AD 2020-15-05 Airworthiness Directives; Austro Engine GmbH Engines
Makes named: austro. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to Austro Engine GmbH model E4 engines with serial numbers that have a “-B” or “-C” configuration and to model E4P engines, all serial numbers.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
(1) Within 30 days after the effective date of this AD, under the Emergency Procedures chapter, amend the applicable airplane flight manual (AFM) by adding the information in Figure 1 to paragraph (g)(1) of this AD to limit the use of a windmilling restart to only an emergency procedure. ER27JY20.001 (2) For affected Austro Engine GmbH model E4 engines installed on Diamond Aircraft Industries (DAI) model Diamond Aircraft (DA) 42 NG and DA 42 M-NG airplanes, and for Austro Engine GmbH model E4P engines installed on DAI model DA 62 airplanes, using DA AFM Temporary Revision (TR) TR-MÄM-42-973, and DA AFM TR TR-MÄM-62-240, both dated August 12, 2016, to update the applicable AFM is an acceptable method to comply with paragraph (g)(1) of this AD. (h) Credit for Previous Actions You may take credit for actions required by paragraph (g) of this AD if you amended the applicable AFM for the airplane with the affected engine installed before the effective date of this AD in accordance with AD 2018-18-02.
Unsafe condition
This AD was prompted by reports of considerable wear of the timing chain on the affected engines. The FAA is issuing this AD to prevent failure of the engine timing chain. The unsafe condition, if not addressed, could result in failure of the engine timing chain, loss of engine thrust control, and reduced control of the airplane.
Affected ADs
This AD replaces AD 2018-18-02, Amendment 39-19381 (83 FR 53802, October 25, 2018).
