Narrative:
After crossing the MONDI intersection inbound for an ILS runway 05 approach, the captain felt that a proper descent was not possible due to a strong tailwind and their present altitude. They turned and proceeded outbound to loose altitude. The crew then established themselves again on the inbound course at an airspeed of approximately 120 knots. Around 300 feet the plane descended rapidly, crashed onto the surface of a frozen cove, slid onto marshy terrain and stopped about 500 feet short of the runway.
PROBABLE CAUSE:
weather condition .. windshear
CONTRIBUTING FACTORS:
weather condition .. low ceiling
