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-600-2C10 (Regional Jet Series 700, 701, & 
702) airplanes. This AD was prompted by reports of cracked forward door 
members of the inboard main landing gear (MLG) doors. This AD requires 
repetitive inspections of the inboard MLG doors, repairs if necessary, 
and replacement of the inboard MLG doors. This AD also provides 
optional terminating action for the door replacement. We are issuing 
this AD to prevent loss of an MLG door during flight, which could 
result in damage to the airplane.

DATES: This AD becomes effective February 25, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 25, 
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-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes. The 
NPRM published in the Federal Register on June 30, 2015 (80 FR 37200). 
The NPRM was prompted by reports of cracked forward door members of the 
inboard MLG doors. The NPRM proposed to require repetitive inspections 
of the inboard MLG doors, repairs if necessary, and replacement of the 
inboard MLG doors. The NPRM also proposed optional terminating action 
for the door replacement. We are issuing this AD to prevent loss of an 
MLG door during flight, which could result in damage to the airplane.

[[Page 3298]]

    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 skins 
and outer skin, and cracks) on the inner skins, outer skin, and the 
forward member of the inboard MLG doors. Corrective actions include 
repairing, removing, or replacing the inboard MLG door.
    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-1987-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the NPRM (80 FR 
37200, June 30, 2015) and the FAA's response to the comment.

Request To Revise Repair Instructions

    Envoy Airlines requested that we revise the wording in paragraph 
(i)(1)(ii)(A) of the proposed AD (80 FR 37200, June 30, 2015) to 
clarify that removal of the MLG door is not required in all repair 
situations. Envoy Airlines stated that Bombardier Service Bulletin 
670BA-32-042, Revision A, dated July 2, 2014, including Appendixes A 
and B, both dated November 5, 2013, specifies that repairs can be 
accomplished with the door installed in some situations. Envoy Airlines 
suggested that the text ``Repair and reinstall the door'' in paragraph 
(i)(1)(ii)(A) of the proposed AD be reworded to specify ``repair the 
door.''
    We agree with the commenter's request to revise the repair 
instructions. We have revised paragraph (i)(1)(ii)(A) of this AD by 
removing the instructions to reinstall the door.

Clarification of Actions

    We have clarified the inspection area in paragraph (g) of this AD 
by specifying to inspect for damage on the inner skins, outer skin, and 
the forward member of the inboard MLG doors.
    Paragraph (i)(1)(ii)(A) of the proposed AD (80 FR 37200, June 30, 
2015) specifies to do a repair ``if repair of the inboard MLG is 
possible.'' We have revised paragraph (i)(1)(ii)(A) of this AD to 
clarify the repair is done if it is possible to repair the inboard MLG 
door in accordance with the Accomplishment Instructions of Bombardier 
Service Bulletin 670BA-32-042, Revision A, dated July 2, 2014, 
including Appendixes A and B, both dated November 5, 2013.
    We have also revised paragraph (i)(1)(i) of this AD to specify that 
clarify that removed damaged doors cannot be reinstalled, unless the 
door is repaired prior to reinstallation and the actions specified in 
paragraph (l) of this AD are done.
    We have also clarified the actions required by paragraphs 
(i)(1)(iii), (i)(2), (k)(1), and (k)(2)(i) of this AD by specifying 
that where Bombardier Service Bulletin 670BA-32-043, Revision A, dated 
November 13, 2014, specifies to contact the manufacturer for certain 
instructions, this AD requires accomplishing those actions using a 
method approved by the Manager, New York ACO, ANE-170, FAA; or TCCA; or 
Bombardier, Inc.'s TCCA DAO.
    We have also revised paragraph (m) of this AD to refer to the 
latest revision of Bombardier Service Bulletin 670BA-32-043, dated July 
2, 2014. The ``Pre SB Part Number'' column of Section M, Relationship 
Chart, of Bombardier Service Bulletin 670BA-32-043, Revision A, dated 
November 13, 2014, is the same as that in Bombardier Service Bulletin 
670BA-32-043, dated July 2, 2014.

Conclusion

    We reviewed the relevant data, considered the comment 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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (80 FR 37200, June 30, 2015) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 37200, June 30, 2015).
    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.
    <bullet> Bombardier Modification Summary Package IS670528200033, 
Revision A-2, dated October 11, 2005. This service information 
describes procedures for enlarging the forward and aft hinge cutouts of 
the MLG inboard and outboard doors.
    <bullet> Bombardier Service Bulletin 670BA-32-040, Revision D, 
dated July 2, 2014, including Appendix A, Revision A, dated July 2, 
2014, and Appendix B, Revision B, dated July 2, 2014. This service 
information describes procedures for increasing the clearances between 
the MLG fairing and the MLG doors.
    <bullet> Bombardier Service Bulletin 670BA-32-040, Revision E, 
dated November 13, 2014, including Appendix A, Revision A, dated July 
2, 2014, and Appendix B, Revision B, dated July 2, 2014. This service 
information describes procedures for increasing the clearances between 
the MLG fairing and the MLG doors, and for enlarging the forward and 
aft hinge cutouts of the MLG inboard and outboard doors.
    <bullet> Bombardier Service Bulletin 670BA-32-042, Revision A, 
dated July 2, 2014, including Appendixes A and B, both dated November 
5, 2013. This service information describes procedures for inspecting 
and repairing the inboard MLG door inner skins, outer skin, and the 
forward member.
    <bullet> Bombardier Service Bulletin 670BA-32-043, dated July 2, 
2014; and Bombardier Service Bulletin 670BA-32-043, Revision A, dated 
November 13, 2014. This service information describes procedures for 
replacing the inboard MLG doors.
    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 of this 
AD.

Costs of Compliance

    We estimate that this AD affects 269 airplanes of U.S. registry.
    We estimate that it will take about 16 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work hour. Required parts will cost about $31,000 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $8,704,840, or $32,360 per product.

[[Page 3299]]

    In addition, we estimate that any necessary follow-on actions will 
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 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.
