Objectives:

• The most obvious objective of an Airworthiness Division is to ensure design levels of reliability and operating safety of civil registered aircraft through promulgation and enforcement of highest achievable standards of airworthiness.

Importation of Aircraft into Myanmar

How do you prepare for Importation of Aircraft into Myanmar?

• Information based on the Department of Civil Aviation's Objectives, Regulations, and General Requirements for Myanmar Registration and Airworthiness certification or acceptance of civil aeronautical products imported to Myanmar.
• Owners or intending Owners/ Operator of aircraft are hereby notified that Technical Documents and Engineering and Performance Data submitted to the DCA in support of the importation, operation and maintenance of aircraft on, or intended to be on the Myanmar Register of Aircraft will be acceptable only if the information contained therein is expressed in the English language and in English terms and units.
• In the case of legal documents such as Type Certificate associated with related reports, Certificates of Airworthiness, Licences and Authorization, correct translation into English must be authenticated by the appropriate authority of the country of origin.
• The importer of any aircraft into Myanmar shall, before arrival of the said aircraft, submit one copy of all Manufacturer’s updated Publications pertaining to the Operation, Maintenance, Overhaul and Repair of the aircraft including engines, propellers and equipment to DCA Airworthiness Division. The importer shall make further arrangement for the supply of amendments to the above and modification and service bulletins as and when published.
• In the case of Commercial Transport aircraft for hire and reward, before certification, the owner will be obliged to provide the Airworthiness Division with full operational details. The obligation contained in above paragraph, shall cease only when the aircraft is transferred to another owner resident on the Myanmar in which case the new owner shall be responsible for the continuation of supply of the technical publications and bulletins detailed. The obligation shall cease only when the aircraft has been remove from the Register of Civil Aircraft.
• Prior to issue of a C of R and C of A for certain foreign manufactured aeroplanes which is the first of its type and Rotor craft or an Airship or Balloon, DCA may decide that a technical team will visit the manufacturer or the last owner to evaluate the aircraft for compliance with Myanmar Requirements.
• DCA General Requirements for Registration and Airworthiness Certifications of aircraft to be imported into Myanmar are stated in the Airworthiness Notices A/9.
• Any person /organization who wish to possess/operate the aircraft and decide to import and register any aircraft in Myanmar shall follow these steps :

1. Apply for allocation of registration marks to DCA
2. Submit Application for Certificate of Registration, CA form 56 together with the prove documents as specified in MCAR part 47 to DCA.
3. DCA will issue a certificate of registration upon meeting all the requirements for Registration specified in MCAR part 47.
4. Applicant must require for the Arrangement of Continuing Airworthiness Management of intended aircraft.
5. Based on type of the aircraft Applicant must require the Arrangement of Maintenance for intended aircraft.
6. Submit Application for Certificate of Airworthiness, CA form 62 together with the prove documents detailed in Airworthiness Notices A/10 to DCA.

How can get the Modification/Repair Approval from Regulating Authority?

• A Modification to an aeronautical product means a change to the type design which is not a repair. A modification can be classified as Major and Minor. Major modification means a type design change not list in the aircraft, aircraft engine or propeller specifications that might appreciable affect the mass, balance, structural strength, performance, power plant operation, flight characteristics, noise, fuel venting or other characteristics affecting the airworthiness of the product, or that will be embodied in the product using non-standard practices. A minor modification means a modification other than a major modification.
• A repair to an aeronautical product means a design change intended to restore it to an airworthy condition after it has been damage or subject to wear. A major repair means a design change which is intended to restore an aeronautical product to an airworthy condition where the damage being repaired might appreciably affect the structure strength, performance, power plant operation, flight characteristics, or other qualities affecting airworthiness or environmental characteristics or that will be embodied in the product using non-standard practices. A minor repair means a repair other than a major repair. Classification of Major and Minor modification / repair are described in Appendix of Airworthiness Notices A/4.

Which mean Approved data?

Data that can be used to substantiate major repairs/major modifications, derived from (but not limited to) the following:-

• Type Certificate Data
• Supplemental Type Certificate (STC) data, provided that it specifically applies to the item being repaired/altered
• Airworthiness Directives (AD)
• Airframe, engine, propeller manufacturer’s “DCA-approved” maintenance manuals or instructions.
• Component manufacturer’s manuals or instructions, unless specifically not approved or resulting in an alternation to the airframe, engine, and/or propeller.
• Major Repair or Modification/Alternation form, when the specified data has been previously approved.
• Structure Repair Manual (SRM), only as a source of approved data for a major repair, when it is a State of Design-approved document. Data that is minimum content, which includes the location on board the aircraft where the contact details, at which operational management can be contacted without undue delay, are listed, contained in an SRM that is not approved, can be used on a case-by-case basis if prior DCA approval is granted for that repair.
• Repair data, issued by a DCA delegated engineering authority holder.
• Service bulletin and letters or similar documents which are specifically approved by the state of Manufacturer.
• FAA Advisory Circular 43-13-1, Acceptable Methods, Techniques, and Practices-Aircraft Inspection and Repair, as amended.
• The detail requirements, procedures and application instructions are shown in Airworthiness Notices A/4.

 How do you perform civil aircraft for weighing? 

• All aircraft on the Civil Register of Myanmar shall be weighed when they are initially issued with a Certificate of Airworthiness.
• Aircraft, the Maximum Total Weight Authorized of 5700 kg and less, shall be reweighed at such time as the Department of Civil Aviation may require.
• Aircraft, the Maximum Total Weight Authorized of which exceeds 5700 kg, shall be reweighed within two years after the date of manufacture, and subsequent check weighing shall be made at intervals not exceeding five years, and at such times as the Department of Civil Aviation may require or at intervals specified in the Approved Maintenance Schedule or Approved Maintenance Program for that particular aircraft.

Weighing Procedures 

• Aircraft weighing shall be carried out under the control of a person authorized by an Approved Maintenance Organization. (Note._ Authorized person should have been adequately trained for the weighing purpose and has had adequate recent practical experience of the duties to be performed.) Aircraft shall be weighed on scales of a type approved. Each weighing scale shall have been calibrated by the manufacturer or manufacturer’s authorized firm within a period of one year prior to weighing any aircraft. Sufficient personnel and equipment, including scales shall be provided to satisfactorily carry out the weighing. The aircraft weighing intervals and weighing procedures are more detail described in Airworthiness Notices A/7.
