Check the fit of the duct in between the footwells, and if necessary adjust the width of the duct, then
rivet the CD1, CD2 and CD3 sections together using TAPD46BS rivets.
Rivet sealing strip to the bottom sides of the duct using TAPD46BS rivets with EUR011 load
spreading washers to prevent the rivets pulling through the sealing material.
The assembled duct is fitted to the footwell using three bolts each side. The height and angle of the
duct should be arranged to provide a clearance underneath the exhaust silencer of approximately 5
mm, and be arranged to fit the air intake opening in the lower cowling. See figure 2.
A single AN3-5A bolt screws the side of the duct onto the inside face of the footwell using an
MS21047-3 anchor nut, installed in reverse into the footwell using TAPK 36 BS rivets to make it
nearly flush; the brackets CD4 and CD5 are then bolted to the duct and to the front faces of the
footwell, again using AN3-5A bolts - these should have AN970-3 washers to spread the load into the
fibreglass structure, and MS21042-3 stiffnuts.
