39-19629; AD 2019-08-08]
RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2010-14-05,
which applied to certain Bombardier, Inc., Model CL-600-1A11 (600), CL-
600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants)
airplanes. AD 2010-14-05 required inspection for the part numbers of
the system and brake accumulators, and repetitive replacement of
affected accumulators. This AD adds requirements for relocating the
accumulators and revising the existing maintenance or inspection
program to incorporate new or more restrictive airworthiness
limitations. This AD also adds optional terminating action for certain
airplanes. This AD was prompted by reports of on-ground hydraulic
accumulator screw cap or end cap failure that resulted in the loss of
the associated hydraulic system and high-energy impact damage to
adjacent systems and structure. We are issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective June 27, 2019.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of June 27,
2019.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2010-14-05, Amendment 39-16350 (75 FR 37994,
July 1, 2010) (``AD 2010-14-05''). AD 2010-14-05 applied to certain
Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-
600-2B16 (601-3A, 601-3R, and 604 Variants) airplanes. The NPRM
published in the Federal Register on September 14, 2018 (83 FR 46670).
The NPRM was prompted by reports of on-ground hydraulic accumulator
screw cap or end cap failure that resulted in the loss of the
associated hydraulic system and high-energy impact damage to adjacent
systems and structure. The NPRM proposed to continue to require
inspection for the part numbers of the system and brake accumulators,
and repetitive replacement of affected accumulators. The NPRM also
proposed to require relocating the accumulators and revising the
existing maintenance or inspection program to incorporate new or more
restrictive airworthiness limitations. The NPRM also proposed to add
optional terminating action for certain airplanes. We are issuing this
AD to address failure of one of the brake accumulator screw caps/end
caps, which could result in impact damage causing loss of both
hydraulic systems No. 2 and No. 3, and the consequent loss of both
braking and nose wheel steering, the potential for a runway excursion,
and damage to the airplane.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2009-39R1, dated
October 13, 2017 (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 (600), CL-
600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R, and 604 Variants)
airplanes. The MCAI states:
Seven cases of on-ground hydraulic accumulator screw cap or end
cap failure have been experienced on CL-600-2B19 (CRJ) aircraft,
resulting in loss of the associated hydraulic system and high-energy
impact damage to adjacent systems and structure. The lowest number
of flight cycles accumulated at the time of failure, to date, has
been 6991 flight cycles.
Although there have been no failures to date on any CL-600-1A11,
CL-600-2A12 or CL-600-2B16 aircraft, the same accumulators as those
installed on the CL-600-2B19, Part Numbers (P/N) 08-60163-002 and
08-60164-002 are installed on some of the aircraft listed in the
Applicability section of this directive.
Notes:
1. Earlier accumulators, P/Ns 2770571-102, 2770571-103, 2770571-
104 and 2770571-105, were installed in production on the following
aircraft: CL-600-1A11 [all Serial Numbers (S/Ns)], CL-600-2A12 (all
S/Ns) and CL-600-2B16 (S/Ns 5001 through 5194 and 5301 through 5524
only). These accumulators do not require inspection or replacement.
However, if any of the accumulators with the above P/Ns have been
replaced in-service by P/Ns 08-60163-002 and 08-60164-002, these
latter accumulators require replacement.
[[Page 23704]]
2. Prior to issuance of [Canadian] AD CF-2009-39, the only
accumulators ever installed in production on CL-600-2B16 aircraft,
S/Ns 5525 through 5665 and 5701 through 5908, are P/Ns 08-60163-002
and 08-60164-002; these accumulators require replacement.
3. After issuance of [Canadian] AD CF-2009-39 [which corresponds
to FAA AD 2010-14-05], accumulators with P/Ns specified in Note 2,
above, began to feature various S/N suffixes. Only accumulators with
S/N suffix ``TNAE'' do not require replacement, but they are subject
to other mandatory actions detailed in this AD.
4. Stainless steel accumulators P/Ns 601R75139-3 (11094-4) and
601R75139-1 (11093-4) were installed in production on CL-600-2B16
aircraft, S/Ns 5909 and subsequent. These accumulators do not
require replacement, but they are subjected to other mandatory
actions detailed in this AD.
