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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) 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. This AD was
prompted by reports of a manufacturing defect in the charge indicator
on fire extinguisher bottles. This AD requires repetitive weighing of
fire extinguisher bottles having a certain part number, and eventual
replacement of those bottles to terminate the repetitive weighing. We
are issuing this AD to detect and correct a dormant failure in the fire
suppression system, which could result in the inability to put out a
fire in an engine, auxiliary power unit, or rear compartment.

DATES: This AD becomes effective October 20, 2014.

The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of October 20, 2014.

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 21, 2013 (78 FR 29669). The NPRM was prompted by
reports of a manufacturing defect in the charge indicator on fire
extinguisher bottles. The NPRM proposed to require repetitive weighing
of fire extinguisher bottles having a certain part number, and eventual
replacement of those bottles to terminate the repetitive weighing. We
are issuing this AD to detect and correct a dormant failure in the fire
suppression system, which could result in the inability to put out a
fire in an engine, auxiliary power unit, or rear compartment.

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2012-0189, dated September 24, 2012 (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:

A manufacturing defect of the charge indicator of fire
extinguisher bottles has been reported on Dassault Aviation Fan Jet
Falcon and Myst[egrave]re-Falcon 20 series aeroplanes.

The results of the investigations concluded that this defect may
lead to corrosion of the charge indicator, causing improper
indication of loss of pressure inside the bottle. In addition, the
Part Numbers (P/N) of the fire extinguishers and batch numbers of
the affected charge indicators have been identified.

This condition, if not detected and corrected, could constitute
a dormant failure that might impact the capability to extinguish a
fire, either in an engine or the Auxiliary Power Unit (APU) or the
rear compartment, possibly resulting in damage to the aeroplane and
injury to the occupants.

For the reasons described above, this [EASA] AD requires
repetitive weighing of the affected fire extinguishers bottles and,
ultimately replacement of the affected bottles with serviceable
bottles. In addition, this [EASA] AD prohibits installation of an
affected fire extinguisher bottle.

You may examine the MCAI in the AD docket on the Internet at
http://www.regulations.gov/#!documentDetail;D=FAA-2013-0423-0003.

Comments


We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (78 FR 29669, May 21,
2013) or on the determination of the cost to the public.

"Contacting the Manufacturer'' Paragraph in This AD


Since late 2006, we have included a standard paragraph titled
"Airworthy Product'' in all MCAI ADs in which the FAA develops an AD
based on a foreign authority's AD.

We have become aware that some operators have misunderstood or
misinterpreted the Airworthy Product paragraph to allow the owner/
operator to use messages provided by the manufacturer as approval of
deviations during the accomplishment of an AD-mandated action. The
Airworthy Product paragraph does not approve messages or other
information provided by the manufacturer for deviations to the
requirements of the AD-mandated actions. The Airworthy Product
paragraph only addresses the requirement to contact the manufacturer
for corrective actions for the identified unsafe condition and does not
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request
the approval for an alternative method of compliance to the AD-required
actions using the procedures found in 14 CFR 39.19.

To address this misunderstanding and misinterpretation of the
Airworthy Product paragraph, we have changed the paragraph and retitled
it "Contacting the Manufacturer.'' This paragraph now clarifies that
for any requirement in this AD to obtain corrective actions from a
manufacturer, the actions must be accomplished using a method approved
by the FAA, EASA, or Dassault Aviation's EASA Design Organization
Approval (DOA).

The Contacting the Manufacturer paragraph also clarifies that, if
approved by the DOA, the approval must include the DOA-authorized
signature. The DOA signature indicates that the data and information
contained in the document are EASA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer
that do not contain the DOA-authorized signature approval are not EASA-
approved, unless EASA directly approves the manufacturer's message or
other information.

This clarification does not remove flexibility previously afforded
by the Airworthy Product paragraph. Consistent with long-standing FAA
policy, such flexibility was never intended for required actions. This
is also consistent with the recommendation of the Airworthiness
Directive Implementation Aviation Rulemaking Committee to increase
flexibility in complying with ADs by identifying those actions in
manufacturers' service instructions that are "Required for
Compliance'' with ADs. We continue to work with manufacturers to
implement this recommendation. But once we determine that an action is
required, any deviation from the requirement must be approved as an
alternative method of compliance.

We also have decided not to include a generic reference to either
the "delegated agent'' or "design approval holder (DAH) with State of
Design Authority design organization approval,'' but instead we have
provided the specific delegation approval granted by the State of
Design Authority for the DAH.

Explanation of Changes to This AD


Paragraphs (h)(2), (h)(2)(i), (h)(2)(iii), (h)(2)(iv), (i), (i)(1),
(i)(3), (i)(4), (j)(1), (j)(3), and (j)(4) of this AD were revised to
state that required actions must be done in accordance with a method
approved by the Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA; or the EASA; or Airbus's EASA DOA. The
service information previously referenced in those paragraphs is now
referenced as guidance material in notes to the applicable paragraphs.

Conclusion


We reviewed the available data 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 (78 FR 29669, May 21, 2013) for correcting the unsafe condition;
and

Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 29669, May 21, 2013).

We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.

Costs of Compliance


We estimate that this AD affects 185 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. Required parts will cost about $6,400 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be up to $1,246,900, or $6,740 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.

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.
