2021-03601. Airworthiness Directives; Dassault Aviation Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

The FAA is superseding Airworthiness Directive (AD) 2019-03-27, which applied to all Dassault Aviation Model Falcon 10 airplanes. AD 2019-03-27 required repetitive detailed inspections of certain wing anti-ice outboard flexible hoses, and replacement of certain wing anti-ice outboard flexible hoses. This AD continues to require the actions in AD 2019-03-27, and also adds a new life limit for the improved wing anti-ice flexible hose; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a report indicating that certain wing anti-ice outboard flexible hoses were found damaged, likely resulting from the installation process, and the development of an improved wing anti-ice flexible hose. The FAA is issuing this AD to address the unsafe condition on these products.

DATES:

This AD is effective March 31, 2021.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 31, 2021.

SUPPLEMENTARY INFORMATION:

Discussion

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0127, dated June 4, 2020 (EASA AD 2020-0127) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Dassault Aviation Model Falcon 10 airplanes.

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2019-03-27, Amendment 39-19579 (84 FR 7801, March 5, 2019) (AD 2019-03-27). AD 2019-03-27 applied to all Dassault Aviation Model Falcon 10 airplanes. The NPRM published in the Federal Register on November 2, 2020 (85 FR 69269). The NPRM was prompted by a report indicating that certain wing anti-ice outboard flexible hoses were found damaged, likely resulting from the installation process, and the development of an improved wing anti-ice flexible hose. The NPRM proposed to continue to require the actions in AD 2019-03-27, as specified in an EASA AD. The NPRM also proposed to require adding a new life limit for the improved wing anti-ice flexible hose, as specified in EASA AD 2020-0127.

The FAA is issuing this AD to address damaged wing anti-ice outboard flexible hoses, which could lead to a loss of performance of the wing anti-ice protection system that is not annunciated to the pilot, and could result in reduced control of the airplane. See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

The FAA reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM for addressing 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

EASA AD 2020-0127 describes procedures for repetitive detailed inspections of certain wing anti-ice outboard flexible hoses, replacement of certain wing anti-ice outboard flexible hoses, a new life limit for certain wing anti-ice outboard flexible hoses, and optional terminating actions for the repetitive inspections (replacement of all damaged affected wing anti-ice outboard flexible hoses or accomplishing and passing an inspection on an affected wing anti-ice outboard flexible hose after it has accumulated 100 flight cycles since installation on an airplane). This material 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

The FAA estimates that this AD affects 54 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Retained actions from AD 2019-03-27	9 work-hours × $85 per hour = $765	$0	$765	$41,310
New proposed actions	9 work-hours × $85 per hour = $765	316	1,081	58,374

The FAA estimates the following costs to do any necessary on-condition replacements that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need these on-condition replacements:

Estimated Costs of On-Condition actions

Labor cost	Parts cost	Cost per product
9 work-hours × $85 per hour = $765	$316	$1,081

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.

The FAA is 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

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) Will not affect intrastate aviation in Alaska, and

(3) 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.
