Analysis

The propeller contacted a telephone pole at a height 30 feet above the ground during an aerial application flight. The result of the impact was a loss of airplane control, followed by the airplane descending to impact the terrain. The airplane was flying to the east, into the sun at the time of the accident.

Factual narrative

On May 17, 1998, at 0830 central daylight time, a WSK PZL Mielec M-18A, N2284B, operated by Kratz Aerial Ag Service, Inc., collided with a telephone pole during an aerial application maneuver. The accident occurred near Dawson, North Dakota. The commercial pilot received serious injuries. The airplane was substantially damaged. The 14 CFR Part 137 flight was operating in visual meteorological conditions without a flight plan.

Post accident inspection of the accident site by an Inspector from the Federal Aviation Administration Flight Standards District Office revealed the propeller on N2284B contacted the telephone pole at a height of about 30 feet above the ground. The propeller was "severely" damaged and twisted according to the inspector. The airplane impacted the terrain after it collided with the telephone pole. The airplane was traveling to the east into the sun at the time of the accident.

The pilot does not remember any event surrounding the accident.
