Computer-Related Incidents with Commercial Aircraft

The Eastern Airlines L1011 Common Mode Engine Failure

5 May 1983

Synopsis Eastern Airlines Flight 855, a Lockheed L1011 aircraft, suffered a common mode failure of all three engines after departure from Miami. The aircraft returned and landed safely at Miami - apparently only just. The incident is not computer-related, but illustrates maintenance-induced common mode failures such as happened to Aeroperu Flight 603. The full NTSB Report (175K + GIFs + JPEGs) has been digitised and prepared by Hiroshi Sogame of the Safety Promotion Committee of All-Nippon Airlines for inclusion here. We are very grateful to Mr. Sogame for his work.
