WARNING
The fuel lift pipe in each fuel tank is situated adjacent to the lower inside wall of the
tank. The aircraft should at no time be subjected to a sustained side slip towards a
near empty fuel tank (i.e. - wing with near empty tank down) as, despite the
baffling, this may have the consequence that the fuel runs towards the outer edge
of the tank exposing the fuel lift pipe (to suck air), thereby starving the engine of
fuel leading to engine stoppage. This poses a particular threat when at low altitude,
typically prior to landing
.
WARNING
If a fuel lift pipe is exposed to air, the pump will suck air into the engine
(from the empty tank) and engine stoppage will result. When one tank is
empty, or close to empty, the fuel selector valve should be switched to the
fullest tank.
Avoid operation below the normal operational oil temperature (90 to
110 °C / 194 to 230 °F).
CAUTION
It is not advisable to reduce the engine throttle control lever to minimum on final
approach or when descending from very high altitude. In such cases the engine can
become over-cooled, although unlikely, and a loss of power may occur. Descent at
increased idle (approximately 3000 rpm), speed between 65 to 85 KIAS and verify
that the engine instruments
indicate values within permitted limits.
