EMERGENCY PROCEDURES
The cabin door is latched through a pin mechanism, so the chances of its
springing open in flight is remote. However, should you forget to fully engage
the door latch, the door may spring partially open. This will usually happen at
takeoff or soon afterward. A partially open door will not affect normal flight
characteristics, and a normal landing can be made with the door open.
If the door latch is open, the door will trail slightly open, and airspeed will
be reduced slightly.
To close the door in flight, slow the airplane to 90 KIAS, close the cabin
vents and open the storm window. If the door latch is open, pull on the
armrest while moving the latch handle to the latched position.
3.37 ENGINE ROUGHNESS
Engine roughness may be caused by dirt in the injector nozzles,
induction filter icing, or ignition problems.
First adjust the mixture for maximum smoothness. The engine will run
rough if the mixture is too rich or too lean.
Move the alternate air to OPEN and then turn ON the electric fuel
pump.
Switch the fuel selector to another tank to see if fuel contamination is
the problem.
Check the engine gauges for abnormal readings. If any gauge readings
are abnormal proceed accordingly.
Secure (OFF) one magneto at a time, then back to ON. If operation is
satisfactory on either magneto, proceed on that magneto at reduced power
with full RICH mixture to a landing at the first available airport.
If roughness persists, prepare for a precautionary landing at pilot's
discretion.
