ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to all BAE Systems (Operations) Limited Model BAe 146 series airplanes and Model Avro 146–RJ series airplanes. The existing AD currently requires revising the maintenance program by incorporating certain airworthiness limitations that require new life limits on certain main landing gear (MLG) components. Since we issued that AD, we have determined that reduced safe life limits on certain nose landing gear (NLG) fittings are necessary. Analysis of these fittings showed the presence of forging indications in the flash line, which might reduce the life limits of these fittings. This proposed AD would require revising the maintenance program to SUMMARY: E:\FR\FM\24JYP1.SGM 24JYP1 44470 Federal Register / Vol. 78, No. 142 / Wednesday, July 24, 2013 / Proposed Rules ehiers on DSK2VPTVN1PROD with PROPOSALS-1 incorporate certain limitations. We are proposing this AD to prevent fatigue cracking of certain structural elements, which could adversely affect the structural integrity of the airplane.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On November 8, 2011, we issued AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), which superseded AD 2010–10–22, Amendment 39–16301 (75 FR 28463, May 21, 2010). AD 2011–24–06 required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), we have determined that reduced safe life limits on certain NLG fittings are necessary. Analysis of these fittings showed the presence of forging indications in the flash line, which might reduce the life limits of these fittings. In addition, the aircraft maintenance manual has been revised to redefine the operating time of the aileron and elevator dampers. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0004, dated January 12, 2012 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: * * * Compliance with [certain chapters of the BAe 146/AVRO 146–RJ Aircraft Maintenance Manual (AMM)] has been identified as a mandatory action for continued airworthiness and EASA AD 2011–0048 was issued to require operators to comply with those instructions. * PO 00000 * Frm 00004 * * Fmt 4702 * Sfmt 4702 Failure to comply with these instructions could result in an unsafe condition. For the reasons described above, this EASA AD retains the requirements of EASA AD 2011–0048 [which corresponds to FAA AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011)], which is superseded, and requires the implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in * * * [certain] sub-chapters of Chapter 05 of the AMM at Revision 105 * * *. The unsafe condition is fatigue cracking of certain structural elements, which could adversely affect the structural integrity of the airplane. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information BAE Systems (Operations) Limited has issued the following service information. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. • Subject 05–10–15, ‘‘Aircraft Equipment Airworthiness Limitations,’’ of Chapter 05, ‘‘Time Limits/ Maintenance Checks,’’ of BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual, Revision 105, dated July 15, 2011. • Subject 05–20–02, ‘‘Airframe Scheduled Maintenance—Landing/ Calendar Life Extended,’’ of Chapter 05, ‘‘Time Limits/Maintenance Checks,’’ of BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual, Revision 105, dated July 15, 2011. • Subject 05–20–05, ‘‘Airframe Scheduled Maintenance—Life Extension Programme Landings Life Extended,’’ of Chapter 05, ‘‘Time Limits/Maintenance Checks,’’ of BAe 146 Series/AVRO 146–RJ Series Aircraft Maintenance Manual, Revision 105, dated July 15, 2011. 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. This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections) and/or Critical Design Configuration E:\FR\FM\24JYP1.SGM 24JYP1 Federal Register / Vol. 78, No. 142 / Wednesday, July 24, 2013 / Proposed Rules Control Limitations (CDCCLs). Compliance with these actions and/or CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) according to paragraph (n) of this AD. The request should include a description of changes to the required actions that will ensure the continued operational safety of the airplane. ehiers on DSK2VPTVN1PROD with PROPOSALS-1 Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 2 products of U.S. registry. The actions that are required by AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), and retained in this proposed AD take about 2 work-hours per product, at an average labor rate of $85 per work hour. Required parts cost about $0 per product. Based on these figures, the estimated cost of the currently required actions is $170 per product. We estimate that it would take about 1 work-hour per product to comply with the new 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 up to $170, or $85 per product. 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. (a) Comments Due Date Regulatory Findings (b) Affected ADs 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. This AD supersedes AD 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011). 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2011–24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011), and adding the following new AD: ■ BAE Systems (Operations) Limited: Docket No. FAA–2013–0627; Directorate Identifier 2012–NM–021–AD. We must receive comments by September 9, 2013. (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. (d) Subject Air Transport Association (ATA) of America Code 05. (e) Reason This AD was prompted by a determination that reduced safe life limits on certain NLG fittings are necessary. We are issuing this AD to prevent fatigue cracking of certain structural elements, which could adversely affect the structural integrity 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) Retained Airworthiness Limitations Revisions (1) This paragraph restates the requirements of paragraph (g) of AD 2011– 24–06, Amendment 39–16870 (76 FR 73477, November 29, 2011).

Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to all BAE Systems (Operations) Limited Model BAe 146 
series airplanes and Model Avro 146-RJ series airplanes. The existing 
AD currently requires revising the maintenance program by incorporating 
certain airworthiness limitations that require new life limits on 
certain main landing gear (MLG) components. Since we issued that AD, we 
have determined that reduced safe life limits on certain nose landing 
gear (NLG) fittings are necessary. Analysis of these fittings showed 
the presence of forging indications in the flash line, which might 
reduce the life limits of these fittings.

This proposed AD would require revising the maintenance program to

[[Page 44470]]

incorporate certain limitations. We are proposing this AD to prevent 
fatigue cracking of certain structural elements, which could adversely 
affect the structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by September 9, 
2013.

Discussion

    On November 8, 2011, we issued AD 2011-24-06, Amendment 39-16870 
(76 FR 73477, November 29, 2011), which superseded AD 2010-10-22, 
Amendment 39-16301 (75 FR 28463, May 21, 2010). AD 2011-24-06 required 
actions intended to address an unsafe condition on the products listed 
above.
    Since we issued AD 2011-24-06, Amendment 39-16870 (76 FR 73477, 
November 29, 2011), we have determined that reduced safe life limits on 
certain NLG fittings are necessary. Analysis of these fittings showed 
the presence of forging indications in the flash line, which might 
reduce the life limits of these fittings. In addition, the aircraft 
maintenance manual has been revised to redefine the operating time of 
the aileron and elevator dampers. The European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Community, has issued EASA Airworthiness Directive 2012-0004, 
dated January 12, 2012 (referred to after this as ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI 
states:

    * * * Compliance with [certain chapters of the BAe 146/AVRO 146-
RJ Aircraft Maintenance Manual (AMM)] has been identified as a 
mandatory action for continued airworthiness and EASA AD 2011-0048 
was issued to require operators to comply with those instructions.
* * * * *
    Failure to comply with these instructions could result in an 
unsafe condition.
    For the reasons described above, this EASA AD retains the 
requirements of EASA AD 2011-0048 [which corresponds to FAA AD 2011-
24-06, Amendment 39-16870 (76 FR 73477, November 29, 2011)], which 
is superseded, and requires the implementation of the new or more 
restrictive maintenance requirements and/or airworthiness 
limitations as specified in * * * [certain] sub-chapters of Chapter 
05 of the AMM at Revision 105 * * *.

The unsafe condition is fatigue cracking of certain structural 
elements, which could adversely affect the structural integrity of the 
airplane. You may obtain further information by examining the MCAI in 
the AD docket.

Relevant Service Information

    BAE Systems (Operations) Limited has issued the following service 
information. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.
     Subject 05-10-15, ``Aircraft Equipment Airworthiness 
Limitations,'' of Chapter 05, ``Time Limits/Maintenance Checks,'' of 
BAe 146 Series/AVRO 146-RJ Series Aircraft Maintenance Manual, Revision

     Subject 05-20-05, ``Airframe Scheduled Maintenance--Life 
Extension Programme Landings Life Extended,'' of Chapter 05, ``Time 
Limits/Maintenance Checks,'' of BAe 146 Series/AVRO 146-RJ Series 
Aircraft Maintenance Manual, Revision 105, dated July 15, 2011.

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.
    This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections) and/or Critical 
Design Configuration

[[Page 44471]]

Control Limitations (CDCCLs). Compliance with these actions and/or 
CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been 
previously modified, altered, or repaired in the areas addressed by 
this AD, the operator may not be able to accomplish the actions 
described in the revisions. In this situation to comply with 14 CFR 
91.403(c), the operator must request approval of an alternative method 
of compliance (AMOC) according to paragraph (n) of this AD. The request 
should include a description of changes to the required actions that 
will ensure the continued operational safety of the airplane.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 2 products of U.S. registry.
    The actions that are required by AD 2011-24-06, Amendment 39-16870 
(76 FR 73477, November 29, 2011), and retained in this proposed AD take 
about 2 work-hours per product, at an average labor rate of $85 per 
work hour. Required parts cost about $0 per product. Based on these 
figures, the estimated cost of the currently required actions is $170 
per product.
    We estimate that it would take about 1 work-hour per product to 
comply with the new 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 up to $170, or $85 
per product.

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.
