The service bulletins describe procedures for replacing the attachment landing assemblies of certain blow-down panels of the wing leading edges with new, improved landing assemblies. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The EASA mandated the service information and issued the EASA airworthiness directive 2006– 0048, dated February 16, 2006, to ensure the continued airworthiness of these airplanes in the European Union. Examining the Docket You may examine the AD docket on the Internet at https://dms.dot.gov, or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the DOT street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after the Docket Management System receives them. FAA’s Determination and Requirements of the Proposed AD Discussion The European Aviation Safety Agency (EASA) notified us that an unsafe condition may exist on certain Airbus A330, A340–200, and A340–300 airplanes. The EASA advises that several operators have reported full or partial loss of certain blow-down panels of the wing leading edges during flight. Analysis showed that wing vibration resulted in wear formation of the rivet slots or complete shearing of the attaching rivets of the blow-down panel landings. This condition, if not corrected, could result in damage to the airplane and hazards to persons or property on the ground. Relevant Service Information Airbus has issued Service Bulletins A330–57–3091; and A340–57–4100; These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to FAA Order 8100.14A, ‘‘Interim Procedures for Working with the European Community on Airworthiness Certification and Continued Airworthiness,’’ dated August 12, 2005, the EASA has kept the FAA informed of the situation described above. We have examined the EASA’s findings, evaluated all pertinent information, and determined that we need to issue an AD for products of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance The following table provides the estimated costs for U.S. operators of Model A330 airplanes to comply with the modifications required by this proposed AD. The estimated labor rate is $80 per work hour.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of comment period. AGENCY: SUMMARY: The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to all Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model C4–605R Variant F airplanes (collectively called A300–600 series airplanes); and A310– 200 and –300 series airplanes. The original NPRM would have required a one-time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. The original NPRM resulted from reports of THSAs that have reached their design operational life. This operational life can be extended provided an initial inspection and follow-on repetitive tasks are accomplished. This action revises the original NPRM by revising the initial compliance time. It also allows the component maintenance manual as an alternative repair method. We are proposing this supplemental NPRM to extend the operational life of the THSA to prevent a possible failure of high-time THSAs, which could result in reduced controllability of the airplane. We must receive comments on this supplemental NPRM by June 12, 2006.

Discussion

    The European Aviation Safety Agency (EASA) notified us that an 
unsafe condition may exist on certain Airbus A330, A340-200, and A340-
300 airplanes. The EASA advises that several operators have reported 
full or partial loss of certain blow-down panels of the wing leading 
edges during flight. Analysis showed that wing vibration resulted in 
wear formation of the rivet slots or complete shearing of the attaching 
rivets of the blow-down panel landings. This condition, if not 
corrected, could result in damage to the airplane and hazards to 
persons or property on the ground.

Relevant Service Information

    Airbus has issued Service Bulletins A330-57-3091; and A340-57-4100; 
both dated October 25, 2005. The service bulletins describe procedures 
for replacing the attachment landing assemblies of certain blow-down 
panels of the wing leading edges with new, improved landing assemblies. 
Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition. The EASA mandated 
the service information and issued the EASA airworthiness directive 
2006-0048, dated February 16, 2006, to ensure the continued 
airworthiness of these airplanes in the European Union.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to FAA Order 
8100.14A, ``Interim Procedures for Working with the European Community 
on Airworthiness Certification and Continued Airworthiness,'' dated 
August 12, 2005, the EASA has kept the FAA informed of the situation 
described above. We have examined the EASA's findings, evaluated all 
pertinent information, and determined that we need to issue an AD for 
products of this type design that are certificated for operation in the 
United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
of Model A330 airplanes to comply with the modifications required by 
this proposed AD. The estimated labor rate is $80 per work hour.

    Currently, there are no Model A340-200 or A340-300 airplanes on the 
U.S. Register. However, if an affected Model A340-200 or A340-300 
airplane is imported and placed on the U.S. Register in the future, the 
estimated costs shown in the table above will apply to accomplish the 
required actions of this proposed AD for that airplane.

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,

[[Page 28821]]

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 have 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 that the 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. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
