Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Dassault Aviation Model FALCON 7X airplanes. This AD requires revising 
the aircraft flight manual (AFM); performing operational tests of the 
oxygen mask oxygen assembly; and replacing affected stowage boxes, 
which terminates the AFM revision and operational tests. This AD was 
prompted by failure of the flight crew oxygen supply due to a 
potentially defective flight crew mask oxygen assembly. We are issuing 
this AD to prevent failure to supply oxygen upon demand to the flight 
crew in flight in ``100%'' and ``Emergency'' modes, which, in an 
emergency, may result in incapacitation of the flight crew.

DATES: This AD becomes effective May 6, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of May 6, 2013.
    We must receive comments on this AD by June 3, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued 
emergency EASA Airworthiness Directive 2013-0059-E, dated March 8, 2013 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During an aeroplane delivery flight test, the flight crew oxygen 
supply failed. The technical investigations carried out by the 
flight crew oxygen mask and stowage box manufacturer identified 
potentially defective flight crew mask oxygen assembly part number 
(P/N) MSE30-005-3-8 including stowage box P/N CSD 30-005-3-8.
    This condition, if not detected and corrected, may cause failure 
to supply oxygen upon demand to the flight crew in flight in 
``100%'' and ``Emergency'' modes which, in case of an emergency, may 
result in incapacitation of the flight crew.
    To address this potential unsafe condition, Dassault Aviation 
(DA) issued Service Bulletin (SB) F7X-241, containing instructions 
to identify and replace the affected flight crew oxygen masks and 
stowage boxes.
    For the reasons described above, this [EASA] AD requires 
[revision of the aircraft flight manual and] accomplishment of 
operational tests of each flight crew oxygen mask and replacement of 
the affected stowage boxes with serviceable parts. Replacement 
constitutes terminating action for the [AFM revision and] repetitive 
operational tests.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Dassault Aviation has issued Mandatory Service Bulletin 7X-241, 
dated March 7, 2013. The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI.

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 the same 
type design.

Explanation of Compliance Times

    The MCAI requires revising the AFM before further flight. This AD, 
however, provides a compliance time of 14 days, which will provide an 
adequate level of safety without unnecessarily grounding airplanes.
    Replacing affected oxygen mask stowage boxes terminates the 
requirement to revise the AFM. The MCAI requires replacing the stowage 
boxes within a specified time after the effective date. This AD, 
however, requires compliance within the specified time after the AFM 
revision to avoid potentially conflicting compliance times that could 
require operators to replace the stowage box before revising the AFM.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
failure to supply oxygen upon demand to the flight crew in flight in 
``100%'' and ``Emergency'' modes in an emergency may result in 
incapacitation of the flight crew. Therefore, we determined that notice 
and opportunity for public comment before issuing this AD are 
impracticable and that good cause exists for making this amendment 
effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2013-0306; Directorate 
Identifier 2013-NM-049-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD will affect 9 products of U.S. registry. 
We also estimate that it will take about 4 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $0 per product. 
Where the service information lists required parts costs that are 
covered under warranty, we have assumed that there will be no charge 
for these parts. As we do not control warranty coverage for affected 
parties, some parties may incur costs higher than estimated here. Based 
on these figures, we estimate the cost of this AD to the U.S. operators 
to be up to $3,060, or $340 per product.

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.

[[Page 23460]]

    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
