## Analysis

THE RIGHT WINGS OF THE AG OPERATOR'S BI-PLANE COLLIDED WITH THE GROUND SUPPORT CABLES OF A 322 FT HIGH MICROWAVE TOWER WHILE ON A BASE LEG FOR LANDING. THE RIGHT WINGS SEPARATED & THE ACFT CRASHED & BURNED KILLING THE PLT. THE 25000 HR PLT KNEW OF THE TOWER AS HE HAD BEEN FLYING IN THE IMMEDIATE AREA FOR OVER 20 YEARS. A WITNESS STATED THAT THE ACFT WAS FLYING INTO THE RISING MORNING SUN & THE PLT MAY HAVE BEEN BLINDED BY THE SUN'S GLARE.

## FAA reports on this event (1)

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

- [Accident 19860710072139A](https://openairdocs.org/incident/19860710072139A), Jul 10, 1986: Scwzer G164B, Sidon, MS, Destroyed. Aircraft hit guy wires while landing at an agricultural strip. Low sun angle may have obscured pilots vision.

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.
