RIN 2120-AA64


Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2019-23-03, which applies to certain Dassault Aviation Model FALCON 
900EX airplanes. AD 2019-23-03 requires revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive maintenance requirements and/or airworthiness 
limitations. Since the FAA issued AD 2019-23-03, the FAA has determined 
that new or more restrictive airworthiness limitations are necessary. 
This proposed AD would continue to require those maintenance or 
inspection program revisions, and would also require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate additional new or more restrictive airworthiness 
limitations, 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 September 
17, 2020.

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments 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-
2020-0677; Product Identifier 2020-NM-099-AD'' 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. Submissions containing CBI should be sent to the 
person identified in the FOR FURTHER INFORMATION CONTACT section. Any 
commentary that the FAA receives which is not

[[Page 46561]]

specifically designated as CBI will be placed in the public docket for 
this rulemaking.

Discussion

    The FAA issued AD 2019-23-03, Amendment 39-19796 (84 FR 67171, 
December 9, 2019) (``AD 2019-23-03''), for certain Dassault Aviation 
Model FALCON 900EX airplanes. AD 2019-23-03 requires revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. The FAA 
issued AD 2019-23-03 to address, among other things, fatigue cracking 
and damage in principal structural elements; such fatigue cracking and 
damage could result in reduced structural integrity of the airplane.
    AD 2019-23-03 specifies that accomplishing the actions required by 
paragraph (g) or (i) of that AD terminates the requirements of 
paragraph (g)(1) of AD 2010-26-05, Amendment 39-16544 (75 FR 79952, 
December 21, 2010) for Dassault Aviation Model 900EX airplanes, serial 
number (S/N) 97 and S/Ns 120 and higher.

Actions Since AD 2019-23-03 Was Issued

    Since the FAA issued AD 2019-23-03, the FAA has determined that new 
or more restrictive airworthiness limitations are necessary.
    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0117, dated May 20, 2020 
(``EASA AD 2020-0117'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Dassault Aviation Model FALCON 900EX airplanes. 
EASA AD 2020-0117 superseded EASA AD 2019-0134 (which corresponds to 
FAA AD 2019-23-03). Airplanes with an original airworthiness 
certificate or original export certificate of airworthiness issued 
after October 2, 2019 must comply with the airworthiness limitations 
specified as part of the approved type design and referenced on the 
type certificate data sheet; this AD therefore does not include those 
airplanes in the applicability.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to address, among other things, fatigue cracking and 
damage in principal structural elements; such fatigue cracking and 
damage could result in reduced structural integrity of the airplane. 
See the MCAI for additional background information.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2020-0117 describes procedures for maintenance tasks and 
airworthiness limitations.
    This proposed AD would also require Chapter 5-40, Airworthiness 
Limitations, Revision 11, dated September 2018, of the Dassault Falcon 
900EX EASy, Falcon 900LX, and Falcon 900DX Maintenance Manual, which 
the Director of the Federal Register approved for incorporation by 
reference as of January 13, 2020 (84 FR 67171, December 9, 2019).
    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 
and service information referenced above. The FAA is proposing this AD 
because the FAA has 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 retain the requirements of AD 2019-23-03. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations, which are specified in EASA AD 
2020-0117 described previously, as incorporated by reference. Any 
differences with EASA AD 2020-0117 are identified as exceptions in the 
regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(m)(1) of this proposed 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 2020-0117 
will be incorporated by reference in the FAA final rule. This proposed 
AD would, therefore, require compliance with EASA AD 2020-0117 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 2020-0117 that is required 
for compliance with EASA AD 2020-0117 will be available on the internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2020-0677 after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness

[[Page 46562]]

limitations must be followed according to 14 CFR 91.403(c) and 
91.409(e).

Costs of Compliance

    The FAA estimates that this proposed AD affects 97 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2019-23-03 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
FAA recognizes that this number may vary from operator to operator. In 
the past, the FAA has estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), the FAA has determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, the FAA estimates the total cost per operator for the new 
proposed actions to be $7,650 (90 work-hours x $85 per work-hour).

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by

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.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2019-23-03, Amendment 39-19796 (84 FR 67171, December 9, 2019), and 
adding the following new AD:

Dassault Aviation: Docket No. FAA-2020-0677; Product Identifier 
2020-NM-099-AD.

(a) Comments Due Date

    The FAA must receive comments by September 17, 2020.

(b) Affected ADs

    (1) This AD replaces AD 2019-23-03, Amendment 39-19796 (84 FR 
67171, December 9, 2019) (``AD 2019-23-03'').
    (2) This AD affects AD 2010-26-05, Amendment 39-16544 (75 FR 
79952, December 21, 2010) (``AD 2010-26-05'').

