AGENCY: VerDate Sep<11>2014 14:33 Apr 29, 2015 Jkt 235001 We are adopting a new airworthiness directive (AD) 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. This AD was prompted by a determination that the forward lugs of the flap hinge box might not conform to engineering drawings, which could result in premature fatigue cracking. This AD requires revising the maintenance or inspection program to include new airworthiness limitations tasks; and measuring the forward lug edge distance of each flap hinge box, inspecting for cracking and damage (i.e., deformation or bearing failure) of the forward lug edge of each flap hinge box, and repairing any cracking or damage if necessary. We are issuing this AD to detect and correct non-conforming flap hinge box forward lugs, which could result in failure of the lugs and detachment of the flap hinge box and consequent detachment of the flap surface. DATES: This AD becomes effective June 4, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 4, 2015.

SUMMARY: PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 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–600–1A11 (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 August 4, 2014 (79 FR 45140). The NPRM was prompted by a determination that the forward lugs of the flap hinge box might not conform to engineering drawings, which could result in premature fatigue cracking. The NPRM proposed to require revising the maintenance or inspection program to include new airworthiness limitations tasks; and measuring the forward lug edge distance of each flap hinge box, inspecting for cracking and damage (i.e., deformation or bearing failure) of the forward lug edge of each flap hinge box, and repairing any cracking or damage if necessary. We are issuing this AD to detect and correct non-conforming flap hinge box forward lugs, which could result in failure of the lugs and detachment of the flap hinge box and consequent detachment of the flap surface. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–01, dated January 3, 2014 (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: The aeroplane manufacturer has determined that the flap hinge box forward lugs edge distance may not conform to the engineering drawings. Non-conforming flap hinge box forward lugs may result in premature fatigue cracking. Failure of the lugs could lead to the detachment of the flap hinge box and consequently the detachment of the flap surface. The loss of a flap surface could adversely affect the continued safe operation of the aeroplane. This [Canadian] AD mandates the incorporation of new Time Limits/ Maintenance Checks (TLMC) Airworthiness Limitations (AWL) tasks, and the measurement [and inspection for cracking and damage] of the forward lug edge distance of each flap hinge-box and rectification as required. Corrective actions include repairing damage and cracking. You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/ E:\FR\FM\30APR1.SGM 30APR1 Federal Register / Vol. 80, No. 83 / Thursday, April 30, 2015 / Rules and Regulations #!documentDetail;D=FAA-2014-04910002. Explanation of Additional Change Made to This Final Rule Comments We have removed Note 1 to paragraph (g) from this final rule. Instead, we have included that information in paragraph (g) of this AD. We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 45140, August 4, 2014) and the FAA’s response to each comment. Request To Include Latest Revision of Service Information Bombardier, Inc. requested that we revise the NPRM (79 FR 45140, August 4, 2014) to reflect the latest revisions of certain service information. We agree to include the latest revisions of certain service information. Bombardier has issued Service Bulletin 604–57–007, Revision 01, dated November 12, 2014 (for Model CL–600– 2B16 airplanes); and Service Bulletin 605–57–005, Revision 01, dated November 12, 2014 (for Model CL–600– 2B16 airplanes). This new service information does not add new work for the affected airplanes and was revised to update labor hours needed to perform the work and clarify work instructions. We have changed this AD to reference Bombardier Service Bulletin 604–57– 007, Revision 01, dated November 12, 2014; and Bombardier Service Bulletin 605–57–005, Revision 01, dated November 12, 2014, throughout. We have also added a new paragraph (k) to this AD to give credit for actions performed before the effective date of this AD using Bombardier Service Bulletin 604–57–007, dated September 26, 2013; and Bombardier Service Bulletin 605–57–005, dated September 26, 2013. We redesignated subsequent paragraphs accordingly. rmajette on DSK2VPTVN1PROD with RULES Request To Correct Typographical Errors Bombardier, Inc., and an FAA airframe and powerplant mechanic noted typographical errors in Table 1 of the NPRM (79 FR 45140, August 4, 2014) and requested they be corrected. We agree that there are typographical errors. We have revised table 1 to paragraph (g) of this AD. The temporary revision (TR) number has been corrected to read ‘‘5–275,’’ in certain rows of table 1 to paragraph (g) of this AD, where in the NPRM (79 FR 45140, August 4, 2014) the previous TR number read ‘‘5– 276.’’ The revision of Bombardier CL– 604 Time Limits/Maintenance Checks Manual, dated July 8, 2013, was corrected from revision ‘‘8’’ to revision ‘‘20.’’ VerDate Sep<11>2014 14:33 Apr 29, 2015 Jkt 235001 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 45140, August 4, 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 45140, August 4, 2014). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

