Land on the remaining runway, if possible; otherwise, prepare to land
straight ahead, making small turns to avoid obstacles. Only if enough
altitude and airspeed are available can a 180° turn be made to return
to the airfield. You are much more likely to survive an emergency
straight-ahead forced landing of the plane than a stall and spin resulting
from a steep, slow turn back to the field.
Only if there is time and you have maintained control of the aircraft
should you attempt to restart the engine. Pull the carburetor heat on (if
applicable) and make sure that the mixture control is in the full rich
position, the fuel valve is on and the magneto switch is in the “BOTH”
position.
3-4.1.3 Engine Failure During Flight
If loss of power occurs at altitude and if your Sportsman is equipped
with a constant-speed propeller, immediately (while there is still enough
oil pressure to operate the prop) pull the propeller control to the full aft
(coarse pitch) position to reduce drag. Trim the aircraft for best gliding
speed (80 kts./92 m.p.h.), and attempt to restart the engine by applying
carburetor heat (if applicable), moving the mixture control to the full
rich position and checking that the fuel valve is on and the magneto
switch is in the “BOTH” position. If the engine fails to restart, prepare
to execute a forced landing.
More common than a complete engine failure is engine roughness,
which may be caused by a bad magneto, induction problems, improper
leaning, plug fouling, fuel starvation, carburetor icing, water in the fuel,
etc. If you encounter engine roughness or power loss in flight, check
all engine gauges to verify that the pressures and temperatures fall
