The returns from the dealers on the existing 185-1046 Fan Spider As have been analyzed. The existing 185-1046 Fan Spider As functions at an acceptable level.

The existing 185-1046 Fan Spider As are balanced by a combination of applying balancing weights and trimming the blades. The unequal blades on the fan spider assembly have the appearance of being out-of-balance. The existing 185-1046 Fan Spider As will function normally.
