Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all
Dassault Aviation Model FALCON 2000 airplanes. This proposed AD was
prompted by the manufacturer revising the airplane maintenance manual
(AMM) maintenance requirements and airworthiness limitations. This
proposed AD would require revising the maintenance or inspection
program, as applicable, to incorporate new maintenance requirements and
airworthiness limitations. We are proposing this AD to address the
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by June 14, 2018.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2017-0236, dated November 30, 2017 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
"the MCAI"), to correct an unsafe condition for all Dassault Aviation
Model FALCON 2000 airplanes. The MCAI states:

The airworthiness limitations for Dassault Falcon 2000
aeroplanes, which are approved by EASA, are currently defined and
published in Aircraft Maintenance Manual (AMM) Airworthiness
Limitations Section (ALS) Chapter 5-40. These instructions have been
identified as mandatory for continued airworthiness.

Failure to accomplish these instructions could result in an
unsafe condition [i.e., reduced controllability of the airplane].

EASA previously issued [EASA] AD 2012-0156 [which corresponds to
FAA AD 2014-03-12 Amendment 39-17749 (79 FR 11693, March 3, 2014)
("AD 2014-03-12")], requiring the actions described in Dassault
Falcon 2000 AMM Chapter 5-40 (DGT 113876) at Revision 17.

Since that AD was issued, Dassault published Revision 18 of
Dassault Falcon 2000 AMM Chapter 5-40 (DGT 113876), containing new
and/or more restrictive maintenance tasks and introducing (among
other changes) the Corrosion Prevention and Control Programme.

For the reason described above, this [EASA] AD retains the
requirements of EASA AD 2012-0156, which is superseded, and requires
accomplishment of the actions specified in Dassault Falcon 2000 AMM
Chapter 5-40 (DGT 113876) at Revision 18 * * *.

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-2018-0306.

Relationship Between Proposed AD and AD 2014-03-12

This NPRM would not supersede AD 2014-03-12. Rather, we have
determined that a stand-alone AD would be more appropriate to address
the changes in the MCAI. This NPRM would require revising the
maintenance or inspection program to incorporate the new maintenance
requirements and airworthiness limitations. Accomplishment of the
proposed actions would then terminate all of the requirements of AD
2014-03-12.

Related Service Information Under 1 CFR Part 51

Dassault Aviation has issued Chapter 5-40, Airworthiness
Limitations, Revision 19, dated November 2017, of Chapter 5,
Maintenance Planning Document, of the Dassault Falcon 2000 Maintenance
Manual. This service information describes instructions applicable to
airworthiness and safe life limitations. This service information is
reasonably available because the interested parties have access to it
through their normal course of business or by the means identified in
the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type designs.

This AD requires revisions to certain operator maintenance
documents. Compliance with these revisions are required by 14 CFR
91.403(c). For airplanes that have been previously modified, altered,
or repaired in the areas addressed by this proposed AD, the operator
may not be able to accomplish the actions described in the revisions.
In this situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according to
paragraph (j)(1) of this proposed AD. The request should include a
description of changes to the required actions that will ensure the
continued damage tolerance of the affected structure.

Difference Between the MCAI and This Proposed AD

The MCAI specifies that if there are findings from the
airworthiness limitations section (ALS) inspection tasks, corrective
actions must be accomplished in accordance with Dassault Aviation
maintenance documentation. However, this proposed AD does not include
that requirement. Operators of U.S.-registered airplanes are required
by general airworthiness and operational regulations to perform
maintenance using methods that are acceptable to the FAA. We consider
those methods to be adequate to address any corrective actions
necessitated by the findings of ALS inspections required by this
proposed AD.

Costs of Compliance

We estimate that this proposed AD affects 195 airplanes of U.S.
registry.

We estimate the following costs to comply with this proposed AD:

We have determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although this
figure may vary from operator to operator. In the past, we have
estimated that this action takes 1 work-hour per airplane. Since
operators incorporate maintenance or inspection program changes for
their affected fleet(s), we have determined that a per-operator
estimate is more accurate than a per-airplane estimate. Therefore, we
estimate the total cost per operator to be $7,650 (90 work-hours x $85
per work-hour).

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 proposed 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:

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.
