Airworthiness Directives; Bombardier, Inc. Airplanes
Publication summary
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by in-service reports of passenger door tensator spring failures, and qualification testing indicating that non-conforming tensator springs could be susceptible to failure prior to reaching their safe-life limit. This AD requires revising the maintenance or inspection program to incorporate certain temporary revisions, and replacing the passenger door tensator springs with new springs. We are issuing 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.

-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD
was prompted by in-service reports of passenger door tensator spring
failures, and qualification testing indicating that non-conforming
tensator springs could be susceptible to failure prior to reaching
their safe-life limit. This AD requires revising the maintenance or
inspection program to incorporate certain temporary revisions, and
replacing the passenger door tensator springs with new springs. We are
issuing 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.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Bombardier, Inc.
Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the
Federal Register on March 4, 2016 (81 FR 11471) (``the NPRM'').
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-39, 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, 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.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment.
Request To Include Service Information
Bombardier, Inc. requested that we revise the Related Service
Information under 1 CFR part 51 section and paragraph (g) of the
proposed AD to include Temporary Revision (TR) 5-2-10, dated September
9, 2014, to Part 2, Section 5-10-11, of Bombardier Global 5000 GL 5000
Featuring Global Vision Flight Deck--Time Limits/Maintenance Checks.
We agree to include TR 5-2-10, dated June 4, 2014, to Part 2,
Section 5-10-11, of Bombardier Global 5000 GL 5000 Featuring Global
Vision Flight Deck--Time Limits/Maintenance Checks, as requested by the
commenter. Our intent is to correspond with TCCA Canadian AD CF-2014-
39, dated November 4, 2014, which includes TR 5-2-9, dated September 9,
2014, to Part 2, Section 5-10-11, of Bombardier Global 5000 GL 5000
Featuring Global Vision Flight
[[Page 59828]]
Deck--Time Limits/Maintenance Checks. TR 5-2-10, dated June 4, 2014,
supersedes TR 5-2-9, dated September 9, 2014. We have included TR 5-2-
10, dated June 4, 2014, in paragraph (g)(2) of this AD and redesignated
subsequent paragraph identifiers accordingly. We have also included
that same TR in the Related Service Information under 1 CFR part 51
section of this final rule. Since the NPRM inadvertently did not
include a TR to Part 2, Section 5-10-11, of Bombardier Global 5000 GL
5000 Featuring Global Vision Flight Deck--Time Limits/Maintenance
Checks, we must make this change to avoid operators needing to ask for
approval of an alternative method of compliance (AMOC) to use a TR in
order to comply with the revision required by paragraph (g) of this AD.
In addition, we have revised paragraph (g) of this AD to refer to
Task Number 52-11-41-101 because some TRs include multiple tasks. This
AD specifically addresses the passenger door tensator spring, part
number GS321-0580-1, and the task number in the TRs for that component
is 52-11-41-101.
Request To Correct Typographical Error
Bombardier, Inc. requested that we revise paragraph (g)(2) of the
proposed AD to read ``Model BD-700-1A10 airplanes,'' instead of ``Model
BD-700-1A11 airplanes.''
We agree. This was a typographical error, and has been corrected in
paragraph (g)(3) of this AD (paragraph (g)(2) of the proposed AD).
Request To Revise Compliance Time
NetJets requested that we revise the proposed AD so that the
threshold for the initial spring replacement is based on the AD
effective date, and not the TR revision date. NetJets explained that
paragraph (g) of the proposed AD specifies that the compliance time for
the initial replacement is per the TRs listed in paragraphs (g)(1)
through (g)(4) of the proposed AD, or within 30 days after the AD
effective date, whichever occurs later. NetJets explained further that
the TRs base the threshold from the TR revision date of ``Jun 04/
2014,'' and that by the time the final rule is released, the threshold
in the TR will have been exceeded by approximately 2 years. NetJets
argued that, therefore, the final rule will effectively mandate a 30-
day threshold, which is an undue burden without technical
justification.
We do not agree with the request to revise the compliance time in
this AD. The compliance time in this AD corresponds with the compliance
time in Canadian AD CF-2014-39, dated November 4, 2014. In addition,
the commenter did not provide any data to substantiate that extending
the compliance time would provide an acceptable level of safety. After
considering all the available information, we have determined that the
compliance time, as proposed, represents an appropriate interval of
time in which the required actions can be performed in a timely manner
within the affected fleet, while still maintaining an adequate level of
safety. Under the provisions of paragraph (k)(1) of this AD, however,
we may consider requests for adjustments to the compliance time if data
are submitted to substantiate that such an adjustment would provide an
acceptable level of safety. We have made no changes to this AD in this
regard.
Request To Allow for Later-Approved Revisions of Service Information
NetJets requested that we revise the NPRM to add provisions to
allow later FAA-approved revisions to the time limits/maintenance
checks manuals (TLMCM), so that an approval of an AMOC will not be
required to incorporate the currently published TLMCM revision and
future revisions. NetJets explained that the TRs specified in
paragraphs (g)(1) through (g)(4) of the proposed AD have been
incorporated in revisions to the listed TLMCMs.
We find that clarification is necessary. Once operators have
incorporated the task in the TR into their maintenance or inspection
program, the task cannot be changed without approval of an AMOC.
However, once the task in the TR is incorporated into the TLMCM,
operators that use the TLMCM are still in compliance because the task
has not changed. If a future revision of the TLMCM changes the task,
then an AMOC would be needed to use the revised task.
We have revised paragraph (g) of this AD to clarify that the
revision may be done by inserting copies of the TRs identified in
paragraphs (g)(1) through (g)(5) of this AD into the applicable TLMCM.
When the information in a TR has been included in general revisions of
the applicable TLMCM, the general revisions may be inserted in the
TLMCM, and the TR may be removed.
Request for Clarification of the Necessity for a Life Limit Requirement
NetJets requested that we clarify the necessity for the life limit
requirement in paragraph (i) of the proposed AD. NetJets stated that
paragraph (i) of the proposed AD requires a threshold of ``. . . but
not exceeding the applicable life limit of the passenger tensator
spring . . .'' without identifying the referenced life limit, and noted
that the listed service information does not include a life limit
requirement.
We agree to clarify the requirement specified in paragraph (i) of
this AD and the necessity for that requirement. 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. The actions required by
this AD are necessary to address the identified unsafe condition.
Paragraph (g) of this AD mandates the revision to the approved
maintenance schedule by incorporating TRs to reduce the repetitive
discard task interval. Paragraph (i) of this AD mandates, for certain
airplanes, the replacement of non-conforming tensator springs within 15
months after the effective date of this AD, but not exceeding the
applicable life limit of 1,500 landings for the component as listed in
the applicable TRs identified in paragraph (g) of this AD. The
replacement is necessary to ensure the airplanes identified in section
1.A., ``Effectivity,'' of Bombardier Global 5000 Service Bulletin 700-
1A11-52-023, dated October 4, 2013; or Bombardier Global Express/Global
Express XRS Service Bulletin 700-52-046, dated October 4, 2013, replace
the tensator springs within 15 months, as specified in that service
information, but not later than the new life limit. We have revised
paragraph (i) of this AD to refer to the TRs in paragraph (g) of this
AD for the life limit.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.

