Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–42, dated December 12, 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– 600–2C10 (Regional Jet Series 700, 701, & 702) airplanes. The MCAI states: Cases of inboard MLG doors with cracked door forward members were found. A cracked inboard MLG door forward member could result in door departure from the aeroplane. Loss of an MLG door during flight could result in damage to the aeroplane and injury to persons on the ground. This [Canadian] AD mandates the repetitive inspection [and corrective actions if necessary] and replacement of the inboard MLG doors. The repetitive inspection is a detailed inspection for damage (including deformation, pulled or missing fasteners on the inner and outer skin, cracks, and deformation) on the forward member of the inboard MLG door inner skins, outer skin, and the forward member. Corrective actions include repairing, removing, or replacing the inboard MLG door. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 1987.

FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of these same type designs. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS Related Rulemaking AD 2010–23–19, Amendment 39– 16508 (75 FR 68695, November 9, 2010), requires repetitive inspections for damage of the MLG inboard doors and fairing, and corrective actions if necessary. AD 2010–23–19 applies to Model CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes having serial numbers (S/Ns) 10003 and subsequent; and Model CL–600–2D15 (Regional Jet Series 705) and CL–600– 2D24 (Regional Jet Series 900) airplanes having S/Ns 15001 and subsequent. VerDate Sep<11>2014 23:16 Jun 29, 2015 Jkt 235001 Costs of Compliance We estimate that this proposed AD affects 269 airplanes of U.S. registry. We estimate that it would take about 16 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work hour. Required parts would cost about $31,000 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $8,704,840, or $32,360 per product. In addition, we estimate that any necessary follow-on actions would take up to 44 work-hours and require parts costing up to $31,000, for a cost of up to $34,740 per product. We have no way of determining the number of aircraft that might need these actions. 37201 on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. Authority for This Rulemaking § 39.13 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: 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, PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 [Amended] 2.

14 CFR Part 39

[Docket No. FAA-2015-1987; Directorate Identifier 2014-NM-240-AD]
RIN 2120-AA64


Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 
701, & 702) airplanes. This proposed AD was prompted by reports of 
cracked forward door members of the inboard main landing gear (MLG) 
doors. This proposed AD would require repetitive inspections of the 
inboard MLG doors, repairs if necessary, and replacement of the inboard 
MLG doors. This proposed AD also would provide optional terminating 
action for the door replacement. We are proposing this AD to prevent 
loss of an MLG door during flight, which could result in damage to the 
airplane.

DATES: We must receive comments on this proposed AD by August 14, 2015.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-42, dated December 12, 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-
2C10 (Regional Jet Series 700, 701, & 702) airplanes. The MCAI states:

    Cases of inboard MLG doors with cracked door forward members 
were found. A cracked inboard MLG door forward member could result 
in door departure from the aeroplane. Loss of an MLG door during 
flight could result in damage to the aeroplane and injury to persons 
on the ground.
    This [Canadian] AD mandates the repetitive inspection [and 
corrective actions if necessary] and replacement of the inboard MLG 
doors.

    The repetitive inspection is a detailed inspection for damage 
(including deformation, pulled or missing fasteners on the inner and 
outer skin, cracks, and deformation) on the forward member of the 
inboard MLG door inner skins, outer skin, and the forward member.
    Corrective actions include repairing, removing, or replacing the 
inboard MLG door. You may examine the MCAI in the AD docket on the 
Internet at https://www.regulations.gov by searching for and locating 
Docket No. FAA-2015-1987.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Related Rulemaking

    AD 2010-23-19, Amendment 39-16508 (75 FR 68695, November 9, 2010), 
requires repetitive inspections for damage of the MLG inboard doors and 
fairing, and corrective actions if necessary. AD 2010-23-19 applies to 
Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes 
having serial numbers (S/Ns) 10003 and subsequent; and Model CL-600-
2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet Series 
900) airplanes having S/Ns 15001 and subsequent.

Costs of Compliance

    We estimate that this proposed AD affects 269 airplanes of U.S. 
registry.
    We estimate that it would take about 16 work-hours per product to 
comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work hour. Required parts would cost about 
$31,000 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be $8,704,840, or $32,360 per 
product.
    In addition, we estimate that any necessary follow-on actions would 
take up to 44 work-hours and require parts costing up to $31,000, for a 
cost of up to $34,740 per product. We have no way of determining the 
number of aircraft that might need these actions.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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.
