A306, vicinity Nagoya Japan, 1994

Summary

On 26 April 1994, the crew of an Airbus A300-600 lost control of their aircraft on final approach to Nagoya and the aircraft crashed within the airport perimeter. The Investigation found that an inadvertent mode selection error had triggered control difficulties which had been ultimately founded on an apparent lack understanding by both pilots of the full nature of the interaction between the systems controlling thrust and pitch on the aircraft type which were not typical of most other contemporary types. It was also concluded that the Captain's delay in taking control from the First Officer had exacerbated the situation.

Description

On 26 April 1994, an Airbus A300-600R (B1816) being operated by China Airlines on a scheduled international passenger flight from Taipei to Nagoya as CI 140 and on final approach to destination in night Visual Meteorological Conditions (VMC) crashed within the airport perimeter out of control and was destroyed by the impact and a post crash fire. 264 of the 271 occupants were killed and the remaining 7, all passengers, were seriously injured.

Investigation

An Investigation was carried out by the Japan Aircraft Accident Investigation Commission (JAAIC). Data from both the Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR) were successfully downloaded in support of the Investigation.

Once it had been established that there was no evidence to indicate that the accident could be attributed in any way to a lack of continued airworthiness or to any aspect of aircraft loading, attention was focused on the actions of the crew and their control of engine thrust and aircraft pitch with particular focus in the A300-600R Automatic Flight System (AFS) and the crew interface with it during the latter stages of the accident approach.
