On August 6, 1989, a Cessna 188A (registration N188TV) operated by Otterson, Robert S. was involved in an aviation accident near Valley City, ND. Investigators recorded the probable cause as: INADEQUATE VISUAL LOOKOUT BY THE PILOT. THE POWER LINE WAS A RELATED FACTOR. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft struck power line wires at approximately 35 feet above ground level after completing a swath run, resulting in an inverted impact with the ground. The pilot's medical certificate had previously been denied.
What happened
The aircraft was engaged in low-level operations, specifically completing a swath run, when it collided with the wires of a large power line. The collision occurred at an altitude of approximately 35 feet above ground level (AGL). Following the impact with the wires, the aircraft rolled inverted and subsequently struck the ground approximately 270 feet beyond the location of the power line.
Findings
An examination of the pilot's records revealed that their previous application for a medical certificate had been denied. This administrative status was noted in relation to the event, though no specific mechanical failure or weather condition is detailed in the available source material regarding the immediate cause of the collision with the wires.