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.
Costs of Compliance
We estimate that this 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 AD. The average labor
rate is $85 per work-hour. Based on these figures, we estimate the cost
of this AD on U.S. operators to be $204,000, or $3,400 per product.
According to the manufacturer, some of the costs of this 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 AD will not have federalism implications
under Executive Order 13132. This AD will 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 that this AD:
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

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):
2016-17-16 Bombardier, Inc.: Amendment 39-18629. Docket No. FAA-
2016-3989; Directorate Identifier 2014-NM-220-AD.
(a) Effective Date
This AD is effective October 5, 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
9002 and subsequent.
(d) Subject
Air Transport Association (ATA) of America Code 52, Doors.
(e) Reason
This AD was prompted by in-service reports of passenger door
tensator spring failures, and qualification testing indicating that
non-conforming tensator springs could be susceptible to failure
prior to reaching their safe-life limit. We are issuing 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Maintenance or Inspection Program Revision
Within 30 days after the effective date of this AD, revise the
maintenance or inspection program, as applicable, to incorporate
task number 52-11-41-101 as specified in the Temporary Revisions
(TRs) identified in paragraphs (g)(1) through (g)(5) of this AD. The
compliance time for doing the initial replacement of the passenger
door tensator springs with new springs is at the times specified in
the applicable TR specified in paragraphs (g)(1) through (g)(5) of
this AD, or within 30 days after the effective date of this AD,
whichever occurs later. The revision required by this paragraph may
be done by inserting copies of the TRs identified in paragraphs
(g)(1) through (g)(5) of this AD into the applicable Time Limits/
Maintenance Checks manual. When the information in a TR has been
included in general revisions of the applicable Time Limits/
Maintenance Checks manual, the general revisions may be inserted in
the Time Limits/Maintenance Checks manual, and the TR may be
removed.
