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.
DATES: We must receive comments on this proposed AD by April 18, 2016.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

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-
10-11, of Bombardier Global 6000 GL 6000 Time Limits/Maintenance
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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
