N8719S

HISTORY OF FLIGHT

On June 20, 2002, approximately 0040 Pacific daylight time, an Air Tractor AT-301 agricultural airplane, N8719S, was destroyed when it impacted power lines and terrain while maneuvering near Westmorland, California. The commercial pilot, the sole occupant of the aircraft, was fatally injured. The airplane was registered to and operated by Val-Air Co. Inc. of Brawley, California. Visual meteorological conditions prevailed, and no flight plan was filed for the 14 CFR Part 137 aerial application flight. The local flight departed a private airstrip near Brawley at 0010.

In written statements provided to the NTSB investigator-in-charge, the owner reported the pilot was spraying a 70 acre cotton field from west to east, starting on the north side of the field. Power lines, approximately 40 to 60 feet high, bordered the south side of the field. One of the ground flagmen stated that on the next to the last pass flying to the east, the pilot pulled up out of the field, made a left turn, then a right turn to reverse direction. During the right turn the airplane's left wing struck the power lines, caught on fire and impacted a paved road which bordered the field on the south. The airplane came to rest inverted and oriented in a southwest direction.

PERSONAL INFORMATION

At the time of the accident the pilot held a commercial pilot certificate for single engine land, and instrument airplane. The pilot reported on his most recent airman medical application a total time of 11,000 flight hours, with 300 flight hours in the last 6 months. The operator reported that the pilot's most recent biennial flight review occurred on June 29, 2000, and that this was the first season that the pilot had worked for the operator. In telephone interviews with the NTSB investigator-in-charge, previous operators for whom the pilot had been employed indicated the pilot had several years of night aerial application experience.

FAA records indicated that the pilot was issued a second-class medical certificate on March 25, 2002, with no waivers or limitations.

AIRCRAFT INFORMATION

The airplane, a restricted category Air Tractor AT-301, serial number 301-0178, was powered by a Pratt & Whitney R-1340 AN-1 engine rated at 600 horsepower. Maintenance records indicated that the airplane's last inspection, an annual inspection, was completed on March 11, 2002. The airframe's total time was approximately 10,803 hours.

WRECKAGE AND IMPACT INFORMATION

A Federal Aviation Administration airworthiness inspector from the San Diego, California, Flight Standards District Office responded to the accident site. The inspector reported the accident site was approximately 3/10 of a mile east of the field being sprayed, and that the airplane came to rest in an inverted position on an asphalt road which bordered the south side of the field. The nose of the airplane was oriented in a southwesterly direction.

Aircraft damage consisted of the left wing, left horizontal stabilizer, left elevator, and the right landing gear separated from the airplane. The engine remained attached to the airframe. The propeller remained attached to the engine and a 3/4 inch steel power line wire was wrapped around the engine and hub of the propeller. A post-impact fire had consumed the airplane from the cockpit forward, as well as the left side of the fuselage from the rear of the cockpit to the left horizontal stabilizer.

A subsequent examination by the NTSB investigator-in-charge confirmed flight control continuity.

MEDICAL AND PATHOLOGICAL INFORMATION

An autopsy of the pilot was conducted by the Imperial County Coroner, Brawley, California, on June 22, 2002. According to the autopsy report, the pilot's cause of death was attributed to blunt impact injuries of the head, neck, and cheek.

The FAA Civil Aeromedical Institute (CAMI), Oklahoma City, Oklahoma, conducted toxicology testing on the pilot. According to the postmortem toxicology report, results were negative for carbon monoxide, cyanide, ethanol and illegal drugs.

ADDITIONAL INFORMATION

An inspector from the FAA San Diego Flight Standards District Office released the wreckage to the aircraft operator on June 21, 2002. The wreckage was then transported to a salvage facility located in Phoenix, Arizona.
