One of the two pilots aboard an airplane carrying fuel reported there was a fire on the airplane shortly before it crashed and burned outside Fairbanks, killing both people on board, a federal aviation official said on Wednesday. The pilot had made radio contact about the in-fight emergency shortly after taking off, said Clint Johnson, head of the National Transportation Safety Board's Alaska regional office.

They were attempting to return to Fairbanks International Airport when they lost contact, he said. The plane crashed about 7 miles (11 kilometers) outside Fairbanks, hitting a steep hill and sliding down an embankment to the bank of the Tanana River. Alaska State Troopers say no survivors were found. The plane departed Fairbanks just before 10 a.m., loaded with 3,200 gallons (12,100 litres) of heating oil for Kobuk, an Inupiat village of less than 200 people located about 300 miles (480 kilometers) northwest of Fairbanks. Johnson said there was also about 1,200 gallons of aviation fuel aboard the C54D-DC Skymaster plane, a World War II-era airplane that had been converted to a freighter. It is difficult and expensive to get fuel to rural Alaska villages, which are remote and difficult to reach because of the state's limited road system.
