## Probable cause

THE PREMATURE LIFTOFF BY THE PIC AND HIS FAILURE TO ATTAIN PROPER RATE OF CLIMB.  FACTORS RELATING TO THE ACCIDENT WERE THE GUSTY CROSSWIND WEATHER CONDITIONS, THE FAILURE OF THE PIC TO USE ALL AVAILABLE RUNWAY, AND TRANSMISSION WIRES.

## 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
  - weather condition - crosswind (contributing factor)
  - weather condition - gusts (contributing factor)
  - all available runway - not used, pilot in command (contributing factor)
  - lift-off - premature, pilot in command (cause)
  - object - wire,transmission (contributing factor)
  - proper climb rate - not attained, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PIC INITIATED A TAKEOFF FROM A RUNWAY INTERSECTION, LIFTED OFF PREMATURELY, AND THE ACFT SETTLED BACK ONTO THE RUNWAY.  THE PIC CONTINUED THE TAKEOFF AND LIFTED OFF AT THE END OF THE RUNWAY.  THE ACFT SETTLED SLIGHTLY AFTER TAKEOFF AND BEGAN A SHALLOW CLIMB.  WHEN THE ACFT APPROACHED POWER LINES AT AN ALTITUDE TOO LOW TO CLEAR THE WIRES, THE PILOT ATTEMPTED TO TURN TO AVOID IMPACT.  THE LEFT WING STRUCK POWER LINES LOCATED ABOUT 2500 FT FROM THE END OF THE RUNWAY, AND THE ACFT DESCENDED UNCONTROLLED AND IMPACTED THE GROUND.

## 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 19930521014629A](https://openairdocs.org/incident/19930521014629A), May 21, 1993: Univar 1081, Brigham City, UT, Destroyed, 1 fatal. Lifted off prematurely. Settled. Lifted end runway. Shallow climb. Saw wires. Banked to avoid. Wing hit wires.

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.
