## Probable cause

THE PILOT'S MISJUDGMENT OF THE CLEARANCE BETWEEN THE AIRPLANE AND THE ELECTRICAL TRANSMISSION WIRE. A FACTOR WAS THE HAZY VISIBILITY.

## Sequence of events

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

- In flight collision with object, maneuvering - aerial application
  - distance - misjudged, pilot in command (cause)
  - object - wire,transmission
  - weather condition - haze/smoke (contributing factor)
- Forced landing, descent - emergency

## Analysis

THE PILOT REPORTED THAT HE WAS CONDUCTING SPRAY OPERATIONS.  VISIBILITY WAS REDUCED TO ABOUT 3 MILES BY HAZE AND IT WAS DUSK. ON PULL-UP FROM A SWATH RUN, HE SAID, THE AIRPLANE'S DISTANCE FROM THE TOP WIRE OF A CROSS COUNTRY POWER LINE WAS MISJUDGED. THE LANDING GEAR CAUGHT THE WIRE AND A FORCED LANDING ENSUED. CONTACT WITH THE WIRE AND THE FORCED LANDING RESULTED IN SUBSTANTIAL DAMAGE TO THE AIRPLANE.

## 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 19910731030859A](https://openairdocs.org/incident/19910731030859A), Jul 31, 1991: Cessna A188B, Monroeville, AL, Substantial damage. Pulled up from spray runway and struck top wire of powerline causing crash. Wires hard to see in haze.

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.
