Task Instructions
1. Inspect the boot for any damage such as holes, tears, or excessively worn spots. If damage is unacceptable, replace the boot using the MLG Boot Replacement Procedure. (Main Landing Gear (MLG) Boot Removal) If the boot is good, proceed with the steps below.
2. Pull on the flange of the boot where it has become disbonded, testing the surrounding area for bond strength. The boot should have good adhesion to the substrate. If the disbonded area can easily expanded, continue separating the boot from the substrate until the limits of area of low adhesion have been reached. If after this exercise, the entire boot has been separated, proceed to the steps of the Boot Replacement Procedure (Main Landing Gear (MLG) Boot Installation) that involve boot and substrate preparation and bonding.
3. Clean the area around the repair of any water, mud, or other foreign material.
4. With a putty knife, wood chisel, or similar tool, carefully remove excess boot adhesive from the surface of the boot and substrate in the disbonded area. Do not cut, scratch, or otherwise damage the surfaces. There is no need to completely remove all adhesive, but any loose or excessively thick material should be removed.
5. Clean the bonding area surfaces of boot and substrate with isopropyl alcohol and a clean cloth. A cotton swab or similar tool may be useful for getting into the edges.
6. Prop the disbonded area open and allow the alcohol to completely dry.
7. Bond the boot to the substrate by injecting or by lifting and troweling Sil-Poxy adhesive into the joint. Use care to ensure a good seal completely across the interface and into the edges.
Note: 
The working time of Sil-Poxy is five minutes. Each bonding operation must be completed in this time or the strength of the joint may be reduced. Conform to the instructions and safety procedures of the adhesive manufacturer.
Wipe off excess adhesive with a paper towel. Allow adhesive to cure for at least 24 hours at room temperature before returning aircraft to service.
Verification Method
MLG boot is securely bonded to both landing gear leg and Seawings™ with no areas of delamination.
