SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Dassault Aviation Model 
FAN JET FALCON, and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 
airplanes. The NPRM published in the Federal Register on December 20, 
2016 (81 FR 92747) (``the NPRM''). The NPRM was prompted by reports of 
defective fire extinguisher tubes. The NPRM proposed to require 
replacement of the affected fire extinguisher tubes with improved fire 
extinguisher tubes. We are issuing this AD to prevent fire extinguisher 
failure. Such a failure could result in the inability to extinguish a 
fire in the rear compartment, and possible damage to the airplane and 
injury to the occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0154, dated July 28, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Dassault Aviation 
Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G; and 
Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. The MCAI 
states:

    Several defective extinguisher tubes have been found on certain 
Dassault Aviation Fan Jet Falcon aeroplanes. The results of the 
investigations concluded that these occurrences were caused by 
corrosion.
    This condition, if not corrected, could impact the capability to 
extinguish a fire in the rear compartment of the aeroplane, possibly 
resulting in damage to the aeroplane and injury to the occupants.
    For the reason described above, this [EASA] AD requires the 
replacement of the affected tubes with improved fire extinguisher 
tube. In addition, this [EASA] AD prohibits (re)installation of the 
affected fire extinguisher tubes on an aeroplane.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9500.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Change Compliance Time From Flight Cycles to Flight Hours

    Dassault Aviation noted that paragraph (g) of the proposed AD 
specified a compliance time of 450 flight cycles but the MCAI specified 
a compliance time of 450 flight hours. Dassault Aviation requested that 
we change the compliance time in the proposed AD to specify flight 
hours.
    We acknowledge the commenter's request and agree that we 
inadvertently referred to ``flight cycles'' instead of ``flight hours'' 
in paragraph (g) of the proposed AD. Using flight cycles gives 
operators approximately 3 additional months to comply with the proposed 
action based on the average fleet utilization of these airplanes. 
However, to reduce the compliance time of the proposed AD would 
necessitate (under the provisions of the Administrative Procedure Act) 
reissuing the notice, reopening the period for public comment, and 
eventually issuing a final rule. Those actions would add even more time 
to the rulemaking process and further delay mitigation of the unsafe 
condition. We find that delaying issuance of this final rule is 
inappropriate in light of the identified unsafe condition. Most ADs, 
including this one, permit operators to accomplish the requirements of 
an AD at a time earlier than the specified compliance time. To more 
closely match the EASA specified compliance time without compromising 
safety, we have changed the compliance time in paragraph (g) of this AD 
to ``within 450 flight cycles or 450 flight hours, whichever occurs 
later after the effective date of this AD.''

Request To Change the Compliance Method

    One commenter, Robert Bowers, requested that we change the 
compliance method in the proposed AD to match that specified in AD 
2015-20-08, Amendment 39-18287 (80 FR 60795, October 8, 2015) (``AD 
2015-20-08''). AD 2015-20-08 requires that certain other fire 
extinguisher tubes be inspected every 13 months, until they need to be 
replaced by a new tube. The commenter added that he has inspected two 
Falcon airplanes and finds no reason to replace these fire extinguisher 
tubes at this time.
    We disagree with the commenter's request. The location of the fire 
extinguisher tubes addressed by this AD is more critical from a design 
perspective than that of the fire extinguisher tubes addressed by AD 
2015-20-08. The applicable fire extinguisher tubes must be replaced 
with tubes having an improved design to address the unsafe condition. 
We have not changed this AD in this regard.

Explanation of Change to NPRM

    In the proposed AD, we stated the applicability included ``Dassault 
Aviation Model FAN JET FALCON'' airplanes and inadvertently left out 
``SERIES C, D, E, F, and G'' from the description. For clarity, we have 
revised the applicability to read ``Dassault Aviation Model FAN JET 
FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes . . .'' in 
this final rule. This change does not expand the scope of the final 
rule or add airplanes to the applicability.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Dassault Aviation has issued Service Bulletin F20-790, dated 
September 14,

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
    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.
