FORCED LANDINGS
Select a suitable landing site and proceed to it. If all attempts to restart the engine fail
and a forced landing is imminent, follow the checklist for Emergency Landing Without
Power.
Before attempting an off airport landing with engine power available, fly over the landing
site at a safe but low altitude to inspect the terrain. Check for obstructions and surface
conditions. Plan your approach and touch down.
When preparing to ditch, it is advisable to jettison any heavy objects from around the
Pilot, including heavy clothing. Of course, if time permits, ditch as close to land or a
water vessel as possible.
Transmit Mayday message on 121.5 MHz giving location and intentions.
RECOVERY FROM A SPIRAL DIVE
If a spiral dive is encountered, proceed as follows:
(1)
Retard Throttle to
IDLE.
(2)
Stop the turn by using coordinated aileron and rudder in opposite
direction of spiral dive.
(3)
Cautiously apply elevator back pressure to slowly reduce the airspeed to
below maneuvering speed .
SPINS
Intentional spins in the S-7LS aircraft are
PROHIBITED
. Should an inadvertent spin
occur, the following recovery procedure should be used:
(1)
Retard the throttle to
IDLE.
(2)
Place the ailerons in the
NEUTRAL
position.
(3) Apply
and
HOLD
full rudder opposite to the direction of rotation.
(4)
Just after the rudder pedal reaches the stop, move the control stick (yoke)
forward far enough to "break" the stall.
(5)
Hold these control inputs until rotation stops.
(6)
As rotation stops, neutralize rudder and apply back pressure on the
control stick to slowly reduce airspeed to normal cruise speed.
ROUGH ENGINE OPERATION
IGNITION MALFUNCTION
A sudden engine roughness or misfiring is usually evidence of ignition problems.
Switching form BOTH to either L or R ignition switch position will identify which circuit is
malfunctioning. Select different power settings if continued operations on BOTH circuits
is practicable. If not, switch to the good circuit and proceed to the nearest airport for
repairs.
