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.

PREAMBLE 

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
reference of certain other publications listed in this AD as of August
30, 2005 (70 FR 43032, July 26, 2005).

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 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.
