May 16 (Reuters) - United Airlines said on

Thursday the U.S. Federal Aviation Administration has permitted

the carrier to restart its certification activities, including

new aircraft and routes.

The airline's certification activities were suspended after

the FAA said in March it was increasing its oversight of United

following recent safety incidents. The aviation regulator said

it would initiate a formal evaluation to ensure the

Chicago-based carrier was complying with safety regulations.

"We will continue to see an FAA presence in our operation as

they review our work processes, manuals and facilities," United

Airlines said in a statement.

The airline delayed the start of two new international

routes last month, citing a pause on some certifications by the

FAA.
