TRAPPER CREEK, Alaska - Two single-engine float planes collided as they flew near an Alaska lake and one of them crashed and burned, killing the four people aboard, authorities said. The second plane landed safely despite significant damage.

One plane, a Cessna 180, was destroyed by the impact and fire, Federal Aviation Administration spokesman Ian Gregor said.

"It was engulfed in flames on the ground," Alaska State Troopers spokeswoman Megan Peters said.

The crash around Amber Lake near Trapper Creek, 80 miles (130 kilometers) north of Anchorage, came nearly three weeks after another in-flight collision that remarkably left the 13 people aboard the two aircraft unhurt.

The second plane in Saturday's crash, a Cessna 206, sustained significant damage but was able to return to Anchorage International Airport and make an emergency landing.

Pilot Kevin Earp, 56, of Eagle River, was alone in the aircraft and uninjured, Peters said in a news release.

She said late Saturday that four bodies were recovered from the wreckage. Authorities initially said at least two people were killed.

The state medical examiner's office was working to identify the dead.

There was no immediate word on how the collision occurred.

On July 10, nine people aboard a Piper Navajo and four people in a Cessna 206 were uninjured when the planes collided. Both aircraft had minor damage but were able to land safely in Anchorage, with FAA spokesman Mike Fergus then describing the incident as "almost unheard of."
