ACTION: Final rule; request for comments. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A310 series airplanes; and Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model C4 605R Variant F airplanes (collectively called A300–600). This AD requires one-time general visual, detailed, and tap test inspections for discrepancies in the structural integrity of the rudder and its attachments, and corrective actions if necessary. This AD is prompted by a report that, during cruise, a Model A310 series airplane lost most of its rudder, which was made from composite-fiberreinforced plastic. Investigation revealed that most of the rudder, including the front spar portion above the three servo control actuators was missing. We are issuing this AD to prevent detachment of the rudder from the airplane, which could degrade airplane handling qualities and result in reduced controllability of the airplane. DATES: Effective March 28, 2005. The incorporation by reference of certain publications listed in the AD is approved by the Director of the Federal Register as of March 28, 2005. We must receive comments on this AD by May 27, 2005.

This docket number is FAA–2005– 20748; the directorate identifier for this docket is 2005–NM–063–AD. airplane lost most of its rudder, which was made from composite-fiberreinforced plastic (CFRP). Investigation revealed that most of the rudder, including the front spar portion above the three servo control actuators was missing. The cause of this rudder loss is under investigation. This condition, if not corrected, could result in detachment of the rudder from the airplane, which could degrade airplane handling qualities and result in reduced controllability of the airplane. Examining the Docket Airbus has issued All Operators Telex (AOT) A310A55–2035 (for A310 series airplanes) and AOT A300–600 55A6035 (for A300–600 series airplanes), both dated March 16, 2005. The AOTs describe procedures for one-time general visual, detailed visual, and tap test inspections for damage in the structural integrity of the rudder and its attachments. The inspection procedures include a general visual inspection for damage of the rear spar aft face of the vertical stabilizer, including the trailing edge structure; a detailed visual inspection of the rudder hinge arms and support fittings, the actuator support fittings and the rudder hinge fittings; and a tap test inspection for damage of the rudder side panels of the leading edge from the bottom to top and the forward trailing edge connection from the bottom up to hinge No. 5 around the hoisting points and certain additional areas. The AOTs also specify contacting the manufacturer for certain repair conditions and reporting of inspection results. The DGAC mandated the service information and issued French airworthiness directive UF–2005–048, dated March 18, 2005, to ensure the continued airworthiness of these airplanes in France.

SUPPLEMENTARY INFORMATION: The ´ ´ Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A310 series airplanes; and Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model C4 605R Variant F airplanes (collectively called A300–600). The DGAC advises that, during cruise, a Model A310 series PO 00000 Frm 00025 Fmt 4700 Sfmt 4700 Similar Airplane Models A rudder having the same part number as that installed on Model A310 series airplanes also is installed on Model A300–600 series airplanes. Therefore, the latter airplanes are also subject to the identified unsafe condition and are included in the applicability of the U.S. AD. Further, a rudder having the same part number is installed on early versions of Model A330 and A340 series airplanes. However, we have confirmed that the affected rudder is not installed on any Model A330 series airplanes of U.S. registry. Additionally, there are no Model A340 series airplanes on the U.S. Register. Relevant Service Information E:\FR\FM\28MRR1.SGM 28MRR1 15578 Federal Register / Vol. 70, No. 58 / Monday, March 28, 2005 / Rules and Regulations FAA’s Determination and Requirements of This AD layers and debonding between the outer CFRP layers and the honeycomb core. 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 this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’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 issuing this AD to prevent detachment of the rudder from the airplane, which could degrade airplane handling qualities and result in reduced controllability of the airplane. This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between the AD and the Service Information.’’ The AD also requires sending the inspection results to Airbus, regardless of the findings. Clarification of Certain Sections in Airbus A310 and A300–600 Structural Repair Manuals Although the French airworthiness directive and AOTs do not identify the sections in the SRMs that specify damage limits for the rudder attachments and the rudder side panels, those sections are specified in Note 3 of this AD. Differences Among the AD, French Airworthiness Directive and Service Information Although the French airworthiness directive and the AOTs specify that operators may contact the manufacturer for certain repair conditions, this AD requires operators to repair those conditions per a method approved by either the FAA or the DGAC (or its delegated agent). In light of the type of repair that would be required to address the unsafe condition, and consistent with existing bilateral airworthiness agreements, we have determined that, for this AD, a repair approved by either the FAA or the DGAC (or its delegated agent) would be acceptable for compliance with this AD. The French airworthiness directive and AOTs specify inspecting the rudder attachments and the rudder side panels for damage and reporting findings to the manufacturer, but there is no definition of the type of damage to inspect for or findings to report. This AD requires inspecting for discrepancies in the structural integrity of the rudder and its attachments. For the general visual and detailed inspections, the discrepancies to inspect for and report include corrosion, cracks, abrasion, scratches, and dents. For the tap test, the discrepancies to inspect for and report include delamination in the outer CFRP VerDate jul<14>2003 15:00 Mar 25, 2005 Jkt 205001 Clarification of Inspection Terminology/AOT Number In this AD, the ‘‘detailed visual inspection’’ specified in the AOTs is referred to as a ‘‘detailed inspection.’’ We have included the definition for a detailed inspection in a note in the AD. The French airworthiness directive identifies the AOT number for A310 series airplanes as A310 55A2035; however, the number is transposed in the AOT and identified as A310A55– 2035. This AD will identify the AOT number as A310A55–2035 to adhere to the Office of the Federal Register guidelines for materials incorporated by reference. Interim Action This is considered to be interim action. The inspection report that is required by this AD will enable the FAA, DGAC, and the manufacturer to obtain better insight into the potential unsafe condition, and eventually to develop final action to address it, if necessary. If final action is identified, the FAA may consider further rulemaking. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD; therefore, providing notice and opportunity for public comment before the AD is issued is impracticable, and good cause exists to make this AD effective upon publication in the Federal Register. Comments Invited This AD is a final rule that involves requirements that affect flight safety and was not preceded by notice and an opportunity for public comment; however, we invite you to submit any relevant written data, views, or arguments regarding this AD. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA– 2005–20748; Directorate Identifier 2005–NM–063–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, PO 00000 Frm 00026 Fmt 4700 Sfmt 4700 economic, environmental, and energy aspects of the AD. We will consider all comments received by the closing date and may amend the AD in light of those comments. We will post all comments we receive, without change, to https:// dms.dot.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of our docket Web site, anyone can find and read the comments in any of our dockets, including the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.).

