Airplanes, and Model A340-200 and -300 Series Airplanes

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

ACTION: Final rule; rescission.

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

SUMMARY: This amendment rescinds airworthiness directive (AD) 2009-18-
19 for the products listed above. This AD results from mandatory 
continuing airworthiness information (MCAI) issued by EASA, to rescind 
EASA AD 2010-0083. The MCAI specifies the following:

    It has been assessed that multiple NRV [non-return valve] 
failures in combination with certain trapped fuel cases could 
potentially increase the quantity of unusable fuel on the aeroplane, 
possibly leading to fuel starvation which could result in engines 
in-flight shut down and would constitute an unsafe condition. To 
prevent and detect this condition, EASA issued EASA AD 2010-0083.
    Based on in service experience, mainly on the results of the 
operational test required by

[[Page 33987]]

EASA AD 2010-0083, Airbus has performed a safety analysis on the NRV 
to check if the safety objectives are met.
    This analysis of the Collector Cell motive flow line NRV, taking 
into account all failure scenarios, concludes that the previous non 
compliance can be alleviated. Consequently, no unsafe condition 
exists any more on the affected NRV.
    For the reasons described above, EASA AD 2010-0083 is cancelled.

    This AD rescinds the parallel FAA AD 2009-18-19.

DATES: This AD becomes effective June 10, 2011.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by rescinding an existing AD. That NPRM was published in the 
Federal Register on December 30, 2010 (75 FR 82325) and proposed to 
rescind AD 2009-18-19, Amendment 39-16016 (74 FR 46322, September 9, 
2009). That AD was intended to address an unsafe condition on the 
products listed above.
    Since we issued AD 2009-18-19, EASA issued Airworthiness Directive 
2010-0083-CN, dated September 20, 2010, to cancel EASA AD 2010-0083, 
dated May 3, 2010, for the specified products. EASA AD 2010-0083-CN 
states:

    It has been assessed that multiple NRV [non-return valve] 
failures in combination with certain trapped fuel cases could 
potentially increase the quantity of unusable fuel on the aeroplane, 
possibly leading to fuel starvation which could result in engines 
in-flight shut down and would constitute an unsafe condition. To 
prevent and detect this condition, EASA issued EASA AD 2010-0083.
    Based on in service experience, mainly on the results of the 
operational test required by EASA AD 2010-0083, Airbus has performed 
a safety analysis on the NRV to check if the safety objectives are 
met.
    This analysis of the Collector Cell motive flow line NRV, taking 
into account all failure scenarios, concludes that the previous non 
compliance can be alleviated. Consequently, no unsafe condition 
exists any more on the affected NRV.
    For the reasons described above, EASA AD 2010-0083 is cancelled.

    This AD rescinds the parallel FAA AD 2009-18-19. 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.

Conclusions

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

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and, in general, agree with the 
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.

Regulatory Findings

    We determined that this AD would not have federalism implications 
under Executive Order 13132. This 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://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.
