Can an airworthiness review recommendation be issued for an aircraft under Part ML?

No, the standard does not provide for the possibility of issuing airworthiness review recommendations for aircraft under Part ML. 

In the case of importing an aircraft from a third country or from a regulatory system where Regulation (EU) 2018/1139 does not apply: 

• In the case of a new aircraft, the issuance of the ARC by the competent authority of the Member State of registry shall be requested. 
• In the case of a used aircraft, it shall be the CA(M)O, the maintenance organisation or the personnel conducting the airworthiness review, as provided in ML.A.901(b), which shall issue the ARC and submit a copy to the competent authority of the Member State of registry.  

The ARC shall not be valid until the Certificate of Airworthiness is also issued by the competent authority of the Member State of registration.