A detailed analysis of the systems and structure in the
potential line of trajectory of a failed screw cap/end cap for each
accumulator, P/Ns 08-60163-002 and 08-60164-002, has been conducted.
On the Challengers, it has been identified that the worst case
scenario would be a failure of system No. 1, 2 or 3 accumulator
screw caps/end caps (depending on the model), resulting in a
potential uncontrolled fire in a non-designated fire zone.
The original version of this [Canadian] AD gave instructions to
perform identification and records checks, where applicable, and
replace accumulators, P/Ns 08-60163-002 and 08-60164-002 within the
time compliance specified.

Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment.
Request To Refer to Latest Service Information
Bombardier requested that we refer to the latest version of the
service information: Bombardier Challenger CL-605 Time Limits/
Maintenance Checks (TLMC), Revision 19, dated May 29, 2018.
We agree to refer to the latest service information. The specific
tasks required by paragraph (j) of this AD have not changed in the
latest available service information. The current version of the
Bombardier Challenger CL-605 Time Limits/Maintenance Checks, Part 2,
Airworthiness Limitations, is Revision 20, dated November 19, 2018. We
have changed all references accordingly in this final rule, with credit
provided in paragraph (l)(6) of this AD for the prior accomplishment of
Revision 18, dated December 4, 2017, and Revision 19, dated May 29,
2018.
The current version of the Bombardier Challenger CL-604 Time
Limits/Maintenance Checks, Part 2, Airworthiness Limitations, is
Revision 31, dated November 19, 2018. We have changed all references
accordingly in this final rule, with credit provided in paragraph
(l)(5) of this AD for the prior accomplishment of Revision 30, dated
December 4, 2017.
Request for Minor Editorial Changes
Bombardier requested several minor changes to the NPRM, including
correcting a typographical error in an email address, updating the
address for Bombardier, updating the airplane identity to match the
models and variants as listed on the current type certificate data
sheet (TCDS), and clarifying part numbers and service bulletin numbers.
We agree and have revised this AD accordingly.
Request To Revise Model Callout
Bombardier asked us to change ``604 Variants'' to ``604 Variant''
in the SUMMARY and ``Actions Since AD 2010-14-05 Was Issued'' section
of the NPRM.
We disagree with this request because there are multiple variants
for the CL-600-2B16 airplanes. We have not changed this final rule
regarding this issue.
Comment Regarding TLMC Revision Status
Bombardier noted that the TLMC revisions listed in figure 2 to
paragraph (j) of this AD are the latest versions published on the
customer website and not when the tasks were introduced. No change was
requested or made.
Request To Clarify Applicability
Bombardier requested that we revise the applicability for Model CL-
600-2B16 airplanes in paragraph (c)(5) of the proposed AD by changing
serial numbers ``5701 and subsequent'' to ``5701 through 5988.''
We agree to make this change. We have determined that production
for this model ended with serial number 5988; therefore, there is no
change to the affected airplanes in this AD.
Request To Revise Certain Airplanes Subject to Accumulator Relocation
Bombardier requested that we revise the affected airplanes
identified in paragraph (i)(4) of the proposed AD, from ``S/Ns 5701 and
subsequent'' to ``S/Ns 5701 to 5982.''
We agree with the request. We have determined that accumulators on
airplanes with serial numbers after 5982 have been relocated. We have
revised paragraph (i)(4) of this AD accordingly.
Conclusion
We reviewed the relevant data, considered the comments received,
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 for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
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 130 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Retained actions: 20 work-hours $7,717............. $9,417............. $1,224,210.
x $85 per hour = $1,700.
New actions: Up to 170 work- Up to $41,635...... Up to $56,085...... Up to $7,291,050.
hours x $85 per hour = Up to
$14,450.
----------------------------------------------------------------------------------------------------------------
For the new maintenance/inspection program revision, we have
determined that this action takes an average of 90 work-hours per
operator, although we recognize that this number may vary from operator
to operator. In the past, we have estimated that this action takes 1
work-hour per airplane. Since operators incorporate maintenance or
inspection program changes for their affected fleet, we have determined
that a per-operator estimate is more accurate than a per-airplane
estimate. Therefore, we estimate the total cost per operator to be
$7,650 (90 work-hours x $85 per work-hour).
