The airplane was examined on-scene by inspectors from the Federal Aviation Administration (FAA) with the assistance of a representative from Air Tractor. All major components of the airplane were found at the accident site. The transmission line was entangled around the empennage and tailwheel. Flight control continuity was established from the cockpit controls to the elevators and rudder. The aileron controls were damaged and did not exhibit any preimpact anomalies. The flap controls were continuous, and the flaps were set to 5°. The pilot's restraints were found unbuckled. No anomalies consistent with a preimpact failure or malfunction were observed with the airframe or the engine. 

Medical And Pathological Information

The Arkansas State Crime Laboratory, Little Rock, Arkansas performed an autopsy on the pilot. The cause of death was multiple blunt force injuries. According to the autopsy report, first responders noted that the pilot did not appear to have been wearing a safety helmet or pilot restraints.

The FAA's Bioaeronautical Sciences Research Laboratory, Oklahoma City, Oklahoma, performed toxicology testing on samples from the pilot. Testing was negative for carbon monoxide and ethanol. Testing detected acetaminophen, citalopram and its metabolite N-desmethylcitalopram, and pioglitazone in urine. Citalopram, N-desmethylcitalopram, and pioglitazone were also identified in heart blood.

Acetaminophen is a pain and fever medication available over the counter and commonly marketed as Tylenol; it is not impairing. Citalopram is a prescription antidepressant commonly marketed as Celexa. Pioglitazone is a prescription medication used to treat diabetes.

While citalopram is not generally considered impairing, its use indicates that the pilot was being treated for depression, which is associated with significant cognitive degradation, particularly in executive functioning. As a result, depression is a disqualifying condition for pilot medical certification. The FAA will consider a special issuance of a medical certificate to a depressed pilot after 6 months of treatment if the applicant is clinically stable on an approved medication.

Pioglitazone is not directly impairing, but the FAA requires regular additional evaluations of diabetic pilots to ensure their diabetes is properly controlled and they do not have neurologic, renal, or ophthalmologic complications of the disease that might impair their ability to safely fly an aircraft. If specific criteria are met for the control of this disease, a pilot may be issued a medical certificate.

Review of personal medical records from the pilot's endocrinologist showed that he had been diagnosed with type 2 diabetes mellitus in 2006. In 2009, he had brain surgery to remove a large tumor on his pituitary gland. As a result, he lost regulation of the hormonal systems usually controlled by the pituitary gland. He began to take replacement hormones for hypoadrenalism, hypothyroidism, hypogonadism, and diabetes insipidus immediately after the surgery. Over the ensuing years, the pilot developed peripheral neuropathy and kidney dysfunction from his chronic, poorly controlled diabetes mellitus. At one point, he burned his foot because he could not feel it, and he developed a right foot drop. The records indicated that the pilot refused to consider using insulin to treat his diabetes mellitus because it would not be allowed by the FAA.

At his most recent endocrinology visit in April 2016, the pilot's medications included: citalopram; desmopressin (a hormone that treats diabetes insipidus); glimepiride, metformin, pioglitazone, and Victoza to treat his diabetes mellitus; hydrocortisone (to replace cortisol); levothyroxine (thyroid replacement); and pregabalin (a potentially impairing medication used to treat chronic nerve pain due to diabetes).

One of the pilot's family members made a call to the FAA safety hotline in March 2016 reporting that the pilot was falling frequently and having trouble getting up afterward, taking "heavy duty psych meds," and having fits of rage where he would threaten to crash his airplane into a variety of targets. In April 2016, the family member made an email report to the FAA describing the pilot's medical conditions. The FAA requested information from the pilot in April 2016. This issue was being evaluated by the FAA at the time of the accident.
