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 reports of aileron and rudder control cables that may 
have tensions that are beyond allowable limits. This AD requires a 
revision to the maintenance or inspection program to incorporate 
certification maintenance requirement tasks that introduce functional 
tests of the control cable tension. We are issuing this AD to address 
the unsafe condition on these products.

DATES: This AD is effective August 31, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 31, 
2017.

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 November 7, 2016 (81 FR 78080). The NPRM was 
prompted by reports of aileron and rudder control cables that may have 
tensions that are beyond allowable limits. The NPRM proposed to require 
revising the maintenance or inspection program to incorporate 
certification maintenance requirement tasks that introduce functional 
tests of the control cable tension. 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.
    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 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 AD requires 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 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 AD. The request 
should include a description of changes to the required actions that 
will ensure the continued operational safety of the airplane.

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 Reference the Latest Time Limits/Maintenance Checks (TLMC) 
General Revision Instead of the Temporary Revision (TR)

    Bombardier, Inc., and KACALP Flight Operations requested that 
paragraph (g)

[[Page 34842]]

of this AD, reference the latest TLMC general revision for each 
affected Bombardier, Inc. airplane model instead of the TR to each 
applicable TLMC. The commenters noted that the TLMC TRs are no longer 
available on Bombardier's Web site, as they have been incorporated into 
the TLMC Revision. The commenters indicated that the Canadian 
Airworthiness Directive CF-2016-06R1, dated July 25, 2016, references 
these TLMC Revisions, as should the FAA AD.
    We do not agree to delay issuance of this AD to reference the 
latest TLMC general revision. Paragraph (g) of this AD states that when 
the applicable TR has been included in a general revision of the TLMC, 
the general revision may be inserted in the maintenance or inspection 
program and the applicable TR may be removed. The TR for each affected 
Bombardier, Inc. airplane model TLMC is available on the Internet at 
http://www.regulations.gov. The service information can be found by 
searching for and locating Docket No. FAA-2016-9304. We have, however, 
added note 1 to paragraph (g) of this AD to identify the TLMC task 
number and airplane maintenance manual (AMM) manual number that 
corresponds to each TR.

Request To Revise Compliance Time

    Bombardier, Inc., and KACALP Flight Operations requested that we 
revise paragraphs (h)(1) and (h)(2) of the proposed AD to remove the 
later alternative compliance time ``within 30 months since the date of 
issuance of the original Canadian airworthiness certificate or the date 
of issuance of the original Canadian export certificate of 
airworthiness.'' The commenters noted that some airplanes have already 
exceeded, or will soon exceed, this threshold and would be immediately 
grounded by the proposed AD.
    We agree with the request. We have revised the compliance time in 
paragraphs (h)(1) and (h)(2) of this AD to within 15 months after the 
effective date of this AD. We have determined that this change will not 
affect flight safety or the calculated risk assessment, and will not 
impose any additional burden on any operator.

Request To Remove Paragraph (h)(3) of This AD

    Bombardier, Inc., requested that paragraph (h)(3) of this AD be 
removed. Bombardier, Inc., noted that the Canadian AD CF-2016-06R1, 
dated July 25, 2016, did not give any actions for the aircraft in 
paragraph (h) of this AD. Bombardier, Inc. indicated that for these 
aircraft, inserting the certification maintenance requirements (CMR) 
task into the scheduled maintenance or inspection program, as described 
in paragraph (g) of this AD, and following the specified task interval 
in the TLMC is sufficient.
    We do not agree to remove paragraph (h)(3) of this AD. Paragraph 
(h) of this AD provides the compliance times for the initial actions 
that are incorporated into the maintenance or inspection program, as 
specified in paragraph (g) of this AD. These compliance times are 
necessary to provide a starting point for the inspections. The FAA 
finds it necessary to specify initial compliance times for maintenance 
actions in ADs because this information is not normally included in the 
design approval holder's (DAH) service information. The airplanes 
identified in paragraph (h)(3) of this AD are also identified in 
paragraph (g) of this AD. We have not changed this AD in this regard.

Request To Include CMR Tasks and Procedures

    KACALP Flight Operations requested that we revise paragraph (i) of 
the proposed AD to include the inspection intervals and procedural 
instructions in the referenced TR of the Bombardier Model BD-700-1A10 
and BD-700-1A11 airplanes' CMR. KACALP Flight Operations then suggested 
that these instructions in paragraph (i) of the proposed AD be 
referenced in the TLMC and AMM as a way to ensure compliance with each 
subsequent revision to the TLMC and AMM. KACALP Flight Operations 
stated that owner/operators are not obligated by regulation to own a 
technical subscription from the original equipment manufacturer (OEM), 
but that most recipients of a Bombardier Technical Library own a 
digital subscription. Bombardier, Inc. automatically removes the TRs 
and updates the standard issue to the TLMC and AMM without immediate 
notice. Bombardier stated that nothing would trigger either the OEM or 
the subscriber to look for changes to an interval or procedure; 
therefore, these owner/operators would not know if there is a change to 
an interval or procedure. KACALP Flight Operations suggested that the 
FAA could mandate a maintenance record requirement specifically for 
aircraft inspection programs.
    We find that clarification is necessary. When possible, we rely on 
the DAH to provide accomplishment instructions in their service 
information; referencing this information provides for brevity in ADs 
and minimizes errors in ADs. Owners/operators are responsible for 
compliance with ADs, as well as the proper maintenance and safe 
operation of their airplanes, by adhering to the actions specified in 
the TLMC and AMM. Therefore, we have not changed paragraph (i) of this 
AD.
    We also do not agree to mandate a maintenance record requirement 
specifically for aircraft inspection programs. At this time, the FAA 
does not require manufacturers to reference ADs within their service 
information. We have not changed this AD in this regard.

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.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Bombardier, Inc. service information:
    <bullet> TR 5-2-10, dated November 24, 2015, to Section 5-10-40, of 
Bombardier Global Express XRS BD-700 Time Limits/Maintenance Checks.
    <bullet> TR 5-2-15, dated November 24, 2015, to Section 5-10-40, of 
Bombardier Global 6000 GL 6000 Time Limits/Maintenance Checks.
    <bullet> TR 5-2-15, dated November 24, 2015, to Section 5-10-40, of 
Bombardier Global 5000 GL 5000 Featuring Global Vision Flight Deck--
Time Limits/Maintenance Checks.
    <bullet> TR 5-2-16, dated November 24, 2015, to Section 5-10-40, of 
Bombardier Global 5000 BD-700 Time Limits/Maintenance Checks.
    <bullet> TR 5-2-47, dated November 24, 2015, to 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. These documents are distinct since they apply to 
different airplane models. This service information is reasonably 
available because the interested parties have access to it through 
their normal

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.
