MANDATORY MODIFICATIONS AND INSPECTIONS
(AIRWORTHINESS DIRECTIVES)
1. Introduction
1.1 The Director General of Department of Civil Aviation, Myanmar (DCA) is
empowered under the Myanmar Aircraft Act to prescribe requirements concerning
the inspection or modification of aircraft registered in Myanmar in respect of which
Certificates of Airworthiness are or have been in force. Such requirements are
classified as mandatory modifications and inspections.
1.2 When an aircraft is affected by a mandatory inspection or modification issued in
accordance with paragraph 1.1, it is illegal for the aircraft to be flown (unless
permission has been granted by the DCA either generally or in relation to a specific
case) until the prescribed requirement has been complied with.
1.3 Operators of aeroplanes over 5700 kg or helicopters over 3175 kg maximum
certificated take-off mass are required to obtain and assess continuing airworthiness
information and recommendations relating to the relevant types of aircraft, engines
and equipment from the organization responsible for the type design.
2. Compliance
2.1 The prescribed requirements for mandatory modifications and inspections issued by
DCA are those which arise from the following sources: -
(a) Airworthiness Directives (ADs) issued by the State of Design of a particular
aircraft, its engines, propellers or installed equipment.
(b) Special Airworthiness Directives issued by the DCA.
2.2 The Myanmar fleet of civil registered aircraft is comparatively small in size but the
DCA cannot, on economic grounds, justify the preparation, issue and revision
service of a summary of Myanmar mandatory modifications and inspections which
would include in the sources stated in paragraph 2.1 above.
2.3 Unless otherwise directed by DCA, owners or operators of aircraft registered in the
Union of Myanmar must comply with all ADs or similar mandatory instructions
issued by the Airworthiness Authority of the State of Design.
2.4 Operations and Maintenance Organizations are reminded that they are, therefore,
required to obtain all mandatory continuing airworthiness information including
ADs issued by the State of Design concerning the types of aircraft, engines and
equipment with which they are involved.
2.5 ADs issued by the State of Design can be found on the relevant websites of
concerning authorities. Example:

ADs for those products, ADs can be found on the relevant authorities websites.
(ii) For products, for which the UK is the state of design, the ADs issued by CAA,

3. Requirements
3.1 DCA will issue special ADs, in accordance with paragraph 2.1(b), only for the
following particular cases: -
(a) To introduce requirements which have a direct bearing on airworthiness or
operations but which, for a variety of reasons, e.g. specifically Myanmar climatic
conditions or experiences are unlikely to be the subject of direct action by the
State of Design.
(b) To introduce new requirements of DCA.
3.2 (a) The Appendix associated with this Notice provide brief details of all those
modifications and inspections issued as special Airworthiness Directives by the
DCA.
(b) Introduction of the Appendix will be re-issued at any time that the Appendix is
revised, to provide details of the current issue of each page in the Appendix.
4. Technical Responsibility
4.1 It is the responsibility of Chief Inspectors or Quality Assurance Managers and Aircraft
Maintenance Engineers to ensure that the accomplishment of any operational directive,
airworthiness directive, the mandatory modifications and/or inspections and any other
continued airworthiness requirement made mandatory by the State of Design and/or
the DCA for that particular aircraft within the periods specified.
4.2 An entry must be made in the appropriate log book or record, showing the date upon
which each mandatory modification and/or inspection and/or airworthiness directive
was complied with.
4.3 If, on the expiry of the specified period, the action defined in paragraphs 4.1 and 4.2 has
