3.7.12 PROPELLER OVERSPEED
If the propeller governor should fail, allowing the propeller pitch to flatten, the engine will
overspeed. In this instance, close the throttle immediately and reduce airspeed. As the situation
stabilizes, use the throttle to control engine speed as though the propeller had a fixed pitch.
Proceed to the nearest airport at reduced airspeed and power, observing the engine rpm limits.
3.7.13 LANDING GEAR MALFUNCTIONS
There are several checks that should be made in the event of a landing gear malfunction. Check
landing gear circuit breakers in; reset if necessary. Check inoperative gear position light for
possible bulb failure using the press-to-test switch.
If a positive gear down and locked indication cannot be obtained with normal extension procedures
repeated one additional time, proceed with emergency gear extension procedures. A positive gear
extension is indicated by:
1)
Green locked lights.
2)
Absence of red gear warn light and
3)
Absence of gear warning horn with throttle idle or flaps full down.
3.7.14 ELECTRICAL SYSTEM MALFUNCTIONS
After periods of heavy usage, such as prolonged cold weather starts or extended periods
overtaxing, the battery charge level will have dropped low enough to accept higher than normal
charge rates during the initial part of the flight. However, after approximately 30 minutes, the
ammeter indication should have decreased steadily toward a zero reading and the voltmeter should
indicate between 24 and 30 volts.
If the charging rate remains above this value for an extended period of time, there is a possibility
that the battery may overheat and evaporate electrolyte at an excessive rate. To preclude the
possibility of an overcharging condition affecting the battery, the alternator master switch should
be turned off and the flight terminated. Electrical load should be reduced to an essential minimum
if an immediate landing is impractical.
A continuous discharge rate shown on the ammeter during flight accompanied by the eventual
illumination of the Low Volts light generally indicates:
1.
Alternator and/or voltage regulator malfunction. or
2.
Excessive load on the electrical system.
First, the electrical load must be reduced. If the ammeter continues to show a discharge, the
alternator master switch should be turned off to isolate the alternator from the electrical system.
With the alternator off the entire electrical load is placed on the battery and all non-essential
electrical equipment should be turned off to reduce the discharge rate of the battery.
When operating with both the battery master and alternator master switches OFF it should be
remembered that certain electrical equipment will be inoperative, such as :
1.
Wing flaps
2.
Landing gear operating system (except emergency extension system)
3.
Landing gear lights and warning system
4.
Fuel gages
5.
Engine temperature gauges
