AD 2017-18-08

We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes. This AD was prompted by reports of ice accretion on the airplane wing due to the failure of certain anti-ice piccolo tubes in the wing outboard slats. This AD requires repetitive inspections of each anti-ice piccolo tube and corrective action 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):

2017-18-08 Dassault Aviation: Amendment 39-19017; Docket No. FAA- 2017-0475; Product Identifier 2016-NM-142-AD.

(a) Effective Date

This AD is effective October 5, 2017.

(b) Affected ADs

None.

[[Page 41325]]

(c) Applicability

This AD applies to Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes, certificated in any category, all serial numbers.

(d) Subject

Air Transport Association (ATA) of America Code 30, Ice and Rain Protection.

(e) Reason

This AD was prompted by reports of ice accretion on the airplane wing due to the failure of certain anti-ice piccolo tubes in the wing outboard slats. We are issuing this AD to detect and correct manufacturing defects in the anti-ice piccolo tubes in the wing outboard slats. This condition could lead to undetected significant ice accretion on a wing, resulting in loss of control of the airplane.

(f) Compliance

Comply with this AD within the compliance times specified, unless already done.

(g) Affected Anti-ice Piccolo Tubes

(1) For the purpose of this AD, an affected anti-ice piccolo tube meets at least one of the conditions specified in paragraphs (g)(1)(i) and (g)(1)(ii) of this AD.
(i) Has part number (P/N) FGFB725102 (left-hand side (LH)) or P/ N FGFB726102 (right-hand side (RH)).
(ii) Is installed on a wing outboard slat having a part number identified in table 1 to paragraph (g)(1)(ii) of this 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 2000 and FALCON 2000EX airplanes. The NPRM published in the Federal Register on May 22, 2017 (82 FR 23163) (``the NPRM''). The NPRM was prompted by reports of ice accretion on the airplane wing due to the failure of certain anti-ice piccolo tubes in the wing outboard slats. The NPRM proposed to require repetitive inspections of each anti-ice piccolo tube and corrective action if necessary. We are issuing this AD to detect and correct manufacturing defects in the anti-ice piccolo tubes in the wing outboard slats. This condition could lead to undetected significant ice accretion on a wing, resulting in loss of control 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 2016-0149, dated July 25, 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 2000 and FALCON 2000EX airplanes. The MCAI states:

Occurrences were reported of ice accretion on the wing, due to failure of the affected anti-ice piccolo tubes Part Number (P/N) FGFB725102. Investigation results indicated that some wing piccolo tubes P/N FGFB725102 could have manufacturing defects in their welded parts, which may have caused the rupture of the tubes, due to fatigue.
This condition, if not detected and corrected, could lead to undetected significant ice accretion on the wing, possibly resulting in loss of control of the aeroplane.
To address this potential unsafe condition, [Dassault Aviation] DA issued Service Bulletin (SB) F2000-431 Revision 1 and SB F2000EX- 391 Revision 1 (hereafter referred to collectively as `the applicable SB' in this [EASA] AD) to provide instructions for endoscopic inspection of the tubes.

[[Page 41324]]

For the reasons described above, this [EASA] AD requires repetitive inspections of each wing outboard slat piccolo tube [for discrepancies, i.e., manufacturing defects, cracking, and loss of material in the welded parts] and, depending on findings, replacement of the piccolo tube(s) [and the outboard slat] with a [new or] serviceable part.

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- 0475.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Change to NPRM

We have added paragraph (j) to this AD to explain that although Dassault Service Bulletin F2000-431, Revision 1, dated June 6, 2016; and Service Bulletin F2000EX-391, Revision 1, dated June 6, 2016; specify to submit a report of crack findings to Dassault, this AD does not require a report. We have redesignated subsequent paragraphs accordingly.

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 for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

Dassault Aviation has issued Service Bulletin F2000-431, Revision 1, dated June 6, 2016; and Service Bulletin F2000EX-391, Revision 1, dated June 6, 2016. The service information describes procedures for endoscopic inspections of the anti-ice piccolo tube on each wing outboard slat, and replacement or re-identification of affected anti- ice piccolo tubes and outboard slats. These documents aredistinct since they apply to different airplane models. 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 348 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs ----------------------------------------------------------------------------------------------------------------
Cost on U.S.

We have received no definitive data that will enable us to provide cost estimates for the on-condition actions specified in this AD.

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 anunsafe 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.
