2.1.2.1 Cowl Flap C42 Serie / C52
I. General:
Cowl flap for C42B/C and C52 allows to considerably shorten warm-up period of
the engine and to keep oil cylinder head temperature during flight operations in
optimal range of 90-110°C.
Annoying covering of the cowl flap in cold weather is a thing of the past. As a
result, optimally regulated engine temperatures as well as shortened warm-up
period of the engine minimizes fuel consumption and prolongs the life span of
the engine.
Installed temperature warning sensor (red warning light) will notify that the flap
is not opened.
II. Mechanical Installation:
- Dismantle lower cowling.
- Put on the housing of the cowl flap and fix it with 2 bolts M4 at the upper and
lower inlet lips.

- In flight direction left, about 10 cm from below cut a slot for the Bowden cable
in the GRP sealed radiator surface of the cowling (e.g. with a small drill or
round file)
.
