Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (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 reports of aileron and rudder control 
cables which may have tensions that are beyond allowable limits. This 
proposed AD would require revising the maintenance or inspection 
program to incorporate certification maintenance requirement tasks that 
introduce functional tests of the control cable tension. We are 
proposing this AD to detect and correct out-of-tolerance tension in the 
control cables, which, with certain system failures and environmental 
conditions, could result in reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by December 22, 
2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.
     Fax: 202-493-2251.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-06R1, dated July 25, 2016 (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:

    Recent in-service inspections have shown that aileron and rudder 
control cables may have tensions beyond allowable limits. Review of 
the technical documentation found that there are no maintenance 
tasks to detect and rectify out-of-tolerance tensions on these 
cables. Out of tolerance cables in combinations with certain system 
failures and environmental conditions could result in the degraded 
aircraft controllability.
    * * * [This Canadian] AD was issued to mandate a revision to the 
approved maintenance schedule [maintenance or inspection program, as 
applicable] to introduce cable tension check [e.g., functional 
test,] as [certification maintenance requirement] tasks.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9304.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(j)(1) of this proposed AD. The request should include a description of 
changes to the required actions that will ensure the continued 
operational safety of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Bombardier, Inc. service information:
     Temporary Revision (TR) 5-2-10, dated November 24, 2015, 
to Part 2, Section 5-10-40, of Bombardier Global Express XRS BD-700 
Time Limits/Maintenance Checks.
     TR 5-2-15, dated November 24, 2015, to Part 2, Section 5-
10-40, of Bombardier Global 6000 GL 6000 Time Limits/Maintenance 
Checks.
     TR 5-2-15, dated November 24, 2015, to Part 2, Section 5-
10-40, of Bombardier Global 5000 GL 5000 Featuring Global Vision Flight 
Deck--Time Limits/Maintenance Checks.
     TR 5-2-16, dated November 24, 2015, to Part 2, Section 5-
10-40, of Bombardier Global 5000 BD-700 Time Limits/Maintenance Checks.
     TR 5-2-47, dated November 24, 2015, to Part 2, Section 5-
10-40, of Bombardier Global Express BD-700 Time Limits/Maintenance 
Checks.
    The service information identifies airworthiness limitation tasks 
for functional tests of the cable tension of the aileron and rudder 
control cables. 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 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 issuing this AD because we 
evaluated all pertinent information and determined the 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 estimate the following costs to comply with this proposed AD:

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

[[Page 78082]]

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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2016-9304; Directorate Identifier 
2016-NM-028-AD.

(a) Comments Due Date

    We must receive comments by December 22, 2016.

(b) Affected ADs

controls.

(e) Reason

    This AD was prompted by reports of aileron and rudder control 
cables which may have tensions that are beyond allowable limits. We 
are issuing this AD to detect and correct out-of-tolerance tension 
in the control cables, which, with certain system failures and 
environmental conditions, could result in reduced controllability of 
the airplane.

(f) Compliance

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

(g) Time Limits/Maintenance Checks (TLMC)--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 
certification maintenance requirement (CMR) tasks 27-11-35-101, 27-
11-35-102, and 27-21-27-101 (for functional tests of the control 
cable tension) as specified in the applicable service information in 
paragraphs (g)(1) through (g)(5) of this AD. The initial compliance 
time for doing the tasks is specified in paragraph (h) of this AD. 
When the applicable temporary revision (TR) has been included in 
general revisions of the TLMC, the general revisions may be inserted 
in the maintenance or inspection program, and the applicable TR may 
be removed, provided the relevant information in the general 
revision is identical to that in the applicable TR.

(i) No Alternative Actions and Intervals

    Except as provided by paragraph (h) of this AD, after the 
maintenance or inspection program has been revised as required by 
paragraph (g) of this AD, no alternative actions (e.g., inspections) 
or intervals may be used unless the actions or intervals are 
approved as an alternative method of compliance (AMOC) in accordance
