Some of the unexpected tasks were to un-sieze the rudder fin post from the boom, repair broken ribs inside the fin and to replace the fibreglass around the rear boom support cross-member (which had been cut away to give extra tip clearance for the prop). While it was apart, Bruce had the tailplane mounting tubes crack-tested and did the common Shadow upgrade of fitting UHMWPE bushes inside the boom to prevent further wear on these mounting tubes.
