EMERGENCY PROCEDURES
APPROVED
WARNING:
If there is a strong smell of fuel in the cockpit, divert to the
nearest suitable landing field. Fly a forced landing pattern and shut down the
engine fuel supply once a safe landing is assured.
The following procedure provides guidance to determine and correct some
of the conditions contributing to a rough running engine or a partial power
loss:
1 Fuel Selector SWITCH TANKS
Selecting the opposite fuel tank may resolve the problem if fuel starvation
or contamination in one tank was the problem.
2 Throttle Lever SWEEP
Move the Throttle Lever through the complete range to obtain the best
operation possible.
3 Ignition Switch BOTH, L, then R
Cycling the ignition switch momentarily from BOTH to L and then to R
may help identify the problem. An obvious power loss in single ignition
operation indicates ignition system or spark plug trouble. Return ignition
switch to the BOTH position unless extreme roughness dictates the use
of a single ignition circuit.
4 Land
AS SOON AS
POSSIBLE
3.4.4 LOW OIL PRESSURE
If low oil pressure is accompanied by a rise in oil temperature, the engine
has probably lost a significant amount of its oil and engine failure may be
imminent. Immediately reduce engine power to idle and select a suitable
forced landing field.
!
Prolonged use of high power settings after loss of oil pressure will lead to
engine mechanical damage and total engine failure.
NOTE
:
Full power should only be used following a loss of oil pressure when
operating close to the ground and only for the time necessary to climb to an
altitude permitting a safe landing or analysis of the low oil pressure indica-
