The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2012–1040; Directorate Identifier 2012–NM–029–AD] RIN 2120–AA64 Airworthiness Directives; BAE Systems (Operations) Limited Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model BAe 146, and Avro 146–RJ series airplanes. This proposed AD was prompted by a report of loss of the end caps on the anti-icing piccolo tube of the wing leading edge. This proposed AD would require a detailed inspection of the end caps on the anti-icing piccolo tube for lost or loose end caps, and replacing or repairing the end caps if necessary. We are proposing this AD to detect and correct lost and loose end caps on the anti-icing piccolo tube, and ice accretion on the wing leading edge or run-back ice, which could lead to a reduction in the stall margin on approach and loss of controllability of the airplane. DATES: We must receive comments on this proposed AD by November 19, 2012. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0003, dated January 6, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: An operator reported the loss of the wing leading edge anti-icing piccolo tube end caps on two aircraft. This was discovered during routine zonal inspections when the wing tips were removed. The loss of the end cap would result in a reduction in anti-icing efficiency, over the outboard portion of the leading edge of that wing, affecting approximately 25% of the wingspan towards the wing tip. The System Safety Analysis (SSA) classifies the loss of anti-icing of both of the outer wings as hazardous if the loss is not indicated to the crew. The loss of a piccolo tube end cap would not be indicated to the flight crew and, therefore, this reduction in anti-icing capability on one wing must also be classified as hazardous. This condition, if not detected and corrected, could result in ice accretion on the wing leading edge, or run-back ice and could lead to a reduction in the stall margin on approach together with a reduction in roll control authority. For the reasons described above, this [EASA] AD requires a one-off [detailed] inspection [for lost and loose end caps] of the piccolo tube end caps. The results of this inspection will be used to establish a suitable repeat inspection period, which will be introduced through the Maintenance Review Board (MRB) process. The corrective action is replacing or repairing the end caps if necessary. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information BAE Systems (Operations) Limited has issued Inspection Service Bulletin ISB. 30–025, dated April 19, 2011. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. E:\FR\FM\04OCP1.SGM 04OCP1 60652 Federal Register / Vol. 77, No. 193 / Thursday, October 4, 2012 / Proposed Rules FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between This AD and the MCAI or Service Information Although EASA Airworthiness Directive 2012–0003, dated January 6, 2012, and BAE Systems (Operations) Limited Inspection Service Bulletin ISB. 30–025, dated April 19, 2011, specify a reporting requirement, this AD does not require reporting. This difference has been coordinated with EASA. emcdonald on DSK67QTVN1PROD with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 2 products of U.S. registry. We also estimate that it would take about 2 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $340, or $170 per product. In addition, we estimate that any necessary follow-on actions would take about 8 work-hours and require parts costing $140, for a cost of $820 per product. We have no way of determining the number of products that may need these actions. 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 VerDate Mar<15>2010 15:08 Oct 03, 2012 Jkt 229001 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 above, 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; 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 a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A319, A320, and A321 airplanes. The existing AD currently requires installing spacer assemblies at the attachment points of the YZ-latches of the cargo loading system (CLS) in the forward and aft cargo compartments, as applicable. Since we issued that AD, we have emcdonald on DSK67QTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 15:08 Oct 03, 2012 Jkt 229001 received reports that the installation has been applied only on one of the lower deck cargo holds, instead of on both forward and aft cargo holds, and that some airplanes could have installed the affected YZ-latches through the instructions of the cargo conversion manual. This proposed AD would require modifying the attachment points of fixed YZ-latches of the CLS lower deck cargo holds on those airplanes on which one or both lower deck cargo holds have not been modified. We are proposing this AD to prevent failure of the attachment points of the YZ-latches, which could result in unrestrained cargo causing damage to the fire protection system, hydraulic system, electrical wiring, or other equipment located in the forward and aft cargo compartments. This damage could adversely affect the continued safe flight of the airplane. DATES: We must receive comments on this proposed AD by November 19, 2012.

Discussion On February 22, 2007, we issued AD 2007–05–13, Amendment 39–14974 (72 FR 10348, March 8, 2007). That AD required actions intended to address an unsafe condition on certain Airbus Model A319, A320, and A321 series airplanes. Since we issued AD 2007–05–13, Amendment 39–14974 (72 FR 10348, March 8, 2007), we have determined that additional airplanes are affected by the unsafe condition. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011–0077, dated May 5, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Investigation has revealed that the installed Tie Down Points of YZ latches on the Cargo Loading System (CLS) of Airbus A319, A320 and A321 aeroplanes do not withstand the maximum loads in accordance with the certification requirements (CS 25.787 ‘‘Stowage compartments’’). In case of failure of Tie Down Points, unrestrained cargo parts could cause damage in the Forward (FWD) and AFT lower deck E:\FR\FM\04OCP1.SGM 04OCP1

