Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2005-15-04 for 
certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-
601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) 
airplanes. AD 2005-15-04 required operators to assign serial numbers or 
part numbers to certain landing gear parts; establish the number of 
landings on the parts, if necessary; and revise the Airworthiness 
Limitations Section (ALS) of the Instructions for Continued 
Airworthiness (ICA) to reflect the new life limits of the landing gear 
parts. This new AD adds airplanes to the applicability, requires 
operators to assign serial numbers or part numbers to certain 
additional landing gear parts to establish the number of landings on 
the parts if necessary, and requires operators to record in all 
required airplane technical records and manuals the new part numbers, 
serial numbers, and landings assigned to these parts. 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.

DATES: This AD becomes effective September 25, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 25, 
2014.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2005-15-04, Amendment 39-14193 (70 FR 43032, 
July 26, 2005). AD 2005-15-04 applied to certain Bombardier, Inc. Model 
CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, 
CL-601-3R, and CL-604 Variants) airplanes. The NPRM published in the 
Federal Register on December 30, 2013 (78 FR 79329). The NPRM 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. 
The NPRM proposed to add airplanes to the applicability, require 
operators to assign serial numbers or part numbers to certain 
additional landing gear parts to establish the number of landings on 
the parts if necessary, and requires operators to record in all 
required airplane technical records and manuals the new part numbers, 
serial numbers, and landings assigned to these parts. 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.
    Transport Canada Civil Aviation (TCCA), which is the airworthiness 
authority for Canada, has issued Canadian Airworthiness Directives CF-
2003-18R2, dated September 28, 2011; CF-2003-20R1, dated September 28, 
2011; and CF-2003-21R2, dated September 28, 2011 (referred to after 
this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''); to correct an unsafe condition for certain Bombardier, Inc. 
Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-
601-3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI states:

    Certain landing gear parts that are listed in the aeroplane 
model Airworthiness Limitations Section, as safe life items with 
structural life limits, could be rotable and may not have been 
serialized, making tracking difficult. This [Canadian airworthiness] 
directive mandates that such parts be serialized. This [Canadian 
airworthiness] directive also provides the procedure to determine 
the number of landings for those parts where the service history 
cannot be established.
* * * * *
    [T]his [Canadian Airworthiness] directive * * * mandate[s] 
serialization of * * * additional landing gear parts.

This AD also adds airplanes to the applicability. The unsafe condition 
is using life-limited landing gear parts beyond their safe-life limits, 
which could lead to collapse of the landing gear. You may examine the 
MCAI in the

[[Page 49435]]

AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-1065-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 79329, December 30, 
2013) or on the determination of the cost to the public.

``Contacting the Manufacturer'' Paragraph in This AD

    Since late 2006, we have included a standard paragraph titled 
``Airworthy Product'' in all MCAI ADs in which the FAA develops an AD 
based on a foreign authority's AD.
    We have become aware that some operators have misunderstood or 
misinterpreted the Airworthy Product paragraph to allow the owner/
operator to use messages provided by the manufacturer as approval of 
deviations during the accomplishment of an AD-mandated action. The 
Airworthy Product paragraph does not approve messages or other 
information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed the paragraph and retitled 
it ``Contacting the Manufacturer.'' This paragraph now clarifies that 
for any requirement in this AD to obtain corrective actions from a 
manufacturer, the actions must be accomplished using a method approved 
by the FAA, Transport Canada Civil Aviation (TCCA), or Bombardier's 
TCCA Design Approval Organization (DAO).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DAO, the approval must include the DAO-authorized 
signature. The DAO signature indicates that the data and information 
contained in the document are TCCA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer 
that do not contain the DAO-authorized signature approval are not TCCA-
approved, unless TCCA directly approves the manufacturer's message or 
other information.
    This clarification does not remove flexibility previously afforded 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.
    We also have decided not to include a generic reference to either 
the ``delegated agent'' or ``design approval holder (DAH) with State of 
Design Authority design organization approval,'' but instead we have 
provided the specific delegation approval granted by the State of 
Design Authority for the DAH throughout this AD.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD with the changes described 
previously and minor editorial changes. We have determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 79329, December 30, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 79329, December 30, 2013).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Costs of Compliance

    We estimate that this AD affects 419 airplanes of U.S. registry.
    The actions that were required by AD 2005-15-04, Amendment 39-14193 
(70 FR 43032, July 26, 2005), that are retained in this AD take up to 
13 work-hours per product, at an average labor rate of $85 per work 
hour. Based on these figures, the estimated cost of the currently 
required actions is up to $1,105 per product.
    We estimate that it would take about 9 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $320,535, or $765 per product.

