craft with
a
retractable gear. A four-cylinder engine powers
the aircraft for economical, high-performance flight.
1,i-
censing under Federal Aviation Agency regulations assures
that your Mooney meets the requirements of Normal Cate-
gory aircraft at full gross weight.
AIRFRAME
The airframe has awelded, 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 two thirds of the wing
area.
For pitch trim control, the empennage pivots on the aft fuse-
lage.
A
torqueAube-driven jack screw, bolted to tie rear
tail cone bulkhead, sets the stabilizer angle of attack.
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
50-ampere 12-volt generator
supplies ample electrical power for
all
standard and optional
equipment
whenthe engine
is
operating at flight power set-
tings.
The hydraulic propeller governor, using engine oil pressure
fpr increasing blade pitch to control engine speed, regulates
the controllable-pitch constant- speed propeller. Spring. and
blade aerodynamic forces decrease blade pitch.
