2022-12-10 DASSAULT AVIATION: Amendment 39-22082; Docket No FAA-2022-0390; Project Identifier MCAI-2021-00968-T.
(a) EFFECTIVE DATE

    This airworthiness directive (AD) is effective September 1, 2022.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies  to all  Dassault Aviation  Model FALCON 7X airplanes,
    certificated  in  any  category,  except  airplanes  having   Dassault
    modification M2091 embodied in production.

Note 1 to paragraph (c): Model FALCON 7X airplanes with Dassault modifica-
tion M1000 incorporated are commonly referred to as "Model FALCON 8X" as a
marketing designation.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 34, Navigation.

(e) UNSAFE CONDITION

    This AD was prompted  by  a  report  of a weak point identified in the
    Falcon 7X 'EASy' avionics architecture, which coupled with theoretical
    generic input/output (I/O) card failure, could lead to misleading data
    on  display  units.  The  FAA  is  issuing  this  AD  to  address this
    condition, which  could reduce  safety margins  and lead  to increased
    pilot  workload,  and   consequent  reduced  controllability   of  the
    airplane.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) REQUIREMENTS

    Except as specified in paragraphs (h) and (i) of this AD:  Comply with
    all required actions and compliance times specified in, and in accord-
    ance with,  European Union Aviation Safety Agency (EASA) AD 2021-0197,
    dated August 23, 2021 (EASA AD 2021-0197).

(h) EXCEPTIONS TO EASA AD 2021-0197

(1) Where EASA AD 2021-0197 refers to its effective date, this AD requires
    using the effective date of this AD.

(2) Whereas EASA AD 2021-0197  requires  operators  to  "inform all flight
    crews and, thereafter, ensure that each pilot has performed the train-
    ing and operate the aeroplane accordingly,"  this AD  does not require
    those actions.

(3) Where paragraph (3) of EASA AD 2021-0197  specifies to  "implement the
    instructions of the MMEL-CP," this AD requires revising the operator's
    existing FAA-approved minimum equipment list (MEL) to incorporate that
    information ("the MMEL-CP" as specified in EASA AD 2021-0197).

(4) Paragraph (4) of EASA AD 2021-0197 does not apply to this AD.

(5) The "Remarks" section of EASA AD 2021-0197 does not apply to this AD.

(i) AIRPLANE FLIGHT MANUAL (AFM) REVISION

    Within  2 months  after  the  effective date  of this  AD, revise  the
    applicable existing  AFM to  incorporate the  information specified in
    figure 1 to paragraph (i)  of this AD after sub-sub-section  2-200-70,
    Emergency Procedures,  ADS with IRS miscompare,  of sub-section 2-200,
    Emergency Procedures, of Section 2-Emergency Procedures.

    FIGURE 1 TO PARAGRAPH (I)–TRAINING AREAS OF SPECIAL EMPHASIS FOR PILOT

                      (TASEp) Tp-118-EZII Info for AFM
    ______________________________________________________________________
                        TASEp Tp-118-EZII Information

    1) Potentially unreliable information exists on the iPFD and/or HUD
    2) Aircraft must be flown by reference to SFD
    3) Aircraft trajectory must be monitored on the iNAV
    4) The iNAV may have misleading/confusing representations
    5) Before using iNAV for aircraft trajectory monitoring, LH pilot side
       is to be selected
    6) Pilot side selection has impacts on task sharing between Pilot Fly-
       ing and Pilot Monitoring
    7) Presence of both ADS and IRS CAS messages requires that newly devel
        -oped single emergency procedure must be performed instead of per-
        forming separate ADS and IRS emergency procedures
    8) There may be a time delay of up to 10 secs between the ADS and IRS
       MISCOMPARE messages during critical phases of flight
    9) The special single emergency procedure is not available on ECL (pa-
       per checklist from AFM or CODDE2 is required)
    10) Crew workload in this failure situation will be high
    ______________________________________________________________________

