National Transportation Safety Board spokesman Terry Williams said the pilot is scheduled to be interviewed soon.
The aircraft is registered to a Charles Lewis, of Gilford, N.H., according to the Federal Aviation Administration’s website, and New Hampshire State Police on Thursday identified the pilot as Lewis, 61, and the passenger as David Faxon. No hometown was immediately available for Faxon.
The two men were transported to the hospital — one airlifted — after the crash on Sunday. Both were expected to survive, according to initial reports after the crash.
Officials with the FAA are working alongside authorities at the NTSB to investigate the incident.
Among the factors investigators are looking into are the pilot’s record, the weather patterns in the area on the day in question and the maintenance of the plane, Williams said on Thursday.
Standard procedure calls for a preliminary report to be issued within seven to 10 days of the crash, but it will not include details about the cause of the accident, he said.
The two men were rescued from the Vermont side of the river near Harkdale Farms in Newbury, Vt., after the single-engine SeaRey plane crashed around 12:30 p.m. Few other details have been released.
The plane had a valid registration that doesn’t expire until 2021, the FAA reported.
The weather at the time of the crash was clear, according to the National Weather Service.
The plane was removed from the river on Monday and taken to a “secure location” for further investigation, Williams said.
