Final rule; request for comments.
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.
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.

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.
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.
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.Start Printed 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.Start List of Subjects
