Airworthiness Directives; Daher Aerospace Type Certificate Previously Held by SOCATA Airplanes Federal Aviation Administration FAA, DOT.
ACTION: Final rule.
AGENCY:

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.
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.
ADDRESSES: For service information identified in this final rule, contact Daher Aerospace Inc., Pompano Beach Airpark, 601 NE 10 Street, Pompano Beach, FL 33060; phone: 954 893

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 20180133, 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
061679 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 https
www.regulations.gov by searching for and locating Docket No. FAA2020
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
