Analysis

The pilot had completed applying insecticide to the main area of the field and was 'trimming the field' when the airplane struck a power line. While trying to recover the pilot inadvertantly stalled the airplane and impacted the ground. The cockpit, hopper, and engine were consumed by a post crash fire.

Factual narrative

History of flight

On July 21, 1994, approximately 0915 central daylight time, a Schweizer AG-Cat G-164B, N6617Q, was destroyed while maneuvering near Foules, Louisiana. The commercial pilot was fatally injured. Visual meteorological conditions prevailed for the aerial application flight.

According to a witness, the pilot had completed applying insecticide to the main area of a field and was "trimming the field" when the airplane struck a power line. The pilot applied power, the airplane executed a climb, then descended straight down "wing over wing" to ground impact.

Aircraft information

A review of the airframe and engine records did not reveal any anomalies or uncorrected maintenance defects.

Wreckage and impact information

The initial ground scar was on a measured heading of 070 degrees. The aircraft came to rest 5 feet to the left of the initial ground scar on a measured magnetic heading of 040 degrees. The cockpit, hopper, and engine were destroyed by a post impact fire.

A power line was found down 125 yards from the initial impact scar. A piece of the top left wing tip was found below the repaired power line. See enclosed wreckage diagram. The left diagonal strut top fitting had a gouge approximately the same diameter as the downed power line. The left top aileron outside of the diagonal strut top attaching fitting, had scraping and rub marks.

Examination of the airplane and engine did not disclose any mechanical problems. Due to the extent of damage, flight control continuity could not be established.

Medical and pathological information

The autopsy was performed by pathologist David R. Steckler, M.D. at the Natchez Medical Center, Natchez, Mississippi. Toxicological findings were negative.

Additional data

The wreckage was released to the owner.
