Airworthiness Directives; Dassault Model Fan Jet Falcon Series Airplanes; Model Mystere-Falcon 20, 50, 200, and 900 Series Airplanes; and Model Falcon 10, 900EX, and 2000 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Fan Jet Falcon series airplanes; Model Mystere-Falcon 20, 50, 200, and 900 series airplanes; and Model Falcon 10, 900EX, and 2000 series airplanes. This proposal would require a functional test of the passenger oxygen masks, determination of the part number of the installed oxygen mask bags; and corrective action, if necessary. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to ensure that proper plastic bags of the passenger oxygen masks are installed, and that the masks are functioning properly. Improper plastic bags that have cracks or improperly functioning masks could result in insufficient oxygen to passengers in the event of rapid depressurization of the airplane.
DATES: Comments must be received by January 10, 2000.

Discussion
The Direction Generale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified the FAA that an unsafe condition may exist on certain Dassault Model Fan Jet Falcon series airplanes, Model Mystere-Falcon 20, 50, 200, and 900 series airplanes, and Model Falcon 10, 900EX, and 2000 series airplanes; equipped with certain EROS passenger oxygen masks. The DGAC advises that, during a functional test of the passenger oxygen system on a Model Falcon 50
[[Page 68964]]
series airplane, oxygen bags were found cracked at the junction between the bag and the hose.
Investigation revealed that the manufacturer of the oxygen system, EROS, incorporated new plastic bags on certain oxygen masks during 1997 without changing the existing part number of the oxygen masks. These plastic bags do not conform to the existing design standards for oxygen masks installed on the subject airplanes, and may be subject to cracking. This condition, if not corrected, could result in insufficient oxygen to passengers in the event of rapid depressurization of the airplane.
Explanation of Foreign Airworthiness Directives
The DGAC has issued airworthiness directives 1999-270-025(B), dated June 30, 1999 (for Model Fan Jet Falcon series airplanes, Model Mystere-Falcon 20 and 200 series airplanes); 1999-271-026(B), dated June 30, 1999 (for Model Mystere-Falcon 50 and 900 series airplanes, and Model Falcon 900EX series airplanes); 1999-267-010(B), dated June 30, 1999 (for Model Falcon 2000 series airplanes); and 1999-269-024(B), dated June 30, 1999 (for Model Falcon 10 series airplanes); in order to assure the continued airworthiness of these airplanes in France. These French airworthiness directives require a functional test of the passenger masks; determination of the part number of the installed bags; and corrective action, if necessary. The corrective action involves replacing the oxygen mask bags or rendering the passenger seat inoperative. Accomplishment of these actions is intended to adequately address the identified unsafe condition.
FAA's Conclusions
These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. The FAA has examined the findings of the DGAC, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States.
Explanation of Requirements of Proposed Rule
Since an unsafe condition has been identified that is likely to exist or develop on other airplanes of the same type design registered in the United States, the proposed AD would require a functional test of the passenger oxygen masks; determination of the part number of the installed bags; and corrective action, if necessary.
Cost Impact
The FAA estimates that as many as 767 airplanes of U.S. registry may be affected by this proposed AD, that it would take approximately 4 work hours per airplane to accomplish the proposed test and determination, and that the average labor rate is $60 per work hour. Based on these figures, the cost impact of the proposed AD on U.S. operators is estimated to be $184,080, or $240 per airplane.
The cost impact figure discussed above is based on assumptions that no operator has yet accomplished any of the proposed requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted.
Regulatory Impact
The regulations proposed herein would not have substantial direct effects 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. Therefore, in accordance with Executive Order 12612, it is determined that this proposal would not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.
For the reasons discussed above, I certify that 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); and (3) if promulgated, 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. A copy of the draft regulatory evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ``ADDRESSES.''
