Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to supersede Airworthiness Directive (AD) 2019-03-27, which applies to all Dassault Aviation Model Falcon 10 airplanes. AD 2019-03-27 requires repetitive detailed inspections of certain wing anti-ice outboard flexible hoses, and replacement of certain wing anti-ice outboard flexible hoses. Since the FAA issued AD 2019-03-27, an improved wing anti-ice flexible hose has been developed. This proposed AD would continue to require the actions in AD 2019-03-27, and would add a new life limit for the improved wing anti-ice flexible hose, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.

DATES:

The FAA must receive comments on this proposed AD by December 17, 2020.

SUPPLEMENTARY INFORMATION:

Comments Invited

The FAA invites you to participate in this rulemaking by submitting written comments, data, or views about this proposal. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2020-0977; Project Identifier MCAI-2020-01106-T” at the beginning of your comments.

Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider all comments received by the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this NPRM because of those comments.

Confidential Business Information

CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as “PROPIN.” The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM.

Discussion

The FAA issued AD 2019-03-27, Amendment 39-19579 (84 FR 7801, March 5, 2019) (“AD 2019-03-27”), which applies to all Dassault Aviation Model Falcon 10 airplanes. AD 2019-03-27 requires repetitive detailed inspections of certain wing anti-ice outboard flexible hoses, and replacement of certain wing anti-ice outboard flexible hoses. The FAA issued AD 2019-03-27 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.

Actions Since AD 2019-03-27 Was Issued

Since the FAA issued AD 2019-03-27, an improved wing anti-ice flexible hose has been developed which has the same life limit as other wing anti-ice outboard flexible hoses. The FAA has determined that the improved wing anti-ice flexible hose may be installed on airplanes and that a life limit for the improved wing anti-ice flexible hose must be implemented.

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. EASA AD 2020-0127 supersedes EASA AD 2019-0040-E, dated February 21, 2019 (which corresponds to AD 2019-03-27).

This proposed 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 proposing 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.

Explanation of Retained Requirements

Although this proposed AD does not explicitly restate the requirements of AD 2019-03-27, this proposed AD would retain all of the requirements of AD 2019-03-27. Those requirements are referenced in EASA AD 2020-0127, which, in turn, is referenced in paragraph (g) of this proposed AD.

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.Start Printed Page 69271

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 the FAA's bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the FAA 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.

Proposed AD Requirements

This proposed AD would require accomplishing the actions specified in EASA AD 2020-0127 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD.

Explanation of Required Compliance Information

In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2020-0127 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2020-0127 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in the EASA AD. Service information specified in EASA AD 2020-0127 that is required for compliance with EASA AD 2020-0127 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0977 after the FAA final rule is published.

Costs of Compliance

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

Estimated Costs for Required Actions

ActionLabor costParts costCost per productCost on U.S. operators
Retained actions from AD 2019-03-279 work-hours × $85 per hour = $765$0$765$41,310
New proposed actions9 work-hours × $85 per hour = $7653161,08158,374

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 costParts costCost 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

The FAA 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) 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.
