AGENCY: 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: SUMMARY: As required by current certification standards, each transport aeroplane has passenger compartment exit signs and emergency lighting strips installed to locate the emergency exits. A number of these strips E:\FR\FM\11OCP1.SGM 11OCP1 Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules and signs are not electrically powered, but are self illuminated by means of a hydrogen isotope, known as Tritium. As this isotope decays over time, these signs will [lose] their brightness. To remain compliant with regulations, Tritium exit signs and lighting strips should be replaced when their brightness has deteriorated below accepted levels. Currently, the Maintenance Review Board (MRB) Maintenance Planning Document does not include an inspection task for signs and strips containing Tritium. This condition, if not detected and corrected, could result in insufficiently bright exit signs and lighting strips, preventing safe evacuation during an emergency, possibly resulting in injury to occupants. srobinson on DSK4SPTVN1PROD with PROPOSALS * * * * * The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.

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 2010–0261, dated December 9, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: As required by current certification standards, each transport aeroplane has passenger compartment exit signs and emergency lighting strips installed to locate the emergency exits. A number of these strips and signs are not electrically powered, but are self illuminated by means of a hydrogen isotope, known as Tritium. As this isotope decays over time, these signs will [lose] their brightness. To remain compliant with regulations, Tritium exit signs and lighting strips should be replaced when their brightness has deteriorated below accepted levels. Currently, the Maintenance Review Board (MRB) Maintenance Planning Document does not include an inspection task for signs and strips containing Tritium. This condition, if not detected and corrected, could result in insufficiently bright exit signs and lighting strips, preventing safe evacuation during an emergency, possibly resulting in injury to occupants. To correct this unsafe condition, EASA issued AD 2010–0200, which required [a PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 62659 detailed visual] inspection of the brightness of all Tritium exit signs and strips and, depending on findings, replacement of insufficiently bright signs and lighting strips. Following the issuance of [EASA] AD 2010–0200, Fokker Services discovered that one Service Bulletin (SB), SBF100–33–023, contained errors in the two groups of aeroplane serial numbers and, consequently, in the related instructions for those aeroplanes in that SB. For the reasons described above, this new [EASA] AD retains the requirements of EASA AD 2010–0200, which is superseded, amends the Applicability and refers to Revision 1 of SBF100–33–023 for the accomplishment instructions. Note: The MRB document will be updated before July 2011 to include an appropriate maintenance task to ensure that the Tritium exit signs and lighting strips meet the minimum brightness requirements. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Fokker Services B.V. has issued Service Bulletins SBF50–33–038, dated July 5, 2010; and SBF100–33–023, Revision 1, dated November 4, 2010. 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. E:\FR\FM\11OCP1.SGM 11OCP1 62660 Federal Register / Vol. 76, No. 196 / Tuesday, October 11, 2011 / Proposed Rules Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 4 products of U.S. registry. We also estimate that it would take about 1 work-hour 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 $85 per product. In addition, we estimate that any necessary follow-on actions would take about 2 work-hours and require parts costing $833, for a cost of $1,003 per product. We have no way of determining the number of products that may need these actions. Authority for This Rulemaking srobinson on DSK4SPTVN1PROD with PROPOSALS 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. 17:42 Oct 07, 2011 Jkt 223001 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. 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. VerDate Mar<15>2010 We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. § 39.13 [Amended] 2.

Subject (d) Air Transport Association (ATA) of America Code 33: Lights. Reason (e) The mandatory continuing airworthiness information (MCAI) states: As required by current certification standards, each transport aeroplane has passenger compartment exit signs and emergency lighting strips installed to locate the emergency exits. A number of these strips and signs are not electrically powered, but are self illuminated by means of a hydrogen isotope, known as Tritium. As this isotope decays over time, these signs will [lose] their brightness. To remain compliant with regulations, Tritium exit signs and lighting strips should be replaced when their brightness has deteriorated below accepted levels. Currently, the Maintenance Review Board (MRB) Maintenance Planning Document does not include an inspection task for signs and strips containing Tritium. This condition, if not detected and corrected, could result in insufficiently bright exit signs and lighting strips, preventing safe evacuation during an emergency, possibly resulting in injury to occupants. * * * * * Compliance (f) You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Actions (g) Within six months after the effective date of this AD, do a detailed visual inspection of the tritium exit signs and emergency lighting strips for required brightness, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF50–33–038, dated July 5, 2010; or SBF100–33–023, Revision 1, dated November 4, 2010; as applicable.

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:

    As required by current certification standards, each transport 
aeroplane has passenger compartment exit signs and emergency 
lighting strips installed to locate the emergency exits. A number of 
these strips

[[Page 62659]]

and signs are not electrically powered, but are self illuminated by 
means of a hydrogen isotope, known as Tritium. As this isotope 
decays over time, these signs will [lose] their brightness.
    To remain compliant with regulations, Tritium exit signs and 
lighting strips should be replaced when their brightness has 
deteriorated below accepted levels. Currently, the Maintenance 
Review Board (MRB) Maintenance Planning Document does not include an 
inspection task for signs and strips containing Tritium.
    This condition, if not detected and corrected, could result in 
insufficiently bright exit signs and lighting strips, preventing 
safe evacuation during an emergency, possibly resulting in injury to 
occupants.
* * * * *
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 November 25, 
2011.

