SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA) notified us that an unsafe condition may exist on certain Airbus Model A310 airplanes; and Model A300 B4–600, B4–600R, and F4–600R series airplanes and Model C4–605R Variant F airplanes (collectively called A300–600 series airplanes); equipped with a carbon fiber reinforced plastic (CFRP) rudder, any series of part number (P/N) A55471500. The EASA advises that, during maintenance on a Model A300– 600 series airplane, a CFRP rudder was damaged at the trailing edge during a rudder swing test. During damage assessment following this event, unrelated disbonding of the inner skin to the honeycomb core was detected at the lower skin, close to the front spar. Further examination revealed traces of hydraulic fluid in the disbonded area. During an inspection performed as part of the repair process, damage was found on the inner skin starting at the junction between the rudder spar and the lower rib. The EASA also advises that, in a separate incident, disbonding of the rudder inner skin also was detected on a Model A310 airplane undergoing paint removal. Discrepancies of the rudder, if not detected, could result in reduced structural integrity of the rudder. Relevant Service Information Airbus has issued All Operators Telex (AOT) A310–55A2043 and AOT A300– 55A6042, both dated March 2, 2006. The AOTs describe doing the following procedures: • Checking the drainage at the lower edge of the rudder spar for the correct condition. If the aft edge sides of the leading edge butt strap at rib 0 are not clean, the AOTs specify restoring the drainage to the correct condition. • Doing a visual examination of the rudder external surfaces for the presence of contaminant hydraulic fluids. If any contaminant hydraulic fluid is found, the AOTs specify cleaning the rudder external surfaces. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 • Cleaning the inner surface of the rudder panels. • Doing a manual tap test inspection, or an automatic tap test inspection using Woodpecker tool WP632, at the inner side of the rudder panels for any disbond. If any disbond is found using the manual tap test, the AOTs recommend doing a confirmation test using Woodpecker tool WP632 of the disbond. If any disbond is found using Woodpecker tool WP632, the AOTs specify marking the perimeter of any damaged area and documenting the location and size of the finding. • Depending on the number of disbonds found and size of a disbond found, the AOTs specify taking the following corrective actions: Reinspecting the damaged area or doing a permanent repair, within 2,500 flight cycles; doing a permanent repair before further flight, or doing a temporary repair before further flight and then the permanent repair within 1,500 flight cycles; contacting the manufacturer for further instructions before further flight; or extending the inspection area to find all the damage. • Reporting all inspection findings to the manufacturer. The EASA mandated the AOTs and issued airworthiness directive 2006– 0066, dated March 24, 2006, to ensure the continued airworthiness of these airplanes in the European Union. AOT A310–55A2043 refers to Chapter 55–42–11 of the Airbus A310 Structural Repair Manual (SRM) as an additional source of service information for restoring the drainage to the correct condition. AOT A310–55A2043 refers to Chapter 51–78–20 of the A310 SRM as an additional source of service information for cleaning hydraulic fluids from the rudder external surfaces. AOT A310–55A2043 refers to Chapter 55–41–12 of the A310 SRM as an additional source of service information for accomplishing the temporary or permanent repair. AOT A300–55A6042 refers to Chapter 55–42–11 of the Airbus A300–600 SRM as an additional source of service information for restoring the drainage to the correct condition. AOT A300– 55A6042 refers to Chapter 51–78–20 of the A300–600 SRM as an additional source of service information for cleaning hydraulic fluids from the rudder external surfaces. AOT A300– 55A6042 refers to Chapter 55–41–12 of the A300–600 SRM as an additional source of service information for accomplishing the temporary or permanent repair. E:\FR\FM\30MRR1.SGM 30MRR1 Federal Register / Vol. 71, No. 61 / Thursday, March 30, 2006 / Rules and Regulations 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 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 issuing this AD to detect discrepancies of the rudder, which could result in reduced structural integrity of the rudder. This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between the AD and the EASA’s Airworthiness Directive.’’ The AD also requires sending all inspection results to Airbus and the FAA. cprice-sewell on PROD1PC66 with RULES Differences Between the AD and the EASA’s Airworthiness Directive The EASA’s airworthiness directive 2006–0066 requires accomplishing any corrective actions in accordance with AOT A310–55A2043 and AOT A300– 55A6042, as applicable. For the condition where one disbond area per panel with a diameter of less than 130mm is found, the AOTs recommend either reinspecting or doing a permanent repair within 2,500 flight cycles after the inspection. However, we have determined that the safety of the fleet would be better addressed by repair of the damaged area. This AD requires accomplishing either a temporary or permanent repair within 6 months. If the temporary repair is accomplished, this AD further requires accomplishing the permanent repair within 1,500 flight cycles after the temporary repair. The EASA’s airworthiness directive 2006–0066 describes procedures for submitting all inspection results to the manufacturer. This AD also requires that action, as well as submitting all inspection findings to the FAA. The EASA’s airworthiness directive 2006–0066 (in accordance with the referenced Airbus AOTs) requires contacting the manufacturer for instructions on how to repair certain VerDate Aug<31>2005 15:18 Mar 29, 2006 Jkt 208001 conditions. This AD requires repairing those conditions using a method that we approve. Clarification of Inspection Terminology The ‘‘check’’ and ‘‘visual examination’’ specified in the Airbus AOTs are referred to as ‘‘general visual inspections’’ in this AD. We have included the definition for a general visual inspection in a note in this AD. Interim Action This is considered to be interim action. The inspection reports that are required by this AD will enable the manufacturer to obtain better insight into the nature, cause, and extent of the damage, and eventually to develop final action to address the unsafe condition. Once final action has been 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 in less than 30 days. 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 in the ADDRESSES section. Include ‘‘Docket No. FAA–2006–24288; Directorate Identifier 2006–NM–068–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of the AD that might suggest a need to modify it. 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 that 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 may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78), or you may visit https://dms.dot.gov. PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 16031 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. 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 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule; request for comments.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus Model A310 airplanes, Model A300 B4-600 series 
airplanes, Model A300 B4-600R series airplanes, Model A300 F4-600R 
series airplanes, and Model A300 C4-605R Variant F airplanes. This AD 
requires inspections of the rudder for discrepancies and corrective 
action if necessary. This AD also requires reporting all inspection 
results to the airplane manufacturer and the FAA. This AD results from 
two separate findings of inner skin disbonding discovered while 
undergoing unrelated repair and maintenance procedures. We are issuing 
this AD to detect discrepancies of the rudder, which could result in 
reduced structural integrity of the rudder.

