Aircraft
Flight was cleared for takeoff on Runway 08. As the throttles were raises to set takeoff power the crew received a level two alert 'ELEC Alerts'. After a brief moment on Runway 08 with ATC approval the crew decided to exit the runway to investigate the level two alert. Referring to the QRH the crew was instructed to contact aircraft Maintenance. After discussing the malfunction with aircraft Maintenance it was determined that we had a bad Electrical System Controller. Aircraft Maintenance instructed the crew to contact Maintenance Control to get a control number. After contacting Maintenance Control the crew received a control number for the inoperative Electrical System Controller. As the crew prepared to taxi for takeoff the level two alert 'ELEC Alerts' returned. After some troubling shooting with aircraft Maintenance it was determined that the number one IDG was bad. As directed by MEL 24-21-01 Integrated Drive Generators (IDG) inoperative; the number one IDG was disconnected. The MEL directed the crew to operative the electrical system in manual and the crew contacted Maintenance Control for control number. Flight departed with a deferred Electrical System Controller inoperative and the number one IDG deferred (disconnected) and arrived at our filed destination with no further incident or system malfunctions.
An MD-11 developed two separate electrical system malfunctions while taxiing for takeoff. On the first takeoff attempt the Electrical System Controller failed; on the second attempt an IDG failed.
