SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain serial-numbered
Daher Aerospace (type certificate previously held by SOCATA) Model TBM
700 airplanes. The NPRM published in the Federal Register on September
14, 2021 (86 FR 51033). The NPRM was prompted by MCAI originated by the
European Union Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union. EASA issued 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.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
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 reviewed the relevant
data and determined that air safety requires adopting this AD as
proposed. Accordingly, the FAA is issuing this AD to address the unsafe
condition on these products. This AD is adopted as proposed in the
NPRM.
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.
Costs of Compliance
The FAA estimates that this AD affects 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 required by this AD. The average labor rate is $85 per
work-hour.
Based on these figures, the FAA estimates the inspection cost of
this 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 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
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 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.

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:
2021-24-13 Daher Aerospace (Type Certificate Previously Held by
SOCATA): Amendment 39-21834; Docket No. FAA-2021-0778; Project
Identifier 2019-CE-062-AD.
[[Page 69581]]
(a) Effective Date
This airworthiness directive (AD) is effective January 12, 2022.
(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) 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-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, 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,
