Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

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.

DATES: This AD is effective October 5, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 5, 
2016.

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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     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.

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.
     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 
(for Model BD-700-1A10 airplanes).
     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 (for Model BD-700-1A11 airplanes).
     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 
(for Model BD-700-1A10 airplanes).
     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 (for 
Model BD-700-1A11 airplanes).
     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 (for 
Model BD-700-1A10 airplanes).
    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.
