Narrative:
I was assigned the #2 engine inspection on the l-chk for aircraft YYY on the night of nov/xx/97. One of my cards was to change the ignitors and inspect the cables. After I performed the operational check of the ignitors and they passed, I noticed my safety wire job on the cannon plugs to the excitor boxes were sloppy, and decided to rewire them. I pulled both cannon plugs off to inspect the integrity of the safety wire holes then was called to the other side of the engine to help another mechanic. I ended up helping him for longer than planned and forgot to put the cannon plugs back on the excitors. The plane left the hangar for the terminal and the #2 engine would not start. They had to deplane the passenger and send the plane back to the hangar, resulting in a lengthy delay.

Title: A DC10-10 INCURRED A LENGTHY DELAY DUE TO UNABLE TO START #2 ENG CAUSED BY THE IGNITION EXCITOR BOX'S CONNECTORS DISCONNECTED.
Narrative: I WAS ASSIGNED THE #2 ENG INSPECTION ON THE L-CHK FOR ACFT YYY ON THE NIGHT OF NOV/XX/97. ONE OF MY CARDS WAS TO CHANGE THE IGNITORS AND INSPECT THE CABLES. AFTER I PERFORMED THE OPERATIONAL CHK OF THE IGNITORS AND THEY PASSED, I NOTICED MY SAFETY WIRE JOB ON THE CANNON PLUGS TO THE EXCITOR BOXES WERE SLOPPY, AND DECIDED TO REWIRE THEM. I PULLED BOTH CANNON PLUGS OFF TO INSPECT THE INTEGRITY OF THE SAFETY WIRE HOLES THEN WAS CALLED TO THE OTHER SIDE OF THE ENG TO HELP ANOTHER MECH. I ENDED UP HELPING HIM FOR LONGER THAN PLANNED AND FORGOT TO PUT THE CANNON PLUGS BACK ON THE EXCITORS. THE PLANE LEFT THE HANGAR FOR THE TERMINAL AND THE #2 ENG WOULD NOT START. THEY HAD TO DEPLANE THE PAX AND SEND THE PLANE BACK TO THE HANGAR, RESULTING IN A LENGTHY DELAY.
