cal POC of the recommended disposition instructions. The logistical POC will contact the unit and provide
final disposition instructions.
(2) The logistical POC will contact the unit POC if additional information on prior spindle and main
rotor blade history is necessary to complete the evaluation of the discrepant part and its impact on attached
components.
c.  If disposition instructions have not been received from the logistical POC within 10 flight hours of

to replace the affected attaching components in order to return the aircraft to flyable status. In this event,
annotate records to reflect the removal and replacement of the main rotor spindle and main rotor blade where
the discrepant expandable pin was installed. Hold the removed components pending disposition instructions.
