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
Dassault Aviation Model FAN JET FALCON and FAN JET FALCON SERIES C, D,
E, F, and G airplanes. This AD was prompted by our determination of the
need for a revision to the airplane airworthiness limitations to
introduce changes to the maintenance requirements and airworthiness
limitations. This AD requires revising the maintenance or inspection
program, as applicable, to incorporate a new airworthiness limitations
section. We are issuing this AD to prevent reduced structural integrity
of the airplane.

DATES: This AD becomes effective February 25, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of February 25,
2015.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2014-0626 or in person at the

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 FAN JET FALCON SERIES C, D, E, F, and G airplanes.
The NPRM published in the Federal Register on September 15, 2014 (79 FR
54917).
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2014-0021, dated January 20, 2014 (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 and FAN JET FALCON SERIES C, D, E, F, and G
airplanes. The MCAI states:

The airworthiness limitations and maintenance requirements for
the Fan Jet Falcon type design are included in Dassault Aviation
Falcon 20 (F20) Aircraft Maintenance Manual (AMM) chapter 5-40 and
are approved by the European Aviation Safety Agency (EASA). EASA
issued AD 2008-0221 to require accomplishment of the maintenance
tasks, and implementation of the airworthiness limitations, as
specified in Dassault Aviation F20 AMM chapter 5-40 at revision 13.
Since that [EASA] AD was issued, Dassault Aviation issued F20
AMM chapter 5-40 at revision 15, which introduces new or more
restrictive maintenance requirements and/or airworthiness
limitations.
Dassault Aviation AMM chapter 5-40 revision 15 contains among
other changes the following requirements:
--Specific instructions applicable to F20GF (serial number 397);
--Check of overpressure tightness on pressurization control
regulating valves;
--Check of overpressure relief valve vacuum supply lines.
A new document reference number which comes with DGT 131028
revision 15 is replacing DMD11755.
The maintenance tasks and airworthiness limitations, as
specified in the F20 AMM chapter 5-40, have been identified as
mandatory actions for continued airworthiness of the Fan Jet Falcon
type design. Failure to comply with AMM chapter 5-40 at revision 15
might constitute an unsafe condition.
For the reasons described above, this [EASA] AD requires
implementation of the maintenance tasks and airworthiness
limitations, as specified in Dassault Aviation F20 AMM chapter 5-40
at revision 15.

The unsafe condition is reduced structural integrity of the
airplane. You may examine the MCAI in the AD docket on the Internet at
http://www.regulations.gov/#!documentDetail;D=FAA-2014-0626-0002.

Comments

We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 54917, September
15, 2014) 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 (79 FR 54917, September 15, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 54917, September 15, 2014).

Costs of Compliance

We estimate that this AD affects 168 airplanes of U.S. registry.
We also estimate that it would take about 1 work-hour 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 $14,280, or $85 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.

Examining the AD Docket

You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2014-0626; or in person at
the Docket Management Facility between 9 a.m. and 5 p.m., Monday through
Friday, except Federal holidays. The AD docket contains this AD, the
regulatory evaluation, any comments received, and other information.