We also estimate that it will take about 45 work-hours 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. VerDate Sep<11>2014 14:33 Apr 29, 2015 Jkt 235001 operators to be $401,625, or $3,825 per product. We have received no definitive data that would enable us to provide cost estimates for the cost of parts or oncondition actions 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.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Airbus Model A318–111 and –112 airplanes and Model A319, A320, and A321 series airplanes. This AD was prompted by reports of cracks on the forward corner fittings of engine pylon aft secondary structures. This AD requires repetitive inspections of certain forward corner fittings of the pylon aft secondary structures, and corrective actions if necessary. This AD also provides optional terminating action for the repetitive inspections. We are issuing this AD to detect and correct detachment of the lower fairing attachment and/or loss of the aft fixed fairing with the movable fairing from the airplane in flight, which could result in damage to the airplane. DATES: This AD becomes effective June 4, 2015. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 4, 2015. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov/ rmajette on DSK2VPTVN1PROD with RULES SUMMARY: VerDate Sep<11>2014 14:33 Apr 29, 2015 Jkt 235001 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A318– 111 and –112 airplanes and Model A319, A320, and A321 series airplanes. The NPRM published in the Federal Register on September 3, 2014 (79 FR 52267). The NPRM was prompted by reports of cracks on the forward corner fittings of engine pylon aft secondary structures. The NPRM proposed to require repetitive inspections of certain forward corner fittings of the pylon aft secondary structures, and corrective actions if necessary. The NPRM also proposed to provide optional terminating action for the repetitive inspections. We are issuing this AD to detect and correct detachment of the lower fairing attachment and/or loss of the aft fixed fairing with the movable fairing from the airplane in flight, which could result in damage to the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0064, dated March 14, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition. The MCAI states: PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 24207 Several operators of A320 family aeroplanes have reported finding cracks on the forward corner fittings of engine pylon aft secondary structures, on the lateral face (lateral panel side). In some cases, these cracks had propagated onto the forward face (Rib 11 side). Investigation results have highlighted that these cracks are initiated by stress corrosion. This condition, if not detected and corrected, could lead to loss (i.e. detachment from the aeroplane) of the lower fairing attachment at Rib 10, and/or loss of the aft fixed fairing with the movable fairing, possibly resulting in * * * [damage to the airplane]. For the reasons described above, this [EASA] AD requires repetitive detailed inspections (DI) of the right hand (RH) Part Number (P/N) D54530014201 and left hand (LH) P/N D54530014200 corner fittings of engine pylon aft secondary structures (premod 38067 or pre-Airbus Service Bulletin (SB) A320–54–1019) to detect cracks or deformation in the splicing area with corner fitting between Ribs 11–12 and, depending on findings, replacement of the corner fittings. This [EASA] AD also recognizes that replacement of the corner fittings with improved parts (as per Airbus SB A320–54– 1019) constitutes a terminating action for the repetitive DI required by this [EASA] AD. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov/ #!documentDetail;D=FAA-2014-05890003. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 52267, September 3, 2014) and the FAA’s response to each comment.

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 
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. This 
AD was prompted by a determination that the forward lugs of the flap 
hinge box might not conform to engineering drawings, which could result 
in premature fatigue cracking. This AD requires revising the 
maintenance or inspection program to include new airworthiness 
limitations tasks; and measuring the forward lug edge distance of each 
flap hinge box, inspecting for cracking and damage (i.e., deformation 
or bearing failure) of the forward lug edge of each flap hinge box, and 
repairing any cracking or damage if necessary. We are issuing this AD 
to detect and correct non-conforming flap hinge box forward lugs, which 
could result in failure of the lugs and detachment of the flap hinge 
box and consequent detachment of the flap surface.

