7.11  Seats and harness belts 

The  airplane  is  equipped  with  adjustable  4-position  seats  with  rigid  structure  and  soft 
cushions. The seats are hinged at the front to a transverse beam and at the rear they are 
resting on nylon support at the lower part of the frame No.3. The seat can be readjusted or 
removed by pressing the springs of the fixing mechanism and taking the fixing pins out of 
the seat position adjustment holes. To fix the seat in a desired position align the respective 
seat position adjustment holes and the fixing pins with the springs of the fixing mechanism 
depressed and then release the springs (then the pins will move back to stops). 

The harness belts system is of 4-point type. The shoulder belts are coming from the rear 
and up and are joined to the waist belts through adjustable buckles. The waist belts have 
also a lock. 

Before climbing into the cockpit the pilots should adjust the seat position. After getting into 
the seats the pilots should fasten the belt locks and adjust the belts to their size. 

The  seats  and  harness  belts  properly  adjusted  and fastened  do  not  restrict  pilot  motions 
necessary  to  control  the  airplane  and  ensure  pilots'  safety  in  flight  and  during  airplane 
motion on the ground. 

7.12 Cockpit doors 

The cockpit doors consist of organic glass, attached to the metal tubular framework. The 
doors are hinged on top and open upward. In their open and closed position the doors are 
retained by pneumatic cylinders. Each door can be fixed in the closed position with a lock. 

Both  left  and  right  doors  have  air  scoops  for  ventilation,  de-misting  of  the  glass  and 
providing pilot view for landing in poor visibility conditions (snow, rain, etc.). 

7.13 Baggage compartment 

A-32 has baggage compartment located behind the pilot seats and accessible from inside 
of the cockpit on the ground and in flight. The compartment is formed by the frame No.3 in 
front,  by  a  rigid  partition  at  the  frame  No.5  behind,  by  fuselage  skin  on  the  sides  and 
bottom and by a fabric flap with zipper on top. The baggage compartment volume is 160 l 
(42 US gal). The weight of baggage in the compartment may not exceed 30 kg (66 lb). 

7.14 Recovery system 

This  aircraft  is  optionally  equipped  with  a  quick-acting  MAGNUM  601  S-LSA  recovery 
system.  The  system  is  intended  for  rescue  of  pilots  together  with  the  aircraft  in  case  of 
emergency situation in flight, when emergency landing is impossible (see section 

3.2.5

) 

Installation of the recovery system is shown on 

Fig. 22

The parachute packed into a soft 

container (1) is located behind the baggage compartment. To deploy the system pull the 
handle (2) of the ejection device connected with a cable (3) to the rocket housing (4). That 
launches the rocket which pulls out the parachute, attached with a rope (5) via a carabiner 
(6) to the cables (7) and (9) fastened to the attachment points (8) and (10). The locations 
of  the  attachment  points  and  the  cables'  length  are  selected  so  that  the  aircraft  when 
descending with deployed parachute is suspended in a certain attitude (wings level, nose 
lowered). Such attitude ensures a high level  of safety to pilots  during emergency landing 
despite  the  fact  that  the  aircraft  structure  is  likely  to  be  damaged  while  absorbing  the 
impact at touchdown.
