COMMISSION IMPLEMENTING REGULATION (EU) 2025/111
of 23 January 2025
amending Regulation (EU) No 1321/2014 as regards continuing airworthiness for electric- and
hybrid-propulsion aircraft and other non-conventional aircraft
(Text with EEA relevance)
THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Regulation (EU) 2018/1139 of the European Parliament and of the Council of 4 July 2018on common
rules in the field of civil aviation and establishing a European Union Aviation Safety Agency, and amending Regulations
(EC) No 2111/2005, (EC) No 1008/2008, (EU) No 996/2010, (EU) No 376/2014 and Directives 2014/30/EU
and 2014/53/EU of the European Parliament and of the Council, and repealing Regulations (EC) No 552/2004 and (EC)
No 216/2008 of the European Parliament and of the Council and Council Regulation (EEC) No 3922/91(1), and in
particular Article 17(1), point (b) and points (d) to (f), thereof,
Whereas:
(1) Commission Regulation (EU) No 1321/2014(2) lays down the requirements for the continuing airworthiness of
aircraft, including the qualifications and licences of the personnel responsible for the release to service of products
after maintenance.
(2) Regulation (EU) No 1321/2014 explicitly specifies the aircraft categories to which the requirements apply, namely
aeroplane, helicopter or rotorcraft, sailplane, balloon and airship. There exist certain non-conventional aircraft,
primarily emerging from recent industrial developments, referred to as new air mobility aircraft, which do not fit
within any of the aforementioned aircraft categories. This creates legal uncertainty regarding the applicability of
specific aspects of the current regulatory framework to these aircraft. In addition, existing alleviations covered by
Regulation (EU) No 1321/2014 applicable to aircraft of comparable safety risk should also be extended to non-
conventional aircraft by analogy.
(3) Similarly, there are regulatory gaps stemming from the fact that Regulation (EU) No 1321/2014 is sometimes
prescriptive on the aircraft power plant, only considering piston and turbine engines as power plants for aeroplanes
and helicopters. This is not in line with new industrial developments that consider other power plants, such as
electrical engines or hybrid ones. It is also necessary to to cater for a smooth transition for the new rules so that
they do not impede the introduction of small electrical aeroplanes, in particular in respect of their aircraft
maintenance license.
(4) In order to address those regulatory gaps, requirements should apply to any current or future aircraft developments
and their power plants.
(5) By considering all tilt-rotors as complex motor-powered aircraft, Regulation (EU) No 1321/2014 was not
commensurate for the simplest ones as stringent requirements applicable to any complex motor-powered aircraft
was also applicable to the simplest tilt-rotors, for which less stringent requirements should apply by comparison
with simple aircraft of other categories, namely aeroplanes and helicopters. Therefore the definition of complex
motor-powered aircraft should therefore be amended
(6) Regulation (EU) No 1321/2014 should therefore be amended accordingly.

products, parts and appliances, and on the approval of organisations and personnel involved in these tasks (OJ L 362, 17.12.2014,

of gas airships, where it shall be directly approved by the competent authority.
The on-the-job training on an aircraft referred to in point (b) of point 66.A.3 may only be considered for the purpose of endorsement of the licence as the first aircraft type
rating within a given (sub)category, as described in the previous paragraph, when so established in the aircraft operational suitability data.
Otherwise, an aircraft referred to in point (b) of point 66.A.3 may be endorsed as a first aircraft type rating within a given (sub)category after satisfactory completion of the
corresponding on-the-job training, but in such case, additional on-the-job training will be required for the endorsement on the licence within that (sub)category of the first
aircraft type rating belonging to the categories referred in point (a) of point 66.A.3.β;

under the condition that the aircraft type rating is not the first aircraft endorsed for that (sub)category.
Such training shall be carried out at a level and duration that meet the same objectives as those of points 5 (a), (b) and (c) of Appendix III, and shall cover relevant
maintenance data at the required knowledge level and scope for the AML (sub)category.

Annex Vd (Part-CAO) to Regulation (EU) No 1321/2014 is amended as follows:
(1) point CAO.A.020(a) is amended as follows:
(a) points (1), (2) and (3) are replaced by the following:
β(1) For aeroplanes of more than 2 730 kg maximum take-off mass (MTOM) and for helicopters of more than
1 200 kg MTOM or certified for more than four occupants and for other aircraft which are not ELA2, the
scope of work shall indicate the particular aircraft types. Changes to this scope of work shall be approved by
the competent authority in accordance with point (a) of point CAO.A.105 and point (a) of point CAO.B.065.
(2) For engines other than piston or electric, the scope of work shall indicate the engine manufacturer or group or
series or type or the maintenance task(s). Changes to this scope of work shall be approved by the competent
authority in accordance with point (a) of point CAO.A.105 and point (a) of point CAO.B.065.
(3) A CAO which employs only one person for both planning and carrying out of all maintenance tasks cannot
hold privileges for the maintenance of:
(a) aeroplanes, helicopters and other aircraft which are not ELA2, if their power plant is other than electric
or piston engine(s) (in the case of aircraft-rated organisations);
(b) helicopters equipped with more than one piston engine (in the case of aircraft-rated organisations);
(c) complete engines other than piston engines with output power below 450 HP or electric engines (in the
case of engine-rated organisations).β;
(b) in point (4), points (xxi) and (xxii) are replaced by the following:
β(xxi) C21: water ballast;
(xxii) C22: propulsion augmentation;β;

(2) in point CAO.A.105, point (a) is replaced by the following:
β(a) In order to enable the competent authority to determine continued compliance with this Annex, the CAO shall
notify the competent authority of any proposal to carry out any of the following changes, before such changes
take place:
(1) changes affecting the information contained in the approval certificate laid down in Appendix I and the terms
of approval of this Annex;
(2) changes of the persons referred to in points CAO.A.035(a) and (b);
(3) changes in the aircraft types covered by the scope of work referred to in point (a)(1) of point CAO.A.020 in
the case of aeroplanes of more than 2 730 kg maximum take-off mass (MTOM), helicopters of more than
1 200kg MTOM or certified for more than four occupants and for any other aircraft which is not an ELA2;
(4) changes in the scope of work referred to in point (a)(2) of CAO.A.020 in the case of engines other than piston
or electric;
(5) changes in the control procedure set out in point (b) of this point.β;
(3) Appendix I is amended as follows:
(a) point (c) is replaced by the following:
β(c) An engine rating (turbine, piston, electric or other) means that the CAO may carry out maintenance on the
uninstalled engine and engine components, in accordance with engine maintenance data or, if agreed by the
competent authority, in accordance with component maintenance data, only whilst such components are
fitted to the engine. Nevertheless, such engine-rated CAO may temporarily remove a component for

additional maintenance not eligible for the requirements of point (c). An engine-rated CAO may also carry
out maintenance on an installed engine during base and line maintenance subject to a control procedure in
the CAE to be approved by the competent authority.β;
(b) the identification of the form βEASA Form 3-CAO, Issue 1β is replaced by βEASA Form 3-CAO, Issue 2β;
