comments: Discussed situation, suspected thread damage on RA source. Decided to change to backup ADN and RA source. Moved RA source from installation carrier to shipment container, thread mated correctly inside shipment container. Reconsidered action and made new attempt to install RA source. Removed adapter on ADN and transferred source directly from the installation carrier into the ADN. Installed RA source succesfully.
