Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), 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 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 proposed AD 
would require inspecting the network interface installation between the 
IMS and the CES, and disconnecting the installation, if necessary. We 
are proposing 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: We must receive comments on this proposed AD by February 29, 
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.

Discussion

    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 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:/

8431.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information, which 
describes procedures for an inspection of the network interface 
installation between the IMS and CES and disconnection of the 
installation.
     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.

FAA's Determination and Requirements of This Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 77 airplanes of U.S. 
registry.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $6,545, or $85 per 
product.
    In addition, we estimate that any necessary follow-on action would 
take 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 proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
