1.1 Cowling

Powerplant cowling consists of two parts: fiberglass nose section and light alloy panel on
top and all fiberglass bottom.

Top cowling is easily removed by releasing four latches, two on each side.

Removal of lower portion is just as easy by quick release of two side pins and two latches
located on bottom. Figure D-1 below shows cowling version featuring ram intake and
landing light.

Before removing cowling, disconnect landing light wiring and ram intake air hose from
heat exchanger (optional).

If any cracks are detected, immediately drill stop holes at crack ends. Air circulation is
provided by front openings in nose section and by an outflow area on the underside by the
firewall.
