## Probable cause

The pilot's failure to maintain adequate airspeed resulting in an inadvertent stall/spin of the airplane.

## Sequence of events

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

- Loss of control - in flight, maneuvering - aerial application
  - airspeed - not maintained, pilot in command (cause)
  - stall/spin - inadvertent, pilot in command
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - ground

## Analysis

During the aerial application flight, the pilot had aligned the airplane for the third swath when the airplane "snapped hard to the left and went into a spin."  During the recovery procedure, the airplane struck the ground at a 45 degree angle.  Structural damage was found throughout the airframe.

## Factual narrative

On July 29, 2002, at 1030 central daylight time, a Grumman G-164A, single-engine agricultural airplane, N48523, struck the ground following a loss of control while maneuvering near New Roads, Louisiana.  The airplane was owned and operated by Ewing Flying Service, LLC., of New Roads, Louisiana, under 14 Code of Federal Regulations Part 137.  The commercial pilot, sole occupant, received minor injuries, and the airplane sustained substantial damage.  Visual meteorological conditions prevailed for the aerial application flight, and a company visual flight rules (VFR) flight plan was filed.  The aerial application flight departed New Roads at approximately 1000.

On the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) the pilot reported that he had aligned the airplane for the third swath when the airplane "snapped hard to the left and went into a spin."  The 27-year old pilot stated that the airplane was about 450 feet above the ground (AGL) when the airplane made a complete spin and started into the second.  The pilot was successful in recovering the airplane from the spin; however, due to low altitude, the airplane impacted a soy bean field in a 45-degree angle.

Structural damage was found throughout the airframe.
