A plane which crashed near Fife Aiport last year, resulting in the death of the pilot, lost power because of water getting into the engine, investigators have said. Nicholas Denison-Pender, 50, from Perthshire, died in the crash near Kinglassie on 23 December.

The release of the reports followed a news conference by NTSB officials who said Federal Aviation Administration procedures that governed the airspace near Reagan National Airport before the crash allowed for an “intolerable risk” that increased the chance of midair collisions,

Investigators issued their preliminary report Tuesday in the probe into the devastating crash between an American Airlines plane and a U.S. Army Black Hawk helicopter.
