FUSELAGE AND VERTICAL TAIL / SEAWINGS™ 11-9
CHANGE C1 ICON A5 / MAINTENANCE MANUAL
2. Inspect all bushings in the Seawings™ and interfacing pins bonded to the Seawings™ for secu-
rity, corrosion and wear. Remove any deficient bushing or pin.
3. If it is necessary to replace a ICA010317 bushing in the Seawings™ tip, proceed as follows:
a. Use Plexus MA830 adhesive.
b. Prepare all bond surfaces (bushing and carbon structure) by first cleaning with a cloth and
isopropyl alcohol, then abrading with 120-180 grit aluminum oxide emery paper. Shiny bond
surfaces should be dulled by sanding, but avoid unnecessary sanding of the carbon struc-
ture or excessive clearances could result.
c. Mix adhesive in accordance with manufacturer’s instructions.
d. Apply adhesive to both bond surfaces, bushing, and carbon.
e. Install the bushing so that it’s flange lies flush against the mating carbon structure. Ensure
good adhesive squeeze-out around periphery of bushing.
f. Allow the adhesive to cure in accordance with manufacturer’s instructions.
4. If it is necessary to replace an SS-M4-RB23-4 pin, proceed as follows:
a. Use Plexus MA830 adhesive.
b. Prepare all bond surfaces (pin and carbon structure) by first cleaning with cloth and
isopropyl alcohol, then abrading with 120-180 grit aluminum oxide emery paper. Shiny bond
surfaces should be dulled by sanding, but avoid unnecessary sanding of the carbon struc-
ture or excessive clearances could result.
c. Install the replacement pins in their mating bushings in the Seawings™ tip.
d. Apply polyester flash tape or other thin release-type tape to the Seawings™ tip around the
bushings, so any excess adhesive that squeezes out of the joint will not bond the Seaw-
ings™ and tip together.
e. Mix adhesive in accordance with manufacturer’s instructions.
f. Apply adhesive to both bond surfaces (pin’s flange and carbon mating surfaces).
g. Install the Seawings™ tip. (See “Seawings™ Platform Tip Removal and Installation” on page
11-7.) Use adhesive tape as necessary to hold the tip in good alignment with Seawings™.
h. Allow the adhesive to cure in accordance with manufacturer’s instructions.
i. Remove the Seawings™ tip. (See “Repair of Seawings™ Tip Attach Pins and Bushings” on
page 11-8.)
j. Remove the protective tape and check the bond lines for signs of good adhesive squeeze
out and bond integrity.
5. Install the Seawings™ tip. (See “Seawings™ Platform Tip Removal and Installation” on page 11-7.)
