We will post all comments we receive, without change, to https:// 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. Examining the AD Docket In the past, some operators have reported difficulties to pressurise the hydraulic reservoirs, due to leakage of the Crissair reservoir air pressurisation check valves. In some cases, the air conditioning system was contaminated with hydraulic mist. The leakage of the check valves was caused by an incorrect spring material. The affected Crissair check valves Part Number (P/N) 2S2794 were then replaced with improved check valves P/N 2S2794–1 in accordance with Airbus Service Information Letter 29– 020. More recently, similar issues were again reported on aeroplanes with Crissair check valves P/N 2S2794–1 installed. The investigations carried out on those check valves have shown that a spring, mounted inside the valve, does not meet the Airbus type design specifications. This situation, if not corrected, can cause hydraulic system functional degradation, possibly resulting in reduced control of the aeroplane when combined with an air duct leak, air conditioning system contamination or, if installed, malfunction of the fire extinguishing system in the Class ‘C’ cargo compartment. For the reasons described above, EASA AD 2008–0166 was issued to require the inspection of the Crissair check valves P/N 2S2794–1, to identify serial numbers (s/n) and the replacement of the affected ones with serviceable units. Later on, further investigation by the vendor Crissair revealed more suspect check valves P/N 2S2794–1. Based on this, it was concluded that EASA AD 2008–0166 did not adequately address the unsafe condition and also did not correctly identify the Functional Item Numbers (FIN) of the various aeroplane installations of the affected valves. Consequently, EASA AD Cancellation Notice No.: 2008–0166–CN was issued on 29 October 2008 to cancel EASA AD 2008–0166. An updated list of suspect check valves with P/N 2S2794–1 has now been issued by Crissair Inc., the manufacturer. Consequently, this EASA AD requires the You may examine the AD docket on the Internet at https:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

The MCAI states: PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 identification of the check valves by s/n and the replacement of the affected ones with serviceable units. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued the following service bulletins: • Airbus Mandatory Service Bulletin A300–29–0124, Revision 02, including Appendices 1, 2, and 3, dated March 10, 2009; • Airbus Mandatory Service Bulletin A300–29–6060, Revision 01, including Appendices 1, 2, and 3, dated March 10, 2009; and • Airbus Mandatory Service Bulletin A310–29–2097, Revision 01, including Appendices 1, 2, and 3, dated March 19, 2009. 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 206 products of U.S. registry. We also estimate that it would E:\FR\FM\25FEP1.SGM 25FEP1 Federal Register / Vol. 75, No. 37 / Thursday, February 25, 2010 / Proposed Rules take about 12 work-hours per product, depending on airplane configuration, 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 $210,120, or $1,020 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 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: Airbus: Docket No. FAA–2010–0172; Directorate Identifier 2009–NM–189–AD. Comments Due Date (a) We must receive comments by April 12, 2010. Affected ADs (b) None. Applicability (c) This AD applies to Airbus Model A300 B2–1A, B2–1C, B2K–3C, B2–203, B4–2C, B4– 103, B4–203, B4–601, B4–603, B4–620, B4– 622, B4–605R, B4–622R, F4–605R, F4–622R, and C4–605R Variant F airplanes; and Model A310–203, –204, –221, –222, –304, –322, –324, and –325 airplanes; certificated in any category, all certified models and all serial numbers on which any Crissair check valve part number 2S2794–1 is installed. Subject (d) Air Transport Association (ATA) of America Code 29: Hydraulic Power; and 26: Fire Protection. Reason (e) The mandatory continuing airworthiness information (MCAI) states: In the past, some operators have reported difficulties to pressurise the hydraulic reservoirs, due to leakage of the Crissair reservoir air pressurization check valves. In some cases, the air conditioning system was contaminated with hydraulic mist. The leakage of the check valves was caused by an incorrect spring material. The affected Crissair check valves Part Number (P/N) 2S2794 were then replaced with improved check valves P/N 2S2794–1 in accordance with Airbus Service Information Letter 29– 020. More recently, similar issues were again reported on aeroplanes with Crissair check valves P/N 2S2794–1 installed. The investigations carried out on those check valves have shown that a spring, mounted inside the valve, does not meet the Airbus type design specifications. This situation, if not corrected, can cause hydraulic system functional degradation, possibly resulting in reduced control of the aeroplane when combined with an air duct leak, air conditioning system contamination or, if installed, malfunction of the fire extinguishing system in the Class ‘C’ cargo compartment. For the reasons described above, EASA [European Aviation Safety Agency] AD 2008– 0166 was issued to require the inspection of the Crissair check valves P/N 2S2794–1, to identify serial numbers (s/n) and the replacement of the affected ones with serviceable units. Later on, further investigation by the vendor Crissair revealed more suspect check valves P/N 2S2794–1. Based on this, it was concluded that EASA AD 2008–0166 did not adequately address the unsafe condition and also did not correctly identify the Functional Item Numbers (FIN) of the various aeroplane installations of the affected valves. Consequently, EASA AD Cancellation Notice No.: 2008–0166–CN was issued on 29 October 2008 to cancel EASA AD 2008–0166. An updated list of suspect check valves with P/N 2S2794–1 has now been issued by Crissair Inc., the manufacturer. Consequently, this EASA AD requires the identification of the check valves by s/n and the replacement of the affected ones with serviceable units. Actions and Compliance (f) Unless already done, do the following actions. (1) At the applicable compliance time specified in Table 1 of this AD: For Crissair check valves, P/N 2S2794–1, identify the serial number using Appendix 1 of the applicable service bulletin identified in Table 2 of this AD, in accordance with the Accomplishment Instructions in the applicable service bulletin identified in Table 2 of this AD. Except as provided by paragraph (f)(2) of this AD, for any valve having a serial number listed in Appendix 1 of the applicable service bulletin identified in Table 2 of this AD, before further flight, install a new or modified check valve in accordance with the applicable service bulletin identified in Table 2 of this AD. sroberts on DSKD5P82C1PROD with PROPOSALS TABLE 1—AFFECTED CHECK VALVE INSTALLATION Affected check valve installation, identified by FIN (functional item number) Compliance time (i) Airplanes having Hydraulic System with FIN 29/1388, FIN 29/2388 and FIN 29/3388.

