PARIS, Sept 4 (Reuters) - Airlines will likely be told

there is no immediate need for global checks on the Airbus

A350-1000, ending days of uncertainty after an engine

emergency prompted Cathay Pacific to review its fleet, two

people familiar with the matter said.

Barring last-minute changes as investigators examine parts

from an A350 that returned to base on Monday, Airbus and engine

maker Rolls-Royce are expected to move to allay wider safety

concerns in their first briefings to carriers on Thursday.

Airbus declined comment and referred queries to Hong Kong

investigators, who could not be reached. Rolls-Royce and Cathay

Pacific did not immediately respond to requests for comment.

Although the stance suggests the incident is increasingly

being seen as isolated, it is too early to rule out further

findings or analysis that may eventually require action by other

airlines, the people said, asking not to be identified.

A final decision rests with regulators. It was not

immediately clear whether the European Union Aviation Safety

Agency (EASA) had formally endorsed a decision to refrain from

recommending fleet action, which can cause delays and downtime.

"We have no further comment at this stage as we are still

completing our assessment," an EASA spokesperson said.
