NOTES
For more detailed information, see Spins in
Section 4 - Normal Procedures.
Inappropriate use of the spin recovery
procedure, such as during stall recovery, may
induce a spin entry.
3.21 OPEN DOOR
The cabin doors on the Tomahawk are double latched; so the chances of
one springing open in flight at both the top and side are remote. However, if
improperly latched, a 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 both upper and side latches are 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 top latch is open, latch it. If the side
latch is open, pull on the arm rest while moving the latch handle to the
latched position. If both latches are open, close the side latch then the top
latch.
3.23 ENGINE ROUGHNESS
Engine roughness is usually due to carburetor icing which is indicated
by a drop in RPM, and may be accompanied by a slight loss of airspeed or
altitude. If too much ice is allowed to accumulate, restoration of full power
may not be possible; therefore, prompt action is required.
Turn carburetor heat ON (See Note). RPM will decrease slightly and
roughness will increase. Wait for a decrease in engine roughness or an
increase in RPM, indicating ice removal. If no change in approximately one
minute, return the carburetor heat to OFF.
