[Docket No. FAA-2015-0934; Directorate Identifier 2014-NM-030-AD;
Amendment 39-18287; AD 2015-20-08]
RIN 2120-AA64

Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all
Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G
airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON
20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by
reports of defective fire extinguisher tubes. It was determined the
defects were caused by corrosion. This AD requires repetitive general
visual inspections of the fire extinguisher tubes for cracking and
corrosion, and replacement of any cracked tube with a serviceable tube,
if necessary. We are issuing this AD to detect and correct cracking and
corrosion in the fire extinguisher tubes, which could impact the
capability to extinguish an engine fire, and possibly result in damage
to the airplane and injury to the passengers.

DATES: This AD becomes effective November 12, 2015.

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, FAN JET FALCON SERIES C, D, E, F, and G airplanes;
Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-
D5, 20-E5, and 20-F5 airplanes. The NPRM published in the Federal
Register on May 4, 2015 (80 FR 25254).
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued
Airworthiness Directive 2013-0299, dated December 19, 2013 (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
airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON
20-C5, 20-D5, 20-E5, and 20-F5 airplanes. The MCAI states:

Several defective extinguisher tubes have been reported 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 detected and corrected, could impact the
capability to extinguish an engine fire, possibly resulting in
damage to the aeroplane and injury to the occupants.
For the reason described above, this [EASA] AD requires
repetitive [general visual] inspections [for cracking and corrosion]
of the fire extinguisher tubes and, depending on findings, the
replacement of an affected part with a serviceable part (improved
fire extinguisher tube). It also proposes the replacement of those
tubes with the "old Part Number" (P/N) with a serviceable part
with the new P/N as a terminating action. In addition, this [EASA]
AD prohibits installation of an affected tube on an aeroplane.

You may examine the MCAI in the AD docket on the Internet at http:
//www.regulations.gov/#!documentDetail;D=FAA-2015-0934-0002.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 25254, May 4, 2015)
or on the determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require adopting this AD as proposed, except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (80 FR 25254, May 4, 2015) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (80 FR 25254, May 4, 2015).

Costs of Compliance

We estimate that this AD affects 170 airplanes 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. Based on these figures, we estimate the cost
of this AD on U.S. operators to be $57,800, or $340 per product.
We have received no definitive data that will enable us to provide
cost estimates for the on-condition actions specified in this AD.

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.
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.