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
BAE Systems (Operations) Limited Model BAe 146, and Avro 146-RJ series 
airplanes. This proposed AD was prompted by a report of loss of the end 
caps on the anti-icing piccolo tube of the wing leading edge. This 
proposed AD would require a detailed inspection of the end caps on the 
anti-icing piccolo tube for lost or loose end caps, and replacing or 
repairing the end caps if necessary. We are proposing this AD to detect 
and correct lost and loose end caps on the anti-icing piccolo tube, and 
ice accretion on the wing leading edge or run-back ice, which could 
lead to a reduction in the stall margin on approach and loss of 
controllability of the airplane.

DATES: We must receive comments on this proposed AD by November 19, 
2012.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0003, dated January 6, 2012 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    An operator reported the loss of the wing leading edge anti-
icing piccolo tube end caps on two aircraft. This was discovered 
during routine zonal inspections when the wing tips were removed. 
The loss of the end cap would result in a reduction in anti-icing 
efficiency, over the outboard portion of the leading edge of that 
wing, affecting approximately 25% of the wingspan towards the wing 
tip.
    The System Safety Analysis (SSA) classifies the loss of anti-
icing of both of the outer wings as hazardous if the loss is not 
indicated to the crew. The loss of a piccolo tube end cap would not 
be indicated to the flight crew and, therefore, this reduction in 
anti-icing capability on one wing must also be classified as 
hazardous.
    This condition, if not detected and corrected, could result in 
ice accretion on the wing leading edge, or run-back ice and could 
lead to a reduction in the stall margin on approach together with a 
reduction in roll control authority.
    For the reasons described above, this [EASA] AD requires a one-
off [detailed] inspection [for lost and loose end caps] of the 
piccolo tube end caps. The results of this inspection will be used 
to establish a suitable repeat inspection period, which will be 
introduced through the Maintenance Review Board (MRB) process.

    The corrective action is replacing or repairing the end caps if 
necessary. You may obtain further information by examining the MCAI in 
the AD docket.

Relevant Service Information

    BAE Systems (Operations) Limited has issued Inspection Service 
Bulletin ISB. 30-025, dated April 19, 2011. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI.

[[Page 60652]]

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This AD and the MCAI or Service Information

    Although EASA Airworthiness Directive 2012-0003, dated January 6, 
2012, and BAE Systems (Operations) Limited Inspection Service Bulletin 
ISB. 30-025, dated April 19, 2011, specify a reporting requirement, 
this AD does not require reporting. This difference has been 
coordinated with EASA.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 2 products of U.S. registry. We also estimate that 
it would take about 2 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $340, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 8 work-hours and require parts costing $140, for a cost of 
$820 per product. We have no way of determining the number of products 
that may need these actions.

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

    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 above, 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; 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 a regulatory 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

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

    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]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

>BAE Systems (Operations) Limited: Docket No. FAA-2012-1040; 
Directorate Identifier 2012-NM-029-AD.

(a) Comments Due Date

    We must receive comments by November 19, 2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all BAE Systems (Operations) Limited Model 
BAe 146-100A, -200A, and -300A airplanes; and Model Avro 146-RJ70A, 
146-RJ85A, and 146-RJ100A airplanes; certificated in any category; 
all serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 30, Ice and rain 
protection.

(e) Reason

    This AD was prompted by a report of loss of the end caps on the 
anti-icing piccolo tube of the wing leading edge. We are issuing 
this AD to detect and correct lost and loose end caps on the anti-
icing piccolo tube, and ice accretion on the wing leading edge or 
run-back ice, which could lead to a reduction in the stall margin on 
approach and loss of controllability of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Inspection

    Within 12 months after the effective date of this AD: Do a 
detailed inspection of the end caps on the anti-icing piccolo tube 
for lost and loose end caps, in accordance the Accomplishment 
Instructions of BAE Systems (Operations) Limited Inspection Service 
Bulletin ISB. 30-025, dated April 19, 2011.

(h) Corrective Action

    If, during the detailed inspection required by paragraph (g) of 
this AD, a lost or loose end cap of the anti-icing piccolo tube is 
found: Before next flight, replace the end cap, in accordance the 
Accomplishment Instructions of BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB. 30-025, dated April 19, 2011, or 
repair in accordance with a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
or the European Aviation Safety Agency (EASA) (or its delegated 
agent).

(i) No Reporting Requirement

    EASA Airworthiness Directive 2012-0003, dated January 6, 2012, 
specifies a reporting requirement; this AD does not require 
reporting.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
