AD 2017-25-11

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.

Final rule.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD):

2017-25-11 Dassault Aviation: Amendment 39-19125; Docket No. FAA- 2017-0513; Product Identifier 2016-NM-152-AD.

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

[[Page 59958]]

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 accomplishingthe 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 consistentwith 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 ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- Inspection........................ 5 work-hours x $85 per hour $0 $425 $76,925
= $425. ----------------------------------------------------------------------------------------------------------------

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:

On-Condition Costs ----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product ---------------------------------------------------------------------------------------------------------------- Rework anti-ice tube assembly.............. 2 work-hours x $85 per hour = $170. $1,711 $1,881 ----------------------------------------------------------------------------------------------------------------

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

[[Page 59959]]

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.
