DUBLIN, May 30 (Reuters) - Ireland's High Court is to

begin hearing a dispute around insurance claims for aircraft

stuck in Russia on June 11, a week later than scheduled, after

parties in the case asked for additional time to prepare, a

court spokesman said on Thursday.

Lessors are suing dozens of insurers around the world for

billions of dollars after more than 400 planes were unable to

leave Russia due to Western sanctions in response to Moscow's

invasion of Ukraine that forced the termination of their leases.

The world's number two and three lessors, SMBC and Avolon,

as well as BOC Aviation ( BCVVF ), CDB Aviation, Nordic Aviation

Capital and Carlyle Aviation Partners are pursuing their claims

in Ireland, where more than 60% of the world's leased aircraft

are owned or managed.

The world's biggest aircraft lessor, Irish-based AerCap ( AER )

, is pursuing its insurance claims through London's High

Court.

The Irish case is to be held at a special venue as no court

in Ireland is large enough to accommodate the 180 lawyers

involved, Justice Denis McDonald told a hearing last year. The

case had been due to begin on June 4.
