To operate an aircraft in Singapore, it must first be registered under one of the following:

  • an ICAO Contracting State

  • a State that has an air service agreement with Singapore

For aircraft registered in Singapore, the nationality and registration marks must comply with Aviation Specifications 12 - Nationality Mark and Registration Mark.

Aircraft owners who wish to register their aircraft in Singapore have to apply for a Certificate of Registration with CAAS.

For more details on the requirements, refer to Regulation 5 of the Air Navigation (47 — Aircraft Registration) Regulations 2026.

Who can apply

The owner of an aircraft who is one of the following can apply:

  • the Singapore Government

  • a citizen of Singapore

You are encouraged to engage CAAS early to discuss your Certificate of Registration application to facilitate timely processing.

How to apply

Phase 1: Pre-application

Notify CAAS of your intention to register an aircraft in Singapore.

An application for a Certificate of Registration should be followed by applications for a Certificate of Airworthiness and a Noise Certificate.

Phase 2: Formal application

Fill in and submit your application on eSOMS together with the required documents. The required documents are:

  • details of the owner and operator

  • details of the aircraft and engines

  • documents supporting Reduced Vertical Separation Minima (RVSM) operations for the aircraft

  • evidence that the aircraft’s nationality and registration marks comply with Aviation Specifications 12 - Nationality Mark and Registration Mark

  • evidence that the information on the aircraft owner’s name plate is accurate

  • any other document or report that CAAS may require

Phase 3: Document evaluation

CAAS will review the application and documents submitted. During this phase, CAAS may request clarifications from the applicant.

Phase 4: Demonstration and inspection

CAAS may request an aircraft inspection or documentary evidence to ensure that regulatory requirements are met.

Phase 5: Certification

Upon approval, CAAS will notify the applicant and the Certificate of Registration will be available in eSOMS. Each certificate includes a QR code for authenticity.

Registration alone does not permit you to fly your aircraft in Singapore. You must also satisfy the applicable operating requirements. For details, refer to:
