AD 2016-19-13

We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. This AD was prompted by a report of an in-flight lightning strike to the WHELEN anti- collision light located on the top of the vertical fin tip that caused severe damage and resulted in the loss of some airplane functions. This AD requires modification of the anti-collision light bonding. We are issuing this AD to prevent loss of electrical power and essential airplane functions, and possible reduced control of the airplane.

Final rule.

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The SNPRM published in the Federal Register on June 17, 2016 (81 FR 39597) (``the SNPRM''). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on September 24, 2015 (80 FR 57545) (``the NPRM''). The NPRM proposed to require modification of the anti- collision light bonding. The NPRM was prompted by a report of an in- flight lightning strike to the WHELEN anti-collision light located on the top of the vertical fin tip that caused severe damage and induced the loss of some airplane functions. The SNPRM proposed to clarify the applicability. We are issuing this AD to prevent loss of electrical power and essential airplane functions, and possible reduced 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 2015-0006, dated January 15, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for certain Dassault Aviation Model MYSTERE-FALCON 50, MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and FALCON 2000EX airplanes. The MCAI states:

An occurrence was reported where a Falcon 2000 aeroplane experienced an in-flight lightning strike, which caused severe damage and induced the loss of some aeroplane functions. The investigation results revealed that the entering point of the lightning was at the WHELEN anti-collision light located on the top of the vertical fin tip.
When the lightning strike hit the anti-collision light, an electric arc occurred between the aeroplane structure and the anti- collision light andcreated a conductive path by which the lightning current entered inside the aeroplane. Further analysis has determined that the electrical bonding between the WHELEN anti- collision light, Part Number (P/N) 01-0790044-09, and the fin tip fairing or the No. 2 engine air intake cover is insufficient to withstand a lightning strike.
In case of severe lightning, this condition, if not corrected, could lead to an unsafe condition (loss of electrical power and/or of essential functions) possibly resulting in reduced control of the aeroplane.
To address this potential unsafe condition, Dassault Aviation developed a modification (mod) to improve the WHELEN anti-collision light bonding when the anti-collision light is located on top of the vertical fin tip or on No. 2 engine air intake cover, and issued several Service Bulletins (SB) to modify all affected aeroplanes in service.
For the reasons described above, this [EASA] AD requires modification of the anti-collision light bonding.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-2015- 3629.

Comments

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

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

Related Service Information Under 1 CFR Part 51

We reviewed the following service information.
Dassault Service Bulletin F50-481, Revision 1 (also referred to as 481-R1), dated January 26, 2015.
Dassault Service Bulletin F900-372,Revision 1 (also referred to as 372-R1), dated January 26, 2015.
Dassault Service Bulletin F900-378, Revision 1 (also referred to as 378-R1), dated January 26, 2015.
Dassault Service Bulletin F900EX-285, Revision 1 (also referred to as 285-R1), dated January 26, 2015.

[[Page 71587]]

Dassault Service Bulletin F900EX-305, Revision 1 (also referred to as 305-R1), dated January 26, 2015.
Dassault Service Bulletin F2000-337, Revision 1 (also referred to as 337-R1), dated January 26, 2015.
Dassault Service Bulletin F2000EX-108, Revision 1 (also referred to as 108-R1), dated January 26, 2015.
The service information describes procedures for modifying the anti-collision light bonding. These documents are distinct since they apply to different airplane models in different configurations. 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 778 airplanes of U.S. registry.
We also estimate that it would take about 12 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $801 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $1,416,738, or $1,821 per product.

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.

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.
