Do not pull out of the resulting dive too
abruptly. This could cause excessive wing
loads and possibly a secondary stall.
5. Pull out of dive by exerting a smooth,
steady back pressure on control wheel,
excessive aircraft stresses.
Maximum airspeed (red line) Vmo/Mmo is
259 KIAS or 0.52 Mach. Flight characteristics are
conventional throughout a dive maneuver. However,
caution should be used if rough air is encountered after
maximum allowable dive speed has been reached.
Dive recovery should be very gentle to avoid excessive
8A-52. MANEUVERING FLIGHT.
Maneuvering speed (Va) at which full abrupt
control inputs can be applied without exceeding the
design load factor of the aircraft is shown in Chapter 5.
The data is based on 12,500 pounds and there are no
restrictions below this weight. There are no unusual
characteristics during accelerated flight.
8A-53. FLIGHT CONTROLS.
The aircraft is stable under all normal flight
conditions. Aileron, elevator, rudder, and trim tab
controls function effectively throughout all normal flight
conditions. Elevator control forces are relatively light in
the extreme aft Center of Gravity (CG) condition,
progressing to moderately high with CG at the forward
limit. Extending and retracting the landing gear causes
only slight changes in control pressure. Control
pressures resulting from changing power settings or
repositioning the flaps are not excessive in the landing
configuration at the most forward CG. The minimum
speed at which the aircraft can be fully trimmed is
92 KIAS (gear and flaps down, propellers at high
RPM). Control forces produced by changes in speed,
power setting, flap position and landing gear position
are light and can be overcome with one hand on the
control wheel. Trim tabs permit the pilot to reduce
control forces to zero. During single-engine operation,
the rudder boost system aids in relieving the relatively
high rudder pressures resulting from the large
asymmetry in power.

Section V. ADVERSE ENVIRONMENTAL CONDITIONS
The purpose of this section is to inform the pilot
of the special precautions and procedures to be
followed during the various weather conditions that
may be encountered in flight. This section is primarily
narrative; only those checklists that cover specific
procedures characteristic of weather operations are
included. The checklist in Section II provides for
adverse environmental operations.
8A-56. COLD WEATHER OPERATIONS.
Operational difficulties may be encountered
during extremely cold weather, unless proper steps are
taken prior to or immediately after flight. All personnel
should understand and be fully aware of the necessary
procedures and precautions involved.
For ground operations conducive to ice
accumulation on landing gear structure,
use undiluted defrosting fluid on brakes
and tires to reduce the tendency of ice
accumulation during taxi, takeoff, and
