Under the provisions of The Aviation Safety (Amendment)(No.2) Regulations 2025, the following comes into effect today, 1st October 2025:
Hours flown on aeroplanes specified in paragraph (1)(e) of Annex 1 to Regulation (EU) 2018/1139 or aircraft the subject of a decision of the CAA in accordance with Article 2(8) of that Regulation may be credited when conducted on aeroplanes equipped with a three-axis control system towards meeting:
(i) the fight time and other requirements of FCL.140.A(a) or FCL.740.A; or
(ii)the flight time requirements of FCL.210.A(a).”.
Annex 1(e) aeroplanes are microlights; if equipped with three-axis control systems, they meet the 'flight time and other requirements of FCL.740.A', which includes 'refresher training of at least 1 hour of total flight time with a flight instructor (FI) or class rating instructor'.
So in my opinion, the answer to your question is 'yes'. Provided of course, that the refresher training is conducted in accordance with 'AMC1 FCL.740.A(b)(1)(ii) Revalidation of class and type ratings' and 'GM1 FCL.740.A Revalidation of class and type ratings – aeroplanes [new]', both of which are included in ORS9 Decision No. 0053, which may be viewed at:
