[FR Doc. 2013–20110 Filed 8–29–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2013–0459; Directorate Identifier 2013–NM–044–AD; Amendment 39–17569; AD 2013–17–05] RIN 2120–AA64 Airworthiness Directives; Bombardier, Inc. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL–600–2D15 (Regional Jet Series 705) airplanes, Model CL–600–2D24 (Regional Jet Series 900) airplanes, and Model CL– 600–2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of erratic pitch movement and oscillatory behaviors of the elevator control system. This AD requires repetitive replacement of the bellcrank supports on the inner rear spar of the horizontal stabilizer with new, improved bellcrank supports. We are issuing this AD to prevent erratic pitch movement and transient accelerations, which could result in a significant pitch upset, and injuries to passengers and flightcrew. SUMMARY: This final rule becomes effective October 4, 2013. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of October 4, 2013.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The NPRM published in the Federal Register on May 31, 2013 (78 FR 32579). The NPRM proposed to correct an unsafe condition for the specified products. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–03, dated February 5, 2013 (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 have been several reported incidents of erratic pitch movements and oscillatory behaviors of the elevator control system. Investigation revealed that, the increase in the elevator breakout force induced by the introduction of a new elevator centering mechanism, in combination with the existing bracket assembly backlash and bearing friction of the bell crank support, could result in erratic pitch movement and oscillatory behavior of the elevator control system. This condition, if not corrected, could result in pitch upset of the aeroplane that generates transient accelerations. These accelerations could be high enough to injure aeroplane occupants that are not restrained in their seats. This [TCCA] AD mandates the repetitive replacement of the bellcrank supports with a new bearing. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. The Airline Pilots Association International supported the NPRM (78 FR 32579, May 31, 2013). Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting this final rule as proposed. Costs of Compliance We estimate that this AD affects 400 products of U.S. registry. We also estimate that it takes about 7 work-hours per product to comply with the basic requirements of this AD. Required parts would cost up to $2,422 per product. E:\FR\FM\30AUR1.SGM 30AUR1 Federal Register / Vol. 78, No. 169 / Friday, August 30, 2013 / Rules and Regulations The average labor rate is $85 per workhour. Based on these figures, we estimate the cost of this AD on U.S. operators to be up to $1,206,800, or up to $3,017 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. ehiers on DSK2VPTVN1PROD with RULES 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 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.

SUPPLEMENTARY INFORMATION: DATES: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. The NPRM was published in the Federal Register on May 20, 2013 (78 FR 29261). The NPRM proposed to correct an unsafe condition for the specified products. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0274, dated December 21, 2012 (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: One A330 operator recently reported a case where two adjacent frame (FR) forks of a forward cargo door were found cracked. FR20B was found cracked through, FR21 was found cracked half through. At the time of the findings, the affected aeroplane had accumulated around 21 000 flight cycles (FC) and it had already been inspected in accordance with EASA AD 2011–0007R1 [(http://ad.easa.europa.eu/blob/easa_ad_ 2011_0007_R1.pdf/AD_2011-0007R1_1)] [which corresponds to FAA AD 2012–12–12, Amendment 39–17092 (77 FR 37797, June 25, 2012)] and ALI [airworthiness limitation instructions] Task 523106–01–1. However, during those inspections, the forward cargo door handle access panel is not required to be removed, which explains why the cracks at these two internal frame locations were not detected. After further analysis, it was determined that, in case of cracked or ruptured (forward or aft) cargo door frame, the loads will be transferred to the remaining structural elements. However, the second load path is able to sustain the loads for a limited number of flight cycles only. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 This condition, if not detected and corrected, could lead to rupture of two vertical frames, resulting in reduced structural integrity of the forward or aft cargo door. To address this condition, Airbus issued four separate Alert Operators Transmissions (AOT), giving instructions for repetitive inspections of the affected areas. For the reasons described above, this [EASA] AD requires repetitive detailed visual inspections of aft cargo door at FR60 and FR60A [for certain airplanes] and forward cargo door at FR21 and FR20B [for all airplanes], where the cargo door handle access panels are located, as follow: —Outer skin rivets for sheared, loose or missing rivets at frame fork ends, —whole inner forks for cracks and for sheared, loose or missing rivets at frame web and flange after removal of handle access panels, and the accomplishment of the applicable corrective actions [which include repair, in accordance with a method approved by the Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA.] Note: Accomplishment of the above inspections does not cancel accomplishment of the inspections as required by EASA [AD] 2011–0007R1, nor accomplishment of those in accordance with ALI Task 523106–01–1. You may obtain further information by examining the MCAI in the AD docket. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 29261, May 20, 2013) or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed–except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 29261, May 20, 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 29261, May 20, 2013). Costs of Compliance We estimate that this AD affects 66 airplanes of U.S. registry. We also estimate that it takes 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 on U.S. operators to be $5,610, or $85 per product. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. E:\FR\FM\30AUR1.SGM 30AUR1

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 
702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes, 
Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-
600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by 
reports of erratic pitch movement and oscillatory behaviors of the 
elevator control system. This AD requires repetitive replacement of the 
bellcrank supports on the inner rear spar of the horizontal stabilizer 
with new, improved bellcrank supports. We are issuing this AD to 
prevent erratic pitch movement and transient accelerations, which could 
result in a significant pitch upset, and injuries to passengers and 
flightcrew.

DATES: This final rule becomes effective October 4, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of October 4, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM published in the Federal Register on May 31, 2013 (78 FR 
32579). The NPRM proposed to correct an unsafe condition for the 
specified products.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-03, dated February 5, 2013 (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 have been several reported incidents of erratic pitch 
movements and oscillatory behaviors of the elevator control system. 
Investigation revealed that, the increase in the elevator breakout 
force induced by the introduction of a new elevator centering 
mechanism, in combination with the existing bracket assembly 
backlash and bearing friction of the bell crank support, could 
result in erratic pitch movement and oscillatory behavior of the 
elevator control system. This condition, if not corrected, could 
result in pitch upset of the aeroplane that generates transient 
accelerations. These accelerations could be high enough to injure 
aeroplane occupants that are not restrained in their seats.
    This [TCCA] AD mandates the repetitive replacement of the 
bellcrank supports with a new bearing.

    You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. The Airline Pilots 
Association International supported the NPRM (78 FR 32579, May 31, 
2013).

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting 
this final rule as proposed.

Costs of Compliance

    We estimate that this AD affects 400 products of U.S. registry. We 
also estimate that it takes about 7 work-hours per product to comply 
with the basic requirements of this AD. Required parts would cost up to 
$2,422 per product.

[[Page 53639]]

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 up to $1,206,800, 
or up to $3,017 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 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains this AD, the MCAI, the regulatory 
evaluation, any comments received, and other information. The street
