The ACE pass immediately followed the maintenance period. The ACE FOT was not notified of the antenna being red and called the station after the pass had started (1505z). DSN issued out a Flash Report at 1526z. A washer on a screw was causing a short-circuit at the antenna and was removed. The antenna returned to service at 1535z. DR#M105369 IMPACT: Activities delayed 35 minutes. The attitude maneuver was completed successfully.