DATES: This AD becomes effective March 30, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of March 30, 
2006.
    We must receive comments on this AD by May 30, 2006.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA) notified us that an 
unsafe condition may exist on certain Airbus Model A310 airplanes; and 
Model A300 B4-600, B4-600R, and F4-600R series airplanes and Model C4-
605R Variant F airplanes (collectively called A300-600 series 
airplanes); equipped with a carbon fiber reinforced plastic (CFRP) 
rudder, any series of part number (P/N) A55471500. The EASA advises 
that, during maintenance on a Model A300-600 series airplane, a CFRP 
rudder was damaged at the trailing edge during a rudder swing test. 
During damage assessment following this event, unrelated disbonding of 
the inner skin to the honeycomb core was detected at the lower skin, 
close to the front spar. Further examination revealed traces of 
hydraulic fluid in the disbonded area. During an inspection performed 
as part of the repair process, damage was found on the inner skin 
starting at the junction between the rudder spar and the lower rib. The 
EASA also advises that, in a separate incident, disbonding of the 
rudder inner skin also was detected on a Model A310 airplane undergoing 
paint removal. Discrepancies of the rudder, if not detected, could 
result in reduced structural integrity of the rudder.

Relevant Service Information

    Airbus has issued All Operators Telex (AOT) A310-55A2043 and AOT 
A300-55A6042, both dated March 2, 2006. The AOTs describe doing the 
following procedures:
     Checking the drainage at the lower edge of the rudder spar 
for the correct condition. If the aft edge sides of the leading edge 
butt strap at rib 0 are not clean, the AOTs specify restoring the 
drainage to the correct condition.
     Doing a visual examination of the rudder external surfaces 
for the presence of contaminant hydraulic fluids. If any contaminant 
hydraulic fluid is found, the AOTs specify cleaning the rudder external 
surfaces.
     Cleaning the inner surface of the rudder panels.
     Doing a manual tap test inspection, or an automatic tap 
test inspection using Woodpecker tool WP632, at the inner side of the 
rudder panels for any disbond. If any disbond is found using the manual 
tap test, the AOTs recommend doing a confirmation test using Woodpecker 
tool WP632 of the disbond. If any disbond is found using Woodpecker 
tool WP632, the AOTs specify marking the perimeter of any damaged area 
and documenting the location and size of the finding.
     Depending on the number of disbonds found and size of a 
disbond found, the AOTs specify taking the following corrective 
actions: Reinspecting the damaged area or doing a permanent repair, 
within 2,500 flight cycles; doing a permanent repair before further 
flight, or doing a temporary repair before further flight and then the 
permanent repair within 1,500 flight cycles; contacting the 
manufacturer for further instructions before further flight; or 
extending the inspection area to find all the damage.
     Reporting all inspection findings to the manufacturer.
    The EASA mandated the AOTs and issued airworthiness directive 2006-
0066, dated March 24, 2006, to ensure the continued airworthiness of 
these airplanes in the European Union.
    AOT A310-55A2043 refers to Chapter 55-42-11 of the Airbus A310 
Structural Repair Manual (SRM) as an additional source of service 
information for restoring the drainage to the correct condition. AOT 
A310-55A2043 refers to Chapter 51-78-20 of the A310 SRM as an 
additional source of service information for cleaning hydraulic fluids 
from the rudder external surfaces. AOT A310-55A2043 refers to Chapter 
55-41-12 of the A310 SRM as an additional source of service information 
for accomplishing the temporary or permanent repair.
    AOT A300-55A6042 refers to Chapter 55-42-11 of the Airbus A300-600 
SRM as an additional source of service information for restoring the 
drainage to the correct condition. AOT A300-55A6042 refers to Chapter 
51-78-20 of the A300-600 SRM as an additional source of service 
information for cleaning hydraulic fluids from the rudder external 
surfaces. AOT A300-55A6042 refers to Chapter 55-41-12 of the A300-600 
SRM as an additional source of service information for accomplishing 
the temporary or permanent repair.

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 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 issuing this AD to detect discrepancies of the 
rudder, which could result in reduced structural integrity of the 
rudder. This AD requires accomplishing the actions specified in the 
service information described previously, except as discussed under 
``Differences Between the AD and the EASA's Airworthiness Directive.'' 
The AD also requires sending all inspection results to Airbus and the 
FAA.

Differences Between the AD and the EASA's Airworthiness Directive

    The EASA's airworthiness directive 2006-0066 requires accomplishing 
any corrective actions in accordance with AOT A310-55A2043 and AOT 
A300-55A6042, as applicable. For the condition where one disbond area 
per panel with a diameter of less than 130mm is found, the AOTs 
recommend either reinspecting or doing a permanent repair within 2,500 
flight cycles after the inspection. However, we have determined that 
the safety of the fleet would be better addressed by repair of the 
damaged area. This AD requires accomplishing either a temporary or 
permanent repair within 6 months. If the temporary repair is 
accomplished, this AD further requires accomplishing the permanent 
repair within 1,500 flight cycles after the temporary repair.
    The EASA's airworthiness directive 2006-0066 describes procedures 
for submitting all inspection results to the manufacturer. This AD also 
requires that action, as well as submitting all inspection findings to 
the FAA.
    The EASA's airworthiness directive 2006-0066 (in accordance with 
the referenced Airbus AOTs) requires contacting the manufacturer for 
instructions on how to repair certain conditions. This AD requires 
repairing those conditions using a method that we approve.

Clarification of Inspection Terminology

    The ``check'' and ``visual examination'' specified in the Airbus 
AOTs are referred to as ``general visual inspections'' in this AD. We 
have included the definition for a general visual inspection in a note 
in this AD.

Interim Action

    This is considered to be interim action. The inspection reports 
that are required by this AD will enable the manufacturer to obtain 
better insight into the nature, cause, and extent of the damage, and 
eventually to develop final action to address the unsafe condition. 
Once final action has been 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 in less than 30 days.

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 in the ADDRESSES section. Include ``Docket No. FAA-2006-
24288; Directorate Identifier 2006-NM-068-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of the AD that might 
suggest a need to modify it.
    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 that 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 may review the DOT's complete Privacy Act Statement in the Federal 
Register published on April 11, 2000 (65 FR 19477-78), or you may visit 
https://dms.dot.gov.

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.

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