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: E:\FR\FM\29MYP1.SGM 29MYP1 30752 Federal Register / Vol. 79, No. 103 / Thursday, May 29, 2014 / Proposed Rules 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 https:// 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. emcdonald on DSK67QTVN1PROD with PROPOSALS 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. VerDate Mar<15>2010 16:51 May 28, 2014 Jkt 232001 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, 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.

AGENCY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model DC–9–10, DC–9–20, and DC–9–30 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the improved (shot-peened) aft fuselage non-ventral pressure bulkhead tee is subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections for cracking of the improved (shot-peened) non-ventral aft pressure bulkhead tees, and replacement if necessary. We are proposing this AD to detect and correct fatigue cracking of the improved (shotpeened) non-ventral aft pressure bulkhead dome tees connecting the bulkhead web to the fuselage, which could result in reduced structural integrity and rapid decompression of the airplane.

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 https://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.

List of Subjects in 14 CFR Part 39

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
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 15257 through 15284 inclusive.
    (3) Model CL-600-2E25 (Regional Jet Series 1000) 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.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, New 
York Aircraft Certification Office (ACO), ANE-170, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the ACO, send it to ATTN: Program Manager, Continuing 
Operational Safety, FAA, New York ACO, 1600 Stewart Avenue, Suite 
410, Westbury, NY 11590; telephone 516-228-7300; fax 516-794-5531. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer, use these actions if they 
are FAA-approved. Corrective actions are considered FAA-approved if 
they were approved by the State of Design Authority (or its 
delegated agent, or the Design Approval Holder with a State of 
Design Authority's design organization approval, as applicable). You 
are required to ensure the product is airworthy before it is 
returned to service.
