ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This 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. PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 * * * 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. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective June 25, 2010. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 25, 2010. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue, SE., Washington, DC. FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, International Branch, ANM–116, Transport Airplane Directorate, FAA, 1601 Lind Avenue, SW., Renton, Washington 98057–3356; telephone (425) 227–2125; fax (425) 227–1149. SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on February 25, 2010 (75 FR 8551). That NPRM proposed 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 E:\FR\FM\21MYR1.SGM 21MYR1 Federal Register / Vol. 75, No. 98 / Friday, May 21, 2010 / Rules and Regulations 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. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. cprice-sewell on DSK8KYBLC1PROD with RULES 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 required different actions in this AD from those in the MCAI in order to follow our FAA policies. Any such differences are highlighted in a NOTE within the AD. VerDate Mar<15>2010 12:54 May 20, 2010 Jkt 220001 Costs of Compliance We estimate that this AD will affect 206 products of U.S. registry. We also estimate that it will take about 12 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the 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 AD will not have federalism implications under Executive Order 13132. This AD will 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 AD: 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 AD and placed it in the AD docket. Examining the AD Docket 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 AD docket PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 28481 contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

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. E:\FR\FM\21MYR1.SGM 21MYR1 28482 Federal Register / Vol. 75, No. 98 / Friday, May 21, 2010 / Rules and Regulations 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.

ACTION: Final rule. The FAA is superseding an existing airworthiness directive (AD) for the Dowty Propellers, propeller models listed above. That AD currently requires, for all Dowty Rotol propellers, visual inspections for seizure and for cadmium plating of the blade pitch change operating links and eyebolt fork assemblies. That AD also requires replacement or heat-treatment of the blade pitch change operating links and eyebolt fork assemblies, if necessary. This AD requires the same actions, but cprice-sewell on DSK8KYBLC1PROD with RULES SUMMARY: VerDate Mar<15>2010 12:54 May 20, 2010 Jkt 220001 only for certain propeller models. This AD results from the FAA determining that AD 70–16–02 does not apply to all propellers, since current Dowty propellers are differently designed. We are issuing this AD supersedure to specify the affected propeller models, and to prevent seizure or embrittlement and cracking of the blade pitch change operating links and eyebolt fork assemblies, which could result in reduced controllability of the airplane. DATES: This AD becomes effective June 25, 2010. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of June 25, 2010.

Airworthiness Directives; Airbus Model A300 Series Airplanes; 
Model A300 B4-600, B4-600R, F4-600R Series Airplanes, and Model A300 
C4-605R Variant F Airplanes (Collectively Called A300-600 Series 
Airplanes); and A310 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This 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.
* * * * *
We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective June 25, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 25, 
2010.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on February 25, 2010 
(75 FR 8551). That NPRM proposed 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

[[Page 28481]]

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.

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

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

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 required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 206 products of U.S. registry. 
We also estimate that it will take about 12 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the 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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    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 AD and placed it in the AD docket.

Examining the AD Docket

    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 AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

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

2010-11-03 Airbus: Amendment 39-16308. Docket No. FAA-2010-0172; 
Directorate Identifier 2009-NM-189-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective June 25, 
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.

[[Page 28482]]

    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 of 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.

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,
