"Army Air Corps engineers are on their way to recover the helicopter and there will be an investigation," she said.
Both crew members on board were uninjured.
The Apache was taking part in Nato's Operation Joint Warrior training exercise and was flying to the airfield at Kinloss Barracks in Moray from West Freugh near Stranraer, Dumfries and Galloway.
Troops from 16 Air Assault Brigade were carrying out an aviation assault to capture the airfield as part of the exercise.
