ALVA, Oklahoma - We're learning more about a small plane crash in Alva last month that killed two men.

The trouble started when a piece of equipment on the plane popped up.

A preliminary NTSB crash report reveals that the aircraft then hit power lines and trees that were about 3,000 feet away from the runway at a nearby airport.

David Chael passed away at the scene of the crash and Cory Washburn died a few days later.