(c) Applicability

    This AD applies to Dassault Aviation Model FALCON 900EX 
airplanes, serial number (S/N) 97 and S/Ns 120 and higher, 
certificated in any category, with an original airworthiness 
certificate or original export certificate of airworthiness issued 
on or before October 2, 2019.

(d) Subject

    Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks.

(e) Reason

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
issuing this AD to address, among other things, fatigue cracking and 
damage in principal structural elements; such fatigue cracking and 
damage could result in reduced structural integrity of the airplane.

(f) Compliance

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

(g) Retained Maintenance or Inspection Program Revision, With No 
Changes

    This paragraph restates the requirements of paragraph (i) of AD 
2019-23-03, with no changes. Within 90 days after January 13, 2020 
(the effective date of AD 2019-23-03), revise the existing 
maintenance or inspection program, as applicable, to incorporate the 
information specified in Chapter 5-40, Airworthiness Limitations, 
Revision 11, dated September 2018, of the Dassault Falcon 900EX 
EASy, Falcon 900LX, and Falcon 900DX Maintenance Manual. The initial 
compliance times for accomplishing the actions are at the times 
specified in Chapter 5-40, Airworthiness Limitations, Revision 11, 
dated September 2018, of the Dassault Falcon 900EX EASy, Falcon 
900LX, and Falcon 900DX Maintenance Manual, or 90 days after the 
effective date of this AD, whichever occurs later, except as 
provided by paragraphs (g)(1) through (4) of this AD. Accomplishing 
the maintenance or inspection program revision required by paragraph 
(i) of this AD terminates the requirements of this paragraph.
    (1) The term ``LDG'' in the ``First Inspection'' column of any 
table in the service information means total airplane landings.
    (2) The term ``FH'' in the ``First Inspection'' column of any 
table in the service information means total flight hours.
    (3) The term ``FC'' in the ``First Inspection'' column of any 
table in the service information means total flight cycles.
    (4) The term ``M'' in the ``First Inspection'' column of any 
table in the service information means months since the date of 
issuance of the original airworthiness certificate or the date of 
issuance of the original export certificate of airworthiness.

(h) Retained Restrictions on Alternative Actions and Intervals, With a 
New Exception

    This paragraph restates the requirements of paragraph (j) of AD 
2019-23-03, with a new exception. Except as required by paragraph 
(i) of this AD, after the existing maintenance or inspection program 
has been revised as required by paragraph (g) of this AD, no 
alternative actions (e.g., inspections) or intervals may be used 
unless the actions and intervals are approved as an AMOC in 
accordance with the procedures specified in paragraph (m)(1) of this 
AD.

(i) New Maintenance or Inspection Program Revision

    Except as specified in paragraph (j) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) AD 
2020-0117, dated May 20, 2020 (``EASA AD 2020-0117''). Accomplishing 
the maintenance or inspection program revision required by this 
paragraph terminates the requirements of paragraph (g) of this AD.

[[Page 46563]]

(j) Exceptions to EASA AD 2020-0117

    (1) The requirements specified in paragraphs (1) and (2) of EASA 
AD 2020-0117 do not apply to this AD.
    (2) Paragraph (3) of EASA AD 2020-0117 specifies revising ``the 
approved AMP'' within 12 months after its effective date, but this 
AD requires revising the existing maintenance or inspection program, 
as applicable, to incorporate the ``limitations, tasks and 
associated thresholds and intervals'' specified in paragraph (3) of 
EASA AD 2020-0117 within 90 days after the effective date of this 
AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2020-0117 is at the applicable ``associated 
thresholds'' specified in paragraph (3) of EASA AD 2020-0117, or 
within 90 days after the effective date of this AD, whichever occurs 
later.
    (4) The provisions specified in paragraphs (4) and (5) of EASA 
AD 2020-0117 do not apply to this AD.
    (5) The ``Remarks'' section of EASA AD 2020-0117 does not apply 
to this AD.

(k) New Provisions for Alternative Actions and Intervals

    After the maintenance or inspection program has been revised as 
required by paragraph (i) of this AD, no alternative actions (e.g., 
inspections) and intervals are allowed unless they are approved as 
specified in the provisions of the ``Ref. Publications'' section of 
EASA AD 2020-0117.

(l) Terminating Actions for Certain Actions in AD 2010-26-05

    Accomplishing the actions required by paragraph (g) or (i) of 
this AD terminates the requirements of paragraph (g)(1) of AD 2010-
26-05, for Dassault Aviation Model FALCON 900EX airplanes, 900EX 
airplanes, S/N 97 and S/Ns 120 and higher.

(m) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation Branch, FAA, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information
