Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Daher Aerospace (type certificate previously held by SOCATA) (Daher) Model TBM 700 airplanes. This AD results from 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 unsafe condition that is the subject of the MCAI is ice accumulation on the oil cooler air inlet duct fin. This AD requires modifying the oil cooler air induction duct. The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Daher Aerospace (type certificate previously held by SOCATA)

continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The unsafe condition that is the
subject of the MCAI is ice accumulation on the oil cooler air inlet
duct fin. This AD requires modifying the oil cooler air induction duct.
The FAA is issuing this AD to address the unsafe condition on these
products.
DATES: This AD is effective January 24, 2022.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 24,
2022.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to Daher Model TBM 700
airplanes with certain oil cooler air induction ducts installed. The
NPRM published in the Federal Register on August 18, 2021 (86 FR
46160). The NPRM was based on MCAI from the European Aviation Safety
Agency (EASA), which is the Technical Agent for the Member States of
the European Union. EASA issued AD 2018-0133, dated June 22, 2018, and
corrected June 25, 2018 (referred to after this as ``the MCAI''), to
address the unsafe condition on certain Daher Model TBM 700 airplanes.
The MCAI states:
During flight testing in icing conditions, oil temperature
increase was observed. Subsequent investigation determined that the
loss of efficiency of the oil cooler system was due to ice
accumulation on the engine air induction duct fins.
This condition, if not corrected, could lead to uncommanded
engine in-flight shut-down and reduced control of the aeroplane.
To address this potential unsafe condition, DAHER AEROSPACE
developed MOD 70-0616-79 for aeroplanes in production, removing the
4 upper fins of the oil cooler air induction duct to avoid ice
accumulation, available for in-service aeroplanes through the SB
[Daher Aerospace Service Bulletin 70-254, dated April 18, 2018].
For the reasons described above, this [EASA] AD requires
modification of the oil cooler air induction duct.
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-2020-
1069.
Although the unsafe condition statement in the MCAI identifies the
cause as ice accumulation on the engine air induction fin, the FAA has
determined that this does not accurately identify the affected air
path. The affected area is the oil cooler air inlet duct fin.
In the NPRM, the FAA proposed to require modifying the oil cooler
air
[[Page 71824]]
induction duct. The FAA is issuing this AD to prevent ice from
accumulating on the oil cooler air induction duct fins, which could
lead to an increase in oil temperature, uncommanded engine inflight
shutdown, and reduced airplane control.
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
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 70-254, dated
April 2018. The service information specifies procedures for removing
the four upper fins of the oil cooler air induction duct and for re-
identifying the oil cooler air induction duct with a new part number.
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.
Other Related Service Information
The FAA also reviewed Daher Aerospace Service Bulletin SB 70-231,
Revision 1, dated July 2018; and Daher Aerospace Service Bulletin SB
70-219, Revision 2, dated July 2018. The service information identifies
the kit number and installation procedures for replacing the oil cooler
air induction duct.
Costs of Compliance
The FAA estimates that this AD will affect up to 807 airplanes of
U.S. registry. The FAA also estimates that it would take about 3 work-
hours per airplane to comply with the requirements of this AD. The
average labor rate is $85 per work-hour. Required parts will cost about
$50 per airplane.
Based on these figures, the FAA estimates the total cost of this AD
on U.S. operators to be $246,135 or $305 per airplane.
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.

2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2021-25-10 Daher Aerospace (Type Certificate Previously Held by
SOCATA): Amendment 39-21854; Docket No. FAA-2020-1069; Project

country to identify and correct an unsafe condition on an aviation
product. The unsafe condition that is the subject of the MCAI is ice
accumulation on the oil cooler air inlet duct fin. The FAA is
issuing this AD to prevent ice from accumulating on the oil cooler
air induction duct fins, which could lead to an increase in oil

the four upper fins of the oil cooler air induction duct and re-
identify the oil cooler air induction duct in accordance with the
Description of Accomplishment Instructions in Daher Aerospace
Service Bulletin SB 70-254, dated April 2018.
(2) As of the effective date of this AD, do not install an oil
cooler air induction duct P/N T700A7920040001, T700H792000900000,
T700H792001900000, T700H792001900200, T700H792001900400, or