Airworthiness Directives; Dassault Aviation Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a
report of a weak point identified in the Falcon 7X `EASy' avionics
architecture, which, coupled with theoretical generic input/output (I/
O) card failure, could lead to misleading data on display units. This
AD requires revising the existing airplane flight manual (AFM) to
provide emergency procedures for inconsistent or unreliable flight data
and emergency and abnormal operations procedures for the GEN I/O
internal module failure, and revising the operator's existing FAA-
approved minimum equipment list (MEL) items for the multi-function
probe heating, air data, and inertial reference systems, as specified
in a European Union Aviation Safety Agency (EASA) AD, which is
incorporated by reference. This AD also requires revising the existing
AFM to incorporate additional information in the emergency procedures.
The FAA is issuing this AD to address the unsafe condition on these
products.

DATES: This AD is effective September 1, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of September 1,
2022.

SUPPLEMENTARY INFORMATION:

Background

EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0197, dated August 23, 2021
(EASA AD 2021-0197) (also referred to as the MCAI), to correct an
unsafe condition for all Dassault Aviation Model FALCON 7X airplanes.
The FAA notes that Model FALCON 7X airplanes with Dassault modification
M1000 incorporated are commonly referred to as ``Model FALCON 8X'' as a
marketing designation.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Dassault Aviation
Model FALCON 7X airplanes. The NPRM published in the Federal Register
on April 5, 2022 (87 FR 19653). The NPRM was prompted by a report of a
weak point identified in the Falcon 7X `EASy' avionics architecture,
which, coupled with theoretical generic I/O card failure, could lead to
misleading data on display units. The NPRM proposed to require revising
the existing AFM to provide emergency procedures for inconsistent or
unreliable flight data and emergency and abnormal operations procedures
for the GEN I/O internal module failure, and revising the operator's
existing FAA-approved MEL items for the multi-function probe heating,
air data, and inertial reference systems, as specified in EASA AD 2021-
0197. The NPRM also proposed to require revising the existing AFM to
incorporate additional information in the emergency procedures.
The FAA is issuing this AD to address misleading data on display
units, which could reduce safety margins and lead to increased pilot
workload, and consequent reduced controllability of the airplane. See
the MCAI for additional background information.

Discussion of Final Airworthiness Directive

Comments

The FAA received no comments on the NPRM or on the determination of
the cost to the public.

Change to the Applicability

The FAA has revised paragraph (c) of this AD to exclude airplanes
having Dassault modification M2091 embodied in production from the
applicability because those airplanes are not affected by the
identified unsafe condition. Modification M2091 upgrades the airplane
avionics to the ``EASY III--4th CERT'' standard that improves the
Falcon 7X EASy avionics architecture. This change to the applicability
corresponds to EASA AD 2022-0145, dated July 12, 2022 (EASA AD 2022-
0145), which supersedes EASA AD 2021-0197. EASA AD 2022-0145 also
requires an additional modification for certain airplanes. The FAA is
considering further rulemaking to mandate the new modification
specified in EASA AD 2022-0145.
The FAA has also added Note 1 to paragraph (c) of this AD to
explain that Model FALCON 7X airplanes with
Dassault modification M1000 incorporated are commonly referred to as
``Model FALCON 8X'' as a marketing designation.

Conclusion

The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed with the changes described
previously. Except for minor editorial changes, this AD is adopted as
proposed in the NPRM. None of the changes will increase the economic
burden on any operator. Accordingly, the FAA is issuing this AD to
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

EASA AD 2021-0197 specifies procedures for revising the existing
AFM to provide emergency procedures for inconsistent or unreliable
flight data and emergency and abnormal operations procedures for the
GEN I/O internal module failure, revising the operator's existing MEL
for the air data and inertial reference systems, and revising the
operating suitability manual. 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.

Interim Action

The FAA considers this AD interim action. If final action is later
identified, the FAA might consider further rulemaking then.

Costs of Compliance

The FAA estimates that this AD affects 121 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions

Labor cost
Parts cost
Cost per product
Cost on U.S. operators
2 work-hours x $85 per hour = $170
$0
$170
$20,570

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.
