10.8.1 All engine exhaust systems shall be adequate
to assure the correct functioning of the machinery and that safe operation
of the craft is not put at risk.
10.8.2 Exhaust systems shall be so arranged as
to minimize the intake of exhaust gases into manned spaces, air-conditioning
systems, and engine intakes. Exhaust systems shall not discharge into
air-cushion intakes.
10.8.3 Pipes through which exhaust gases are discharged
through the hull in the vicinity of the waterline shall be fitted
with erosion-/corrosion-resistant shut-off flaps or other devices
on the shell or pipe end and acceptable arrangements made to prevent
water flooding the space or entering the engine exhaust manifold.
10.8.4 Gas turbine engine exhausts shall be arranged
so that hot exhaust gases are directed away from areas to which personnel
have access, either on board the craft or in the vicinity of the craft
when berthed.
