Air Illinois Flight 710
On the night of October 11, 1983, the Hawker Siddeley HS 748 operating the flight crashed near Pinckneyville, Illinois due to the flightcrew's mismanagement of electrical generator and distribution problems.Roughly 20 minutes after takeoff, the crew shut off excess lights in the cabin, but did not further reduce the electrical load on the aircraft's battery.The captain's decision was adversely affected by self-imposed psychological factors which led him to assess inadequately the aircraft's battery endurance after the loss of generator power and the magnitude of the risks involved in continuing to the destination airport.Contributing to the accident was the airline management's failure to provide and the FAA's failure to assure an adequate company recurrent flight crew training program which contributed to the captain's inability to assess properly the battery endurance of the aircraft before making the decision to continue, and led to the inability of the captain and the first officer to cope promptly and correctly with the aircraft's electrical malfunction."[citation needed] The investigation revealed the captain, considered an "average pilot," was a "one-man operation" and did not welcome input from the co-pilot and was in a hurry to return to Carbondale after being on duty all day.
