ACTION: Final rule; request for comments. AGENCY: The FAA is adopting a new airworthiness directive (AD) for certain Aerospatiale Model ATR42 and ATR72 airplanes. This AD requires an inspection of the locking bolt of the upper attachment pin of the shock absorber on both main landing gears (MLGs) for the correct installation of the locking bolt and for any missing locking bolt, washer, nut, cotter pin, or compound, and applicable corrective action if necessary. This AD results from a report of migration and subsequent rupture of the attachment pin of the shock absorber of a MLG. We are issuing this AD to prevent failure of a MLG, which could result in significant structural damage to the airplane and possible injury to the occupants. DATES: This AD becomes effective August 23, 2006. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of August 23, 2006.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the airworthiness authority for the European Union, notified us that an unsafe condition may exist on certain Aerospatiale Model ATR42 and ATR72 airplanes. The EASA advises that it has received a report of migration and subsequent rupture of the attachment pin of the shock absorber of a main landing gear (MLG). Investigation revealed that the migration was due to the absence of the locking bolt, which was not installed during manufacturing. This condition, if not corrected, could result in failure of a MLG and consequent structural damage to the airplane and possible injury to the occupants. Relevant Service Information Messier-Dowty has issued Special Inspection Service Bulletin 631–32–190, dated July 12, 2006. The service bulletin describes procedures for a visual inspection of the locking bolt of the upper attachment pin of the shock absorber on both MLGs for the correct installation of the locking bolt and for any missing locking bolt, washer, nut, cotter pin, or compound, and applicable corrective action if necessary. The PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 corrective action includes installing any missing locking bolt, cotter pin, nut, washer, or compound, and ensuring proper installation of the locking bolt. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The EASA mandated the service bulletin and issued emergency airworthiness directive 2006–0216–E, dated July 14, 2006, to ensure the continued airworthiness of these airplanes in the European Union. 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. As described in 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 prevent failure of a MLG, which could result in significant structural damage to the airplane and possible injury to the occupants. This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Difference Between the AD and Service Bulletin.’’ Difference Between the AD and Service Bulletin The service bulletin specifies to contact the manufacturer for instructions on how to repair certain conditions, but this AD requires repairing those conditions using a method that we or the EASA (or its delegated agent) approve. In light of the type of repair that is required to address the unsafe condition, and consistent with existing bilateral airworthiness agreements, we have determined that, for this AD, a repair we or the EASA approve is acceptable for compliance with this AD.

SUPPLEMENTARY INFORMATION:

Discussion

    The European Aviation Safety Agency (EASA), which is the 
airworthiness authority for the European Union, notified us that an 
unsafe condition may exist on certain Aerospatiale Model ATR42 and 
ATR72 airplanes. The EASA advises that it has received a report of 
migration and subsequent rupture of the attachment pin of the shock 
absorber of a main landing gear (MLG). Investigation revealed that the 
migration was due to the absence of the locking bolt, which was not 
installed during manufacturing. This condition, if not corrected, could 
result in failure of a MLG and consequent structural damage to the 
airplane and possible injury to the occupants.

Relevant Service Information

    Messier-Dowty has issued Special Inspection Service Bulletin 631-
32-190, dated July 12, 2006. The service bulletin describes procedures 
for a visual inspection of the locking bolt of the upper attachment pin 
of the shock absorber on both MLGs for the correct installation of the 
locking bolt and for any missing locking bolt, washer, nut, cotter pin, 
or compound, and applicable corrective action if necessary. The 
corrective action includes installing any missing locking bolt, cotter 
pin, nut, washer, or compound, and ensuring proper installation of the 
locking bolt. Accomplishing the actions specified in the service 
information is intended to adequately address the unsafe condition. The 
EASA mandated the service bulletin and issued emergency airworthiness 
directive 2006-0216-E, dated July 14, 2006, to ensure the continued 
airworthiness of these airplanes in the European Union.

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. As described in 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 prevent failure of a MLG, 
which could result in significant structural damage to the airplane and 
possible injury to the occupants. This AD requires accomplishing the 
actions specified in the service information described previously, 
except as discussed under ``Difference Between the AD and Service 
Bulletin.''

Difference Between the AD and Service Bulletin

    The service bulletin specifies to contact the manufacturer for 
instructions on how to repair certain conditions, but this AD requires 
repairing those conditions using a method that we or the EASA (or its 
delegated agent) approve. In light of the type of repair that is 
required to address the unsafe condition, and consistent with existing 
bilateral airworthiness agreements, we have determined that, for this 
AD, a repair we or the EASA approve is acceptable for compliance with 
this AD.

[[Page 44884]]

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-
25537; Directorate Identifier 2006-NM-160-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.

Unsafe Condition

    (d) This AD results from a report of migration and subsequent 
rupture of the attachment pin of the shock absorber of a main 
landing gear (MLG). We are issuing this AD to prevent failure of a 
MLG, which could result in significant structural damage to the 
airplane and possible injury to the occupants.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

General Visual Inspection and Corrective Action

    (f) Within 15 days after the effective date of this AD, do a 
general visual inspection of the locking bolt of the upper 
attachment pin of the shock absorber on both MLGs for the correct 
installation of the locking bolt and for any missing locking bolt, 
washer, nut, cotter pin, or compound; and before further flight, do 
all applicable corrective actions. Do the actions in accordance with 
the Accomplishment Instructions of Messier-Dowty Special Inspection 
Service Bulletin 631-32-190, dated July 12, 2006, except as provided 
by paragraph (g) of this AD.

    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 
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.''

    (h)(1) The Manager, International Branch, ANM-116, has the 
authority to approve AMOCs for this AD, if requested in accordance 
with the procedures found in 14 CFR 39.19.
    (2) Before using any AMOC approved in accordance with Sec.  
39.19 on any airplane to which the AMOC applies, notify the 
appropriate principal inspector in the FAA Flight Standards 
Certificate Holding District Office.
