American Airlines Flight 383 was a nonstop flight from New York to Cincinnati on November 8, 1965. The aircraft was a Boeing 727-123 aircraft with 62 people on board. The aircraft crashed on approach to the Cincinnati/Northern Kentucky International Airport. Only four individuals survived, including three passengers, and one flight attendant.

Aircraft

The aircraft involved was a Boeing 727-100, registration number N1996, c/n 18901/153. The first flight of this aircraft was on June 15, 1965. It was delivered to American Airlines on June 28, 1965. At the time of the accident the total airframe hours were 938. The aircraft was powered by three Pratt & Whitney JT8D-7 engines.

Events leading to the crash

The flight was delayed for 20 minutes in New York but the flight itself was uneventful. At 18:45, the crew called Cincinnati tower for an ETA of 19:05. The weather was fine near the airport except for thunder clouds developing northwest of the airport across the Ohio River valley. The aircraft approached the airport from the southeast and turned its heading to north to cross the Ohio River. It turned west after crossing to the northern shore of the Ohio River, intending to make a final turn to southeast after crossing the Ohio River (which runs from northwest to southeast) again to the southern shore of the river. After that final turn, the aircraft would line up with the runway 18 of the airport to make the final approach. The pilots were attempting to make the landing on visual.

Crash

The aircraft flew into thick cloud and thunderstorm after flying into the northwest of the airport. It descended more rapidly than it should have, without either pilot in the cockpit noticing. The airport is situated at an altitude of 853 feet (260 m) and the aircraft had descended to the level of 553 ft (169 m) above the airport while it was still about 5 mi (8.0 km) northeast of the airport. It descended to just 3 ft (per altimeter) above the airport while it was about 3 nm north of the airport. Its correct altitude should have been just below 1,000 ft (300 m) at that time. It continued its descent into the Ohio River valley while crossing the river back to the southern shore. When it made its last turn to the southeast to line up with the runway, it flew into the wooded slopes of the valley 3 km north of the runway threshold in poor visibility, at an altitude of -225 ft (i.e. 225 ft (69 m) below the runway's altitude). It then exploded and was engulfed in flames.

Investigation

The Civil Aeronautics Board conducted the subsequent investigation. The investigation concluded that the aircraft was working normally and fully under the control of the pilots at the time of the crash. The aircraft was not equipped with a cockpit voice recorder. The flight data recorder showed the aircraft descended through 500 feet (150 m) in the last 42 seconds before impact, a normal rate of descent for the landing phase of operation. It was later believed that the following factors might have contributed to the crash:

• Lights from the houses in the Ohio River valley, located 400 feet (120 m) below the altitude of the airport, may have conveyed an illusion of runway lights.
• The flight crew may have been confused about their true altitude, due to misinterpretation of the aircraft's drum-type altimeter after descending through 0 feet (relative to the airport altitude), or they may have had their hands full controlling the plane in severe weather and simply failed to notice the readings on the altimeter.
• A late departure from New York and the deteriorating weather at Cincinnati may have put pressure on the flight crew.
• Despite the rapidly deteriorating weather conditions, the flight crew chose to make a visual approach to the runway.

Notable passengers

One of the survivors was Israel Horowitz, an American record producer.

Robert Arthur Bargeron (born November 4, 1916) was a casualty. He was vice president of Health and Welfare for the United PaperMakers and PaperWorkers AFL CIO and left behind a wife, Constance Lydiard Bargeron, and four young children, Willow, Winter, Hunter and Heather of Blandford, Massachusetts.
