## Probable cause

the pilot's inadequate preflight planning and preparation. A factor in the accident is the downdraft.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with object, takeoff - initial climb
  - object - wire,transmission
  - weather condition - downdraft (contributing factor)
  - preflight planning/preparation - inadequate, pilot in command (cause)

## Analysis

THE PILOT REPORTED THAT HE TOOK OFF IN A WESTERLY DIRECTION FROM A PRIVATE, GRASS STRIP THAT WAS BORDERED BY WIRES AND TREES AT THE WEST END. HE SAID THAT THE AIRPLANE REACHED AN ALTITUDE OF APPROXIMATELY 50' ABOVE THE GROUND AND WOULDN'T CLIMB ANY HIGHER.  HE FEELS THE AIRPLANE WOULDN'T CLIMB ANY HIGHER DUE TO A DOWNDRAFT CREATED BY A WESTERLY FLOW OF WIND OVER THE TREES LOCATED AT THE WEST END OF THE RUNWAY. THE AIRPLANE COLLIDED WITH THE WIRES AT THE WEST END OF THE FIELD AND CRASHED. NO PREIMPACT MECHANICAL PROBLEMS WITH THE AIRPLANE WERE REPORTED BY THE PILOT.

## Factual narrative

On June 27, 1993, about 1800 central daylight time, a home built airplane, N200D, sustained substantial damage when it collided with wires during the initial climb from takeoff from Wilke Field,near Omro, Wisconsin.  The solo private pilot received serious injuries.  Visual meteorological conditions prevailed for the local 14 CFR Part 91 flight.

The pilot reported he took off to the west from the private, 1,300' grass strip. He states that upon reaching 50 feet, the airplane refused to climb any higher, and that he was rapidly approaching wires located at the end of the runway.  He attempted to go under the wires, but was unable to avoid striking them.  The pilot wrote in his report to the NTSB that he did not notice any decrease in power or RPM on takeoff, and that he believes the airplane was incapable of climbing any higher due to a down draft created by the westerly flow of wind over the trees located at the west end of the runway.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
