A pilot with limited flight experience navigated into deteriorating weather and icing conditions without a flight plan, resulting in a controlled flight into terrain incident involving a tower guy wire.

What happened

The pilot, who had accumulated only 55 hours of total flight time, received a weather briefing indicating unfavorable flying conditions along the route to the destination. Despite these warnings, he departed without filing a flight plan. As the aircraft approached the destination area, located approximately eight miles south, the weather rapidly deteriorated. The ceiling dropped to 200 feet and visibility decreased to one mile, with ice accumulating on the windshield.

While attempting to maintain orientation by following a highway below, the pilot encountered a 180-foot tower. At an altitude of 177 feet above ground level, the aircraft struck a guy wire supporting the structure. The impact caused the pilot to lose control of the aircraft, which subsequently crashed into a nearby field.

The investigation

Examination of the wreckage and review of the flight path confirmed that the aircraft collided with a guy wire attached to a tower. The low altitude of the impact relative to the tower height indicated that the aircraft was flying below the obstruction while attempting to navigate visually along the highway.

Findings

Contributing factors included unfavorable weather conditions and icing on the windshield, which degraded visibility and aircraft performance. The pilot's decision to fly without a flight plan into known deteriorating weather, combined with limited experience, played a significant role in the accident. The failure to maintain adequate terrain clearance while following ground features resulted in the collision.

Safety message

Pilots must strictly adhere to weather minimums and avoid flying into known icing conditions without appropriate equipment and training. Filing a flight plan and obtaining accurate, up-to-date weather briefings are critical safety practices, especially for less experienced pilots navigating in marginal visual meteorological conditions.

Probable cause

The pilot's failure to maintain terrain clearance due to deteriorating weather and windshield icing while flying without a flight plan.