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 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 the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), and adding 
the following new AD:

2014-15-13 Bombardier, Inc.: Amendment 39-17915. Docket No. FAA-
2013-1065; Directorate Identifier 2011-NM-230-AD.

(a) Effective Date

    This AD becomes effective September 25, 2014.

(b) Affected ADs

    This AD replaces AD 2005-15-04, Amendment 39-14193 (70 FR 43032, 
July 26, 2005).

(c) Applicability

    This AD applies to Bombardier, Inc. airplanes, certificated in 
any category, as identified in paragraphs (c)(1) through (c)(4) of 
this AD.
    (1) Model CL-600-1A11 (CL-600) airplanes, serial numbers 1004 
through 1085 inclusive.
    (2) Model CL-600-2A12 (CL-601) airplanes, serial numbers 3001 
through 3066 inclusive;
    (3) Model CL-600-2B16 (CL-601-3A and CL-601-3R Variants) 
airplanes, serial numbers 5001 through 5194 inclusive.
    (4) Model CL-600-2B16 (CL-604 Variant) airplanes, serial numbers 
5301 through 5573 inclusive, 5579, and 5595.
    (5) This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections). Compliance 
with these actions is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by this AD, the operator may not be able to 
accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (r) of this AD. The request should include a 
description of changes to the required actions that will ensure the 
continued damage tolerance of the affected structure.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
Gear.

(e) Reason

    This AD was prompted by reports that landing gear parts that 
have safe-life limits but do not have serial numbers (S/Ns) or part 
numbers (P/Ns) 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.

 (f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Requirement To Add S/Ns or P/Ns

    This paragraph restates the actions required by paragraph (f) of 
AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with 
revised affected airplanes. Except for Model CL-600-2B16 airplanes 
having S/Ns 5514 through 5595 inclusive: At the applicable 
compliance time specified in paragraph (g)(1), (g)(2), or (g)(3) of 
this AD, add serial numbers and part numbers, as applicable, to the 
parts identified in the applicable service bulletin specified in 
paragraph (g)(1), (g)(2), or (g)(3) of this AD. Do all actions in 
accordance with the applicable service bulletin specified in 
paragraph (g)(1), (g)(2), or (g)(3) of this AD.
    (1) 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 ``five years for the parts listed in Part A'': 
Within 60 months after August 30, 2005 (the effective date of AD 
2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
    (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 August 30, 2005 (the effective date of AD 
2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
    (3) For parts identified in 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 August 30, 
2005 (the effective date of AD 2005-15-04, Amendment 39-14193 (70 FR 
43032, July 26, 2005)).

    Note 1 to paragraph (g) of this AD:  The Bombardier service 
bulletins identified in paragraphs (g)(1), (g)(2), and (g)(3) of 
this AD refer to the Messier-Dowty service bulletins identified in 
table 1 to paragraph (g) of this AD as additional sources of 
guidance 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.

(h) Retained Requirement--Establishment of the Number of Landings

    This paragraph restates the actions required by paragraph (g) of 
AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with 
revised affected airplanes. Except for Model CL-600-2B16 airplanes 
having S/Ns 5314 through 5595 inclusive: At the applicable time 
specified in paragraph (g) 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 specified in table 
1 to paragraph (g) of this AD to establish the TSN or CSN, and 
record the newly calculated TSN or CSN in the airplane log books.

(i) Retained Requirement To Revise the Airworthiness Limitations 
Section (ALS)

    This paragraph restates the revision required by paragraph (h) 
of AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005),
