President Carter believes that the Concorde supersonic jet transport should be permitted to land at New York's Kennedy Airport, press secretary Jody Powell said yesterday.

It was the first time that Carter has explicitly endorsed New York as a landing site. However, the President has said on several occasions tha the supports the decision of the Ford administration, which permitted the Anglo-French jetliner to fly to Washington and New York for a 16-month test period.

Kennedy Airport has been closed to the plane by the airport-owning New York port Authority on the grounds that the Concorde would be too noisy. The Carter administration, like the Ford administration before it, has said landing rights were a prerogative of the local authority, not the federal government. Dulles Airport, where the Concorde lands hers, is owned and operated by federal government.

On Monday, the Port Authority removed reconsideration of the Concorde question from the agenda of its monthly meeting, scheduled for Thursday. That action was taken, the authority said, so that its technicians might meet with British and French experts to discuss noise abatement techniques for the Concorde.

That meeting is scheduled for 3 p.m. today at Kennedy Airport. There is no chance the Concorde will be discussed at the full board meeting Thursday, the authority said.

The British and French have insisted that, given the chance, they can meet Kennedy's noise standards. They insist that their repeated attempts to tell the Port Authority what they wanted to do have been ignored.