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all known costs in our cost
estimate.
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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes and
associated appliances to the Director of the System Oversight Division.
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),
(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.

might be referred to by the marketing designation CL-605.
(d) Subject
Air Transport Association (ATA) of America Code 29, Hydraulic
power.
(e) Reason
This AD was prompted by reports of on-ground hydraulic
accumulator screw cap or end cap failure that resulted in the loss
of the associated hydraulic system and high-energy impact damage to
adjacent systems and structure. We are issuing this AD to address
failure of one of the brake accumulator screw caps/end caps, which
could result in impact damage causing loss of both hydraulic systems
No. 2 and No. 3, and the consequent loss of both braking and nose
wheel steering, the potential for a runway excursion, and damage to
the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Part Number Inspection and Accumulator Replacement, With
Revised Formatting, Service Information, and Affected Part Numbers
This paragraph restates the requirements of paragraph (g) of AD
2010-14-05, with revised formatting, service information, and
affected part numbers. Do the following actions as applicable.
(1) Within 50 flight hours after August 5, 2010 (the effective
date of AD 2010-14-05), inspect to determine the part numbers of the
system accumulators numbers 1, 2, and 3, and brake accumulators
numbers 2 and 3 that are installed on the airplane. A review of
airplane maintenance records is acceptable in lieu of this
inspection if the part number of each accumulator can be
conclusively determined from that review. If all of the installed
accumulators have part number (P/N) 2770571-102, 2770571-103,
2770571-104, 2770571-105, 601R75139-3 (11094-4), or 601R75139-1
(11093-4), no further action is required by paragraph (g) of this
AD.
(2) Except as provided in paragraph (g)(1) of this AD: At the
applicable time in paragraph (g)(2)(i), (g)(2)(ii), or (g)(2)(iii)
of this AD, replace the accumulator with a new, overhauled, or
refurbished accumulator with the same part number, in accordance
with the Accomplishment Instructions of the applicable service
bulletin listed in figure 1 to paragraphs (g)(2) and (g)(3) of this
AD.
(i) For each accumulator having P/Ns 08-60163-002 (601R75138-1),
and 08-60164-002 (601R75138-3), as applicable, that has accumulated
more than 3,650 total flight cycles as of August 5, 2010 (the
effective date of AD 2010-14-05): Replace the accumulator within 100
flight cycles after August 5, 2010.
(ii) For each accumulator having P/N 08-60163-002 (601R75138-1),
and 08-60164-002 (601R75138-3), as applicable, that has accumulated
3,650 total flight cycles or fewer as of August 5, 2010: Replace the
accumulator before the accumulation of 3,750 total flight cycles on
the accumulator.
(iii) For each accumulator having P/N 08-60163-002 (601R75138-
1), and 08-60164-002 (601R75138-3), as applicable, for which it is
not possible to determine the number of flight cycles accumulated:
Replace the accumulator within 100 flight cycles after August 5,
2010.
[GRAPHIC] [TIFF OMITTED] TR23MY19.001
(3) Thereafter, before the accumulation of 3,750 total flight
cycles on any accumulator having P/Ns 08-60163-002 (601R75138-1),
and 08-60164-002 (601R75138-3), as applicable, replace the
accumulator with a new, overhauled, or refurbished accumulator
having the same part number, in accordance with the Accomplishment
Instructions of the applicable service bulletin listed in figure 1
to paragraphs (g)(2) and (g)(3) of this AD.
(h) New Provision of This AD: Terminating Action for Certain
Accumulators
For each accumulator with one of the part number and serial
number (S/N) suffixes listed in paragraphs (h)(1) through (h)(4) of
this AD, the repetitive replacement specified in paragraphs (g)(2)
and (g)(3) of this AD is not required.
(1) P/N 08-60163-002 with S/N suffix TNAE.
(2) P/N 08-60164-002 with S/N suffix TNAE.
(3) P/N 601R75139-3 (11094-4).
(4) P/N 601R75139-1 (11093-4).
(i) New Requirement of This AD: Relocation of Accumulators
Within 60 months or 2,400 flight cycles, whichever occurs first
after the effective date of this AD, relocate the hydraulic system
accumulators as specified in paragraphs (i)(1) through (i)(4) of
