Daher Aerospace (Type Certificate Previously Held by SOCATA) Airplanes
This AD applies to Daher Aerospace (type certificate previously held by SOCATA) Model TBM 700 airplanes, all serial numbers, certificated in any category, with an oil cooler air induction duct part number (P/N) T700A7920040001, T700H792000900000, T700H792001900000, T700H792001900200, T700H792001900400, or T700H792001900600 installed.
Note 1 to paragraph (c) of this AD: The applicable oil cooler air induction duct P/Ns may be installed in accordance with modification 70-0435-79; Daher Aerospace Service Bulletin SB 70-231, Revision 1, dated July 2018; or Daher Aerospace Service Bulletin SB 70-219, Revision 2, dated July 18, 2018.
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.
(1) Within 3 months after the effective date of this AD, remove 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 T700H792001900600 on any airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