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 have 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 that the 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 E:\FR\FM\28MRR1.SGM 28MRR1 Federal Register / Vol. 70, No. 58 / Monday, March 28, 2005 / Rules and Regulations under the criteria of the Regulatory Flexibility Act.

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

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

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A310 series airplanes; and Model A300 B4-600, B4-
600R, and F4-600R series airplanes, and Model C4 605R Variant F 
airplanes (collectively called A300-600). This AD requires one-time 
general visual, detailed, and tap test inspections for discrepancies in 
the structural integrity of the rudder and its attachments, and 
corrective actions if necessary. This AD is prompted by a report that, 
during cruise, a Model A310 series airplane lost most of its rudder, 
which was made from composite-fiber-reinforced plastic. Investigation 
revealed that most of the rudder, including the front spar portion 
above the three servo control actuators was missing. We are issuing 
this AD to prevent detachment of the rudder from the airplane, which 
could degrade airplane handling qualities and result in reduced 
controllability of the airplane.

DATES: Effective March 28, 2005.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of March 
28, 2005.
    We must receive comments on this AD by May 27, 2005.

SUPPLEMENTARY INFORMATION: The Direction G[eacute]n[eacute]rale de 
l'Aviation Civile (DGAC), which is the airworthiness authority for 
France, notified us that an unsafe condition may exist on certain 
Airbus Model A310 series airplanes; and Model A300 B4-600, B4-600R, and 
F4-600R series airplanes, and Model C4 605R Variant F airplanes 
(collectively called A300-600). The DGAC advises that, during cruise, a 
Model A310 series airplane lost most of its rudder, which was made from 
composite-fiber-reinforced plastic (CFRP). Investigation revealed that 
most of the rudder, including the front spar portion above the three 
servo control actuators was missing. The cause of this rudder loss is 
under investigation. This condition, if not corrected, could result in 
detachment of the rudder from the airplane, which could degrade 
airplane handling qualities and result in reduced controllability of 
the airplane.

Similar Airplane Models

    A rudder having the same part number as that installed on Model 
A310 series airplanes also is installed on Model A300-600 series 
airplanes. Therefore, the latter airplanes are also subject to the 
identified unsafe condition and are included in the applicability of 
the U.S. AD.
    Further, a rudder having the same part number is installed on early 
versions of Model A330 and A340 series airplanes. However, we have 
confirmed that the affected rudder is not installed on any Model A330 
series airplanes of U.S. registry. Additionally, there are no Model 
A340 series airplanes on the U.S. Register.

Relevant Service Information

    Airbus has issued All Operators Telex (AOT) A310A55-2035 (for A310 
series airplanes) and AOT A300-600 55A6035 (for A300-600 series 
airplanes), both dated March 16, 2005. The AOTs describe procedures for 
one-time general visual, detailed visual, and tap test inspections for 
damage in the structural integrity of the rudder and its attachments. 
The inspection procedures include a general visual inspection for 
damage of the rear spar aft face of the vertical stabilizer, including 
the trailing edge structure; a detailed visual inspection of the rudder 
hinge arms and support fittings, the actuator support fittings and the 
rudder hinge fittings; and a tap test inspection for damage of the 
rudder side panels of the leading edge from the bottom to top and the 
forward trailing edge connection from the bottom up to hinge No. 5 
around the hoisting points and certain additional areas. The AOTs also 
specify contacting the manufacturer for certain repair conditions and 
reporting of inspection results. The DGAC mandated the service 
information and issued French airworthiness directive UF-2005-048, 
dated March 18, 2005, to ensure the continued airworthiness of these 
airplanes in France.

