AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
[[Page 80237]]
Bombardier, Inc. Model CL-600-2A12 (CL-601) and CL-600-2B16 (CL-601-3A,
CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by a
report of an aft equipment bay fire due to chafing and subsequent
arcing of the integrated drive generator (IDG) power cables.
Additionally, we have received several reports of broken support
brackets of the hydraulic line. This AD requires a one-time inspection
of the IDG power cables for chafing, and for any cracked or broken
support bracket of the hydraulic line; and corrective actions if
necessary. We are issuing this AD to detect and correct broken support
brackets of the hydraulic lines, which could result in inadequate
clearance between the IDG power cables and hydraulic lines and chafing
of the IDG power cables, and consequent high energy arcing and an
uncontrolled fire in the aft equipment bay.
DATES: This AD becomes effective January 28, 2016.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of January 28,
2016.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Bombardier, Inc.
Model 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 September 17, 2014 (79 FR 55673).
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-05, dated January 20, 2014 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:
There has been one reported case on the CL-600-2B19 aeroplane of
an aft equipment bay fire occurring due to arcing of chafed
integrated drive generator (IDG) power cables. Additionally, the
hydraulic line support brackets located at the fuselage station (FS)
672 and FS 682 on a CL-600-2B19 aeroplane could result in inadequate
clearance between the IDG power cables and hydraulic lines,
potentially resulting in chafing of the IDG power cables. Chafed IDG
power cables can generate high energy arcing, which can result in an
uncontrolled fire in the aft equipment bay.
It was found that a similar configuration exists on models CL-
600-2A12 and CL-600-2B16 aeroplanes. Therefore, a similar unsafe
condition exists.
This [Canadian] AD mandates the detailed visual inspection and,
if required, rectification of the IDG power cables and hydraulic
line support bracket.
Required corrective actions include repair or replacement of the
IDG power cable if any chafing is found, and replacement of any cracked
or broken support bracket. You may examine the MCAI in the AD docket on
the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-
0625-0003.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM (79
FR 55673, September 17, 2014) and the FAA's response to each comment.
Request To Correct Typographical Error
Bombardier asked that one of the service bulletin references
identified in the ``Relevant Service Information'' section of the NPRM
(79 FR 55673, September 17, 2014) be changed to correct a typographical
error. Bombardier Service Bulletin ``604-0625,'' as identified in the
``Relevant Service Information'' section, should be identified as
Bombardier Service Bulletin ``601-0625.''
We agree with the commenter for the reason provided, and we have
changed this reference to correctly specify Bombardier Service Bulletin
601-0625 throughout this final rule.
Request To Clarify Credit Provisions
Bombardier asked that we clarify the language in paragraph (h) of
the proposed AD, ``Credit for Previous Actions.'' Bombardier stated
that the current language may cause some confusion because the content
is not clear.
We acknowledge the commenter's concern, and we provide the
following clarification for the credit language used in paragraph (h)
of this AD. Paragraph (h) of this AD matches the intent of the last two
paragraphs in the ``Corrective Actions'' section of Canadian AD CF-
2014-05, dated January 20, 2014. Both this FAA AD and the Canadian AD
give credit for accomplishing Bombardier Service Bulletins 605-24-007,
604-24-026, and 601-0625, all dated September 18, 2012, but only if
Service Request for Product Support Action (SRPSA) 27512, SRPSA 30806,
SRPSA 32727, SRPSA 32864, or SRPSA 33161 has not been done.
Clarification of Airplane Models
We have included the airplane models identified in the service
information in the ``Related Service Information under 1 CFR part 51''
section, and paragraphs (g)(1), (g)(2), and (g)(3) of this AD (79 FR
55673, September 17, 2014), for clarification.
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 (79 FR 55673, September 17, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 55673, September 17, 2014).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.
Related Service Information Under 1 CFR Part 51
Bombardier has issued the following service information:
Bombardier Service Bulletin 605-24-007, Revision 01, dated
January 13,
[[Page 80238]]
2014 (for Model CL-600-2B16 airplanes (CL-604 Variant));
Bombardier Service Bulletin 604-24-026, Revision 01, dated
January 13, 2014 (for Model CL-600-2B16 airplanes (CL-604 Variant));
and
Bombardier Service Bulletin 601-0625, Revision 01, dated
January 13, 2014 (for Model CL-600-2A12 (CL-601) and CL-600-2B16
airplanes (CL-601-3A and CL-601-3R Variants)).
This service information describes procedures for a one-time
inspection of the IDG power cables for chafing, and for any cracked or
broken support bracket of the hydraulic line; and corrective actions if
necessary. This service information is reasonably available because the
interested parties have access to it through their normal course of
business or by the means identified in the ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 95 airplanes of U.S. registry.
We also estimate that it takes about 1 work-hour per product to
comply with the 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 $8,075, or $85 per product.
We have received no definitive data that would enable us to provide
cost estimates for the on-condition repair of chafed power cables or
cracked or broken support brackets, as specified in 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 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.
