Hoist helicopter per R66 MM § 7-20.
Refer to R66 MM Figure 32-7 and R66 Illustrated Parts Catalog (IPC) Figure 32-11. Remove and retain two C944-3, C944-5, and C944-4 float retainer strips from each skid tube and extension.
Carefully position detached portion of one pop-out float to access aft strut attachment hardware.

Do not kink inflation hose.
Remove and discard hardware securing aft skid shoe to skid tube. Retain skid shoe.
Place a support under aft end of skid tube. Remove sealant, bolts, and washers securing aft strut assembly to skid tube. Remove skid extension.
Clean interior of skid tube. Insert appropriate new F014-7A or F014-7B skid extension with damper (see R66 SL-22) and align fastener holes.
Position skid shoe and loosely install (4) A142-1 screws (provided). Install strut attachment hardware. Standard torque bolts per R66 MM § 20-32. Secure A142-1 skid shoe screws.
Repeat steps 3 thru 7 on opposite side.
Remove skid tube support(s), lower helicopter, and remove lifting fixture (or rope) from main rotor hub.
Cover bolt heads of outboard bolts securing struts to skids with B270-1 sealant to prevent chafing float. Touch up paint at mating surfaces of skid extension and skid. Allow sealant and paint to dry.
