10.2 Firewall and scuttle moulding
Next steps are to position the firewall and scuttle moulding before assembling the
forward cowling pieces.
Fig 182 Firewall components, and installed firewall (engine removed for clarity)
a) Fit the firewall halves in position behind the engine. Attach the two halves
using cleco‟s / skinpins for initially fitting.
b) Firewall should fit in position as shown below. Firewall should sit behind the
reference bolt shown and top edge should be 95mm above its centre. Attach
the small rubber edging to the edges of the cut outs where it sits in close
proximity to the fuselage frame. If necessary file the cut outs to give space for
this so position is maintained. Fix into position using the small angle brackets
390/390-1using 4mm aluminium rivets.
