regulatory requirements pursuant to the commenter’s suggestions; the potential quantifiable benefits including security and societal benefits of modifying the existing regulatory requirements; and the potential impacts on small businesses of modifying the existing regulatory requirements. Commenters might also address how DHS can best obtain and consider accurate, objective information and data about the costs, burdens, and benefits of the CFATS Interim Final Rule and Appendix A, and whether there are lower cost alternatives that would allow the Department to continue to achieve its security goals consistent with the law. Jeh Charles Johnson, Secretary. [FR Doc. 2014–19356 Filed 8–15–14; 8:45 am] Examining the AD Docket BILLING CODE 9110–9P–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 13 In tkelley on DSK3SPTVN1PROD with PROPOSALS December 2007, DHS exercised its discretion under the CFATS regulation by granting an indefinite extension from the Top-Screen submission deadline for agricultural production facilities that use chemicals of interest (COI) and COI-containing products for agricultural production purposes (see 73 FR 1640). Examples of agricultural production facilities include: farms, ranches and range land, livestock facilities, turf grass growers, golf courses, nurseries and floricultural operations, and public and private parks. 14 CFATS establishes eighteen Risk-Based Performance Standards (RBPSs) that identify the areas for which a facility’s security posture will be examined, such as perimeter security, access control, personnel surety, and cyber security. To meet the RBPSs, covered facilities are free to choose whatever security programs or processes they deem appropriate, so long as they achieve the requisite level of performance in each applicable area. The programs and processes that a high-risk facility ultimately chooses to implement to meet these standards must be described in the Site Security Plan (SSP) that every high-risk chemical facility must develop pursuant to the regulations. The RBPS guidance document is available online at: http://www.dhs.gov/xlibrary/assets/chemsec_cfats_ riskbased_performance_standards.pdf.

We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2013– 0182, dated August 12, 2013, to correct an unsafe condition for Airbus Helicopters Model MBB–BK 117 C–2 helicopters with a lateral duplex trim actuator, part number (P/N) 418–00878– 050 or P/N 418–00878–051, or with a longitudinal duplex trim actuator, P/N 418–00878–000 or P/N 418–00878–001. EASA advises that recent analysis has shown that under unfavorable circumstances, a total loss of the trim actuator output lever attachment screw could lead to a restriction of the lateral and longitudinal control range. According to EASA, without the attachment screw, the output lever can move in the axial direction. This condition, if not detected, could cause the bolt that connects the control rod to the output lever to make contact with actuator housing, possibly resulting in reduced control of the helicopter. To prevent this condition, EASA requires an initial torque check of the lateral and longitudinal trim actuator output level VerDate Mar<15>2010 16:52 Aug 15, 2014 Jkt 232001 attachment screws, the application of a torque marking, and repetitive inspections for correct torque thereafter. The AD’s requirements are considered an interim solution, pending a terminating modification. Since the issuance of EASA AD No. 2013–0182, Eurocopter Deutschland GmbH has changed its name to Airbus Helicopters Deutschland GmbH. FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information We reviewed Eurocopter (now Airbus Helicopters) Alert Service Bulletin MBB–BK117 C–2–67A–020, Revision 0, dated June 18, 2013 (ASB), which advises of a design review that showed that a loss of the attachment screw of the trim actuator output lever could restrict the lateral and longitudinal control range. The ASB consequently calls for an initial torque check and application of torque markings of the self-locking nuts, and subsequent repetitive inspections to maintain the proper torque. Proposed AD Requirements This proposed AD would require, within 300 hours time-in-service (TIS) and thereafter at intervals not exceeding 400 hours TIS, inspecting the lateral and longitudinal trim actuator output lever self-locking nuts for correct torque and applying torque marking. For each inspection where the nuts are not torqued to the correct value and must be adjusted, the torque marking would be removed and reapplied. Interim Action We consider this AD to be an interim action because Airbus Helicopters is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved and available, we might consider additional rulemaking. Costs of Compliance We estimate that this proposed AD would affect 100 helicopters of U.S. Registry and that labor costs average $85 PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 48697 per work-hour. Based on these estimates, we expect the following costs: Applying torque and torque marking to the lateral and longitudinal trim actuator output levers would require 1 work-hour for a labor cost of $85. No parts would be needed, so the cost for the U.S. fleet would total $8,500. Visually inspecting for correct torque would require 0.5 work-hour for a labor cost of about $43. No parts would be needed, so the total cost for the U.S. fleet would be $4,300 per inspection cycle. 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 proposed 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 determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the 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 E:\FR\FM\18AUP1.SGM 18AUP1 48698 Federal Register / Vol. 79, No. 159 / Monday, August 18, 2014 / Proposed Rules this proposed AD and placed it in the AD docket.

