All together, serving Civil Aviation

Aircraft used for general aviation generally have a lower complexity construction, but have a wide variety of construction variants.

Regulations (EU) 748/2012 and (EU) 1321/2014, which have been adapted for aircraft intended for use in this type of operation, shall apply to these aircraft in terms of airworthiness.

In accordance with Article 3 (2) of (EU) 1321/2014, Annex Vb (Part ML) applies to the following aircraft, other than complex motor-powered aircraft, which are not listed in an air operator's certificate (AOC):

a. airplane with a maximum take-off mass of up to 2730 kg;

b. helicopter with a maximum take-off mass of up to 1200 kg MTOM / max 4 passengers (including pilot);

c. ELA2 airplane [according to (EU) 1321/2014, Article 2, paragraph (ka)].


Article ML.A.201 states that:

The owner of an aircraft is responsible for maintaining the airworthiness of the aircraft and shall ensure that no flight is performed unless all of the following requirements are cumulatively met:

1. the aircraft is maintained in an airworthiness condition;

2. all operational and rescue components on board the aircraft are properly installed and operational or are clearly identified as unusable;

3. the certificate of airworthiness is valid;

4. the aircraft is maintained in accordance with the Aircraft Maintenance Program (AMP) under ML.A.302.


Airworthiness management information (EASA Part ML)

The owner can:

- contract an authorized Part CAMO / CAO / MG organization to carry out the continuing airworthiness management of the aircraft (Annex I of Part ML);

- take responsibility for the continuing airworthiness management of the aircraft.

The table in GM1 ML.A.201 summarizes the requirements for "light" aircraft.


Airworthiness certification information (EASA Part ML)

In accordance with (EU) 748/2012 an aircraft holding an EASA Type Certificate (TC)  and which may have been modified in accordance with an EASA Supplemental Type Certificate (STC) or in accordance with approved data shall qualify for an EASA Certificate of Airworthiness (EASA Form 25) without expiry date.

For an EASA Part ML aircraft, for which the requirements of Regulation (EU) 1321/2014, Annex Vb, Part ML apply (Part 'non-complex’ light aircraft) the Certificate of Airworthiness shall be valid together with an Airworthiness Review Certificate (EASA Form 15c) to be issued / renewed annually. The airworthiness review may be carried out by an authorized Part MG / CAMO / CAO organization, an authorized person or the RCAA (at the request of the owner).

The airworthiness requirements are defined in the procedure PIAC-AW-CNV.

For a better understanding, Annex 6 of the PIAC-AW-CNV briefly describes the airworthiness review process depending on the type of aircraft operation.

The forms applicable to the application for airworthiness certification can be downloaded by accessing the page: (point 2).


Maintenance program information (EASA PArt ML - Annex Vb ML.A.302 (c) and AMC MLA.302)

For aircraft to which the Part-ML Annex applies, the maintenance program shall not be approved by the RCAA. The owner or the contracted organization "CAMO / CAO / MG" will establish the development of the program and its evaluation.

It can be approved by the "CAMO / CAO / MG" organization contracted or assumed by the pilot-owner, by a declaration signed by him by which he assumes responsibility for its content, periodic evaluation and amendment whenever necessary, including deviations from the non-binding recommendations of the aircraft manufacturer (the declared program must be reviewed at least annually by the airworthiness assessor).

EASA has published “model” versions for the maintenance program in accordance with ML.A.302 in AMC2 ML.A.302.

By exception, if the requirements of ML.A.302 (e) are complied with, a maintenance program is not required (all continuing airworthiness instructions (ICA) issued by the type-certificate holder shall be met without deviations, all recommendations shall be considered without deviations and there shall be no additional maintenance work as a result of equipment installations/repairs performed). The statement must take into account the requirements of ML.A.302 (f).

Throughout this page, references to ML.A. ..., AMC ML.A. ... and GM ML.A. ... shall be understood as references to various articles of Regulation (EU) 1321/2014, Annex Vb (Part ML) and to acceptable means of compliance (AMC) and guidance materials (GM) published by EASA.

The consolidated version of this regulation, which also includes AMC and GM, can be viewed on the EASA Easy Access Rules page.
