Winches and other deck gear may be protected by fitting heated metal cowlings over the equipment and tubular heaters can be installed inside the mast.
They are manufacturers of aeroplane tanks, cowling, fairings pilot seats and things of that kind, but they can get no orders.
On the other hand, such a cowling interferes with the normal air cooling of the engine, and the only way of determining the balance is that of full-scale tests.
A new cowling was used, introducing shock-mounts that transmitted lower noise levels to the cockpit and reduced cowl cracking.
As the result, the engine was prone to overheating and to deal with this the cowling flaps restricting airflow around the engine were removed.
Specific differences included wheel spats, a redesigned engine cowling molded of fiberglass, and aluminum ailerons and flaps.
The landing gear consists of a monowheel gear which retracts forward into a fibreglass cowling.
The landing gear legs, fuel tank, wink tips, wheel pants, and cowling were also formed out of fibre-glass.