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Airbus Helicopters Model MBB-BK 117 C-2 helicopters with certain duplex 
trim actuators installed. This proposed AD would require repetitively 
inspecting the lateral and longitudinal trim actuator output levers for 
correct torque of the nuts. This proposed AD is prompted by a design 
review that the attachment screws can become lost under certain 
circumstances. The proposed actions are intended to prevent the loss of 
an attachment screw, which could result in movement of the output lever 
in an axial direction, contact of a bolt connecting the control rod to 
an output lever with the actuator housing, and subsequent loss of 
helicopter control.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2013-0182, dated August 12, 
2013, to correct an unsafe condition for Airbus Helicopters Model MBB-
BK 117 C-2 helicopters with a lateral duplex trim actuator, part number 
(P/N) 418-00878-050 or P/N 418-00878-051, or with a longitudinal duplex 
trim actuator, P/N 418-00878-000 or P/N 418-00878-001. EASA advises 
that recent analysis has shown that under unfavorable circumstances, a 
total loss of the trim actuator output lever attachment screw could 
lead to a restriction of the lateral and longitudinal control range. 
According to EASA, without the attachment screw, the output lever can 
move in the axial direction. This condition, if not detected, could 
cause the bolt that connects the control rod to the output lever to 
make contact with actuator housing, possibly resulting in reduced 
control of the helicopter. To prevent this condition, EASA requires an 
initial torque check of the lateral and longitudinal trim actuator 
output level attachment screws, the application of a torque marking, 
and repetitive inspections for correct torque thereafter. The AD's 
requirements are considered an interim solution, pending a terminating 
modification.
    Since the issuance of EASA AD No. 2013-0182, Eurocopter Deutschland 
GmbH has changed its name to Airbus Helicopters Deutschland GmbH.

 FAA's Determination

    These helicopters have been approved by the aviation authority of 
Germany and are approved for operation in the United States. Pursuant 
to our bilateral agreement with Germany, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of the same type design.

Related Service Information

    We reviewed Eurocopter (now Airbus Helicopters) Alert Service 
Bulletin MBB-BK117 C-2-67A-020, Revision 0, dated June 18, 2013 (ASB), 
which advises of a design review that showed that a loss of the 
attachment screw of the trim actuator output lever could restrict the 
lateral and longitudinal control range. The ASB consequently calls for 
an initial torque check and application of torque markings of the self-
locking nuts, and subsequent repetitive inspections to maintain the 
proper torque.

Proposed AD Requirements

    This proposed AD would require, within 300 hours time-in-service 
(TIS) and thereafter at intervals not exceeding 400 hours TIS, 
inspecting the lateral and longitudinal trim actuator output lever 
self-locking nuts for correct torque and applying torque marking. For 
each inspection where the nuts are not torqued to the correct value and 
must be adjusted, the torque marking would be removed and reapplied.

Interim Action

    We consider this AD to be an interim action because Airbus 
Helicopters is currently developing a modification that will address 
the unsafe condition identified in this AD. Once this modification is 
developed, approved and available, we might consider additional 
rulemaking.

Costs of Compliance

    We estimate that this proposed AD would affect 100 helicopters of 
U.S. Registry and that labor costs average $85 per work-hour. Based on 
these estimates, we expect the following costs:
    Applying torque and torque marking to the lateral and longitudinal 
trim actuator output levers would require 1 work-hour for a labor cost 
of $85. No parts would be needed, so the cost for the U.S. fleet would 
total $8,500.
    Visually inspecting for correct torque would require 0.5 work-hour 
for a labor cost of about $43. No parts would be needed, so the total 
cost for the U.S. fleet would be $4,300 per inspection cycle.

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 proposed 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 determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Airbus Helicopters Deutschland GmbH (Previously Eurocopter 
Deutschland GmbH) (Airbus Helicopters) Helicopters: Docket No. FAA-
2014-0578; Directorate Identifier 2013-SW-048-AD.

(a) Applicability

    This AD applies to Airbus Helicopters Model MBB-BK 117 C-2 
helicopters with a lateral duplex trim actuator, part number (P/N) 
418-00878-050 or P/N 418-00878-051, or a longitudinal duplex trim 
actuator, P/N 418-00878-000 or P/N 418-00878-001, installed, 
certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as loss of a trim actuator 
output lever attachment screw. This condition could result in 
movement of the output lever in an axial direction, contact of a 
bolt connecting the control rod to an output lever with the actuator 
housing, and subsequent loss of control of the helicopter.

(c) Comments Due Date

    We must receive comments by October 17, 2014.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) Within 300 hours time-in-service (TIS), apply a torque of 
31.0 inch-pounds (3.5 Nm) to the self-locking nut (nut) on each 
lateral and longitudinal trim actuator output lever and apply a 
torque marking between the nut and the screw.
    (2) Thereafter at intervals not to exceed 400 hours TIS, 
visually inspect each nut on each lateral and longitudinal trim 
actuator output lever to determine whether the torque is at 31.0 
inch-pounds (3.5 Nm). If the torque is not at 31.0 inch-pounds, 
apply a torque of 31.0 inch-pounds (3.5 Nm), remove the previous 
torque marking, and apply a new torque marking between the nut and 
the screw.
    (3) Do not install a lateral duplex trim actuator, part number 
(P/N) 418-00878-050 or P/N 418-00878-051, or a longitudinal duplex 
trim actuator, P/N 418-00878-000 or P/N 418-00878-001, on any 
helicopter unless each nut has been inspected for proper torque in 
accordance with the requirements of this AD.
