DESIGN FEATURES
The MOONEY EXECUTIVE 2lis alow-wingfour-place air-
craft with a retractable gear. A four-cylinder engine powers
the aircraft for economical, high-performance flight. Li-
censing under Federal Aviation Administration regulations
assures that your Mooney meets the requirements of Nor-
mal Category aircraft.
AIRFRAME
The airframe has a welded, tubular- steel cabin structure en-
closed in sheet-aluminum skins. Stressed skins rivet to
main and auxiliary spars in the wing,· stabilizer, and ver-
tical fin. The laminar- flow wing has full wrap- around skins
with flush riveting over the forward top two thirds of the
wing area.
For pitch trim control, the empennage pivots on the aft fuse-
lage. A torque-tube-driven jack screw, bolted to the rear
tail cone bulkhead, sets the stabilizer angle.
The forward-opening cabin door provides access to both
front and rear seats. The baggage compartment door is
above the wing trailing edge to enable baggage loading from
the ground.
POWER PLANT
The power plant is a four-cylinder fuel-injected engine that
develops 200 horsepower. A 60-ampere 12-volt alternator
supplies ample electrical power for all standard and option-
al equipment at all engine speeds from warmup to flight
power settings.
The hydraulic propeller governor, using oil pressure for
increasing blade pitch to control engine speed, regulates
the controllable-pitch constant- speed propeller. Spring
and blade aerodynamic forces decrease blade pitch.

FLIGHT CONTROLS
Conventional dual controls link to the control surfaces
through push-pull tubes. The co-pilot's rudder pedals are
removable.
The Mooney Positive Control (P. C.) system is standard
equipment, P. C. is a lateral stability augmentation system
that provides a high degree of roll and yaw stability, thereby
enhancing the inherent wings- level flight characteristics
of the aircraft. The system works full time from takeoff
through landing but can be easily deactivated or overpowered
for flight maneuvers. P.C. allows you, the pilot, to devote
more time to navigation, traffic surveillance, and com-
mu' iications.
LANDING GEAR
The tricycle landing gear allows maximum taxi vision and
ground maneuvering. Hydraulic disc brakes and a steer-
able nose wheel aid in positive directional control during
taxiing and crosswind landings.
The landing gear is electrically retracted. A gear warning
horn along with amber and green positfon lights help prevent
inadvertent gear-up landings. The retraction system in-
corporates an airspeed-actuated switch that prevents gear
retraction until a safe airspeed is attained. An emergency
gear extension system_ is provided.
