AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus transport category airplanes, identified above. This AD
requires an inspection to determine if a certain lower pin (p-pin) of
the retraction actuator of the main landing gear (MLG) is installed. If
the affected p-pin is installed, this AD requires a one-time inspection
of the p-pin for correct grease hole position and cracking; repetitive
daily inspections for pin migration; and eventual replacement of all p-
pins with new p-pins. For any p-pin that is cracked or shows pin
migration, this AD requires immediate replacement with a new p-pin.
Replacing the p-pin with one that is correctly manufactured (i.e., that
has the correct grease hole position) is terminating action for the
repetitive inspections. This AD results from a report that a cracked p-
pin was found when the MLG was removed for overhaul. We are issuing
this AD to prevent failure of the p-pin, which could result in
degradation of the MLG structural integrity and possible hazardous
landing.
DATES: Effective October 14, 2005.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of October 14,
2005.
We must receive comments on this AD by November 28, 2005.

Discussion
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 Airbus Model A330-200 and -300 series
airplanes; and Model A340-200 and -300 series airplanes; equipped with
main landing gear (MLG) retraction actuator lower pin(s) (p-pins)
having part number (P/N) 201275602. The DGAC advises that when the MLG
was removed for overhaul, a p-pin, which connects the lower end of the
retraction actuator to the main fitting, was found to be cracked.
Investigators concluded that the crack initiated from the center grease
hole of the p-pin, and that the center grease hole was machined in an
incorrect position, 90 degrees from its normal position. The two end
holes of the p-pin were also found to be machined 90 degrees from the
original design. Failure of the p-pin could lead to an undamped
extension of the MLG, causing high loads throughout the entire MLG and
damage to the gear structure, the side stay assembly, and the bogie
beam. This condition, if not corrected, could result in degradation of
the MLG structural integrity and a possible hazardous landing.
Relevant Service Information
Airbus has issued All Operators Telex (AOT) A330-32A3181, dated May
27, 2004 (for Model A330-200, and -300 series airplanes); and AOT A340-
32A4224, dated May 27, 2004 (for Model A340-200 and -300 series
airplanes). The AOTs describe procedures for determining if the
affected p-pins are installed. For all affected p-pins, including
spares, the AOTs describe procedures for a one-time inspection to
determine the position of the grease holes and for cracking of the p-
pin. If the position of any grease hole is not correct, the AOTs
specify that it should be replaced within 800 flight hours. Until this
replacement is accomplished, the AOTs give procedures for daily
external visual checks for pin migration. If pin migration is found, or
if any crack is found during the one-time inspection, the AOTs specify
that the pin should be replaced before further flight. The AOTs also
recommend that operators complete a reporting form and send it to the
part vendor. Accomplishing the actions specified in the service
information is intended to adequately address the unsafe condition. The
DGAC mandated the service information and issued French airworthiness
directive F-2004-084, dated June 23, 2004, to ensure the continued
airworthiness of these airplanes in France.
The AOTs refer to Messier-Dowty Service Bulletin A33/34-32-229,
Revision 1, including Appendixes A and B, dated June 4, 2004, as an
additional source of service information for inspecting the p-pins and
for replacing them with a new pin having the same P/N or a new pin
having a new P/N.
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 failure of the p-pin,
which could result in degradation of the MLG structural integrity and
possible hazardous landing. This AD requires accomplishing the actions
specified in the service information described previously.
Difference Between This AD and the French Airworthiness Directive
Although the French airworthiness directive specifies that
operators report inspection results to the parts manufacturer, this AD
does not include that requirement.
[[Page 56820]]
Clarification of Inspection Language
The French airworthiness directive and the AOTs specify that
operators should do a ``visual inspection'' or ``one-time inspection''
to detect incorrectly manufactured p-pins. In this AD we refer to this
inspection as a ``detailed inspection.'' Note 2 of this AD defines this
inspection.
The French airworthiness directive and the AOTs specify that
operators should do an ``external visual inspection'' or ``external
visual check'' of the p-pin for pin migration. In this AD we refer to
this inspection as a ``general visual inspection.'' Note 3 of this AD
defines this inspection.
Costs of Compliance
None of the airplanes affected by this action are on the U.S.
Register. All airplanes affected by this AD are currently operated by
non-U.S. operators under foreign registry; therefore, they are not
directly affected by this AD action. However, we consider this AD
necessary to ensure that the unsafe condition is addressed if any
affected airplane is imported and placed on the U.S. Register in the
future.
The following table provides the estimated costs to comply with
this AD for any affected airplane that might be imported and placed on
the U.S. Register in the future.
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Work Average labor Cost per
Action hours rate per hour Parts cost airplane
----------------------------------------------------------------------------------------------------------------
Inspection to determine P/N of p-pins.... 1 $65 None........................ $65
Detailed inspection for incorrectly 1 65 None........................ 65
manufactured p-pins.
----------------------------------------------------------------------------------------------------------------
FAA's Determination of the Effective Date
No airplane affected by this AD is currently on the U.S. Register.
Therefore, providing notice and opportunity for public comment is
unnecessary before this AD is issued, and this AD may be made effective
in less than 30 days after it is published in the Federal Register.
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.

