Unsafe Condition
A pivot pin outboard spacer that has been found to not be set correctly flush against the horizontal stabilizer pivot bearing and outboard washer due to a misaligned pivot pin lockring. The unsafe condition, if not addressed, could result in decreased lateral load capacity, which could cause the loss of pivot pin retention parts and lead to loss of the horizontal stabilizer and loss of continued safe flight and landing.
