Isle of Man Aircraft Registry

The Isle of Man Aircraft Registry registers aircraft under the M prefix. Its office is on the ground floor of Viscount House at Ronaldsway Airport in Ballasalla. The registry's tagline is safety with service.

The registry handles aircraft registration, changes to aircraft details and renewals. It also handles transitional aircraft, licence validations and deregistration. Mortgage services are offered, along with support for the Cape Town Convention and IDERA. The site also has a carbon offsetting service.

Flight operations and airworthiness are handled by separate specialist teams. The registry also covers occurrence reporting and the acceptance of type certificates. Its website has a library of forms and documents, and a page on charges and making a payment.

Customers have access to an online customer portal and digital certificates. The site includes a register search. Its Isle of Man Aviation Business Directory lists businesses on the island that serve the aviation sector.

The news page lists events in 2026, including Corporate Jet Investor Malta in May, the Farnborough International Airshow in July, and Corporate Jet Investor Asia in September. The blog covers topics such as ramp inspections on M registered aircraft, and a common misconception about tax, importation and aircraft registration.

The site shows logos for the International Civil Aviation Organization, the Isle of Man Civil Aviation Administration, and the Royal Aeronautical Society as a corporate partner. Contact is through team inboxes for registry services, airworthiness, flight operations, occurrence reports and ARDIS support.
