Registering your Aircraft in Singapore

An aircraft shall not fly unless it bears the nationality and registration marks as required by the law of the country in which it is registered. The registration marks to be borne by the aircraft shall comply with the Aviation Specifications 12 - Nationality Mark and Registration Mark.

For your aircraft to fly in Singapore, you will need to register it under the Singapore Register, an ICAO Contracting State, or another State that has an air service agreement with Singapore.

If you do not have a Certificate of Registration (CoR), you can submit your application to CAAS, Flight Standards Division on eSOMS.

In the event eSOMS is not available, please contact us and complete Form CAAS(AW)39 (Application for Registration of Aircraft).

For more information, please refer to the Air Navigation (47 – Aircraft Registration) Regulations 2026.

Transferring the Right to De-register your Aircraft

The Convention on International Interests in Mobile Equipment (Cape Town Convention) and Protocol to the Convention on International Interests in Mobile Equipment on Matters Specific to Aircraft Equipment (Aircraft Protocol) establish an international legal framework relating to the creation, priority, and enforcement of security and leasing interests in aircraft equipment.

Singapore has enacted the International Interests in Aircraft Equipment Act 2009 and International Interests in Aircraft Equipment Regulations 2026 to fulfil its commitments as a Contracting State to the Cape Town Convention and Aircraft Protocol.

Under the laws, you (as the holder of a certificate of registration) may apply to CAAS to record an Irrevocable De-registration and Export Request Authorisation (IDERA) to transfer the right to de-register the aircraft to an authorised party. The authorised party may then apply to CAAS to record a Certified Designee Confirmation Letter (CDCL) to transfer the right to de-register the aircraft to a certified designee.

What is an Irrevocable De-registration and Export Request Authorisation (IDERA)?

An IDERA is a document that is submitted to CAAS to record an authorised party under Article XIII of the Protocol to the Convention on International Interests in Mobile Equipment on Matters specific to Aircraft Equipment. Once CAAS records an IDERA, “the authorised party” becomes the sole person who can:

  • Request the deregistration of the aircraft from CAAS, and
  • Request the physical export of the aircraft from its current location.

What is a Certified Designee Confirmation Letter (CDCL)?

A CDCL is a document that is submitted to CAAS to record a certified designee, as appointed by “the authorised party” under the IDERA. Once CAAS records a CDCL, “the certified designee” becomes the sole person who can exercise the rights of the IDERA.

Application Process:

  • For an application to record an IDERA, please refer to form CAAS-IIAE-1-01.
  • For an application to record a CDCL, please refer to form CAAS-IIAE-1-02.
  • For an application to cancel a recorded IDERA, please refer to form CAAS-IIAE-1-03.
  • For an application to cancel a recorded CDCL, please refer to form CAAS-IIAE-1-04.

Important to Know:

  • The submitted IDERA and CDCL applications must follow the format in the forms respectively.
  • CAAS records IDERAs and CDCLs for Singapore registered aircraft only.

For more details on the procedure of submitting an IDERA and CDCL, or cancelling a recorded IDERA and CDCL, please refer to the latest revision of Advisory Circular AC IIAE-1, or visit our FAQs.
