PROPOSED AD DASSAULT AVIATION: Docket No. FAA-2019-0604; Product Identifier 2019-NM-072-AD.
(a) COMMENTS DUE DATE

    The FAA must receive comments by September 27, 2019.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This  AD  applies  to  all  Dassault Aviation Model MYSTERE FALCON 50,
    MYSTERE FALCON 900, and FALCON 900EX airplanes;  and Model FALCON 2000
    and FALCON 2000EX airplanes; certificated in any category.

(d) SUBJECT

    Air Transport Association (ATA) of America Code 26, Fire protection.

(e) REASON

    This  AD  was  prompted  by a  report  that  the  Dassault maintenance
    planning document (MPD) of  the related Dassault aircraft  maintenance
    manual (AMM) mentions that the "combined service/storage life" of  the
    fire extinguisher percussion cartridges is 12 years, whereas it should
    be 10 years, and could have a  safety impact in case of fire. The  FAA
    is  issuing  this AD  to  address the  total  life limit  of  the fire
    extinguisher  percussion  cartridges, which  if  not corrected,  could
    prevent extinguishing  a fire  and possibly  result in  damage to  the
    airplane and injury to occupants.

(f) COMPLIANCE

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

(g) DEFINITIONS

    For the purpose  of this AD,  the definitions specified  in paragraphs
    (g)(1), (g)(2), (g)(3), and (g)(4) apply to this AD.

(1) An  affected  part  is a fire extinguisher percussion cartridge having
    part number (P/N) 862700-00 or P/N 862710-00.

(2) Total life is time since the manufacturing date,  which  includes both
    the time installed on an airplane and time in storage.

(3) A serviceable part is an affected part  that has not exceeded 10 years
    of total life, or a fire extinguisher percussion cartridge that is not
    an affected part.

(4) Group 1 airplanes are  those  that  have  an  affected part installed.
    Group 2 airplanes  are  those  that  do not have  an affected part in-
    stalled.

(h) TOTAL LIFE LIMIT IMPLEMENTATION

    For Group 1  airplanes, except as  specified in paragraph  (j) of this
    AD: Before a fire  extinguisher percussion cartridge exceeds  10 years
    of  total  life,  remove  the affected  part  and  replace  it with  a
    serviceable  part  in  accordance  with  the  procedures  specified in
    paragraph (l)(2) of this AD.

(i) GUIDANCE FOR REPLACEMENT REQUIRED BY PARAGRAPH (H) OF THIS AD

    Guidance for the replacement specified in paragraph (h) of this AD can
    be found in the applicable Dassault AMM task as specified  in figure 1
    to paragraph (i) of this AD.

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 adopt a new airworthiness directive (AD)
for all Dassault Aviation Model MYSTERE FALCON 50, MYSTERE FALCON 900,
and FALCON 900EX airplanes; and Model FALCON 2000 and FALCON 2000EX
airplanes. This proposed AD was prompted by a report that the Dassault
maintenance planning document (MPD) of the related Dassault aircraft
maintenance manual (AMM) states that the "combined service/storage
life" of the fire extinguisher percussion cartridges is longer than it
should be, and could have a safety impact in case of fire. This
proposed AD would require replacing the fire extinguisher percussion
cartridges with serviceable parts. 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 27,
2019.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA AD
2019-0084, dated April 17, 2019 (referred to after this as the
Mandatory Continuing Airworthiness Information, or "the MCAI"), to
correct an unsafe condition for all Dassault Aviation Model MYSTERE
FALCON 50, MYSTERE FALCON 900, and FALCON 900EX airplanes; and Model
FALCON 2000 and FALCON 2000EX airplanes. The MCAI states:

It was identified that the Dassault Maintenance Planning
Document (MPD) of the related Dassault Aircraft Maintenance Manual
(AMM) for affected aeroplanes mentions that "combined service/
storage life" of the affected parts is 12 years, whereas it should
be 10 years. The related technical investigation confirmed that this
could have a safety impact in case of fire. It is expected that
Dassault will update the MPD with the correct value.

This condition, if not corrected, could prevent extinguishing a
fire, possibly resulting in damage to the aeroplane and injury to
the occupants.

For the reasons described above, this [EASA] AD requires
replacement of affected parts with serviceable parts.

You may examine the MCAI in the AD docket on the internet at http://www.
regulations.gov by searching for and locating Docket No. FAA-2019-0604.

FAA's Determination

This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to a 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 agency evaluated all the relevant information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design.

Proposed Requirements of This NPRM

This proposed AD would require replacing the fire extinguisher
percussion cartridges with serviceable parts.

Costs of Compliance

The FAA estimates that this proposed AD affects 1,013 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
6 work-hours x $85 per hour = $510
$1,145
$1,655
$1,676,515

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.

This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes and associated appliances to the
Director of the System Oversight Division.

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
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

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]

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
