Low Oil Pressure; Retraction Malfunctions; Landing Gear Malfunction Procedures - Cessna TR182 1979 Pilot Operating Handbook

CESSNA
MODEL TR182
SECTION 3
EMERGENCY PROCEDURES
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 at the
same time to check for open dimming shutters. A burned-out bulb can be
replaced in flight by using the bulb from the remaining gear position
indicator light.
RETRACTION MALFUNCTIONS
If
the landing gear fails to retract normally, or an intermittent GEAR
UP indicator light is present, check the indicator light for proper operation
and attempt to recycle the landing gear. Place the landing gear lever in the
GEAR DOWNposition. When the GEAR DOWNlight illuminates, reposi-
tion the gear lever in the GEAR UP position for another retraction attempt.
If
the GEAR UP indicator light still fails to illuminate, the flight may be
continued to an airport having maintenance facilities, if practical. If gear
motor operation is audible after a period of one minute following gear
lever retraction actuation, pull the GEAR PUMP circuit breaker switch to
prevent the electric motor from overheating. In this event, remember to re-
engage the circuit breaker switch just prior to landing. Intermittent gear
motor operation may also be detected by momentary fluctuations of the
ammeter needle.
