14 CFR Part 39

[Docket No. 2001-NM-10-AD; Amendment 39-12489; AD 2001-22-10]
RIN 2120-AA64


Airworthiness Directives; Dassault Model Mystere-Falcon 50, 
Mystere-Falcon 900, and Falcon 900EX Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Dassault Model Mystere-Falcon 50, Mystere-Falcon 900, 
and Falcon 900EX series airplanes, that requires revising the Emergency 
Procedures and Abnormal Procedures sections of the airplane flight 
manual to advise the flightcrew to immediately don oxygen masks in the 
event of significant pressurization or oxygen level changes. The 
actions specified by this AD are intended to prevent incapacitation of 
the flightcrew due to lack of oxygen, which could result in their 
inability to continue to control the airplane. This action is intended 
to address the identified unsafe condition.

DATES: Effective December 3, 2001.

ADDRESSES: Information pertaining to this AD may be examined at the 
Federal Aviation Administration (FAA), Transport Airplane Directorate, 
Rules Docket, 1601 Lind Avenue, SW., Renton, Washington.

FOR FURTHER INFORMATION CONTACT: Tom Rodriguez, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to all Dassault Model Mystere-Falcon 
50, Mystere-Falcon 900, and Falcon 900EX series airplanes was published 
in the Federal Register on April 17, 2001 (66 FR 19727). That action 
proposed to require revising the Emergency Procedures and Abnormal 
Procedures sections of the airplane flight manual to advise the 
flightcrew to immediately don oxygen masks in the event of significant 
pressurization or oxygen level changes.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comment received.

Request To Include Certain Changes to the Airplane Flight Manual 
(AFM)

    The manufacturer reports the issuance of certain AFM changes, which 
correspond to the Figures associated with paragraphs (a) through (f) of 
this AD. The following AFM changes have been issued:

----------------------------------------------------------------------------------------------------------------
                                                  Model/
                 Figure in AD                     Series                 Type of change              Change No.
----------------------------------------------------------------------------------------------------------------
1............................................        MF900   AFM routine revision.................           24
1............................................         MF50   AFM routine revision.................           32
2............................................         MF50   AFM routine revision.................           32
3............................................        MF900   AFM routine revision.................           24
4............................................       F900EX   AFM routine revision.................            6
5............................................         F900C  AFM routine revision.................            2
6............................................        F50EX   AFM routine revision.................            5
----------------------------------------------------------------------------------------------------------------

    The FAA has accordingly revised the final rule to replace Note 1 of 
the proposed AD with new paragraph (g) of the final rule. Paragraph (g) 
specifies that the insertion of those AFM changes (also listed in Table 
1 of this AD) into the AFM are acceptable for compliance with the 
corresponding requirements of this AD.

Conclusion

    After careful review of the available data, including the comment 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule, with the change described 
previously. The FAA has determined that this change will neither 
increase the economic burden on any operator nor increase the scope of 
the AD.

Cost Impact

    The FAA estimates that 137 airplanes of U.S. registry will be 
affected by this AD. It will take approximately 1 work hour per 
airplane to accomplish the actions, at an average labor rate of $60 per 
work hour. Based on these figures, the cost impact of this AD on U.S. 
operators is estimated to be $8,220, or $60 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the requirements of this AD, 
and that no operator would accomplish those actions in the future if 
this AD were not adopted. The cost impact figures discussed in AD 
rulemaking actions represent only the time necessary to perform the 
specific actions actually required by the AD. These figures typically 
do not include incidental costs, such as the time required to gain 
access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not

[[Page 54426]]

have federalism implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and (3) 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 final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
