N4305DWsk Pzl Mielec M-18A

On February 15, 2013, about 1710 central standard time, N4305D, a PZL Mielec M-18A, single-engine airplane, was substantially damaged when it impacted the guy wire for a radio tower southeast of Jennings, Louisiana. The pilot was fatally injured. The airplane was registered to and operated by Riceland Aviation, Inc. Day visual meteorological conditions prevailed at the time of the accident. The aerial application flight was being conducted under the provisions of 14 Code of Federal Regulations Part 137 without a flight plan. The local flight had departed about 1650 from the Jennings Airport (3R7), Jennings, Louisiana.

According to Riceland Aviation, the pilot was applying the herbicide Round Up to a rice field southeast of 3R7. The wreckage of the airplane was found near a radio tower in a field where the airplane had been conducting aerial applications. An examination of a radio tower to the southwest of the main wreckage revealed damage to the number 7 and 8 guy wires on the east side of the tower.

Satloc data recovered from the accident airplane depicted the airplane having made multiple passes, consistent with spray passes, in the vicinity of the radio tower. The last two minutes of the recording depict eda spray path from north to south, followed by a right turn to the west and then a course reversal to the east. The flight path depicted the airplane just to the south of the radio tower, with a flight path from the southwest to the northeast; the recorded decrease in altitude is consistent with an approach for the next spray pass to the north. The altitude increased at the end of the field and the airplane reversed course again. The flight path reversed to the south and then a right turn, back around to the north for a second pass along the same course as the previous pass. The airplane had just initiated a descent for the southwest to northeast pass when the recording ended.

The pilot, age 52, held a commercial pilot certificate with airplane single and multiengine land ratings. He was issued a second class airman medical certificate on February 28, 2012. The certificate contained the limitation "must have available glasses for near vision."

According to the National Transportation Safety Board Pilot Operator Aircraft Accident Incident Report Form submitted by the operator, the pilot had logged 19,325 hours of flight experience; 10,627 hours were in the make and model of the accident airplane. The pilot had successfully completed the requirements of a flight review on September 19, 2011.

According to Riceland Aviation, the pilot had not attended formal training for agricultural operations and had obtained all of his knowledge and experience through on-the-job training. The pilot had attended the Professional Aerial Applicators' Support System (PAASS) training provided by the National Agricultural Aviation Association in 2013. The pilot also held a chemical applicators license as required by the State of Louisiana.

The accident airplane, a PZL Mielec M18-A (serial number 1Z022-19), was manufactured in 1991. It was registered with the Federal Aviation Administration (FAA) on a special airworthiness certificate for restricted agriculture and pest control operations. A Pratt & Whitney PT6A-65B turbo-prop engine powered the airplane. The engine was equipped with a 4-blade, Hartzell propeller.

The airplane was registered to and operated by the Riceland Aviation Inc., and was maintained under an annual inspection program. A review of the maintenance records indicated that a 100-hour inspection had been completed on October 11, 2012, at an airframe total time of 6,999 hours.

The closest official weather observation station was Jennings Airport (3R7), Jennings, Louisiana, located 3.5 nautical miles (nm) northwest of the accident site. The elevation of the weather observation station was 23 feet mean sea level (msl). The routine aviation weather report (METAR) for 3R7, issued at 1715, reported, wind 360 degrees at 7 knots, visibility 10 miles, sky condition, scattered clouds at 7,000 feet, temperature 17 degrees Celsius (C), dew point temperature 5 degrees C, altimeter 30.11 inches.

According to the United States Naval Observatory, Astronomical Applications Department Sun and Moon Data, the sunset was recorded at 1759 CST and the end of civil twilight was 1823 CST.

The airplane wreckage was located in a dry rice field just northeast of the radio tower. The accident site was at an elevation of 15 feet mean sea level.

A small piece of the left wing was wrapped around one guy wire. Torn and bent metal from the left wing and the outboard section of the left wing were located directly below the east tripod of guy wires. Damage to the inboard section of the left wing, at the separation point, was consistent with a wire strike.

The main wreckage came to rest just north of the east tripod of guy wires. The main wreckage included the inboard portion of the left wing, the right wing, the empennage, and the engine. The spray booms, the propeller assembly, and bent and torn metal were located in the short debris field and ground scar directly adjacent to the main wreckage.

An examination of the airframe, engine, and related systems, conducted by the responding FAA inspector, revealed no anomalies.

The radio tower, which was owned by Global Tower Partners, was located in the northwest corner of the target field. The radio tower was guyed by 8 wires in a tri-pod configuration. The tower stood approximately 480 feet in height and was painted red and white. The radio tower was depicted on the Houston Visual Flight Rules Sectional Chart as a cluster of two towers to the southeast of Jennings, Louisiana. The broadcast tower was marked in accordance with guidance outlined in FAA Advisory Circular 70/7460-1K and the requirements found in the Federal Communications Commission Regulation 47 CFR §§ 17.21-17.50.

According to officials at Riceland Aviation Inc., the pilot was familiar with the field and had flown that field at least 15 times in the previous spray season. There were no ground crews present during the aerial application flight. They stated that it appeared that the pilot had finished spraying the field and was "dressing up around the tower."

The accident airplane was equipped with Hemisphere AgJunction Satloc G4 control system designed to control the application of chemicals during aerial application flights. The Satloc G4 operates a cockpit mounted lightbar guidance system and a real-time graphic moving map display providing visual guidance to the pilot. Flow rates can be pilot selected or based on mapping. The unit was sent to the National Transportation Safety Board (NTSB) Vehicle Recorders Lab in Washington, D.C. for download. The log files downloaded from the unit were dated between January 8, 2013, and February 15, 2013. The last recording, which included the accident flight, lasted over two hours and was not corrected for the local time zone.

The Calcasieu Parish Coroner's Office and Forensic Facility performed the autopsy on the pilot on February 16, 2013, as requested by the Jefferson Davis Parish Coroner's Office. The autopsy concluded that the cause of death was due to the "multiple injuries sustained in an airplane crash" and the report listed the specific injuries.

The FAA's Civil Aerospace Medical Institute, Oklahoma City, Oklahoma, performed toxicological tests on specimens that were collected during the autopsy (CAMI Reference #201300071001). Results were negative for carbon monoxide and ethanol. Tests of the urine detected 40.8 ug/ml of Salicylate; a metabolite of aspirin.
