## Probable cause

PREMATURE PULL UP FROM AN AERIAL APPLICATION SWATH RUN RESULTING IN A COLLISION WITH AN ELECTRICAL TRANSMISSION LINE.

## 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
  - object - wire,transmission
  - pull-up - premature, pilot in command (cause)
  - clearance - not maintained, pilot in command (cause)

## Analysis

WHILE CONDUCTING AERIAL APPLICATION, THE PILOT FLEW UNDER A POWERLINE DURING A SWATH RUN, PULLED UP EARLY, AND STRUCK THE POWERLINE FROM UNDERNEATH.  THE AIRCRAFT FLIPPED OVER AND STRUCK THE GROUND NOSE LOW AND INVERTED.

## 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 19910527017429A](https://openairdocs.org/incident/19910527017429A), May 27, 1991: Scwzer G164A, Ville Platte, LA, Substantial damage. Struck powerlines and crashed inverted during pullup for a turn around. Pilot beleived he had cleared lines.

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.
