ADDRESSES: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. This proposed AD was prompted by a report of an improper heat treatment process applied during the manufacturing of certain titanium screws. This proposed AD would require replacement of certain titanium screws, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation 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 October 4, 2021. VerDate Sep<11>2014 16:45 Aug 18, 2021 Jkt 253001 Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this proposal.

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. Submissions containing CBI should be sent to Tom Rodriguez, Aerospace Engineer, Large Aircraft Section, International Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; telephone and fax 206–231–3226; email tom.rodriguez@ faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0047, dated February 16, 2021 (EASA AD 2021–0047) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 2000EX airplanes. This proposed AD was prompted by a report of an improper heat treatment process applied during the manufacturing of certain Decomatic titanium screws. The improper heat treatment process led to a hydrogen E:\FR\FM\19AUP1.SGM 19AUP1 46630 Federal Register / Vol. 86, No. 158 / Thursday, August 19, 2021 / Proposed Rules concentration rate in the material of the affected screws that was above the allowable limit. The FAA is proposing this AD to address failure of an affected screw installed in a critical location, possibly resulting in reduced structural integrity of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0047 describes procedures for replacement of certain Decomatic titanium screws (including an inspection of the bore dimension and corrective actions (oversizing or repair)). The EASA AD also restricts installation of certain Decomatic titanium screws. 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. 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 the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2021–0047 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 developed a process to use some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, the FAA proposes to incorporate EASA AD 2021–0047 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021–0047 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 EASA AD 2021–0047 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 EASA AD 2021–0047. Service information required by EASA AD 2021–0047 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0684 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 30 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS * Labor cost Parts cost Up to 90 work-hours × $85 per hour = Up to $7,650 .............. Cost on U.S. operators Cost per product $0 Up to $7,650 ........................... Up to $229,500. * The FAA has received no definitive information regarding cost estimates for these parts. According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators. The FAA does not control warranty coverage for affected operators. As a result, the FAA has included all known costs in the cost estimate. lotter on DSK11XQN23PROD with PROPOSALS1 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 VerDate Sep<11>2014 16:45 Aug 18, 2021 Jkt 253001 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) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 under the criteria of the Regulatory Flexibility Act.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0047, dated February 16, 2021 
(EASA AD 2021-0047) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Dassault Aviation Model FALCON 7X, FALCON 900EX, and FALCON 
2000EX airplanes.
    This proposed AD was prompted by a report of an improper heat 
treatment process applied during the manufacturing of certain Decomatic 
titanium screws. The improper heat treatment process led to a hydrogen

[[Page 46630]]

concentration rate in the material of the affected screws that was 
above the allowable limit. The FAA is proposing this AD to address 
failure of an affected screw installed in a critical location, possibly 
resulting in reduced structural integrity of the airplane. See the MCAI 
for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0047 describes procedures for replacement of certain 
Decomatic titanium screws (including an inspection of the bore 
dimension and corrective actions (oversizing or repair)). The EASA AD 
also restricts installation of certain Decomatic titanium screws. 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.

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 the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2021-0047 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 developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2021-0047 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0047 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 EASA AD 2021-0047 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 EASA AD 2021-
0047. Service information required by EASA AD 2021-0047 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2021-0684 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 30 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                     Estimated Costs for Required Actions *
----------------------------------------------------------------------------------------------------------------
               Labor cost                   Parts cost         Cost per product         Cost on U.S.  operators
----------------------------------------------------------------------------------------------------------------
Up to 90 work-hours x $85 per hour = Up               $0  Up to $7,650..............  Up to $229,500.
 to $7,650.

* The FAA has received no definitive information regarding cost estimates for these parts.

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected operators. The FAA does not control warranty 
coverage for affected operators. As a result, the FAA has included all 
known costs in the cost estimate.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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.

MCAI-2021-00194-T.

[[Page 46631]]

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by October 4, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Dassault Aviation airplanes identified in 
paragraphs (c)(1) through (3) of this AD, certificated in any 
category, as identified in European Union Aviation Safety Agency 
(EASA) AD 2021-0047, dated February 16, 2021 (EASA AD 2021-0047).

    (3) Model FALCON 2000EX airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 51, Standard 
Practices/Structures.

(e) Reason

    This AD was prompted by a report of an improper heat treatment 
process applied during the manufacturing of certain Decomatic 
titanium screws. The FAA is issuing this AD to address failure of an 
affected screw installed in a critical location, possibly resulting 
in reduced structural integrity of the airplane.

(f) Compliance

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

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2021-0047.

(h) Exceptions to EASA AD 2021-0047

    (1) Where EASA AD 2021-0047 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2021-0047 does not apply 
to this AD.
    (3) Where EASA AD 2021-0047 specifies to ``replace each 
serviceable part,'' for this AD that replacement includes an 
inspection of the bore dimension and corrective actions (oversizing 
or repair), as specified in the service information referenced in 
EASA AD 2021-0047.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2021-0047 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.
