ENGINE LUBRICATION
Engine oil is in a tank incorporated into the power plant. It ensures lubrication
and engine cooling. A cooler located on left side in engine compartment
maintains oil temperature within limits. Oil flow into the cooler is metered by a
thermostatic valve. Engine oil also supplies propeller governor and engine
torquemeter.
Lubrication system content, cooler included, is 12.7 quarts (12 litres). A
graduated dipstick allows checking oil quantity in system. A visual oil sight
glass, located on engine left side, allows a rapid checking of oil level.
NOTE :
For checking and oil filling–up, refer to Section 8.
ENGINE STARTING (Figure 7.6.4)
Ignition function
Ignition system consists of an ignition unit and two spark igniter plugs in
power plant, a three–position ”IGNITION” switch ”OFF – AUTO – ON” located
on ”ENGINE START” panel at upper panel and ”IGNITION” warning light
located on advisory panel.
Ignition unit supplies, from 28–Volt source, high voltage current necessary to
spark igniter plugs. When ”IGNITION” switch is positioned to ”AUTO”, ignition
unit supply is ensured as long as ”STARTER” switch located on left side of
”IGNITION” switch is maintained ”ON” : this is normal procedure for ground
starting or flight air start with starter.
”ON” position for ”IGNITION” switch is used in case of flight air start without
starter. In this configuration, ignition unit is supplied permanently. In any
case, ”IGNITION” warning light illuminates as long as ignition unit is supplied.
