When the landing gear selector switch is placed in the DOWN position. the hydraulic pressure lock
is released and hydraulic fluid is directed to the down side of the landing gear actuator cylinders
extending the gear until the pressure switch is actuated. When the pressure switch is actuated the
hydraulic power pack pump is shut off and all three gears are held in the down lock position by
over center braces assisted by trapped hydraulic pressure. A ground contact switch on the right
main gear. assists in preventing landing gear retraction while on the ground caused by an
unintentional positioning of the landing gear selector switch to the UP position.
Landing gear position indicators and a warning horn system are provided to alert the pilot when the
landing gear is in the up. or down and locked position. Position indicators are installed in front of
the pilot near the gear selector switch. These indicators are individual red and green lights. (SIN
1454 I thru 14624) or the indicators on the annunciator panel (SIN 14625 and subsequent). The
gear down position is indicated by three green lights. The unsafe red (GEAR WARN) light indicates
the gear is in transit or not fully down and locked. There is no electrical indication of gear being
fully retracted other than all indicator lights being extinguished. When the landing gear extends to
the full down position three landing gear down switches are actuated causing the green lights to
illuminate. indicating the gear is down and locked.
6.4 BAGGAGE COMPARTMENT
The baggage compartment is located in the aft portion of the cabin area. Access is through the
baggage door on the left side of the airplane. or through the cabin area behind the rear passenger
seats. Volume of the baggage compartment is twenty two (22) cubic feet and maximum allowable
baggage weight is two hundred (200) pounds. When loading the airplane, refer to the Weight and
Balance section of the Pilots Operating Handbook to assure that airplane loading meets all
requirements and restrictions. All loads should be securely fastened using the cargo net and the
tie-down rings (4) located in the comers of the baggage compartment, to prevent movement
during airplane operations.
CAUTION: Passengers should not be allowed to ride in the baggage compartment under any
circumstances. Do not carry hazardous material.
6.5 IGNITION SYSTEM
The engine is equipped with dual magnetos. The two magnetos provide two independent ignition
systems for the engine. Each ignition system has a shielded harness assembly and a set of radio
shielded spark plugs. Each cylinder utilizes two (2) spark plugs. The left magneto fires the bottom
spark plugs in cylinders one (1) three (3) and five (5), and the top plugs in cylinders two (2) and
four (4) and six (6). The right magneto provides spark for the opposite spark plugs.
INDUCTION AIR SYSTEM
Induction ram air for the engine comes from the outside corner of the left engine cooling air inlet.
This air flows through ductwork to an air box which holds an air filter and then through further
ductwork to the engine throttle body. Heated engine cooling air below the cylinders can be routed
to the induction system through a door downstream of the:: filter, controlled by the pilot with the
ALT AIR push-pull control to provide an alternate source of air to the engine should the filter
become blocked.
