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 FALCON 2000EX airplanes. This AD was prompted
by a quality review of delivered airplanes, which identified a
manufacturing deficiency of some engine air inlet anti-ice ``piccolo''
tubes. This AD requires inspecting each anti-ice ``piccolo'' tube
assembly of certain engine air inlets for discrepancies, and doing
corrective actions if necessary. We are issuing this AD to address the
unsafe condition on these products.

DATES: This AD is effective January 22, 2018.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 22,
2018.

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
FALCON 2000EX airplanes. The NPRM published in the Federal Register on
May 31, 2017 (82 FR 24900) (``the NPRM''). The NPRM was prompted by a
quality review of delivered airplanes, which identified a manufacturing
deficiency of some engine air inlet anti-ice ``piccolo'' tubes. The
NPRM proposed to require inspecting each anti-ice ``piccolo'' tube
assembly of certain engine air inlets for discrepancies, and doing
corrective actions if necessary. We are issuing this AD to detect and
correct discrepancies of each anti-ice ``piccolo'' tube assembly of
certain engine air inlets; this condition could result in reduced
performance of the engine anti-ice protection system, leading to ice
accretion and ingestion into the engines, and possibly resulting in
dual engine power loss and consequent reduced controllability of the
airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2016-0168, dated August 17, 2016 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all Dassault Aviation
Model FALCON 2000EX airplanes. The MCAI states:

A quality review of recently delivered aeroplanes identified a
manufacturing deficiency of some engine air inlet anti-ice
``piccolo'' tubes.
This condition, if not detected and corrected, could lead to
reduced performance of the engine anti-ice protection system, with
consequent ice accretion and ingestion, possibly resulting in dual
engine power loss and reduced control of an aeroplane.
The subsequent investigation demonstrated that, for engines
equipped with an air inlet affected by the manufacturing deficiency,
operating an engine at or above the minimum N1 value applicable for
combined wing and engine anti-ice operations provides efficient
engine anti-ice performance during stand-alone engine anti-ice
operation.
To address this potential unsafe condition, EASA issued EASA AD
2015-0101-E (later revised) to require amendment of the applicable
Aeroplane Flight Manual (AFM) for aeroplanes having engine air
inlets Part Number (P/N) 06ND71600-1 not marked NORDAM Rework Kit
(or ``NRK'') on the associated data plate.
Since that [EASA] AD was issued, Dassault Aviation published
Service Bulletin (SB) F2000EX-384 (later revised), providing
instructions for a one-time inspection and applicable corrective
actions, to recover the full operational capability of the
aeroplanes equipped with affected parts.
For the reasons described above, this [EASA] AD supersedes EASA
AD 2015-0102R1, retaining its requirements, [and] additionally
requires a one-time inspection of each affected anti-ice ``piccolo''
tube assembly and, depending on findings, accomplishment of the
applicable corrective actions. This [EASA] AD also prohibits
installation of an affected part on an aeroplane.

The required actions include a detailed inspection and borescope
inspection for discrepancies, which include determining if the opening
diameter of the anti-ice tube assembly is incorrect or the perforation
holes are blocked by residue. The corrective actions include repair or
rework, if necessary. 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-2017-0513.

Comments

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

Request To Provide Credit for Accomplishing Previous Actions

NetJets Aviation asked that we add Dassault Falcon 2000EX Service
Bulletin F2000EX-384, dated January 27, 2016, as a method of compliance
for accomplishing the actions specified in paragraph (g) of the
proposed AD. NetJets Aviation stated that those actions are done as
specified in Dassault Falcon 2000EX Service Bulletin F2000EX-384,
Revision 1, dated March 1, 2016, which specifies that it does not apply
to airplanes on which the actions in Dassault Falcon 2000EX Service
Bulletin F2000EX-384, dated January 27, 2016, have been done.
We agree with the commenter's request for the reason provided. We
have added paragraph (i) to this AD (and redesignated subsequent
paragraphs accordingly) to provide credit for the actions performed
before the effective date of this AD using Dassault Falcon 2000EX
Service Bulletin F2000EX-384, dated January 27, 2016.

Conclusion

We reviewed the relevant data, considered the comment received, and
determined that air safety and the public interest require adopting
this AD with the change 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

We reviewed Dassault Falcon 2000EX Service Bulletin F2000EX-384,
Revision 1, dated March 1, 2016. This service information describes
procedures for inspecting each anti-ice ``piccolo'' tube assembly of
each engine air inlet for discrepancies, and corrective actions. 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.

Costs of Compliance

We estimate that this AD affects 181 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs

We estimate the following costs to do any necessary rework required
based on the results of the inspection. We have no way of determining
the number of aircraft that might need these corrective actions:

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.
