Investigation Summary
Flight 280/D was a Military Air Command charter transporting soldiers from California to Georgia. During the stopover approach at Ardmore, the crew encountered marginal weather with low ceilings and light rain. After missing an ADF instrument approach to Runway 08, they attempted a visual circling approach to Runway 30. During this maneuver, the Captain, Reed Pigman, who was also the airline's president, suffered coronary insufficiency. Autopsy results showed severe arteriosclerosis and calcified arteries. Crucially, investigators found that Pigman had been taking heart medication (Peritrate) and diabetes medication (Orinase) for years, yet he had falsified his FAA medical applications since at least 1957 to hide these disqualifying conditions. The First Officer's injuries suggested he was attempting to fly the aircraft at impact, but the sudden incapacitation of the Captain at low altitude left insufficient time for a recovery.
Final Conclusions
The Civil Aeronautics Board (CAB) determined the probable cause was the incapacitation of the pilot-in-command due to coronary insufficiency at a critical point during a visual circling approach conducted under instrument flight conditions. A significant contributing factor was the pilot's deliberate falsification of medical records to obtain a first-class medical certificate despite having known, disqualifying cardiovascular disease and diabetes.

Crew Experience
Captain
Founder and President of the airline; suffered fatal heart attack during approach.
First Officer
Attempted to take control prior to impact.

Held a commercial pilot certificate.
Systems & Failure Modes
ADF (Automatic Direction Finder)
The primary navigation tool used for the initial instrument approach to Runway 08, which the crew missed.
FAA Medical Certification
The regulatory system failed to detect the Captain's disqualifying health conditions due to his active concealment and falsification of records.
Interesting Facts
- 01The aircraft involved was the same Lockheed Electra that carried The Beatles during their 1964 U.S. tour.
- 02The Captain, Reed Pigman, was the founder and president of American Flyers Airline.
- 03Autopsy evidence indicated the First Officer had his hands on the controls at impact, while the Captain did not.
- 04The Captain had been treated for heart disease since 1957 and diabetes since 1962, but denied both on all FAA physicals.

Safety Actions & Advisories
Medical Record Scrutiny
The accident highlighted the need for more rigorous verification of pilot medical histories and the potential for pilots to hide disqualifying conditions from aviation medical examiners.
