Investigation Docket - National Transportation Safety Board:
Location: Salem, South Dakota
Accident Number: CEN19LA053
Date and Time: January 13, 2019, 14:25 Local
Registration: N75191
Aircraft: Piper PA28
Aircraft Damage: Substantial
Defining Event: Medical event
Injuries: 1 Fatal
Flight Conducted Under: Part 91: General aviation - Personal
Analysis
About 15 minutes after departing on a cross-country flight in day visual meteorological conditions, the pilot contacted air traffic control to report that he was having chest pain and blacking out, and was having difficulty controlling the airplane. The controller continued to communicate with the pilot for about 20 minutes before radio contact was lost. The wreckage was subsequently located in a field. Examination did not reveal any preimpact anomalies that would have precluded normal operation of the airplane.
The pilot's Federal Aviation Administration medical certificate expired about 10 weeks before the accident. He had begun but not completed the requirements for operation under BasicMed. Autopsy of the pilot identified coronary artery disease including 80% stenosis of the left anterior descending coronary artery and 50% stenosis of the right coronary artery and diagnosed an acute myocardial infarction (heart attack). It is likely that the sudden, impairing effects of the heart attack and associated severe chest pain resulted in the pilot's loss of airplane control while attempting to land in a field, and its subsequent impact with terrain.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The incapacitating effects of an acute myocardial infarction (heart attack), which resulted in the pilot's loss of airplane control and impact with terrain.
Findings
Personnel issues Cardiovascular - Pilot
Personnel issues Aircraft control - Pilot

On January 13, 2019, about 1425 central standard time, a Piper PA-28-181 airplane, N75191, was substantially damaged when it impacted terrain about 6 miles south of Salem, South Dakota. The private pilot was fatally injured. The airplane was owned and operated by the pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed in the area and no flight plan was filed for the cross-country flight, which originated from Mitchell Municipal Airport (MHE), Mitchell, South Dakota, and was destined for Mary Skie-Lincoln County Airport (Y14), Tea, South Dakota.
About 15 minutes after departing, the pilot contacted Sioux Falls Approach Control and stated that he was having chest pains, was blacking out, and was having difficulty maintaining control of the airplane. About 1411, radar track data indicated the airplane was traveling southeast. The airplane then maneuvered/circled for about 6 minutes, briefly headed northwest briefly and began maneuvering/circling again. The controller continued to communicate with the pilot for about 20 minutes before radio contact was lost about 1425; the track data ended about the same time, about 2 miles southwest of the accident site. The wreckage was subsequently located in a field about 30 nautical miles east-southeast of the departure airport.

The wreckage was located in a harvested crop field. Review of information and photographs provided by local law enforcement revealed that all major components of the airplane were present at the site. The airplane main wreckage was found resting upright in the field. The cockpit was crushed and the empennage was facing north. A debris field, wheel tracks, and ground scars in the field indicated that the airplane contacted the ground about 600 to 800 ft north of where it came to rest. The wreckage was removed from the scene and was placed in a secure building.
The wreckage was subsequently examined by an FAA inspector and airframe manufacturer's representative. The examination revealed no preimpact anomalies that would have precluded normal operation of the airplane.
Medical and Pathological Information
The McCook County Coroner coordinated the pilot's autopsy at the Sanford Health Pathology Clinic, Sioux Falls, South Dakota. The autopsy indicated that the pilot's cause of death was multiple blunt force injuries due to an airplane crash due to acute myocardial infarction due to atherosclerotic cardiovascular disease. The autopsy identified coronary artery disease, including 80% stenosis of the left anterior descending coronary artery and 50% stenosis of the right coronary artery.
Toxicology testing performed at the FAA Forensic Sciences Laboratory identified valsartan in liver and muscle, ranitidine in muscle, and amlodipine in liver and muscle.
Amlodipine is a calcium channel blocker heart medication used in the treatment of hypertension. Ranitidine is used in the treatment of gastric acid secretion. Valsartan is an angiotensin II receptor antagonist indicated for treatment of high blood pressure, of congestive heart failure, and post-myocardial infarction.
The pilot's personal medical records indicated that he had well-controlled hypertension and occasional visits for respiratory infections. The pilot requested his primary physician fill out the FAA physician attestation form for BasicMed and the physician did so, attesting to the pilot's ability to safely operate an aircraft. The medical records also included the history form filled out by the pilot during this process; however, the FAA had no record of receiving the pilot's BasicMed documents.
