3.4.11 OVERVOLTAGE
With the engine running, the alternator is capable of
raising the bus voltage to dangerously high levels. The
voltage regulator limits the bus voltage to between 13.5
and 15.3 volts. If the bus voltage rises above 15.3 volts,
the voltage annunciator will illuminate. If this occurs, the
master switch must be turned off immediately.
Wait for at least a minute and switch master switch on
and monitor the voltage (if able) to determine whether the
regulator has reset itself. If the annunciator illuminates
again, turn the master switch off and plan to continue
flight without using the electrical system.
3.4.12 INADVERTENT SPIN
If an inadvertent spin is entered, close the throttle,
neutralize the ailerons and apply full rudder opposite to
the direction of the spin. Move the elevator control
forward to break the stall after applying the rudder. When
the rotation stops, neutralize the rudder, relax the forward
pressure on the elevator control as required to smoothly
regain level flight, and return to initial power setting. If the
flaps were down, retract them once a safe speed has
been attained. Ensure that the maximum flap speed is
not exceeded.
CAUTION
This recovery procedure is applicable only when the
aircraft is in a spin. Application of controls as
described above during a stall or after the aircraft
has stopped gyrating may cause the aircraft to enter
into a spin.
