SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: SUPPLEMENTARY INFORMATION: During removal of forward and aft wing links, corrosion has been found on the wing links and the wing link attachment bolts in areas that are not readily accessible during the currently required Maintenance Review Board Report (MRBR) zonal inspections or Corrosion Prevention and Control Programme (CPCP) inspections. If left uncorrected, such corrosion could adversely affect the structural integrity of the wing to fuselage joint. * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI. DATES: We must receive comments on this proposed AD by December 1, 2008.

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 2007–0303, dated December 14, 2007 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During removal of forward and aft wing links, corrosion has been found on the wing links and the wing link attachment bolts in areas that are not readily accessible during the currently required Maintenance Review Board Report (MRBR) zonal inspections or Corrosion Prevention and Control Programme (CPCP) inspections. If left uncorrected, such corrosion could adversely affect the structural integrity of the wing to fuselage joint. For this reason, this Airworthiness Directive (AD) requires repetitive detailed visual inspections at the forward and aft wing links and wing link attachment bolts for signs of corrosion, replacement of corroded nuts and bolts and repair of any defects. The MRBR and CPCP will be amended to include the repeat inspections. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information The manufacturer has issued BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53–203, dated May 7, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. E:\FR\FM\31OCP1.SGM 31OCP1 64898 Federal Register / Vol. 73, No. 212 / Friday, October 31, 2008 / 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 We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the proposed AD. ebenthall on PROD1PC60 with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 1 product of U.S. registry. We also estimate that it would take about 20 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $1,600. 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 VerDate Aug<31>2005 13:45 Oct 30, 2008 Jkt 217001 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); and 3. 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 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 adding the following new AD: BAE Systems (Operations) Limited (Formerly British Aerospace Regional Aircraft): Docket No. FAA–2008–1141; Directorate Identifier 2008–NM–025–AD. Comments Due Date (a) We must receive comments by December 1, 2008. Affected ADs (b) None. Applicability (c) This AD applies to BAE Systems (Operations) Limited Model BAe 146–100A, –200A, and –300A series airplanes and Avro PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 146–RJ70A, 146–RJ85A, and 146–RJ100A airplanes, certificated in any category, all models, all serial numbers. Subject (d) Air Transport Association (ATA) of America Code 53: Fuselage. Reason (e) The mandatory continuing airworthiness information (MCAI) states: During removal of forward and aft wing links, corrosion has been found on the wing links and the wing link attachment bolts in areas that are not readily accessible during the currently required Maintenance Review Board Report (MRBR) zonal inspections or Corrosion Prevention and Control Programme (CPCP) inspections. If left uncorrected, such corrosion could adversely affect the structural integrity of the wing to fuselage joint. For this reason, this Airworthiness Directive (AD) requires repetitive detailed visual inspections at the forward and aft wing links and wing link attachment bolts for signs of corrosion, replacement of corroded nuts and bolts and repair of any defects. The MRBR and CPCP will be amended to include the repeat inspections. Actions and Compliance (f) Unless already done, do the following actions: Before accumulating 48 months on the wing link since new, or within 48 months of a wing link being repaired in accordance with a BAE Systems (Operations) Ltd. or EASA approved repair scheme, or within 24 months after the effective date of this AD, whichever occurs latest, and thereafter at intervals not to exceed 48 months, inspect the wing links in accordance with paragraph 2.C. of BAE Systems (Operations) Ltd. Inspection Service Bulletin ISB.53–203, dated May 7, 2007. (1) If any corrosion is found on bolts or nuts, replace the affected bolts and nuts with airworthy parts before next flight in accordance with the service bulletin. (2) If any corrosion to the wing links is found during an inspection, repair before further flight in accordance with a method approved in accordance with EASA (or its delegated agent).