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Model 747–100, 747–200B, and –200F series airplanes. The existing AD currently requires inspections to detect cracking in the upper row of fasteners holes of the skin lap joints in the fuselage lower lobe, and repair, if necessary. This proposed AD would reduce the maximum interval of the post-modification inspections. This proposed AD results from reports of fatigue cracking on modified airplanes. We are proposing this AD to detect and correct fatigue cracking in the longitudinal lap joints of the fuselage lower lobe, which could lead to the rapid decompression of the airplane and the inability of the structure to carry fail-safe loads.

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:

    In the past, some operators have reported difficulties to 
pressurise the hydraulic reservoirs, due to leakage of the Crissair 
reservoir air pressurisation check valves. * * * The leakage of the 
check valves was caused by an incorrect spring material. The 
affected Crissair check valves * * * were then replaced with 
improved check valves P/N [part number] 2S2794-1 * * *.
    More recently, similar issues were again reported on aeroplanes 
with Crissair check valves P/N 2S2794-1 installed. The 
investigations * * * have shown that a spring, mounted inside the 
valve, does not meet the Airbus type design specifications.
    This situation, if not corrected, can cause hydraulic system 
functional degradation, possibly resulting in reduced control of the 
aeroplane when combined with an air duct leak, air conditioning 
system contamination or, if installed, malfunction of the fire 
extinguishing system in the Class `C' cargo compartment.

* * * * *

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 2009-0171, dated August 5, 2009 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    In the past, some operators have reported difficulties to 
pressurise the hydraulic reservoirs, due to leakage of the Crissair 
reservoir air pressurisation check valves. In some cases, the air 
conditioning system was contaminated with hydraulic mist. The 
leakage of the check valves was caused by an incorrect spring 
material. The affected Crissair check valves Part Number (P/N) 
2S2794 were then replaced with improved check valves P/N 2S2794-1 in 
accordance with Airbus Service Information Letter 29-020.
    More recently, similar issues were again reported on aeroplanes 
with Crissair check valves P/N 2S2794-1 installed. The 
investigations carried out on those check valves have shown that a 
spring, mounted inside the valve, does not meet the Airbus type 
design specifications.
    This situation, if not corrected, can cause hydraulic system 
functional degradation, possibly resulting in reduced control of the 
aeroplane when combined with an air duct leak, air conditioning 
system contamination or, if installed, malfunction of the fire 
extinguishing system in the Class `C' cargo compartment.
    For the reasons described above, EASA AD 2008-0166 was issued to 
require the inspection of the Crissair check valves P/N 2S2794-1, to 
identify serial numbers (s/n) and the replacement of the affected 
ones with serviceable units.
    Later on, further investigation by the vendor Crissair revealed 
more suspect check valves P/N 2S2794-1. Based on this, it was 
concluded that EASA AD 2008-0166 did not adequately address the 
unsafe condition and also did not correctly identify the Functional 
Item Numbers (FIN) of the various aeroplane installations of the 
affected valves. Consequently, EASA AD Cancellation Notice No.: 
2008-0166-CN was issued on 29 October 2008 to cancel EASA AD 2008-
0166.
    An updated list of suspect check valves with P/N 2S2794-1 has 
now been issued by Crissair Inc., the manufacturer. Consequently, 
this EASA AD requires the identification of the check valves by s/n 
and the replacement of the affected ones with serviceable units.