FAA's Determination and Requirements of This 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 this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC'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 issuing this AD to prevent detachment of the 
rudder from the airplane, which could degrade airplane handling 
qualities and result in reduced controllability of the airplane. This 
AD requires accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Differences Between the AD and the Service Information.'' The AD also 
requires sending the inspection results to Airbus, regardless of the 
findings.

Differences Among the AD, French Airworthiness Directive and Service 
Information

    Although the French airworthiness directive and the AOTs specify 
that operators may contact the manufacturer for certain repair 
conditions, this AD requires operators to repair those conditions per a 
method approved by either the FAA or the DGAC (or its delegated agent). 
In light of the type of repair that would be required to address the 
unsafe condition, and consistent with existing bilateral airworthiness 
agreements, we have determined that, for this AD, a repair approved by 
either the FAA or the DGAC (or its delegated agent) would be acceptable 
for compliance with this AD.
    The French airworthiness directive and AOTs specify inspecting the 
rudder attachments and the rudder side panels for damage and reporting 
findings to the manufacturer, but there is no definition of the type of 
damage to inspect for or findings to report. This AD requires 
inspecting for discrepancies in the structural integrity of the rudder 
and its attachments. For the general visual and detailed inspections, 
the discrepancies to inspect for and report include corrosion, cracks, 
abrasion, scratches, and dents. For the tap test, the discrepancies to 
inspect for and report include delamination in the outer CFRP layers 
and debonding between the outer CFRP layers and the honeycomb core.

Clarification of Certain Sections in Airbus A310 and A300-600 
Structural Repair Manuals

    Although the French airworthiness directive and AOTs do not 
identify the sections in the SRMs that specify damage limits for the 
rudder attachments and the rudder side panels, those sections are 
specified in Note 3 of this AD.

Clarification of Inspection Terminology/AOT Number

    In this AD, the ``detailed visual inspection'' specified in the 
AOTs is referred to as a ``detailed inspection.'' We have included the 
definition for a detailed inspection in a note in the AD.
    The French airworthiness directive identifies the AOT number for 
A310 series airplanes as A310 55A2035; however, the number is 
transposed in the AOT and identified as A310A55-2035. This AD will 
identify the AOT number as A310A55-2035 to adhere to the Office of the 
Federal Register guidelines for materials incorporated by reference.

Interim Action

    This is considered to be interim action. The inspection report that 
is required by this AD will enable the FAA, DGAC, and the manufacturer 
to obtain better insight into the potential unsafe condition, and 
eventually to develop final action to address it, if necessary. If 
final action is identified, the FAA may consider further rulemaking.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD; therefore, providing notice and opportunity for public comment 
before the AD is issued is impracticable, and good cause exists to make 
this AD effective upon publication in the Federal Register.

Comments Invited

    This AD is a final rule that involves requirements that affect 
flight safety and was not preceded by notice and an opportunity for 
public comment; however, we invite you to submit any relevant written 
data, views, or arguments regarding this AD. Send your comments to an 
address listed under ADDRESSES. Include ``Docket No. FAA-2005-20748; 
Directorate Identifier 2005-NM-063-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD. We will consider 
all comments received by the closing date and may amend the AD in light 
of those comments.
    We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will 
also post a report summarizing each substantive verbal contact with FAA 
personnel concerning this AD. Using the search function of our docket 
Web site, anyone can find and read the comments in any of our dockets, 
including the name of the individual who sent the comment (or signed 
the comment on behalf of an association, business, labor union, etc.). 
You can review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78), or you can visit 
https://dms.dot.gov.

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 have 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 that the 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

[[Page 15579]]

under the criteria of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

of this AD, whichever is first: Perform one-time general visual, 
detailed, and tap test inspections for discrepancies in the 
structural integrity of the rudder and its attachments, in 
accordance with Airbus All Operators Telex (AOT) A310A55-2035 (for 
A310 series airplanes) and Airbus AOT A300-600 55A6035 (for A300-600 
series airplanes), both dated March 16, 2005. For the one-time 
general visual and detailed inspections, discrepancies include 
corrosion, cracks, abrasion, scratches, and dents. For the tap test, 
discrepancies include delamination in the outer CFRP layers and 
debonding between the outer CFRP layers and the honeycomb core.

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
enhance visual access to all exposed surfaces in the inspection 
area. This level of inspection is made under normally available 
lighting conditions such as daylight, hangar lighting, flashlight, 
or droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''


    Note 2: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''
