We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by in-service reports of passenger door tensator spring failures, and qualification testing that determined that non-conforming tensator springs could be susceptible to failure prior to reaching their safe-life limit. This proposed AD would require revising the maintenance or inspection program to incorporate certain temporary revisions, and replacing the passenger door tensator springs with new springs. We are proposing this AD to prevent tensator spring failure, resulting in the inability to open the main passenger door, which could impede evacuation in the event of an emergency.

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 BD-700-1A10 and BD-700-1A11 airplanes. 
This proposed AD was prompted by in-service reports of passenger door 
tensator spring failures, and qualification testing that determined 
that non-conforming tensator springs could be susceptible to failure 
prior to reaching their safe-life limit. This proposed AD would require 
revising the maintenance or inspection program to incorporate certain 
temporary revisions, and replacing the passenger door tensator springs 
with new springs. We are proposing this AD to prevent tensator spring 
failure, resulting in the inability to open the main passenger door, 
which could impede evacuation in the event of an emergency.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-39,

[[Page 11472]]

dated November 4, 2014 (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:

    Following the issuance of [Canadian] AD CF-2010-14 [http://wwwapps3.tc.gc.ca/Saf-Sec-Sur/2/cawis-swimn/awd-display-cs2101-wnd.asp?rand=&vMode=0&showPdf=False&ovid=CF_CF-2010-14_0], 
additional qualification testing of the passenger door tensator 
spring, Part Number (P/N) GS321-0580-1, determined that the tensator 
springs could be susceptible to failure prior to reaching the life 
limit mandated by [Canadian] AD CF-2010-14.
    In addition, there have been in-service reports of passenger 
door tensator spring failures. Investigation determined that the 
material used to manufacture the tensator springs [was] improperly 
heat treated.
    The passenger door assembly is installed with four tensator 
springs that assist the door actuator in opening and closing the 
door. In-service experience has shown that a failed tensator spring 
could uncoil and foul up the rotating tensator spools, resulting in 
the inability to open the main passenger door. The inability to open 
the main passenger door could impede evacuation in the event of an 
emergency.
    This [Canadian] AD mandates the revision to the approved 
maintenance schedule to reduce the repetitive discard task interval 
and mandates the replacement of non-conforming tensator springs.

    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-2016-
3989.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Bombardier, Inc. service information:
     Bombardier Global 5000 Service Bulletin 700-1A11-52-023, 
dated October 4, 2013.
     Bombardier Global Express/Global Express XRS Service 
Bulletin 700-52-046, dated October 4, 2013.
     Temporary Revision (TR) 5-2-7, dated June 4, 2014, to Part 
2, Section 5-10-11, of Bombardier Global Express XRS BD-700 Time 
Limits/Maintenance Checks.
     TR 5-2-10, dated September 9, 2014, to Part 2, Section 5-

Checks.
     TR 5-2-13, dated June 4, 2014, to Part 2, Section 5-10-11, 
of Bombardier Global 5000 BD-700 Time Limits/Maintenance Checks.
     TR 5-2-44, dated June 4, 2014, to Part 2, Section 5-10-11, 
of Bombardier Global Express BD-700 Time Limits/Maintenance Checks.
    The service information describes procedures for replacing 
passenger door tensator springs with new springs. 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.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 60 airplanes of U.S. 
registry.
    We also estimate that it would take about 40 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $204,000, or 
$3,400 per product.
    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 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.