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

Relevant Service Information

    Airbus has issued the following service bulletins:
     Airbus Mandatory Service Bulletin A300-29-0124, Revision 
02, including Appendices 1, 2, and 3, dated March 10, 2009;
     Airbus Mandatory Service Bulletin A300-29-6060, Revision 
01, including Appendices 1, 2, and 3, dated March 10, 2009; and
     Airbus Mandatory Service Bulletin A310-29-2097, Revision 
01, including Appendices 1, 2, and 3, dated March 19, 2009.
    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 206 products of U.S. registry. We also estimate that 
it would

[[Page 8553]]

take about 12 work-hours per product, depending on airplane 
configuration, 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 $210,120, or $1,020 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

    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.


Sec.  39.13  [Amended]

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

Airbus: Docket No. FAA-2010-0172; Directorate Identifier 2009-NM-
189-AD.

Comments Due Date

    (a) We must receive comments by April 12, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A300 B2-1A, B2-1C, B2K-3C, 
B2-203, B4-2C, B4-103, B4-203, B4-601, B4-603, B4-620, B4-622, B4-
605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes; 
and Model A310-203, -204, -221, -222, -304, -322, -324, and -325 
airplanes; certificated in any category, all certified models and 
all serial numbers on which any Crissair check valve part number 
2S2794-1 is installed.

Subject

    (d) Air Transport Association (ATA) of America Code 29: 
Hydraulic Power; and 26: Fire Protection.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    In the past, some operators have reported difficulties to 
pressurise the hydraulic reservoirs, due to leakage of the Crissair 
reservoir air pressurization check valves. In some cases, the air 
conditioning system was contaminated with hydraulic mist. The 
leakage of the check valves was caused by an incorrect spring 
material. The affected Crissair check valves Part Number (P/N) 
2S2794 were then replaced with improved check valves P/N 2S2794-1 in 
accordance with Airbus Service Information Letter 29-020.
    More recently, similar issues were again reported on aeroplanes 
with Crissair check valves P/N 2S2794-1 installed. The 
investigations carried out on those check valves have shown that a 
spring, mounted inside the valve, does not meet the Airbus type 
design specifications.
    This situation, if not corrected, can cause hydraulic system 
functional degradation, possibly resulting in reduced control of the 
aeroplane when combined with an air duct leak, air conditioning 
system contamination or, if installed, malfunction of the fire 
extinguishing system in the Class `C' cargo compartment.
    For the reasons described above, EASA [European Aviation Safety 
Agency] AD 2008-0166 was issued to require the inspection of the 
Crissair check valves P/N 2S2794-1, to identify serial numbers (s/n) 
and the replacement of the affected ones with serviceable units.
    Later on, further investigation by the vendor Crissair revealed 
more suspect check valves P/N 2S2794-1. Based on this, it was 
concluded that EASA AD 2008-0166 did not adequately address the 
unsafe condition and also did not correctly identify the Functional 
Item Numbers (FIN) of the various aeroplane installations of the 
affected valves. Consequently, EASA AD Cancellation Notice No.: 
2008-0166-CN was issued on 29 October 2008 to cancel EASA AD 2008-
0166.
    An updated list of suspect check valves with P/N 2S2794-1 has 
now been issued by Crissair Inc., the manufacturer. Consequently, 
this EASA AD requires the identification of the check valves by s/n 
and the replacement of the affected ones with serviceable units.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) At the applicable compliance time specified in Table 1 of 
this AD: For Crissair check valves, P/N 2S2794-1, identify the 
serial number using Appendix 1 of the applicable service bulletin 
identified in Table 2 of this AD, in accordance with the 
Accomplishment Instructions in the applicable service bulletin 
identified in Table 2 of this AD. Except as provided by paragraph 
(f)(2) of this AD, for any valve having a serial number listed in 
Appendix 1 of the applicable service bulletin identified in Table 2 
of this AD, before further flight, install a new or modified check 
valve in accordance with the applicable service bulletin identified 
in Table 2 of this AD.

    (2) Check valves P/N 2S2794-1 marked with an ``R'' have already 
been modified in accordance with Crissair Service Bulletin 20070407-
29-1 and do not need to be replaced. Check valves with P/N 2S2794 
are not affected and do not need to be replaced.
    (3) As of the effective date of this AD, no person may install 
any Crissair check valve, P/N 2S2794-1, on any airplane unless it 
has a serial number other than those listed in Appendix 1 of the 
applicable service bulletin identified in Table 2 of this AD, or 
unless check valve P/N 2S2794-1 is marked with an ``R.''

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows: Although the MCAI states not to install the part 
identified in paragraph (f)(3) of this AD after accomplishing the 
actions specified in paragraph (f)(1) of this AD, this AD prohibits 
installation of the part as of the effective date of this AD.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
