Download as PDF Federal Register / Vol. 72, No. 111 / Monday, June 11, 2007 / Proposed Rules 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. rmajette on DSK8KYBLC1PROD with MISCELLANEOUS List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, 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. VerDate Mar<15>2010 12:18 Mar 07, 2011 Jkt 223001 § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Airbus: Docket No. FAA–2007–28372; Directorate Identifier 2007–NM–080–AD. Comments Due Date (a) We must receive comments by July 11, 2007. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A300F4–605R and A300F4–622R airplanes; certificated in any category; all serial numbers; on which Airbus Modifications 12088 and 12403 have been embodied during production, or which incorporated Airbus Service Bulletin A300–32–6085 in service, except airplanes on which Airbus Modification 12618 has been embodied during production, or which incorporated Airbus Service Bulletin A300–32–6100 in service. Subject (d) Landing Gear. Reason (e) The mandatory continuing airworthiness information (MCAI) states: Further to cases of parking brake loss at the gate, a pressure switch system had been introduced on some A300–600 aircraft. The aim of this modification was to recover pedals braking authority if parking brake is not efficient, without having to set the parking brake handle to OFF. However, it appears that in case of failure of the pressure switch system, there is the risk of double (normal and alternate) pressurization of the brakes potentially leading to undetected residual braking, which may lead to a loss of performances of the aircraft at Take-Off. This new AD requires accomplishment of a wiring modification that will inhibit the effect of modifications 12088 and 12403. The loss of performance could result in runway overrun or impact with obstacles or terrain during takeoff. Actions and Compliance (f) Within 3 months after the effective date of this AD unless already done: Modify the wiring in the right electronics rack 90VU (volt unit), in accordance with the instructions of Airbus Service Bulletin A300– 32–6100, dated September 18, 2006. FAA AD Differences Note: This AD differs from the MCAI and/ or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Branch, ANM–116, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

SUPPLEMENTARY INFORMATION: rmajette on DSK8KYBLC1PROD with MISCELLANEOUS Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. This streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This proposed AD references the MCAI and related service information that we considered in forming the VerDate Mar<15>2010 12:18 Mar 07, 2011 Jkt 223001 engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles. Comments Invited We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2007–28371; Directorate Identifier 2007–NM–040–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments. We will post all comments we receive, without change, to https:// dms.dot.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 Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2006–13, dated June 6, 2006 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: It has been identified that a roll spoiler cable failure could result in an unacceptable amount of roll spoiler deflection, which could result in reduced controllability of the aircraft. To address this condition, Modsum 8Q100898 has been issued to introduce a spoiler cable disconnect sensing device. This modification has been installed in production on aircraft serial numbers 562 and subsequent. An associated operational check has also been introduced (See Note 1 [of the MCAI]). In addition, Modsum 8Q101443 has been issued to address a potential spoiler cable interference condition on aircraft serial numbers 003 through 123, 125 through 130, 132 through 136, 138 and 139, which do not yet have a spoiler cable tension regulator (Mod[ification] 8/0708) installed. Following incorporation of the spoiler cable disconnect sensing device on several aircraft, it was noted that, in the event of a spoiler cable failure, only the ROLL SPLR INBD HYD caution light will be illuminated until the aircraft speed decreases below 135 kts (knots), at which time the ROLL SPLR OUTBD HYD caution light will also be illuminated. Modsum 8Q101445 has been issued to rework the sensing circuit caution light indication to ensure that it is consistent for spoiler cable disconnects above and below 135 kts. This modification has been installed in production on aircraft serial numbers 600 and subsequent. PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 The corrective action includes installing a spoiler cable disconnect sensing device; correcting a potential spoiler cable interference condition; and reworking the spoiler cable disconnect sensing circuit; as applicable. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier has issued Service Bulletins 8–27–89, Revision ‘E,’ dated January 27, 2005; and 8–27–103, Revision ‘B,’ dated January 24, 2007. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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 166 products of U.S. registry. We also estimate that it would take about 13 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $1,000 per product. Where the service information lists required parts costs that are covered under warranty, we have E:\ERIC\11JNP1.SGM 11JNP1 Federal Register / Vol. 72, No. 111 / Monday, June 11, 2007 / Proposed Rules assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $338,640, or $2,040 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. rmajette on DSK8KYBLC1PROD with MISCELLANEOUS 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.

