EMERGENCY PROCEDURES
This ON position provides a reduced fuel flow which results in lean
mixtures at two portions of the manifold pressure range. For example, at
2500 RPM excessively iean mixtures with resulting roughness and/ or
power drop off are experienced at approximately 22 inches (just before the
throttle switch activates) and again at 28 or more inches of manifold
pressure.
To avoid these areas of rough engine operation. select 2200 RPM and
sufficient manifold pressure within the green arc range for the flight
condition at hand. If more power is required, use progressively more RPM
and select a manifold pressure where smooth engine operation and normal
airspeed can be obtained.
The landing approach should be planned so that approximately 15
inches of manifold pressure can be used. If the throttle is brought back to
idle position, the mixture becomes very rich. This could cause a sluggish
power response if the throttle had to be advanced rapidly for dragging into
the airport.
LOW OIL PRESSURE
If
low oil pressure is accompanied by normal oil temperature, there is
a possibility the oil pressure gage or relief valve is malfunctioning. A leak
in the line to the gage is not necessarily cause for an immediate precau-
tionary landing because an orifice in this line will prevent a sudden loss of
oil from the engine sump. However, a landing at the nearest airport would
be advisable to inspect the source of trouble.
If a total loss of oil pressure is accompanied by a rise in oil tempera-
ture, there is good reason to suspect an engine failure is imminent. Reduce
engine power immediately and select a suitable forced landing field. Use
only the minimum power required to reach the desired touchdown spot.
LANDING GEAR MALFUNCTION PROCEDURES
In the event of possible landing gear retraction or extension malfunc-
tions, there are several general checks that should be made prior to
initiating the steps outlined in the following paragraphs.
In analyzing a landing gear malfunction, first check that the master
switch is ON and the LDG GEAR and GEAR PUMP circuit breakers are
in; reset if necessary. Also, check both landing gear position indicator
lights for operation by "pressing-to-test" the light units and rotating them
