Ten people were killed Sunday when a seaplane crashed at the Soldotna Airport in Alaska, according to the National Transportation Safety Board.

Clint Johnson, chief of the NTSB in Anchorage, told NBC's Alaska affiliate that all nine passengers and one pilot aboard the plane were killed after the it crashed, though it is unclear whether the accident happened during takeoff or landing.

The NTSB has sent a team to Alaska to investigate the crash.

The Soldotna Police Department said the accident took place around 11:20 a.m. (3:20 p.m. ET), and emergency responders arrived to find the small plane engulfed in flames. 

“First responders are attempting to remove the remains of the people that were on board as well as to identify the victims and notify family members,” Soldotna police said in a statement. 

An FAA spokesman said the plane was a de Havilland DHC-3 Otter operated by Rediske Air.

Soldotna is south of Anchorage on the Kenai Peninsula.
