What happened
The aircraft was engaged in a business flight when it collided with a guy wire attached to a radio tower. The incident occurred approximately three miles east of Bloomfield, Missouri. At the time of the accident, instrument meteorological conditions prevailed, creating low visibility and cloud cover.
Witnesses on the ground observed that the low clouds obscured the top of an 80-foot tall grain elevator located on their farm. This obstruction likely contributed to the difficulty in visually identifying the tower structure and its associated guy wires during the flight.
The investigation
A post-accident examination was conducted to determine the point of impact. The inspection of the radio tower's guy wire system revealed specific damage consistent with an aircraft strike. Investigators identified damage to one of the wires at an altitude of 260 feet above ground level (AGL). This finding confirmed the location where the aircraft made contact with the obstruction.
Findings
The primary contributing factor was the N30755 striking a guy wire while flying in poor weather. The presence of instrument meteorological conditions reduced visual references, making it difficult to avoid man-made structures like radio towers and grain elevators. The witness account regarding the obscured grain elevator highlights how low cloud bases can hide vertical obstacles that might otherwise be visible under clearer skies.
Safety message
Pilots operating in instrument meteorological conditions must remain vigilant for man-made structures, particularly radio towers and grain elevators, which may not be visible due to low cloud ceilings or fog. Adherence to instrument flight rules and reliance on navigation aids are critical when visual references are compromised.
