Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2015–03, dated March 13, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier Inc. Model BD– 700–1A10 and BD–700–1A11 airplanes. The MCAI states: E:\FR\FM\13JAP1.SGM 13JAP1 Federal Register / Vol. 81, No. 8 / Wednesday, January 13, 2016 / Proposed Rules There have been reports where operators experienced an inability to open the main passenger door following severe hot soak conditions. Investigation determined that the nylon slider in the plunger assembly of the door handle is susceptible to thermal expansion and permanent deformation at severe hot soak conditions, creating high friction between the spring pot housing and the slider. This condition, if not corrected, could result in an inability to open the main passenger door and could impede evacuation in the event of an emergency.

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– 8435. Related Service Information Under 1 CFR Part 51 Bombardier, Inc. has issued the following service information: • Bombardier Service Bulletin 700– 1A11–52–021, Revision 01, dated February 3, 2015. • Bombardier Service Bulletin 700– 52–044, Revision 01, dated February 3, 2015. • Bombardier Service Bulletin 700– 52–5008, Revision 01, dated February 3, 2015. • Bombardier Service Bulletin 700– 52–6008, Revision 01, dated February 3, 2015. The service information describes procedures to incorporate a new configuration to the passenger door external handle detent. 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. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS 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. VerDate Sep<11>2014 16:20 Jan 12, 2016 Jkt 238001 Costs of Compliance We estimate that this proposed AD affects 60 airplanes of U.S. registry. We also estimate that it would take about 4 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 $0 per product. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $20,400, or $340 per product. 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.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-03, dated March 13, 2015 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier Inc. Model BD-700-1A10 and BD-
700-1A11 airplanes. The MCAI states:


[[Page 1585]]


    There have been reports where operators experienced an inability 
to open the main passenger door following severe hot soak 
conditions.
    Investigation determined that the nylon slider in the plunger 
assembly of the door handle is susceptible to thermal expansion and 
permanent deformation at severe hot soak conditions, creating high 
friction between the spring pot housing and the slider.
    This condition, if not corrected, could result in an inability 
to open the main passenger door and could impede evacuation in the 
event of an emergency.
    This [Canadian] AD mandates the incorporation of a new 
configuration to the passenger door external handle detent to 
enhance the performance across the full range of the aeroplanes 
operating temperatures.

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.

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 60 airplanes of U.S. 
registry.
    We also estimate that it would take about 4 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 $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $20,400, or $340 per product.

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.

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-2015-8435; Directorate Identifier 
2015-NM-049-AD.

(a) Comments Due Date

    We must receive comments by February 29, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier Inc. Model BD-700-1A10 and BD-700-
1A11 airplanes, certificated in any category, serial numbers (S/N) 
9002 through 9515 inclusive and S/N 9998.

(d) Subject

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

(e) Reason

    This AD was prompted by reports of operator inability to open 
the main passenger door following severe hot soak conditions. We are 
issuing this AD to prevent thermal expansion and permanent 
deformation at severe hot soak conditions, creating high friction 
between the spring pot housing and the slider that could result in 
inability to open the main passenger door that could impede 
evacuation in the event of an emergency.

(f) Compliance

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

(g) Modification

    Within 15 months after the effective date of this AD, 
incorporate the new configuration to the passenger door external 
handle detent, in accordance with the Accomplishment Instructions of 
the applicable service information identified in paragraphs (g)(1) 
through (g)(4) of this AD:
