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 VerDate Sep<11>2014 17:12 Dec 23, 2015 Jkt 238001 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-2014-06250003. 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.’’ PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 80237 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, E:\FR\FM\24DER1.SGM 24DER1 80238 Federal Register / Vol. 80, No. 247 / Thursday, December 24, 2015 / Rules and Regulations 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. 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. tkelley on DSK3SPTVN1PROD with RULES 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.

The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone 800–647–5527) is in the ADDRESSES section. 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.

SUPPLEMENTARY INFORMATION: We are adopting a new airworthiness directive (AD) for certain Airbus Model A330–200, A330–200 Freighter, and A330–300 series airplanes; and all Model A340–200 and A340–300 series airplanes. This AD was prompted by reports that a bracket that attaches the cockpit instrument panel to the airplane structure does not sustain the fatigue loads of the design service goal. This AD requires repetitive inspections of that bracket for cracking and to determine if both lugs are fully broken, an inspection for cracking of an adjacent bracket if necessary, and corrective actions if necessary. This AD also provides an optional modification, which terminates the repetitive inspections.

Airworthiness Directives; Bombardier, Inc. Airplanes

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.
