Discussion Transport Canada Civil Aviation, which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–41, dated December 30, 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: E:\FR\FM\01JYP1.SGM 01JYP1 Federal Register / Vol. 79, No. 126 / Tuesday, July 1, 2014 / Proposed Rules A check tee fitting used in the aeroplane fire extinguishing (FIREEX) distribution lines, was discovered by another airframe manufacturer as being incorrectly assembled. A properly assembled check tee fitting normally contains one check ball, however the affected fitting contained two check balls. The FIREEX manufacturer advised Bombardier that this condition may be present on aeroplane models BD–700–1A10 and BD–700–1A11. Testing has verified that incorrect installation of the additional check ball in the fitting reduces the flow rate of the extinguishing agent. There are three check tee fittings installed on the BD–700–1A10 and BD–700–1A11 aeroplanes, one for each engine and one for the auxiliary power unit. Faulty fittings will reduce fire extinguishing protection at the affected locations. Bombardier has issued several Alert Service Bulletins (ASBs) to identify, inspect and replace if required, all affected fittings. This [Canadian] AD mandates incorporation of the applicable Bombardier ASBs to rectify this problem. tkelley on DSK3SPTVN1PROD with PROPOSALS Required actions include inspecting to determine the part number and for all affected check tee fittings measuring for correct depth, and replacing if necessary. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA– 2014–0424. Relevant Service Information Bombardier, Inc. has issued the following service bulletins. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. • Bombardier Alert Service Bulletin A700–1A11–26–003, dated April 18, 2013 (for Model BD–700–1A11 (BD– 700) airplanes having S/Ns 9127 through 9383 inclusive; 9389 through 9400 inclusive, 9404 through 9431 inclusive, and 9998). • Bombardier Alert Service Bulletin A700–26–010, dated April 18, 2013 (for Model BD–700–1A10 (BD–700) airplanes having S/Ns 9002 through 9312 inclusive, 9314 through 9380 inclusive, and 9384 through 9429 inclusive). • Bombardier Alert Service Bulletin A700–26–5002, dated April 18, 2013 (for Model BD–700–1A11 (BD–700) airplanes having S/Ns 9386, 9401, and 9445 through 9498 inclusive). • Bombardier Alert Service Bulletin A700–26–6002, dated April 18, 2013 (for Model BD–700–1A10 (BD–700) airplanes having S/Ns 9313, 9381, and 9432 through 9500 inclusive). FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another VerDate Mar<15>2010 16:47 Jun 30, 2014 Jkt 232001 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 57 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 $4,845, or $85 per product. In addition, we estimate that any necessary follow-on actions would take about 1 work-hour, for a cost of $85 per tee fitting. We have no way of determining the number of aircraft that might need this action. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 proposed 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 PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 37247 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.

Discussion

    Transport Canada Civil Aviation, which is the aviation authority 
for Canada, has issued Canadian Airworthiness Directive CF-2013-41, 
dated December 30, 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:


[[Page 37247]]


    A check tee fitting used in the aeroplane fire extinguishing 
(FIREEX) distribution lines, was discovered by another airframe 
manufacturer as being incorrectly assembled. A properly assembled 
check tee fitting normally contains one check ball, however the 
affected fitting contained two check balls. The FIREEX manufacturer 
advised Bombardier that this condition may be present on aeroplane 
models BD-700-1A10 and BD-700-1A11.
    Testing has verified that incorrect installation of the 
additional check ball in the fitting reduces the flow rate of the 
extinguishing agent. There are three check tee fittings installed on 
the BD-700-1A10 and BD-700-1A11 aeroplanes, one for each engine and 
one for the auxiliary power unit. Faulty fittings will reduce fire 
extinguishing protection at the affected locations.
    Bombardier has issued several Alert Service Bulletins (ASBs) to 
identify, inspect and replace if required, all affected fittings. 
This [Canadian] AD mandates incorporation of the applicable 
Bombardier ASBs to rectify this problem.

    Required actions include inspecting to determine the part number 
and for all affected check tee fittings measuring for correct depth, 
and replacing if necessary. You may examine the MCAI in the AD docket 
on the Internet at http://www.regulations.gov by searching for and 
locating it in Docket No. FAA-2014-0424.

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 57 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 $4,845, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour, for a cost of $85 per tee fitting. We have no 
way of determining the number of aircraft that might need this action.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 proposed 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.
