Narrative:
It has been revealed recently that an eo (engineering change order) which has us modify the APU ground stud has had problems with APU's not starting and arcing in this area. It was brought to my attention that in sep/xa/99, I performed this modification and possibly used hi-locks instead of rivets in this location which could lead to arcing. Because 6 months have passed since the installation, I do not remember the fasteners I used. The problem has been corrected and I have refreshed myself with FAA and company policy concerning airworthiness directives and know that any substitutions or deviations must be approved.