SUMMARY: The Food and Drug Administration (FDA), after consultation with the Environmental Protection Agency (EPA), is proposing to amend FDA’s regulation on the use of ozone-depleting substances (ODSs) in self-pressurized containers to remove the essential-use designations for oral pressurized metered-dose inhalers (MDIs) containing flunisolide, triamcinolone, metaproterenol, pirbuterol, albuterol and ipratropium in combination, cromolyn, and nedocromil. Under the Clean Air Act, FDA, in consultation with the EPA, is required to determine whether an FDAregulated product that releases an ODS is an essential use of the ODS. Therapeutic alternatives that do not use an ODS are currently marketed and appear to provide all of the important public health benefits of the listed drugs. If the applicable essential-use designations are removed, flunisolide, triamcinolone, metaproterenol, pirbuterol, albuterol and ipratropium in combination, cromolyn, and nedocromil MDIs containing an ODS could not be marketed after a suitable transition period. We will hold an open public meeting on removing these essential-use designations in the near future. DATES: Submit written or electronic comments by August 10, 2007.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

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:

    [A] roll spoiler cable failure could result in an unacceptable 
amount of roll spoiler deflection, which could result in reduced 
controllability of the aircraft.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. This streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This proposed AD references the MCAI and related service 
information that we considered in forming the engineering basis to 
correct the unsafe condition. The proposed AD contains text copied from 
the MCAI and for this reason might not follow our plain language 
principles.

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposed AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2007-
28371; Directorate Identifier 2007-NM-040-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed AD based on those comments.
    We will post all comments we receive, without change, to https://dms.dot.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

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2006-13, dated June 6, 2006 (referred to after this as ``the MCAI''), 
to correct an unsafe condition for the specified products. The MCAI 
states:

    It has been identified that a roll spoiler cable failure could 
result in an unacceptable amount of roll spoiler deflection, which 
could result in reduced controllability of the aircraft. To address 
this condition, Modsum 8Q100898 has been issued to introduce a 
spoiler cable disconnect sensing device. This modification has been 
installed in production on aircraft serial numbers 562 and 
subsequent. An associated operational check has also been introduced 
(See Note 1 [of the MCAI]).
    In addition, Modsum 8Q101443 has been issued to address a 
potential spoiler cable interference condition on aircraft serial 
numbers 003 through 123, 125 through 130, 132 through 136, 138 and 
139, which do not yet have a spoiler cable tension regulator 
(Mod[ification] 8/0708) installed.
    Following incorporation of the spoiler cable disconnect sensing 
device on several aircraft, it was noted that, in the event of a 
spoiler cable failure, only the ROLL SPLR INBD HYD caution light 
will be illuminated until the aircraft speed decreases below 135 kts 
(knots), at which time the ROLL SPLR OUTBD HYD caution light will 
also be illuminated. Modsum 8Q101445 has been issued to rework the 
sensing circuit caution light indication to ensure that it is 
consistent for spoiler cable disconnects above and below 135 kts. 
This modification has been installed in production on aircraft 
serial numbers 600 and subsequent.

The corrective action includes installing a spoiler cable disconnect 
sensing device; correcting a potential spoiler cable interference 
condition; and reworking the spoiler cable disconnect sensing circuit; 
as applicable. You may obtain further information by examining the MCAI 
in the AD docket.

Relevant Service Information

    Bombardier has issued Service Bulletins 8-27-89, Revision `E,' 
dated January 27, 2005; and 8-27-103, Revision `B,' dated January 24, 
2007. The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

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 166 products of U.S. registry. We also estimate that 
it would take about 13 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $1,000 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have

[[Page 32029]]

assumed that there will be no charge for these costs. As we do not 
control warranty coverage for affected parties, some parties may incur 
costs higher than estimated here. Based on these figures, we estimate 
the cost of the proposed AD on U.S. operators to be $338,640, or $2,040 
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); 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

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:

Bombardier, Inc.: Docket No. FAA-2007-28371; Directorate Identifier 
2007-NM-040-AD.

Comments Due Date

    (a) We must receive comments by July 11, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Bombardier Model DHC-8-102, -103, -106, -
201, -202, -301, -311, and -315 airplanes; certificated in any 
category; serial numbers 003 through 599.

Subject

    (d) Flight controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    It has been identified that a roll spoiler cable failure could 
result in an unacceptable amount of roll spoiler deflection, which 
could result in reduced controllability of the aircraft. To address 
this condition, Modsum 8Q100898 has been issued to introduce a 
spoiler cable disconnect sensing device. This modification has been 
installed in production on aircraft serial numbers 562 and 
subsequent. An associated operational check has also been introduced 
(See Note 1 [of the MCAI]).
    In addition, Modsum 8Q101443 has been issued to address a 
potential spoiler cable interference condition on aircraft serial 
numbers 003 through 123, 125 through 130, 132 through 136, 138 and 
139, which do not yet have a spoiler cable tension regulator 
(Mod[ification] 8/0708) installed.
    Following incorporation of the spoiler cable disconnect sensing 
device on several aircraft, it was noted that, in the event of a 
spoiler cable failure, only the ROLL SPLR INBD HYD caution light 
will be illuminated until the aircraft speed decreases below 135 kts 
(knots), at which time the ROLL SPLR OUTBD HYD caution light will 
also be illuminated. Modsum 8Q101445 has been issued to rework the 
sensing circuit caution light indication to ensure that it is 
consistent for spoiler cable disconnects above and below 135 kts. 
This modification has been installed in production on aircraft 
serial numbers 600 and subsequent.

The corrective action includes installing a spoiler cable disconnect 
sensing device; correcting a potential spoiler cable interference 
condition; and reworking the spoiler cable disconnect sensing 
circuit; as applicable.
