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, Model CL-600-2D24 (Regional Jet Series 900) 
airplanes, and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. 
This proposed AD was prompted by a report that certain parts of the aft 
baggage door did not conform to the design specifications and were of 
degraded strength. This proposed AD would require repetitive 
inspections for cracking and deformations of certain stop fittings and 
striker plates of the aft baggage bay door; and replacement, which 
would terminate the repetitive inspections. We are proposing this AD to 
prevent cracking and deformations of certain stop fittings and striker 
plates, which may result in the opening of the aft baggage bay door and 
rapid decompression or reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by July 14, 2014.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-37, dated November 28, 2013 (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, Model CL-600-2D24 
(Regional Jet Series 900) airplanes, and Model CL-600-2E25 (Regional 
Jet Series 1000) airplanes. The MCAI states:


[[Page 30752]]


    During the manufacturing process, it was found that certain aft 
baggage bay door stop fittings and striker plates did not conform to 
the design specifications due to a quality control problem. This 
quality escape could degrade the strength of the affected aft 
baggage bay door stop fittings and striker plates. Failure of the 
aft baggage bay door stop fittings or striker plates may result in 
the opening of the aft baggage bay door and consequent rapid 
decompression of the aeroplane during flight.
    This [Canadian] AD mandates the initial and repetitive 
inspections of each aft baggage bay door stop fitting and striker 
plate until the terminating action [stop fitting/striker plate 
replacement] is accomplished.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
0287.

Relevant Service Information

    Bombardier, Inc. has issued Service Bulletin 670BA-52-037, Revision 
B, dated September 16, 2013. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.

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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 73 airplanes of U.S. 
registry.
    We also estimate that it would take about 1 work-hour 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 $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $6,205, or $85 per product.
    In addition, we estimate that any necessary follow-on action would 
take about 22 work-hours and require parts costing $0, for a cost of 
$1,870 per product. We have no way of determining the number of 
aircraft that might need this action.

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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2014-0287; Directorate Identifier 
2013-NM-247-AD.

(a) Comments Due Date

    We must receive comments by July 14, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Bombardier, Inc. airplanes specified in 
paragraphs (c)(1), (c)(2), and (c)(3) of this AD; certificated in 
any category.
    (1) Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) 
airplanes, serial numbers 10303 through 10333 inclusive.
    (2) Model CL-600-2D24 (Regional Jet Series 900) airplanes,

serial numbers 19011 through 19024 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 52, Doors.

(e) Reason

    This AD was prompted by a report that certain stop fittings and 
striker plates of the aft baggage bay door did not conform to the 
design specifications; this quality escape could degrade the 
strength of the affected stop fittings and striker plates of the aft 
baggage bay door. We are issuing this AD to prevent cracking and 
deformations of stop fittings and striker plates, which may result 
in the opening of the aft baggage bay door and rapid decompression 
or reduced controllability of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspections of the Aft Baggage Bay Door Stop Fittings and Striker 
Plates

    Within 600 flight hours or 6 months after the effective date of 
this AD, whichever occurs first, do a detailed visual inspection for 
cracking and deformations of the stop fittings and striker plates of 
the aft baggage bay door, in accordance with the Accomplishment 
Instructions of Bombardier Service Bulletin 670BA-52-037, Revision 
B, dated September 16, 2013. Repeat the inspection thereafter at 
intervals not to exceed 2,000 flight hours or 12 months, whichever 
occurs first, until the terminating action specified in paragraph 
(h) of this AD has been accomplished. If a crack or deformation is 
found on a stop fitting or striker plate, before further flight, 
replace the affected fittings and striker plates, in accordance with 
the Accomplishment Instructions in Bombardier Service Bulletin 
670BA-52-037, Revision B, dated September 16, 2013.

[[Page 30753]]

(h) Terminating Action--Replacement of the Aft Baggage Bay Door Stop 
Fittings and Striker Plates

    Within 6,000 flight hours or 36 months, whichever occurs first, 
after the effective date of this AD, replace the affected stop 
fittings and striker plates, in accordance with the Accomplishment 
Instructions of Bombardier Service Bulletin 670BA-52-037, Revision 
B, dated September 16, 2013. Replacement of the affected stop 
fittings and striker plates of the aft baggage bay door constitutes 
terminating action for the repetitive inspections required by 
paragraph (g) of this AD.
