Engine lubrication system is made with the dry sump. Engine lubrication system is equipped
with the mechanically driven oil pump (3, Fig. 10-4a/b) with oil filter (6) which ensures oil supply
from the oil tank (4) located on the firewall through the thermostatic valve (9) and the oil cooler
(5) to the lubricated points on the engine. The oil pump is equipped with the pressure relief valve
(1) and with the oil pressure sensor (2). The oil tank is ventilated by venting (7), which is
connected to hose and is led under the airplane. Oil pressure and temperature are indicated
