[Docket No. FAA-2005-21139; Directorate Identifier 2003-NM-196-AD; 
Amendment 39-14193; AD 2005-15-04]

Airworthiness Directives; Bombardier Model CL-600-1A11 (CL-600), 
Model CL-600-2A12 (CL-601), and Model CL-600-2B16 (CL-601-3A, CL-601-
3R, and CL-604) Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier Model CL-600-1A11 (CL-600), Model CL-600-2A12 (CL-
601), and Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604) 
airplanes. This AD requires operators to assign serial numbers or part 
numbers to certain landing gear parts and to establish the number of 
landings on the parts, if necessary. This AD also requires operators to 
revise the Airworthiness Limitations section of the Instructions for 
Continued Airworthiness to reflect the new life limits of the landing 
gear parts. This AD is prompted by reports that landing gear parts that 
have safe-life limits but do not

[[Page 43033]]

have serial numbers or part numbers can be removed from one landing 
gear and re-installed on another, making tracking difficult. We are 
issuing this AD to prevent life-limited landing gear parts from being 
used beyond their safe-life limits, which could lead to collapse of the 
landing gear.

DATES: Effective August 30, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 30, 
2005.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the AD docket on the Internet at http://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 street address stated in the 
ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Bombardier 
Model CL-600-1A11 (CL-600), Model CL-600-2A12 (CL-601), and Model CL-
600-2B16 (CL-601-3A, CL-601-3R, and CL-604) airplanes. That NPRM was 
published in the Federal Register on May 9, 2005 (70 FR 24331). (A 
correction of the rule was published in the Federal Register on May 19, 
2005 (70 FR 28988)). That NPRM proposed to require operators to assign 
serial numbers or part numbers to certain landing gear parts and to 
establish the number of landings on the parts, if necessary. That NPRM 
also proposed to require operators to revise the Airworthiness 
Limitations section of the Instructions for Continued Airworthiness to 
reflect the new life limits of the landing gear parts.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Explanation of Change to Applicability

    We have revised the applicability to reflect the model designations 
as published in the most recent type certificate data sheet.

Conclusion

    We have carefully reviewed the available data and determined that 
air safety and the public interest require adopting the AD with the 
change described previously. We have determined that this change will 
neither increase the economic burden on any operator nor increase the 
scope of the AD.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to assign serial numbers or part numbers to certain landing gear parts 
to comply with this AD.

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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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.

Unsafe Condition

    (d) This AD was prompted by reports that landing gear parts that 
have safe-life limits but do not have serial numbers or part numbers 
can be removed from one landing gear and re-installed on another, 
making tracking difficult. We are issuing this AD to prevent life-
limited landing gear parts from being used beyond their safe-life 
limits, which could lead to collapse of the landing gear.

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.

Add Serial Numbers or Part Numbers

    (f) At the applicable compliance time specified in paragraph 
(f)(1), (f)(2), or (f)(3) of this AD: Add serial numbers and part 
numbers, as applicable, to the parts identified in the service 
bulletins. Do all actions in accordance with the applicable service 
bulletin.
    (1) For parts identified in the Bombardier Service Bulletin 600-
0710, Revision 01, dated December 15, 2003; and Bombardier Service 
Bulletin 601-0546, Revision 01, dated December 15, 2003; as having a 
compliance time of ``five years for the parts listed in Part A': 
Within 60 months after the effective date of this AD.
    (2) For parts identified in Bombardier Service Bulletin 600-
0710, Revision 01, dated December 15, 2003; and Bombardier Service 
Bulletin 601-0546, Revision 01, dated December 15, 2003; as having a 
compliance time of ``ten years for the parts listed in Part B': 
Within 120 months after the effective date of this AD.
    (3) For parts identified in the Bombardier Service Bulletin 604-
32-014, dated May 31, 2002, as having a compliance time of ``no 
later than a calendar time of 8 years': Within 96 months after the 
effective date of this AD.

    Note 1: The Bombardier service bulletins refer to the Messier-
Dowty service bulletins in Table 2 of this AD as additional sources 
of service information for adding part numbers or serial numbers by 
vibro-peening the numbers on main landing gear (MLG) and nose 
landing gear (NLG) components that do not have them; and for 
determining the number of landings for parts without a part number 
or serial number on which the time since new (TSN) and cycles since 
new (CSN) have not been tracked.

Establish the Number of Landings

    (g) At the applicable time specified in paragraph (f) of this 
AD: If a component does not have a serial number and the CSN or TSN 
were not tracked, use the formula in the applicable Messier-Dowty 
service bulletin in Table 2 of this AD to establish the number of 
landings (TSN or CSN), and record the newly calculated TSN or CSN in 
the aircraft log books.

Revise the Airworthiness Limitations Section (ALS)

    (h) Within 30 days after the effective date of this AD, revise 
the ALS of the applicable Instructions for Continued Airworthiness 
to reflect the new life limits of the landing gear parts by 
inserting copies of the Canadair temporary revisions (TR) in Table 3 
of this AD into the ALS of the applicable Canadair Time-Limits/
Maintenance Check Manual. When the contents of the TRs are included 
in the general revisions of the ALS, these TRs may be removed 
provided the relevant information in the ALS is identical to that in 
the TRs.
