## Probable cause

The pilot's failure to attain adequate airspeed.  A tailwind was a contributing factor.

## Analysis

The pilot initiated a takeoff to the east from the last half of a one mile dirt road and after becoming airborne, the airplane cleared 10-foot high obstruction near the end of the road and then began descending.  The airplane impacted the ground in a sugar cane field and came to rest upright. The wind at the time was from the west-southwest and the pilot further stated that there was no mechanical failure or malfunction.

## Factual narrative

On July 17, 1998, about 1700 eastern daylight time, an Air Tractor 502, N9184R, registered to Air Crop Care, Inc., collided with terrain during takeoff from a dirt road near Clewiston, Florida.  Visual meteorological conditions prevailed at the time and no flight plan was filed for the 14  CFR Part 137 aerial application flight.  The airplane was substantially damaged and the commercial-rated pilot, the sole occupant, was not injured.  The flight was originating at the time of the accident.

The pilot stated that the fuel tanks were full and the hopper was loaded with 3,600 pounds of dry fertilizer; nearly 7/8 full.  He initiated a takeoff to the east using the second half of a mile-long dirt road.  The airplane became airborne and cleared a 10-foot-tall exhaust of a pump located at the end and slightly to the right of the runway centerline.  The flight continued but began descending, during which, the left wing of the airplane collided with sugarcane about 50 feet past the departure end of the runway.  The airplane yawed to the left coming to rest upright on a heading 180 degrees from the takeoff heading.  The pilot further stated that there was no mechanical failure or malfunction and at the time of takeoff, the wind was from the west-southwest at 2-3 knots.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - weather condition - tailwind (contributing factor)
  - airspeed - not attained, pilot in command (cause)
  - stall/mush
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - crop