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 2010-0261, dated December 9, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    As required by current certification standards, each transport 
aeroplane has passenger compartment exit signs and emergency 
lighting strips installed to locate the emergency exits. A number of 
these strips and signs are not electrically powered, but are self 
illuminated by means of a hydrogen isotope, known as Tritium. As 
this isotope decays over time, these signs will [lose] their 
brightness.
    To remain compliant with regulations, Tritium exit signs and 
lighting strips should be replaced when their brightness has 
deteriorated below accepted levels. Currently, the Maintenance 
Review Board (MRB) Maintenance Planning Document does not include an 
inspection task for signs and strips containing Tritium.
    This condition, if not detected and corrected, could result in 
insufficiently bright exit signs and lighting strips, preventing 
safe evacuation during an emergency, possibly resulting in injury to 
occupants.
    To correct this unsafe condition, EASA issued AD 2010-0200, 
which required [a detailed visual] inspection of the brightness of 
all Tritium exit signs and strips and, depending on findings, 
replacement of insufficiently bright signs and lighting strips.
    Following the issuance of [EASA] AD 2010-0200, Fokker Services 
discovered that one Service Bulletin (SB), SBF100-33-023, contained 
errors in the two groups of aeroplane serial numbers and, 
consequently, in the related instructions for those aeroplanes in 
that SB.
    For the reasons described above, this new [EASA] AD retains the 
requirements of EASA AD 2010-0200, which is superseded, amends the 
Applicability and refers to Revision 1 of SBF100-33-023 for the 
accomplishment instructions.

    Note: The MRB document will be updated before July 2011 to 
include an appropriate maintenance task to ensure that the Tritium 
exit signs and lighting strips meet the minimum brightness 
requirements.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Fokker Services B.V. has issued Service Bulletins SBF50-33-038, 
dated July 5, 2010; and SBF100-33-023, Revision 1, dated November 4, 
2010. 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.

[[Page 62660]]

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 4 products of U.S. registry. We also estimate that 
it would take about 1 work-hour 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 $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2 work-hours and require parts costing $833, for a cost of 
$1,003 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); 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.

Subject

    (d) Air Transport Association (ATA) of America Code 33: Lights.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    As required by current certification standards, each transport 
aeroplane has passenger compartment exit signs and emergency 
lighting strips installed to locate the emergency exits. A number of 
these strips and signs are not electrically powered, but are self 
illuminated by means of a hydrogen isotope, known as Tritium. As 
this isotope decays over time, these signs will [lose] their 
brightness.
    To remain compliant with regulations, Tritium exit signs and 
lighting strips should be replaced when their brightness has 
deteriorated below accepted levels. Currently, the Maintenance 
Review Board (MRB) Maintenance Planning Document does not include an 
inspection task for signs and strips containing Tritium.
    This condition, if not detected and corrected, could result in 
insufficiently bright exit signs and lighting strips, preventing 
safe evacuation during an emergency, possibly resulting in injury to 
occupants.
* * * * *

Compliance

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

Actions

    (g) Within six months after the effective date of this AD, do a 
detailed visual inspection of the tritium exit signs and emergency 
lighting strips for required brightness, in accordance with the 
Accomplishment Instructions of Fokker Service Bulletin SBF50-33-038, 
dated July 5, 2010; or SBF100-33-023, Revision 1, dated November 4, 
2010; as applicable. If any exit signs or emergency lighting strips 
are insufficiently bright, before further flight, replace the exit 
signs or emergency lighting strips, in accordance with the

[[Page 62661]]

Accomplishment Instructions of Fokker Service Bulletin SBF50-33-038, 
dated July 5, 2010; or SBF100-33-023, Revision 1, dated November 4, 
2010; as applicable. A review of airplane maintenance records is 
acceptable in lieu of the inspection in this paragraph if the 
tritium exit signs and emergency lighting strips can be conclusively 
determined to have been manufactured in 2003 or earlier, from that 
review; however, the replacement in this paragraph must be 
accomplished before further flight after doing the review.

Parts Installation

    (h) As of the effective date of this AD, no person may install 
any tritium exit signs or emergency lighting strips if the 
manufacturing date is seven years or more before the intended 
installation date, or if the manufacturing date cannot be 
determined; unless the tritium exit sign or emergency lighting strip 
has been inspected in accordance with paragraph (g) of this AD, and 
does not need replacement.

Credit for Actions Accomplished in Accordance With Previous Service 
Information

    (i) Inspecting and replacing the tritium exit sign or emergency 
lighting strip in accordance with Fokker Service Bulletin SBF100-33-
023, dated July 5, 2010, before the effective date of this AD is 
acceptable for compliance with the corresponding inspection and 
replacement required by paragraph (g) of this AD.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows: No differences.
