[edit] Aircraft

The aircraft involved was a Boeing 727-123, registration number N1996, c/n 18901/153. The first flight of this aircraft was in 1965. At the time of the accident the total airframe hours were 938. The aircraft was powered by three Pratt & Whitney JT8D-7 engines.

The crew was pilots Captain Daniel J. Teelin, Captain William J. O’Neill, and Flight Engineer John T. LeVoie.

[edit] 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 a ETA of 19:05. The weather was fine near the airport except thunder cloud 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.

[edit] The 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 the altitude of 853 ft and the aircraft had descended to the level of 553 ft above the airport while it was still about 5nm northeast of the airport. It descended to just 3 ft (per altimeter) above the airport while it was about 3nm north of the airport. Its correct altitude should have been just below 1000 ft 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 3km north of the runway threshold in poor visibility, at an altitude of -225 ft (i.e. 225 ft below the runway's altitude). It then exploded and was engulfed in flames.

[edit] 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. It was later believed that the following factors might have contributed to the crash:

Under poor visibility in rain at night, the light from houses in the Ohio River valley might have confused the pilots as runway lights while in fact they are in the valley and locate below the altitude of the airport.
The altimeter on the aircraft might have confused the pilots of their true altitude once the aircraft had descended through 0 ft (relative to the airport), since the altimeter is supposed to be read differently after it descended into negative territory.
The pilots might have been busily adjusting flight controls to maintain the flight stability under severe weather and omitted the readings on the altimeter.
Mistakes by pilots might have been prompted by the delay in departing New York, and by the crew’s anxiety to beat the weather into Cincinnati.
