7. Access doors
To enable access to check oil and coolant before flight, two hinged doors are required in the top
cowling. See figure 1.
The doors themselves are cut from the cowling, so mark out 12cm (4¾") squares centred over both
the water expansion tank (not to be confused with the optional overflow bottle) and the oil tank.
Carefully cut the door panel from the cowling with a knife or thin hacksaw blade to minimise the gap
around it.
The scribed outline of a NACA inlet on the top cowling is for the Rotax 912/S engine. You can
ignore this.
Flange
Reposition the door panels in the openings as accurately as possible and tape them temporarily in
place from the outside.
Scuff sand the inside of the cowling around the door panels. Cover the door panel with plastic
sheeting to act as a release agent.
Lay up four plies of ‘bid’ at +/- 45
o
around the door panels lapping onto the cowling approximately
2-3cm (1").
