(d) Subject Joint Aircraft System Component (JASC) Code 2460, DC Power/Distribution 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 states that failure to revise the airworthiness limitations section (ALS) of the existing aircraft maintenance manual (AMM) by introducing new or more restrictive tasks and limitations, which introduces a new certification maintenance requirement (CMR) task to test emergency power contactor 2, could result in an unsafe condition. The FAA is issuing this AD to address failure of certain parts, which could result in loss of control of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) Before further flight after the effective date of this AD, revise the ALS of the existing AMM or Instructions for Continued Airworthiness for your airplane by incorporating the requirements specified in paragraph (1) of European Union Aviation Safety Agency AD 2022-0207, dated October 10, 2022 (EASA AD 2022-0207). (2) The actions required by paragraph (g)(1) of this AD may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with §§ 43.9(a) and 91.417(a)(2)(v). The record must be maintained as required by § 91.417, 121.380, or 135.439. (h) Provisions for Alternative Requirements (Airworthiness Limitations) After the actions required by paragraph (g) of this AD have been done, no alternative requirements (airworthiness limitations) are allowed unless they are approved as specified in the provisions of the "Ref.
