Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Daher Aerospace (type certificate previously held by SOCATA) Model TBM 700 airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a non-conforming dump switch ejecting from its slot. This proposed AD would require modifying certain dump switches. The FAA is proposing this AD to address the unsafe condition on these products.

Background
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union, has issued
EASA AD 2019-0306, dated December 18, 2019 (referred to after this as
``the MCAI''), to address the unsafe condition on certain serial-
numbered Daher Aerospace (formerly SOCATA) Model TBM 700 airplanes. The
MCAI states:
It has been determined that, in certain conditions, an affected
switch [dump switch part number 7388475012 without a seal] may eject
from its slot. Investigations identified the root cause in a non-
conformity of the affected switch.
This condition, if not corrected, could, in case of smoke/fumes
in the cabin, prevent evacuation of the smoke/fumes, possibly
resulting in excessive flight crew workload and/or injury to
aeroplane occupants.
To address this potential unsafe condition, DAHER AEROSPACE
issued the [service bulletin] SB to provide modification
instructions.
For the reasons described above, this [EASA] AD requires
modification of the affected parts by installation of a seal, and
introduces requirements for installation of a dump switch.
You may examine the MCAI in the AD docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0778.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Daher Aerospace Service Bulletin SB 70-271-21,
Revision 1, dated November 2019. The service information contains
procedures for modifying each dump switch part number 7388475012 by
removing the two indicator light units, installing a seal, installing a
thin layer of grease, and installing the two indicator lights. This
service information 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
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 this State of Design Authority,
it has notified the FAA of the unsafe condition described in the MCAI
and service information referenced above. The FAA is issuing this NPRM
after determining the unsafe condition described previously 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 the service information already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 150 airplanes of U.S. registry. The FAA also estimates that it
would take about 1 work-hour per airplane and require parts costing
$800 to comply with the modification that would be required by this
proposed AD. The average labor rate is $85 per work-hour.
Based on these figures, the FAA estimates the inspection cost of
this proposed AD on U.S. operators to be $132,750, or $885 per
airplane.
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators.
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.

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 adding the following new airworthiness
directive:
Daher Aerospace (Type Certificate Previously Held by SOCATA): Docket
No. FAA-2021-0778; Project Identifier 2019-CE-062-AD.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by October 29, 2021.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Daher Aerospace (type certificate previously
held by SOCATA) Model TBM 700 airplanes, serial numbers 1106 and
larger, certificated in any category.
(d) Subject
Joint Aircraft System Component (JASC) Code 2130, Cabin Pressure
Control System.
(e) Unsafe Condition
This AD was prompted by mandatory continuing airworthiness
information (MCAI)
[[Page 51035]]
originated by an aviation authority of another country to identify
and address an unsafe condition on an aviation product. The MCAI
describes the unsafe condition as a non-confirming dump switch
ejecting from its slot. The FAA is issuing this AD to prevent dump
switches ejecting from their slots, which, in case of smoke/fumes in
the cabin, could prevent evacuation of the smoke/fumes. The unsafe
condition, if not addressed, could result in excessive flight crew
workload and injury to airplane occupants.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
Within 12 months after the effective date of this AD, inspect
each dump switch part number (P/N) 7388475012 to determine if a seal
is installed, as depicted in Figure 3 of Daher Aerospace Service
Bulletin SB 70-271-21, Revision 1, dated November 2019.
(1) If a seal is installed, no further action is required by
this paragraph.
(2) If a seal is not installed, within 12 months after the
effective date of this AD, modify the dump switch in accordance with
steps 2) through 5) of the Description of Accomplishment
Instructions in Daher Aerospace Service Bulletin SB 70-271-21,
Revision 1, dated November 2019.
(h) Parts Installation Provision
As of the effective date of this AD, do not install a dump
switch P/N 7388475012 on any airplane unless the switch has been
modified as described in Daher Aerospace Service Bulletin SB 70-271-
21, Revision 1, dated November 2019. Removal of a dump switch from
an airplane and re-installation of that dump switch on the same
airplane within the same maintenance visit is not an installation
for purposes of this paragraph.
(i) Alternative Methods of Compliance (AMOCs)
(1) The Manager, General Aviation & Rotorcraft 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 directly to the manager of the
International Validation Branch, send it to the attention of the
