14 CFR Part 39

[Docket No. FAA-2015-8431; Directorate Identifier 2015-NM-128-AD; 
Amendment 39-18517; AD 2016-10-06]

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 a determination that the network interface installed 
between the Information Management System (IMS) 6000 unit and the Cabin 
Entertainment System (CES) network could affect the Aircraft Control 
Domain (ACD), and result in the transmission of misleading navigational 
information to the flightcrew. This AD requires inspecting the network 
interface installation between the IMS and the CES, and disconnecting 
the installation, if necessary. We are issuing this AD to prevent the 
transmission of misleading navigational information, which could 
adversely affect the ability of the flightcrew to maintain the safe 
flight and landing of the airplane.

DATES: This AD is effective June 23, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 23, 
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 January 13, 2016 (81 FR 1568) (``the NPRM''). The 
NPRM was prompted by a determination that the network interface 
installed between the IMS 6000 unit and the CES network could affect 
the ACD, and result in the transmission of misleading navigational 
information to the flightcrew. The NPRM proposed to require inspecting 
the network interface installation between the IMS and the CES, and 
disconnecting the installation, if necessary. We are issuing this AD to 
prevent the transmission of misleading navigational information, which 
could adversely affect the ability of the flightcrew to maintain the 
safe flight and landing of the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-19, dated July 20, 2015 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition

[[Page 31496]]

for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 
airplanes. The MCAI states:

    It was discovered that on certain aeroplanes, the network 
interface installed between the Information Management System (IMS) 
6000 unit and the Cabin Entertainment System (CES) network may 
affect the Aircraft Control Domain (ACD). This could potentially 
compromise the operational integrity of the avionics system and 
result in misleading navigational information to the flight crew. 
Misleading navigational information could have adverse effects on 
the safe operation of the aeroplane.
    This [Canadian] AD mandates the [general visual] inspection [to 
determine if pins are present at positions 25, 27, 48, and 50] and 
disconnection, as required, of the network interface installation 
between the IMS and the CES.

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-2015-
8431.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
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.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information, which 
describes procedures for inspecting the network interface installation 
between the IMS and the CES, and disconnecting the installation, if 
necessary.
     Service Bulletin 700-46-5005, Revision 02, dated June 18, 
2015 (for Model BD-700-1A11 airplanes).
     Service Bulletin 700-46-6005, Revision 02, dated June 18, 
2015 (for Model BD-700-1A10 airplanes).
    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 77 airplanes of U.S. registry.
    We also estimate that it takes about 1 work-hour 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 $6,545, or $85 per product.
    In addition, we estimate that any necessary follow-on action takes 
about 3 work-hours, for a cost of $255 per product. We have no way of 
determining the number of aircraft that might need this action.
    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.
