Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000EX airplanes. This proposed 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 proposed AD would require inspecting each anti-ice “piccolo” tube assembly of certain engine air inlets for discrepancies, and doing corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
We must receive comments on this proposed AD by July 17, 2017.
You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

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.Start Printed Page 24901
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.
Other Related Rulemaking
On June 19, 2015, we issued AD 2015-13-08, Amendment 39-18195 (80 FR 37150, June 30, 2015) (“AD 2015-13-08”), applicable to all Dassault Aviation Model FALCON 2000EX airplanes. That AD requires revising the airplane flight manual to include a procedure for addressing minimum fan speed rotation (N1) values during stand-alone engine anti-ice system operation for engines equipped with certain air inlets. That AD was prompted by a quality review of certain delivered airplanes, which identified a manufacturing deficiency of some engine air inlet anti-ice “piccolo” tubes. The actions required by that AD are intended to detect and correct reduced performance of the engine anti-ice protection system, leading to ice accretion and ingestion into the engines, which could result in dual engine power loss and consequent reduced controllability of the airplane.
Actions Since Issuance of AD 2015-13-08
This NPRM would not supersede AD 2015-13-08. Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This NPRM would require inspections and corrective actions of the anti-ice “piccolo” tube assembly of the engine air inlet. Accomplishment of the actions specified in paragraph (g) of this proposed AD would then terminate all of the requirements of AD 2015-13-08.
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.
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 design.
Costs of Compliance
We estimate that this proposed AD affects 181 airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
|Action||Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Inspection||5 work-hours × $85 per hour = $425||$0||$425||$76,925|
We estimate the following costs to do any necessary rework that would be required based on the results of the proposed inspection. We have no way of determining the number of aircraft that might need these corrective actions:
|Action||Labor cost||Parts cost||Cost per product|
|Rework anti-ice tube assembly||2 work-hours × $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 Start Printed Page 24902safety 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.
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.

This AD applies to all Dassault Aviation Model FALCON 2000EX airplanes, certificated in any category.
Air Transport Association (ATA) of America Code 30, Ice and Rain Protection.
This AD was prompted by a quality review of certain delivered airplanes, which identified a manufacturing deficiency of certain engine air inlet anti-ice “piccolo” tubes. 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.