ACTION: Notice of proposed rulemaking (NPRM). ebenthall on PROD1PC60 with PROPOSALS AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain BEECH Model 400, 400A, and MU–300– 10 airplanes. The existing AD currently requires installation of an improved adjustment mechanism on the flightcrew seats and replacement of the existing aluminum seat reinforcement assemblies with steel assemblies. This proposed AD would add airplanes to the applicability of the existing AD. This proposed AD results from reports of incomplete latching of the existing adjustment mechanism and cracked reinforcement assemblies, which could VerDate Aug<31>2005 13:45 Oct 30, 2008 Jkt 217001 result in sudden shifting of a flightcrew seat.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On January 23, 1996, we issued AD 96–03–07, amendment 39–9504 (61 FR 5275, February 12, 1996), for certain BEECH Model 400, 400A, and MU–300– 10 airplanes. That AD requires installation of an improved adjustment mechanism on the flightcrew seats and replacement of the existing aluminum seat reinforcement assemblies with steel assemblies. That AD resulted from reports of incomplete latching of the existing latching adjustment mechanism and cracked reinforcement assemblies. We issued that AD to prevent such shifting of a flightcrew seat, which could impair the flightcrew’s ability to control the airplane. Actions Since Existing AD Was Issued Since we issued AD 96–03–07, we have determined that the same unsafe condition addressed in AD 96–03–07 could exist on Raytheon (Mitsubishi) Model MU–300 airplanes. Therefore, these additional airplanes must be added to the applicability of AD 96–03–07. Relevant Service Information We have reviewed Raytheon Mandatory Service Bulletin SB 25–2536, Revision 2, dated March 2002. The actions described in Revision 2 of the service bulletin are essentially the same as those specified in Beechcraft Service Bulletin 2536, Revision 1, dated April 1995 (we referred to Revision 1 as the appropriate source of service information for doing the actions required by AD 96–03–07). Revision 2 adds airplanes and certain kit numbers. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to develop on other airplanes of the same type design. For this reason, we are proposing this AD, which would supersede AD 96–03– 07 and would retain the requirements of E:\FR\FM\31OCP1.SGM 31OCP1

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 2007-0303, dated December 14, 2007 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During removal of forward and aft wing links, corrosion has been 
found on the wing links and the wing link attachment bolts in areas 
that are not readily accessible during the currently required 
Maintenance Review Board Report (MRBR) zonal inspections or 
Corrosion Prevention and Control Programme (CPCP) inspections. If 
left uncorrected, such corrosion could adversely affect the 
structural integrity of the wing to fuselage joint.
    For this reason, this Airworthiness Directive (AD) requires 
repetitive detailed visual inspections at the forward and aft wing 
links and wing link attachment bolts for signs of corrosion, 
replacement of corroded nuts and bolts and repair of any defects.

    The MRBR and CPCP will be amended to include the repeat 
inspections. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    The manufacturer has issued BAE Systems (Operations) Limited 
Inspection Service Bulletin ISB.53-203, dated May 7, 2007. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.

[[Page 64898]]

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

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 1 product of U.S. registry. We also estimate that it 
would take about 20 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $1,600.

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); and
    3. 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.

2008-NM-025-AD.

Comments Due Date

    (a) We must receive comments by December 1, 2008.

Affected ADs

    (b) None.

Applicability

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

Subject

    (d) Air Transport Association (ATA) of America Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    During removal of forward and aft wing links, corrosion has been 
found on the wing links and the wing link attachment bolts in areas 
that are not readily accessible during the currently required 
Maintenance Review Board Report (MRBR) zonal inspections or 
Corrosion Prevention and Control Programme (CPCP) inspections. If 
left uncorrected, such corrosion could adversely affect the 
structural integrity of the wing to fuselage joint.
    For this reason, this Airworthiness Directive (AD) requires 
repetitive detailed visual inspections at the forward and aft wing 
links and wing link attachment bolts for signs of corrosion, 
replacement of corroded nuts and bolts and repair of any defects.

    The MRBR and CPCP will be amended to include the repeat 
inspections.

Actions and Compliance

    (f) Unless already done, do the following actions: Before 
accumulating 48 months on the wing link since new, or within 48 
months of a wing link being repaired in accordance with a BAE 
Systems (Operations) Ltd. or EASA approved repair scheme, or within 
24 months after the effective date of this AD, whichever occurs 
latest, and thereafter at intervals not to exceed 48 months, inspect 
the wing links in accordance with paragraph 2.C. of BAE Systems 
(Operations) Ltd. Inspection Service Bulletin ISB.53-203, dated May 
7, 2007.
    (1) If any corrosion is found on bolts or nuts, replace the 
affected bolts and nuts with airworthy parts before next flight in 
accordance with the service bulletin.
    (2) If any corrosion to the wing links is found during an 
inspection, repair before further flight in accordance with a method 
approved in accordance with EASA (or its delegated agent).
