| Confidence Rating: |  Accident investigation report completed and information captured |
En route and during approach all cockpit display units blanked momentarily and a number of alerts were presented. During approach passing 1500 feet on the instrument landing system the autopilot and the autothrottle system also disengaged. A manual go-around was initiated and the information on the display units returned. During the following manual approach an unsafe gear warning appeared and a second go-around was performed. After contacting the company the gear was selected down successfully. The third approach and landing were uneventful.
CONCLUSION
This event demonstrated the vulnerability of an MD-11 electrical system featuring these unreliable power relays. Essential flight information was interrupted and autoflight capability was lost during a critical flight phase in instrument meteorological conditions. Further, consultation of the emergency checklist did not prove to be helpful in providing an effective solution for this problem.
