Extension Malfunctions; Gear Up Landing; Electrical Power Supply System Malfunctions - Cessna TR182 1979 Pilot Operating Handbook

SECTION 3
EMERGENCY PROCEDURES
CESSNA
MODELTR182
EXTENSION MALFUNCTIONS
Normallanding gear extension time is approximately
5
seconds. If the
landing gear will not extend normally, perform the general checks of
circuit breakers and master switch and repeat the normal extension
procedures at a reduced airspeed of 100KIAS. The landing gear lever must
be in the down position with the detent engaged. If efforts to extend and lock
the gear through the normal landing gear system fail, the gear can be
manually extended (as long as hydraulic system fluid has not been
cmnpletely lost) by use of the emergency hand pump. The hand pump is
located between the front seats.
A checklist is provided for step-by-step instructions for a manual gear
extension.
If
gear motor operation is audible after a period of one minute
following gear lever extension actuation, pull the GEAR PUMP circuit
breaker to prevent the electric motor from overheating. In this event,
remember to re-engage the circuit breaker just prior to landing.
GEAR UP LANDINGS
If the landing gear remains retracted or is only partially extended, and
all efforts to fully extend it (including manual extension) have failed, plan
a wheels-up landing. In preparation for landing, reposition the landing
gear lever to GEAR UP and push the LDG GEAR and GEAR PUMP circuit
breakers in to allow the landing gear to swing into the gear wells at
touchdown. Then proceed in accordance with the checklist.
ELECTRICAL POWER SUPPLY SYSTEM
MALFUNCTIONS
Malfunctions in the electrical power supply system can be detected by
periodic monitoring of the ammeter and low-voltage warning light;
however, the cause of these malfunctions is usually difficult to determine.
A broken alternator drive belt or wiring is most likely the cause of
alternator failures, although other factors could cause the problem. A
damaged or improperly adjusted alternator control unit can also cause
malfunctions. Problems of this nature constitute an electrical emergency
and should be dealt with immediately. Electrical power malfunctions
usually fall into two categories: excessive rate of charge and insufficient
rate
of
charge. The paragraphs below describe the recommended remedy
for each situation.
