TIME OF COMPLIANCE: At or before the next service intervention or regularly scheduled maintenance event, but not to exceed the next one hundred (100) hours’ time-in-service from the effective date above. PURPOSE: ICON is committed to designing, manufacturing, delivering, and supporting a high quality Light Sport Aircraft, providing a level of safety well beyond expectations. This Service Bulletin is to provide instructions on how to install a new design wing inboard roll bellcrank to eliminate an interference condition between the roll socket and the roll bellcrank rod end detailed in SB-090817 rev B. Not all aircraft have this condition, so it is important to inspect each aircraft for applicability. This service bulletin, when complied with, supersedes SB-090817 rev B and eliminates the reoccurring inspections of the bellcrank to roll socket interface.

Assemble the inboard roll bellcrank components as shown in Figure 3 (if not already assembled from ICON). It is permissible to re-use hardware from the previously removed bellcrank except the 98410A110 clip. The MS27644-3 bearing will require a press fit. Once press fit into the bellcrank, ensure the bearing smoothly rotates. If it does not smoothly rotate contact ICON for further assistance. 2. Reinstall the inboard roll bellcrank using the retained hardware. Tighten bellcrank AN23-17 bolt to 19inlb. See Figure 1. 3. Adjust the length of the inboard push rods to 85.575” center of rod end to center of rod end by adjusting the pushrod rod ends equally, then tighten the jamb nut to 60 in-lb. Ensure that both rod ends have enough thread protrusion by visually inspecting for threads through the witness holes on the rod ends. Note: The provide push rod length provided is intended as a starting point for the rigging process, the outboard rod end and will likely need to be adjusted slightly in a step 6 below if the rigging pin cannot be easily inserted.
