recommendations for remediation based on applicable standards specified by the Accord. The
scope of this initial electrical safety inspection was limited to the review and identification of major
electrical safety issues. The inspection did not include identification of minor deficiencies, which will
be further addressed as part of follow-up inspections.
Table below summarizes the major electrical safety issues identified during the inspection.
Recommendations have been provided to address each issue.
An implementation schedule shall be developed by the factory to remediate each of the
findings. The specific timing of improvements, including any requested extensions due to
