Brief Description: Continued stabilator service bulleting rework
Completed steps 11-13 page 2 of 8 in service bulletin.
Step 11: Removed the HS-1213A and HS-1213B Hinge Brackets, and HS-1210 Hinge Stops from the Stabilator Assembly (see KAI Page 09-07). Step 12: Discarded the HS-1213A and HS-1213B Hinge Brackets. Step 13: For all the bolts removed in the previous two steps carefully check for cracks around all bolt holes, nutplate attach holes and the area in between the fastener holes and the top/bottom edge of the spar. Since airplane has never flown there were no issues. Step 14 skipped.
Completed steps 15-17 page 4 of 8 in service bulleting Step 15: Punched out the mandrels, then drilled out #30 the three rivets common to the HS-1202 Fwd Spar and each of the HS-1212 Inspar Ribs (hidden from view per Figure 4. Step 16: Clecoed each HS-01231D Stabilator Hinge Doubler to HS-1202 Fwd Spar using the three rivet locations just drilled out in the previous step so that the bolt holes align (the part is not symmetrical). Match-Driledl #30 the remaining #40 holes in HS-01231D into HS-1202. Disassembled the parts and cleaned out any drill shavings. Step 17: Riveted both HS-01231D Stabilator Hinge Doublers to the HS-1202 Fwd Spar as shown in Figure 4.
