MH370: State of Registry

The Boeing 777-200-ER operated by Malaysia Airlines for flight MH370 on Saturday, 8 March 2014 was registered in Malaysia as 9M-MRO. The State of the Registry is therefore Malaysia.


The term State of Registry is defined by the International Civil Aviation Organisation (ICAO) in the Annex 13 to the Convention on International Civil Aviation, Aircraft Accident and Incident Investigation which is generally referred to simply as Annex 13.

The word State is used to refer to a nation which is a signatory to the Convention on International Civil Aviation.

The responsibilities of the State of Registry are defined in Annex 13 and expanded in the ICAO publication Doc 9756 Manual of Aircraft Accident and Incident Investigation.


State of Registry
The State on whose register the aircraft is entered.
Note: In the case of the registration of aircraft of an international operating agency on other than a national basis, the States constituting the agency are jointly and severally bound to assume the obligations which, under the Chicago Convention, attach to a State of Registry. See, in this regard, the Council Resolution of 14 December 1967 on Nationality and Registration of Aircraft Operated by International Operating Agencies which can be found in Policy and Guidance Material on the Economic Regulation of International Air Transport (Doc 9587).