DATES: This AD becomes effective June 4, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 4, 2015.

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-600-1A11 (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 August 4, 2014 (79 FR 45140). The NPRM was 
prompted by a determination that the forward lugs of the flap hinge box 
might not conform to engineering drawings, which could result in 
premature fatigue cracking. The NPRM proposed to require revising the 
maintenance or inspection program to include new airworthiness 
limitations tasks; and measuring the forward lug edge distance of each 
flap hinge box, inspecting for cracking and damage (i.e., deformation 
or bearing failure) of the forward lug edge of each flap hinge box, and 
repairing any cracking or damage if necessary. We are issuing this AD 
to detect and correct non-conforming flap hinge box forward lugs, which 
could result in failure of the lugs and detachment of the flap hinge 
box and consequent detachment of the flap surface.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-01, dated January 3, 2014 (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:

    The aeroplane manufacturer has determined that the flap hinge 
box forward lugs edge distance may not conform to the engineering 
drawings. Non-conforming flap hinge box forward lugs may result in 
premature fatigue cracking.
    Failure of the lugs could lead to the detachment of the flap 
hinge box and consequently the detachment of the flap surface. The 
loss of a flap surface could adversely affect the continued safe 
operation of the aeroplane.
    This [Canadian] AD mandates the incorporation of new Time 
Limits/Maintenance Checks (TLMC) Airworthiness Limitations (AWL) 
tasks, and the measurement [and inspection for cracking and damage] 
of the forward lug edge distance of each flap hinge-box and 
rectification as required.

    Corrective actions include repairing damage and cracking. You may 
examine the MCAI in the AD docket on the Internet at https://
www.regulations.gov/

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (79 
FR 45140, August 4, 2014) and the FAA's response to each comment.

Request To Include Latest Revision of Service Information

    Bombardier, Inc. requested that we revise the NPRM (79 FR 45140, 
August 4, 2014) to reflect the latest revisions of certain service 
information.
    We agree to include the latest revisions of certain service 
information. Bombardier has issued Service Bulletin 604-57-007, 
Revision 01, dated November 12, 2014 (for Model CL-600-2B16 airplanes); 
and Service Bulletin 605-57-005, Revision 01, dated November 12, 2014 
(for Model CL-600-2B16 airplanes). This new service information does 
not add new work for the affected airplanes and was revised to update 
labor hours needed to perform the work and clarify work instructions. 
We have changed this AD to reference Bombardier Service Bulletin 604-
57-007, Revision 01, dated November 12, 2014; and Bombardier Service 
Bulletin 605-57-005, Revision 01, dated November 12, 2014, throughout. 
We have also added a new paragraph (k) to this AD to give credit for 
actions performed before the effective date of this AD using Bombardier 
Service Bulletin 604-57-007, dated September 26, 2013; and Bombardier 
Service Bulletin 605-57-005, dated September 26, 2013. We redesignated 
subsequent paragraphs accordingly.

Request To Correct Typographical Errors

    Bombardier, Inc., and an FAA airframe and powerplant mechanic noted 
typographical errors in Table 1 of the NPRM (79 FR 45140, August 4, 
2014) and requested they be corrected.
    We agree that there are typographical errors. We have revised table 
1 to paragraph (g) of this AD. The temporary revision (TR) number has 
been corrected to read ``5-275,'' in certain rows of table 1 to 
paragraph (g) of this AD, where in the NPRM (79 FR 45140, August 4, 
2014) the previous TR number read ``5-276.'' The revision of Bombardier 
CL-604 Time Limits/Maintenance Checks Manual, dated July 8, 2013, was 
corrected from revision ``8'' to revision ``20.''

 Explanation of Additional Change Made to This Final Rule

    We have removed Note 1 to paragraph (g) from this final rule. 
Instead, we have included that information in paragraph (g) of this AD.

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 45140, August 4, 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 45140, August 4, 2014).
    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 105 airplanes of U.S. registry.
    We also estimate that it will take about 45 work-hours 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 $401,625, or $3,825 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the cost of parts or on-condition actions 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.
