10.3 Engine cowlings
a) Assemble the two cowling parts. Offer up first and verify that the two parts fit
snugly together. Some sanding on the edges may be necessary for a perfect
fit. When happy and initially held together with tape, carefully drill the fixing
holes. There should be guide marks, but if these are not present or very faint,
start by drilling a forward hole each side 30mm outboard from the position
where the cowling changes angle as shown below, and 10mm up from the
upper cowling edge.
Cleco / Skinpin together, then mark the other holes starting with the rear one,
which should be 50mm forward of the rear edge. Then mark the remaining 3
holes (5 in total) with even spacing (this will be approximately 170mm). Drill
and fix with Clecos/Skinpins or 4mm nuts and bolts. Starting from the front and
working backwards will give the best results with less chance of bulging
between fixings.
