The engine mount connects the power unit to the airplane. It is welded from 4130 steel tubes
and is attached to the firewall and to the engine by means of bolts. The engine mount is
installed on the firewall by four attachments through rubber shock absorbers. The scheme of
engine mount attachment to the firewall and to the engine is shown in the Fig. 10-1.

10.2.1.6 Engine cowling
Engine cowling (Fig. 10-2) consists of two parts: upper cowling and lower cowling. The upper
cowling (1) is attached by means of quick fasteners (4) to the firewall and to the lower cowling
(2). Unlock the quick fasteners by turning the bolt by 90° counter–clockwise. The access
cover (5) which is located on the upper cowling on the left side in front of the firewall enables
to check oil quantity in the oil tank without removing the upper cowling.
The lower cowling (2) is attached by means of quick fasteners (4) to the firewall and to the
upper cowling (1). There is in the front part of the lower cowling (2) an oval hole (3) for air
inlet to the oil radiator. In the bottom part of the lower cowling (2) is NACA inlet for air intake
to the water cooler.