date of this AD, whichever
[[Page 56821]]
occurs earlier: Inspect the p-pins of the retraction actuator of the
MLG to determine whether part number (P/N) 201275602 is installed.
Do the inspection in accordance with the applicable AOT. A review of
airplane maintenance records is acceptable in lieu of this
inspection if the P/N of the p-pin can be conclusively determined
from that review. If a p-pin with a part number that is different
than P/N 201275602 is installed, or if any P/N 201275602 p-pin has a
batch number or serial number identified in Appendix A of Messier-
Dowty Service Bulletin A33/34-32-229, Revision 1, dated June 4,
2004, no further action is required by this AD, except as provided
by paragraph (l) of this AD.
Inspection for Cracking and Grease Hole Position
(h) If the inspection required by paragraph (g) of this AD shows
that an affected P/N 201275602 is installed, before further flight
after determining the P/N in accordance with paragraph (g) of this
AD: Do a detailed inspection for cracking of the p-pin and position
of the grease holes, in accordance with the applicable AOT. If any
incorrect grease hole position is found or if any crack is found, do
the applicable actions in paragraphs (i) and (j) of this AD at the
times specified in those paragraphs. If all grease hole positions
are correct and no cracking is found, no further action is required
by this paragraph.

(i) If the inspection required by paragraph (h) of this AD shows
that a p-pin has any incorrect grease hole position, but no
cracking: Do the actions in paragraph (i)(1) and (i)(2) of this AD.
Do all actions in accordance with the applicable AOT.
(1) Within 24 hours after the inspection required by paragraph
(h) of this AD: Do a general visual inspection of the p-pin for pin
migration, in accordance with the applicable AOT. Repeat the
inspection at intervals not to exceed 24 hours until the replacement
required by paragraph (i)(2) or (j) of this AD is accomplished.
(2) Except as required by paragraph (j) of this AD, within 800
flight hours after doing the inspection required by paragraph (h) of
this AD: Replace the p-pin with a new p-pin of the same P/N
201275602 with correctly positioned grease holes, or with a new p-
pin having new P/N 201478612, in accordance with the applicable AOT.
Note 3: 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
ensure visual access to all 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.''
(j) If any inspection required by paragraphs (h) and (i) of this
AD shows a crack or pin migration, before further flight: Replace
the p-pin with a new p-pin of the same P/N 201275602 with correctly
positioned grease holes, or with a new p-pin having new P/N
201478612. Do all actions in accordance with the applicable AOT.
No Reporting Required
(k) Although the AOTs reference a reporting requirement in
paragraph 4.3, ``Material--Tooling,'' that reporting is not required
by this AD.
Parts Installation
(l) As of the effective date of this AD, no person may install,
on any airplane, a p-pin, P/N 201275602, unless it has been
inspected and any applicable additional inspections corrective
actions have been done in accordance with this AD.
