Examination of the accident site revealed that the helicopter came to rest on its right side in a wheat field (the wheat crop was about 3 inches tall) owned by the pilot's business. Three ground scars, consistent with main rotor blade strikes, were observed adjacent to the main wreckage. Fragmented plexiglass was scattered between the ground scars and main wreckage. Separated sections of the main rotor blades were located within a 75-ft diameter of the main wreckage; the main rotor blades were fragmented, bent, deformed, and their root sections remained attached to the rotor hub. No evidence of contact with any adjacent structures or power lines was observed.

The lower forward fuselage was crushed aft and upward. The tailboom was intact, and the horizontal stabilizer was bent. No damage was noted to the tail skid. The forward landing gear skid tubes were fractured, and the left forward skid tube was separated and located in the debris field. The left forward door was separated, the right forward door and rear cabin doors were damaged and partially fragmented. The forward seat belts and shoulder harnesses were unlatched. The helicopter was not equipped with an emergency locator transmitter.

Flight control continuity was established from the cockpit flight controls to the swashplate and tail rotor system. Drivetrain continuity was established from the engine to the main transmission and tail rotor systems.

The engine remained attached to the engine mount and secured in the airframe. Thumb compression was noted on all cylinders, and mechanical continuity throughout the engine was established. The magnetos and ignition leads produced spark when engine crankshaft was rotated. 

Medical And Pathological Information

An autopsy was performed by South Plains Forensic Pathology, P.A., Lubbock, Texas. The cause of death was blood loss due to visceral injuries due to blunt force injuries, and the manner of death was an accident.

The autopsy also described significant heart disease. The heart weighed 610 gm and both the ventricles were dilated; the left ventricle was described as having severe hypertrophy, but no measurements were given. There was very severe coronary artery disease in the native arteries, but the grafts were all described as patent. A stent was identified, but not further described. Sections of the myocardium revealed scarring from old heart attacks in the left ventricle. Microscopy of the heart showed myocyte hypertrophy with interstitial and perivascular fibrosis. There were areas where adipose and fibrotic tissue replaced normal cells.

Toxicology testing performed by the Federal Aviation Administration's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, identified no ethanol in the vitreous. In addition, salicylate (a metabolite of aspirin) was found in urine, losartan was found in cavity blood and liver, and clopidogrel was identified in liver tissue. As stated above, none of these are considered impairing.

Donald "Don"  Oppliger
1949-2017


Donald "Don" Oppliger, 68, of Amarillo, TX, died Sunday, June 4, 2017, in Dimmitt, TX. 

Don was born April 7, 1949, in Columbus, NE, to Edward and Edna Oppliger.

He graduated from Columbus High School in Nebraska and attended the University of Nebraska.

He married Joi Christopher on Aug. 14, 1976, in Blair, NE. 

Don owned and operated the Don Oppliger Companies, which include feedlots, farms, and ranches spread across roughly 150,000 acres in Texas, New Mexico, and Nebraska.

He began his business in 1980 with rented farmland in Hereford and quickly began expanding it with the purchase of a 15,000 head feedlot in Farwell.

Don then acquired a 35,000 head feedlot in Clovis, NM, in 1991 and later purchased his first Nebraska farm in Lincoln County, NE, on which he built at 55,000 head feedlot, which he later expanded to 70,000 head. 

In the last decade, Don acquired multiple ranches across Eastern and Western Nebraska and additional farmland and feedlots in Nebraska and Texas. 

His integrated and diversified operations also included a dairy and a trucking company. 

Despite the complexity of the operation, Don somehow managed to track the many details of his businesses in his head and a small notepad he kept in his shirt pocket.

He loved cattle and enjoyed checking on his many pastures and feedlots from the cockpit of his plane or helicopters. 

Aside from attending Nebraska Cornhusker games, farming and flying were his favorite hobbies. 

"People say he died doing what he loved," Ben Oppliger said.   "That's really true." 

Although Oppliger was a successful and wealthy landowner, he also was down-to-earth and always willing to make time for a visit, said Joe Herrod, who owns property neighboring Oppliger's west of Sutherland.

Outside of the industry, few people knew he was such a large operator, Herrod added. 

"He was a wonderful neighbor, just an aw-shucks kind of guy," he said.  "It's really a shame." 

He was preceded in death by a son, Grant Oppliger; and a sister, Lori Prill.

Survivors include his wife, Joi Oppliger, of Amarillo; a son, Benjamin Oppliger and wife Katie, of Amarillo; a granddaughter, Madison Oppliger, of Amarillo; three sisters: Rita Peters and husband Don of Elkhorn, NE; Diane Thompson and husband Joe, of Lincoln, NE; and Phyllis Olson and husband Ralph, of Columbus, NE.

THE FAMILY WILL RECEIVE FRIENDS from 6-7pm Wednesday, June 7, 2017, at the funeral home. 

SERVICES will be at 1pm Thursday, June 8, 2017, at Polk Street United Methodist Church with Dr. Burt Palmer, senior pastor and the Rev. Kevin Deckard, associate pastor, officiating.

Burial will follow at 4pm, in Farwell Cemetery in Farwell, TX. Sign the online guestbook at www.boxwellbrothers.com

Don Oppliger, whose massive agribusiness the Oppliger Companies is headquartered in Amarillo, was killed in a helicopter crash Sunday in Castro County. He was 68.

Documents from the Castro County Sheriff’s Office said they were called just after 8 a.m. Sunday by the Parmer County (N.M.) Sheriff’s Office after they were notified by an employee of one of Oppliger’s ranches concerning a helicopter crash in the southwestern area of Castro County.

Authorities discovered a crash site in a wheat field about a half mile south of the 200 block of County Road 623. Castro County Sheriff’s Office and the Texas Department of Public Safety conducted an investigation of the scene and identified Oppliger has the pilot of the helicopter.

He was pronounced dead at the scene by Castro County Justice of the Peace Oreda Campbell, and an autopsy has been ordered.

No other people were believed to be with Oppliger at the time of the crash.

The investigation into the crash in ongoing and is being conducted by the Federal Aviation Administration and the National Transportation Safety Board.

Oppliger started his business career in 1980 when he rented farmland in Hereford that grew corn from the Frito-Lay Company, and then expanded it with a 15,000 head feedlot in Farwell, according to the Oppliger Companies website. The cattle-feeding operation thrived under the watch of Oppliger, who relocated it to the Texas-New Mexico border.

Oppliger then acquired a 35,000 head feedlot near Clovis, N.M., in 1991, as well as more irrigated farmland to supply the new lot, before expanding again to Lincoln County, Neb., in 1998 with a 55,000 head feedlot that he later expanded to more than 70,000.

In the last decade, the Oppliger Companies have acquired multiple ranches across western Nebraska, additional farmland in Nebraska and Texas, and two feedlots located near our larger farming operations.

The company currently operates 10 locations across the Texas Panhandle, eastern New Mexico and Nebraska, including locations in Texline, Dalhart, Farwell and Dimmitt.

The company’s website says it has more that 55,000 acres of irrigated farmland and is headquartered in downtown Amarillo on Polk Street.

Attempts to reach the Oppliger Companies for comment went unreturned.
