Narrative:

I and my partner replaced the #1 engine integrated drive generator on the evening of oct/xx/96. When I came to work today, I found out that the aircraft returned to the field account of the #1 integrated drive generator failed. Previous maintenance found one of the main power lead connections from the aircraft to the generator had a loose nut and was arcing and burned. My partner insists that he tightened all of the power cable lug nuts. How that nut got loose I do not know. We completed the integrated drive generator installation per the maintenance manual up to the point where the integrated drive generator gets svced with oil. We wrote a work card to complete the integrated drive generator installation starting at the servicing of it with oil through to the completion of the job. Next shift completed the installation of the #1 integrated drive generator.

Narrative: I AND MY PARTNER REPLACED THE #1 ENG INTEGRATED DRIVE GENERATOR ON THE EVENING OF OCT/XX/96. WHEN I CAME TO WORK TODAY, I FOUND OUT THAT THE ACFT RETURNED TO THE FIELD ACCOUNT OF THE #1 INTEGRATED DRIVE GENERATOR FAILED. PREVIOUS MAINT FOUND ONE OF THE MAIN PWR LEAD CONNECTIONS FROM THE ACFT TO THE GENERATOR HAD A LOOSE NUT AND WAS ARCING AND BURNED. MY PARTNER INSISTS THAT HE TIGHTENED ALL OF THE PWR CABLE LUG NUTS. HOW THAT NUT GOT LOOSE I DO NOT KNOW. WE COMPLETED THE INTEGRATED DRIVE GENERATOR INSTALLATION PER THE MAINT MANUAL UP TO THE POINT WHERE THE INTEGRATED DRIVE GENERATOR GETS SVCED WITH OIL. WE WROTE A WORK CARD TO COMPLETE THE INTEGRATED DRIVE GENERATOR INSTALLATION STARTING AT THE SVCING OF IT WITH OIL THROUGH TO THE COMPLETION OF THE JOB. NEXT SHIFT COMPLETED THE INSTALLATION OF THE #1 INTEGRATED DRIVE GENERATOR.
